As best shown in
Propulsion for the rocket 28 may preferably be achieved through the use of air 30 at high pressure that is provided by the pressurizer 16 and that is stored in the air chamber 20. The high pressure air 30 is released from the air chamber 20 into the launcher 14 to propel the rocket 28 into the sky and away from the launcher 14. The pressurizer 16 may have stored within it high pressure air 30, such as with a compressed air tank, or the pressurizer 16 may create the high pressure air 30. In one embodiment the pressurizer 16 is an electric air compressor 16 that is stored in the launch housing 12. The electric air compressor 16 converts power into potential energy stored in pressurized air.
In one embodiment the pressurizer 16 is powered by the power supply 18, which is also preferably located within the launch housing 12. Preferably, the power supply 18 is a rechargeable battery, such as a lithium ion battery or a lead acid battery. Alternately, non-rechargeable batteries may be utilized to supply power to the electric compressor. Further alternately, the power supply 18 need not be a battery, but instead may be a generator or simply the electricity provided from a standard wall outlet.

As shown in
The launcher 14 is a component that retains the rocket 28 and which directs the compressed air 30 released from the air chamber 20 to the rocket 28. Preferably, the launcher 14 is secured to the launch housing 12 at the exit to the air chamber 20. And, most preferably, the release member 24 is provided between the exit to the air chamber 20 and the launcher 14. In one embodiment the launcher 14 is a cylindrical component having an outer wall 32 and an inner cavity 34, such as a tubular member. The compressed air 30 that is expelled from the air chamber 20 and through the release member 24 preferably enters the inner cavity 34 of the launcher 14. In one embodiment the launcher 14 is removably fixed to the exit of the air chamber 20, such as by a male/female mating arrangement, via a bayonette connection, via a threaded connection, via a hinge and fastener, or by some other relationship that allows for removably fixing the launcher 14 to the exit of the air chamber 20 with the release member 24 therebetween.
The rocket 28 is fitted onto the launcher 14 prior to launch. Once on the launcher 14, the rocket 28 is able to receive the pressurized air 30 from the air chamber 20, which provides the propulsion for the rocket 28. In one embodiment, the rocket 28 is a tubular member having an outer wall 36 and an inner cavity 38. In one embodiment, as shown in
In an alternate embodiment as shown in

Prelaunch activities include activities that enable the rocket 28 to be launched, and that provide for a better user experience for the operator and those viewing the rocket launching system 10. One of the prelaunch activities is to open a switch to provide power from the power supply 18 to the pressurizer 16 to turn the pressurizer 16 on. When the pressurizer 16 is turned on the pressurizer 16 will provide compressed air 30 into the air chamber 20. Additional optional prelaunch activities include the creation of smoke by a smoker 22, the creation of noise or rocket rumble by a rumble making apparatus 46, and the counting down of the rocket launch by an audible count down timer 48, however additional prelaunch activities may also be provided.
The preferred smoker/fogger 22 is a traditional fog machine that creates fog or smoke by vaporizing water and glycol-based or glycerin-based fluids. The fluid is referred to as smoke juice or fog juice, and it vaporizes or atomizes inside the fog machine 22. Upon exiting the fog machine 22 and mixing with the cooler outside air the vapor condenses, resulting in a thick visible fog or smoke. As shown in
As explained above, another of the prelaunch activities is to provide a rumble noise and rumble feel (i.e., vibration), similar to what a spectator would feel and hear prior to a real rocket launch. In one embodiment, an offset or vibrating motor (not shown) is used to create the vibration and rumble noise. The vibrating motor may be located either in the controller 26 or in the launch housing 12. In one embodiment, the vibrating motor is a small motor that is improperly balanced. Furthermore, in one embodiment, there may be an off-centered weight attached to the motor output shaft that causes the motor to wobble. The amount of wobble can be changed by the amount of weight that is attached to the output shaft, the weight's radial distance outwardly from the shaft, and the speed at which the motor shaft rotates. Further, the offset weight may contact the housing, either the inside of the housing of the controller 26 or the inside of the launcher housing 12, to create additional rumble noise and vibration.
The audible countdown timer 48 may be provided either in the controller 26 or the launch housing 12, however in a preferred embodiment the countdown timer 48 is in the controller 26. The audible countdown timer 48 is preferably timed with the filling of the air chamber 20 with pressurized air 30 and the subsequent rupture/opening of the release member 24 such that when the countdown timer 48 reaches “0” or “liftoff”, the air chamber 20 will be properly pressurized and the release member 24 will burst/open causing a liftoff of the rocket 28.
Accordingly, one example of a sequence of prelaunch activities includes the user first moving the arm toggle switch 42 on the controller 26 from the disable position to the enable position. At any time after the arm toggle switch 42 is moved to the enable position the launch button 44 may be depressed to initiate a launch. Prior to the arm toggle switch 42 being moved to the enable position (i.e., when the arm toggle switch 42 is in the disable position) the launch button 44 is inactive. In one embodiment, a light in the launch button 44 may illuminate when the arm toggle switch 42 is in the enable position to alert the user that a launch may be conducted. Additionally, after the launch button 44 is depressed the arm toggle switch 42 will return to the disable position.
Once the system is enabled via the arm toggle switch 42 and the launch button 44 is depressed, prelaunch activities that result in a launch of the rocket 28 will occur. For example, the pressurizer 16 will begin filling the air chamber 20 with compressed air 30 as shown in
In an alternate embodiment, not shown, the launcher 14 may transition from a horizontal position to a vertical launch position. The transition of the launcher 14 from the rest position to the launch position may occur manually by the user prior to initiating a launch, or it may occur automatically after the user moves the arm toggle switch 42 from the disable position to the enable position.

Preferably, the parachute 58 is deployed just after the rocket 28 reaches its apex of flight. The rocket 28 may have a sensor (not shown), such as a pressure sensor or a tilt sensor, so that the rocket 28 knows when to deploy the parachute 58. In one embodiment, when a pressure sensor is utilized the pressure sensor is able to sense when the rocket height has decreased a certain distance, such as, for example, three feet, and the sensor will then send a signal to a solenoid (not shown) to deploy the parachute 58. In an alternate embodiment, a mechanical counterweight system may be utilized to determine proper deployment time for the parachute 58. By utilizing a parachute 58, a slower and more controlled descent of the rocket 28 may occur.

In one embodiment, the rocket launching system 110 includes a gearbox 142 and a gearbox motor 158 to assist in fluidly connecting the pressurized gas container 150 with the pressure chamber 126 of the launching base 114. In one embodiment the gearbox 142 and a gearbox motor 158 assist in rotating the cartridge carrier 146 and the attached pressurized gas container 150 relative to the launching base 114, as best shown in
A portion of the pressurized gas container 150 contacts the O-ring 134 before the portion of the pressurized gas container 150 contacts the vented pin 130, as shown in
Following contact between the pressurized gas container 150 and the O-ring 134, the cartridge carrier 146 and the attached pressurized gas container 150 continue to rotate and translate such that the pressurized gas container 150 is contacted, and pierced, by the vented pin 130 in the second position. Compressed gas formerly stored in the pressurized gas container 150 travels into the pressure chamber 126 through vents in the vented pin 130, as indicated in
As pressure increases in the pressure chamber 126 from the piercing of the pressurized gas container 150, a burst membrane 122 maintains a pressure-tight seal. However, upon the pressure chamber 126 reaching a certain threshold pressure, and the burst membrane 122 experiencing the same threshold pressure, the burst membrane 122 ruptures, as best shown in
Following the launch of a rocket 170 as described above, the gearbox motor 158 is operated in a reversed direction, causing the cartridge carrier 146 and attached pressurized gas container 150 to rotate and translate upwardly and away from the O-ring 134 and vented pin 130 due to the threaded connection between the threaded male post 138 and the cartridge carrier 146. The pressurized gas container 150 is then removed from the cartridge carrier 146 and a new, and sealed, pressurized gas container 150 can be connected to the cartridge carrier 146 in preparation for another rocket 170 launch. It is to be understood that the launch tube 118 can be affixed to, or located remotely from, the launching base 114.
Some implementations of the launching base 114 include a plurality of folding covers (not shown) that enclose the rocket 170 mounted on the launch tube 118 when the folding covers are arranged in an upright position. The folding covers may be adjustable downwardly to a launch position. In the launch position, the folding covers no longer enclose the rocket and allow the rocket to launch from the launch tube. The folding covers may also stabilize the launching base on a ground surface when arranged in the launch position. In some implementations the folding covers are manually adjustable between upright and launch positions, while in other implementations the folding covers are electrically adjustable between upright and launch positions by electric motors (not shown). Further, the folding covers may be remotely adjustable between upright and locked positions by a controller, which will be described below in detail.
During a rocket 170 flight, the drone 180 separates from the fuselage 190 in some implementations of the present disclosure, as shown in
Turning to
In some implementations, a streamer (not shown) may be connected to the fuselage 190. The streamer may be loosely engaged with a portion of the drone 180 such that the separation of the drone 180 and the fuselage 190 results in the streamer being deployed from the fuselage 190 after drone 180 separation. The streamer, which may be highly visible with various colors, lights or reflective properties, helps slow the fuselage's descent to the ground after separation with the drone and also aids in visual tracking of the descending fuselage. In some implementations, a parachute or rigid aerodynamic surfaces can be used to slow the descent of the fuselage. In some implementations, the fuselage simply descends to the ground without aerodynamic assistance. The fuselage may include foam or other resilient surfaces to preserve the structural integrity of the fuselage upon contact with a ground surface.
A controller 26 is shown in
The controller 26 may include an LCD screen 198 for displaying various rocket 170, launching base 114 and drone 180 information. In particular, data gathered from the aforementioned sensors and components of the control system 189 can be displayed on the LCD screen 198. A first control 42, or an arming control, initiates a pre-launch sequence. Such a sequence can include audible sounds, such as rocket sounds or a numerical countdown, produced by the controller 26, rocket 170 and/or launching base 114. The pre-launch sequence can also include the operation of various lights on the controller 26, rocket 170 and/or launching base 114. The launching base 114 and/or rocket 170 can also generate a visible gas, or fog, during the pre-launch sequence by vaporizing fluids, such as fog juice.
A second control 44, which may be operable only after the pre-launch sequence, initiates the rocket 170 launch using the pressurized gas container 150, as described above. Following the rocket 170 launch, the drone 180 is remotely operable by the user. In particular, drone controls 199 are used to wirelessly control flight operations of the drone 180. In some implementations, the drone controls 199 can control pitch, roll, yaw, trim, altitude and speed characteristics of the flying drone 180. The drone 180 may also include an autonomous mode that automatically brings the drone 180 into contact with the ground surface. Such a mode may be activated by a loss of wireless signal between the controller 26 and the drone 180. The controller 26 may also remotely adjust the folding covers between upright and locked positions.
Further, the controller 26 can include multiple levels of user control. Such an implementation allows users of various ages or abilities to control various aspects of the rocket launching system 110. In particular, three levels of user control could be selectable by a user. A first mode may include automatic drone 180 separation from the fuselage 190 based on sensors of the control system 189, and the drone 180 automatically returns to the launching base 114 or landing pad. A second mode may include automatic drone 180 separation based on sensors of the control system 189 while the user controls drone 180 thrust and direction to land the drone 180 in conjunction with auto-stabilizing drone 180 software. A third mode may include drone 180 separation induced by a user control and complete, or partially-assisted from auto-stabilizing software, user control of drone 180 flight following separation.

The rocket launching system 210 is preferably energized by pressurized gas. In one embodiment, a pressurized gas container 228, which may be a Carbon Dioxide cartridge, is releasably connected to the cartridge carrier 214. The pressurized gas container 228 may be threadably connected to the cartridge carrier 214. As shown in
In one embodiment, the rocket launching system 210 includes a launch tower 220 having a launch hammer 230, a loading lever 232, a trigger 234, and a solenoid 236. The solenoid 236 is powered by a battery 238 located in the battery chamber 240 of the launch tower 220. The launch hammer 230 is spring biased with a compression launch spring 242 to transmit the launch hammer 230 against the pressurized gas container 228 during the launch sequence. Similarly, the trigger 234 is spring biased with an extension spring 244 to retain the launch hammer 230 against the force of the solenoid 236. In one embodiment the launch hammer is referred to as the carrier transfer mechanism because it transitions the carrier from the carrier first position to the carrier second position.
The rocket launching system 210 also includes a launch controller 26, one example of which is shown in
To operate the rocket launching system 210 a burst membrane 222 is placed in the launch receiver 248 to cover an opening 250 in the launch base 212. This opening 250 in the launch base 212 is typically referred to as the outlet 250 to the pressure chamber 216. Next, the launch tube 224 is connected to the receiver 248 of the launch base 212, with the burst membrane 222 closing the opening 250 from the pressure chamber 216 of the launch base 212 to the launch tube 224. In one embodiment, the launch tube 224 has a threaded member 252 that threads into the launch receiver 248 of the launch base 212. The launch tube 224 is therefore preferably connected to the launch base 212 adjacent the outlet 250 of the pressure chamber 216. In one embodiment, the pressure chamber 216 comprises a cavity 216 within the launch base 212, and the launch base 212 is comprised of a lower housing 254 and an upper housing 256 connected to the lower housing 254.
Next, the launch hammer 230 is set. As shown in
As shown in
When the launch tower 220 is tilted backwards, one end of the loading lever 232 slides in a slide track 276 in the launch tower 220 and the end of the loading lever 232 will engage the launch hammer 230. The launch hammer 230 is slidingly connected to the launch tower 220 and is able to slide about a longitudinal axis of the launch tower 220. The compression launch spring 242 biases the launch hammer 230 toward the base of the launch tower 220 (i.e., toward the cartridge carrier 214). As shown in
When the launch tower 220 is tilted backwards (the first position of the launch tower 22) the user has access to remove an old/used pressurized gas container 228 and insert a new gas container 228 to prepare for another launch of the rocket 226. The pressurized gas container 228 is connected to the rocket launching system 210 via the cartridge carrier 214. Typically, the pressurized gas container 228 is connected to the cartridge carrier 214 via a threading engagement, however alternate mating methods such as via a bayonet connection, a luer lock connection or via other connection means. Access to the cartridge carrier 214 is provided via a cutout 278 in the launch tower 220. The cutout 278 is preferably sized such that only an appropriately sized gas container 228 may be utilized with the rocket launching system 210, as shown in
When the cartridge carrier 214 is accessible for removal/insertion of the gas cartridge 228 as shown in
Accordingly, once an appropriately sized gas container 228 is connected to the cartridge carrier 214 as shown in
Additionally, as seen in
As shown in
To initiate a launch of the rocket 226, in one embodiment a signal must be provided, such as a signal to the solenoid 236 or some other mechanical means, to initiate a launch by moving the trigger 234. The signal is preferably provided by the launch controller 26, either wirelessly or via wired connection. Once the launch signal is provided to the solenoid 236, the solenoid 236 moves the trigger 234 to disengage the trigger 234 from the launch hammer 230. In an alternate embodiment, no solenoid 236 is used and a simple mechanical mechanism, such as a wire or spring, transitions the trigger 234 to release the launch hammer 230. Once the trigger 234 is moved this allows the launch spring 242 to propel the launch hammer 230 toward the gas container 228 connected to the cartridge carrier 214. The launch hammer 230 contacts the gas container 228 and forces the cartridge carrier 214, with the gas container 228 connected thereto, sufficiently downwardly into the pressure chamber 216 of the launch base 212, overcoming the force of the compression spring 268 within the pressure chamber 216. The vent pin 218 pierces the end of the gas container 228 causing the compressed gas formerly stored in the pressurized gas container 228 to travel into the pressure chamber 216, possibly including through vents in a hollow vent pin 218. Because the opening 274 in the upper housing 256 of the launch base 212 is sealed to the cartridge carrier 214 with the O-ring 272, the compressed gas formerly stored in the pressurized gas container 228 travels only into the pressure chamber 216. Accordingly, an internal pressure rises in the pressure chamber 216 following the piercing of the pressurized gas container 228. As is understood, the carrier 214 is for supporting a pressurized gas container 228, and the carrier moves from a first position (see
As pressure increases in the pressure chamber 216 from the piercing of the pressurized gas container 228, the burst membrane 222 maintains a pressure-tight seal at the only other opening in the pressure chamber 216 at the launch receiver 248 portion of the launch base 212. Preferably, when the pressure chamber 216 reaches a certain threshold pressure the burst membrane 222 will rupture allowing the pressurized gas in the pressure chamber 216 to pass through the ruptured burst membrane 222 and enter the launch tube 224, providing a sufficient force to launch the rocket 226 from the launch tube 224.
In one embodiment, immediately following the release of the pressurized gas from the gas container 228 into the pressure chamber 216 and prior to the launch of the rocket 226, the combination of the gas pressure in the pressure chamber 216 in addition to the spring pressure of the compression spring 268 on the cartridge carrier 214 within the pressure chamber 216, will cause the cartridge carrier 214 to be raised slightly. As the cartridge carrier 214 is raised out of the pressure chamber 216 slightly the shaft 262 of the cartridge carrier 214, which also is present in an internal cam track 282 in the sidewall of the launch tower 220, as shown in
If, however, the burst membrane 222 does rupture and the pressure chamber 216 is retained at high pressure, the rocket launching system 210 has a means for safely releasing the pressurized gas from the pressure chamber 216. In one embodiment, the user can release the pressure from the pressure chamber 216 by tilting the launch tower 220 away from the launch tube 224 and rocket 226. When the launch tower 220 is pivoted backwards the cam surface 266 of the launch tower 220 will lift the cartridge carrier 214 back out of the pressure chamber 216 due to the engagement of the cam surface 266 of the launch tower 220 with the shoulder 264 of the cartridge carrier 214. When the launch tower 220 is tilted sufficiently backwards, such as shown in
Following the launch of a rocket 226 as described above, the launch tower 220 can be pivoted away from the launch tube 224 as explained above and shown in
As shown in
Another embodiment of the rocket 226 is shown in
The drone features may include a plurality of propellers 293 powered by one or more propulsion motors 294. The propellers 293 and propulsion motors 294 are attached to the rocket body 284 by arms 295. In one embodiment a slidable collar 296 is connected around the rocket body 284 and the arms 295 are connected to the slidable collar 296. Pivot arms 297 are also provided and connect between the arms 295 and a lower fixed collar 298. The combination of the slidable collar 296, arms 295, pivot arms 297 and fixed collar 298 forms a three-bar mechanism that allows the drone features to transition from the collapsed state, as shown in
One embodiment of the controller 26 is shown in
A second control 44 which may be operable only after the pre-launch sequence, initiates the rocket 226 launch using the pressurized gas container 228, as described above. Following the rocket launch, the propellers 293 are controllable by the user. In particular, drone-style controls 199 are used to wirelessly control flight operations of the propellers of the rocket. In some implementations, the drone-style controls 199 can control pitch, roll, yaw, trim, altitude and speed characteristics of the propellers. The rocket with propellers may also include an autonomous mode that automatically brings the rocket into contact with the ground surface. Such a mode may be activated by a loss of wireless signal between the controller 26 and the rocket 226.
