This invention relates to a Special electric propulsion system called a CanopE-Jet to power paragliders and other small, light aircraft. Particularly this relates to an apparatus and system for paragliders. As an improved means of propulsion for use by an individual when engaging in paragliding, powered paragliding, paramotoring, hang gliding, and other similar sporting activities. This relates to propulsion arrangements which can be secured to the pilot or seat for a pilot, and which gives the pilot controllable powered flight.
This is a personal air propulsion device for use by an individual and potential passenger. This could be used with snow skiing, skating, bicycling, or so-called “extreme sports” including skateboarding, snowboarding, surfing, power kiting and the like. The system relates, in general, to the use of single or clustered, high RPM electric ducted fans employing the Coanda effect to provide thrust for transportation systems and enabling component designs for vehicles such as ultralight aircraft, and, more particularly, to a flying entertainment vehicle. This invention relates to such devices that provide for hands-free operation and control of the device and are configured to accept adjustments for versatility. The multiple electric thrusters’ ducted fans can be made of carbon fiber for light weight and strength but can also be fabricated from a variety of other materials and the CanopE-Jet can fly for several minutes per charge, depending on the number of batteries and energy density of the batteries being carried.

As far as known, there are no Special electric jet propulsion systems to power paragliders and other small, light aircraft or the like. It is believed that this product is unique in its design and technologies.
Personal flight devices were developed in the 1960s and 1970s but were essentially rocket based devices (jet belts) which gave extremely short flight times (typically about 26 seconds) and were difficult to control. Further, these devices were fueled by rocket fuel which is intrinsically dangerous. More recently, a number of personal flight devices have been proposed which use ducted fans as their means of propulsion: — for example, a device which includes a pair of ducted fans, and which is steered by tilting the ducted fans relative to the pilot. A broadly similar type of design has been proposed, using shrouded propellers rather than ducted fans. Additionally, powered paragliders have been in production and use since the 1970s and 1980s using gas powered, propeller-driven systems. In the 2000s and 2010s, electric, propeller-driven systems have come into use, using single or multiple open propellers but still using a protective “loop” cage to prevent paraglider lines from entering the propeller.
A personal air propulsion device of sophisticated design is needed to power an individual over a chosen surface. The surface might be ice, snow, water, land, pavement, or any surface chosen. The device should provide lightweight air propulsion from an internal combustion engine powering a fan. Air should be expelled from the device in a way that further increases thrust. Until now, individual jet flight devices have been produced, but they have the disadvantage of being able to fly only a few minutes because they consume a large amount of fuel, which limits flight endurance and performance.
Paragliding equipment in general is well known and generally includes a harness section that a user secures to his body with loops and restraints to enable the user to be comfortably suspended in flight and move relatively freely, and a wing section (canopy) of fabric designed to act as an airfoil for slowing the rate of fall of a user and for capturing lift from thermal air movement. In use, the user is suspended below the canopy via suspension wires. Powered paragliding or paramotoring is also known, in which a paraglider mounts an engine or electric power source to his or her back to add power to the paragliding activity. Modern powered paramotoring gives pilots the ability to soar and stay airborne for hours using only rising air currents. Existing arrangements, however, suffer limitations on different aspects and create additional challenges for both the designers and the pilots. For instance, the added weight of some of these arrangements can require additional efforts from the pilot during takeoff, landing and in flight. It can also reduce the easiness of maneuvering the unit compared to an unpowered version. Still, the added weight can significantly modify the location of the center of gravity of the unit compared to the original powerless version. In some cases, redesigning the original paraglider may be necessary before providing it with a motor. Room for improvements always exists in this area of technology.
Present designs are either too small and underpowered to be used as a Personal Air Propulsion System, herein referred to as PAPS, or to bulky requiring far too big of a device to be convenient in most applications. Based on the foregoing, there is a need in the art for a lightweight design of a ducted fan propulsion which may be utilized in a wide range of applications.
New developments in small lightweight electric motors have focused on a system that is a ducted fans system for powering small ground vehicles the system is also applicable to aircraft, ground effect vehicles, manned or unmanned drones, water-based vehicles or personnel systems that require no vehicle at all. While current electric motors have very high power to weight ratios the associated power supplies, batteries and/or generators are much heavier and bulkier. Also, current propeller and ducted fan systems are fragile and potentially dangerous. This system is applicable whether the fan is used to provide propulsive thrust or vertical lift. A need exists for a lightweight, high thrust, zero emissions alternative transportation device that is safe from exposed propeller.
The improvement and problem solved as to Special electric propulsion system to power paragliders and other small, light aircraft includes: a lighter weight due to lighter electric motors than gas-powered systems; no fuel or Greenhouse Gas (GHG) emissions since it is all electric, battery powered; it has a small footprint and be transported in a standard car seat, trunk, or rear of an SUV; the craft has rapid setup for launch and rapid start and can result in faster potential airspeed, limited only by the speed limitation of the wing/paraglider, with potential, theoretical speeds of over 300 mph; has a smooth, low-vibration operation; uses ducted turbines with protected intakes and more than one ducted fan/turbine arrayed with counter-rotating propellers/turbines; and is a safer system with no exposed propeller blades which often can damage paraglider lines and other objects.

The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate an embodiment of the Special electric propulsion system 30 to power paragliders and other small, light aircraft that is preferred. The drawings together with the summary description given above and a detailed description given below explain the principles of the Special electric propulsion system 30. It is understood, however, that system 30 is not limited to only the precise arrangements and instrumentalities shown. Other examples of propulsion systems for small aircraft are still understood by one skilled in the art of this industry to be within the scope and spirit shown here.
This invention uses electric “jets”, or ducted fans using a Coanda effect to accelerate air through a shaped duct, in order to amplify thrust, reduce power usage, and/or increase the performance of the propulsion system - all WITHOUT the need for a protective propeller ring as the ducted turbines or propellers would be inaccessible to the paraglider lines. Note: The Coandă effect is the tendency of a jet of fluid emerging from an orifice to follow an adjacent flat or curved surface and to entrain fluid from the surroundings so that a region of lower pressure develops. The Romanian inventor Henri Coandă, was the first to described it as “the tendency of a jet of fluid emerging from an orifice to follow an adjacent flat or curved surface and to entrain fluid from the surroundings so that a region of lower pressure develops″. Coandă was the first to recognize the practical application of the phenomenon in aircraft design.
The anticipated materials for the small aircraft propulsion system 30 called CanopE Jet include: a group of fabric material for the safety belts 65, 66 and harnesses 91 can be nylon, rayon, cotton, polyester, leathers, vinyl, and synthetic or non-synthetic composite materials. The characteristics preferred are: a fabric which is flexible, comfortable, strong, cut-resistant, lightweight, and easy to clean. The method to attach 67 the belts and harnesses to the frame 71 or to each other may be sewing, clips, rivets, or various fasteners. The frame structures 70, 71 may be of a variety of configurations. For example, and not as a limitation, the structures may be tubular (round, oval, square, rectangular, or other regular or non-regular polygonal cross-sections); the structures may be angles, Zees, Tees, “I” or wide flange (“W” or “H”) or other cross-sections not specifically identified. The materials for example and not limitation may be a metal like steel, a steel alloy, aluminum, titanium, a composite plastic or any other light weight, durable material. The propellers 51 may be a metal such as steel, steel alloy, aluminum, titanium; a composite material; a wood laminate, or other durable, light weight yet sufficiently sturdy material. Propellers are well known in the art of aircraft and may be selected from a plethora of styles and materials. The other components are likewise expected to be of lightweight, strong, and durable materials shaped to appropriate configurations. However, these are exemplary and lot limitations to other means which are well within the spirit and scope of the full embodiment of system 30.
The entire propeller driven system, as just described, rotates around the fixed shaft which can have an aperture (hollow opening) throughout its center. The various control wiring is often guided along and through the structure as is well known in the art of lightweight aircraft. Also, a mount for the motor(s) 78 are normally retained by a collar to the shaft. The battery (ies) 74 are connected through cables 76 to the motor(s). The electric power from the battery powers the motor which transforms the stored electrical energy into kinetic energy and rotational power. This power is further transferred to the propellers and the system shown or a functional equivalent. The motors 78 have relatively simple controls 80 as one skilled in the art of electromechanical power systems well appreciates. An optional remote-control system may be employed for using the system 30 as drone, non-human pilot-controlled aircraft if desired. This remote system is also well known to those skilled in the art of electrical and electronic remote-control systems. This remote control operation could be used to group multiple units together and control from a central system. Thereby, several propulsion systems could be embodied as a cluster and then attached to a larger payload and/ or larger canope/ paraglider wing 120, 120A. Multiple units of the special Electric Propulsion System 30 to power paragliders 120 and other aircraft called a CanopE-JET are configured together to enable clusters. A Structural connection 38 is attached between Electric Propulsion System 30 is removably attached with straps to make a 4, 8, or multiple cluster systems of the propulsion system for larger payloads and for larger canopes. The structural connection 38 attached with straps, simple fasteners, cords and the like to enable cluster systems - 4 fan, 8 fan or more systems and the like. See
This system anticipates various types of rechargeable battery 74 back including but not limited to: Nickle Cadmium batteries, Nickle Metal Hydride batteries, Lithium-Ion batteries, Small and sealed lead acid batteries. These may be Absorbed glass mat (AGM) battery or gel battery (“gel cell”). Other experimental types include Lithium sulfur, Sodium-ion, Thin film lithium, Zinc-bromide, Zinc-cerium, Vanadium redox, Sodium-sulfur, Molten salt, and Silver-zinc. One skilled in the art of rechargeable batteries also anticipates and fully expects other battery types to be developed which will function well and be within the scope and breadth of this invention.
The details mentioned here are exemplary and not limiting. Other specific components and manners specific to describing a Special electric propulsion system 30 to power paragliders and other small, light aircraft may be added as a person having ordinary skill in the field of the art of propulsion systems for small aircraft well appreciates.
The Special electric propulsion system 30 to power paragliders and other small, light aircraft has been described in the above embodiment. The manner of how the device operates is described below. One notes well that the description above and the operation described here must be taken together to fully illustrate the concept of the Special electric propulsion system to power paragliders and other small, light aircraft. The preferred embodiment of the special Electric Propulsion System 30 to power paragliders 120 and other aircraft called a CanopE-JET comprised of: (a) a frame system 70, 71, 72; (b) a ducted turbine system comprising at least one turbine 50 with a set of blades or impellers 51 of the fan/turbine 50, a shroud/ exterior protection and frame 55 of the turbine/fan 50, a cut protector 55A on shroud 55, a means 56 to secure shroud 55 and support 59 to seat frame 71, and an electric motor 78 of the Special Electric Propulsion System 30 with shaft 58 connected to blades 51; (c) a seat assembly comprised of a seat 60, an arm rest frame 61, a seat back 62, a structural support 63 on seat 60 and components 64, a set of components 64, a seat belt 65 holds a user 100 to seat 60, a pair of shoulder straps 66 to hold user 100, a means for connecting 67 belt 65 and straps 66 to seat structure 71, a means for connecting 68 seat 60, seat back 62 and arm rests 63 to seat structure 71; (d) a power system comprising a set of rechargeable batteries 74, a set of battery boxes 75, a wiring harness from batteries 74 to motors 78, a means for removably connecting 77 battery box 75 and wiring harness 76 to seat structure 71, a recharge plug 79 to batteries 74 from recharging power source 89, and a recharging power source 89 to utility receptacle, solar panels on airfoil or on ground stand, or wired system generator; (e) a servo-throttle 80 for powering motor of the Special Electric Propulsion System 30 comprising a handle grip 81, a spring switch 82 to throttle/ engage the electric power from battery 75 to motor 78, a wiring cable/conduction/harness 83, a set of connectors 85 from the set of batteries 75 to the motor 78; and (f) a system to attach the frame 71 to an aircraft 120 including a harness 90 from seat assembly to the aircraft 120 such as a paraglider 120A with user/operator 100, a pair of eyelets 91 on the frame 71 for harness 90, and a means 92 for removably securing eyelets 91 to harness 90.
The special Electric Propulsion System 30 functions as follows: The electric fans and motors devices 50, 78 are small, lightweight and may be ducted with carbon-fiber or other lightweight material ducts. Motors are connected to electronic speed controllers and powered by batteries and then managed through a throttle 80, which is managed by a user/operator 100. The throttle balances thrust, and limits roll from side to side. By moving and pulling down on the paraglider toggles attached to the paraglider and the harness 90 connected to points 91 and mounted to the frame 71, craft 120 is controlled and directed. The frame is connected to a harness 90, in which the user 100 sits on the connected seat 60.
An additional tandem seat can be added to carry another person. The throttle 80 is squeezed in order to accelerate the thrust, and then the throttle 80 is released to reduce thrust. At takeoff, a higher throttle settings or full throttle may be required, depending on the head wind, and then lower throttle settings would be used to cruise and/or take advantage of gliding or the use of naturally occurring thermals to gain altitude.
