Field
The present invention relates to a system to mechanically assist with opening a parafoil. More specifically, the present invention is related to assisting in the opening of a parafoil transitioning from a state where it is not flying to a state where it is flying, especially when that system is starting with little to no airspeed, starting in low density air, or both. Mechanically aiding in the opening of a parachute allows parafoils to inflate and fly in environments where they otherwise may not have been capable of opening and transitioning to flight reliably. Avoiding entanglement is also important during the period of low air speeds, in low density air (such as at high altitudes), or both, where there is no force of wind to hold the parachute fabric away from the payload and from entangling with itself. Thus embodiments of the present invention preferably serve a dual purpose both as a mechanism to assist in the opening of the parafoil envelope and as an anti-entanglement device holding the fabric, lines and payload away from each other so they cannot snag or tangle
Description of the Related Art
Note that the following discussion may refer to a number of publications and references. Discussion of such publications herein is given for more complete background of the scientific principles and is not to be construed as an admission that such publications are prior art for patentability determination purposes.
The word parafoil is, appropriately, the combination of the words “parachute” and “airfoil”. A parafoil is essentially an inflatable wing combining the light weight and packability of a parachute with the cross-range, steerability and landability of an airfoil. A parafoil is often referred to as a parachute or a ram air parachute, and may be referred to as such herein. Parafoils comprise a fabric canopy and parachute lines. Parafoils have a much more complex opening and inflation dynamic than round parachutes do. Because the wing is typically inflated from the leading edge the inflation process happens in multiple stages. This opening dynamic is problematic at high altitudes. Because the air at high altitudes is thin, and the inflation ports of the canopy do not necessarily face the airstream, there is substantial risk when using parafoils at high altitude that they will fail to inflate for too long a period. At this point, once the canopy orients and finally does inflate, the airspeeds may be too high and the opening could destroy the parafoil or whatever is beneath it.
The present invention is a method of opening a parafoil comprising a canopy and a plurality of flexible members, the method comprising deforming the flexible members, thereby storing elastic potential energy in the flexible members, wherein a top end of each flexible member is connected to the parafoil canopy; securing the parafoil canopy and the deformed flexible members in a stowed configuration; attaching the parafoil to a flight vehicle; detaching the parafoil from the flight vehicle; releasing the parafoil canopy and the flexible members; and the flexible members returning to their undeformed shape, thereby at least partially deploying the parafoil canopy. The base end of each flexible member is preferably connected to a base member, optionally via a hinge, with the base member connected to a payload. The method optionally comprises one or more suspension lines, but not all suspension lines, supporting the weight of the payload during flight of the flight vehicle, the suspension lines connecting the base member and the canopy. The deforming step preferably comprises bringing the top ends of the flexible members together, the flexible members bending around a plate or fulcrum disposed between the top ends and the base ends. After the releasing step, the flexible members preferably spread apart from each other past a vertical orientation, at which point gravity preferably continues to spread apart the flexible members until the parafoil canopy is completely deployed. The deforming step preferably comprises folding the parafoil canopy and the securing step comprises disposing the folded parafoil canopy in a parachute bag. The detaching and releasing steps are optionally performed at an altitude greater than approximately 25,000 feet, or greater than approximately 50,000 feet. The releasing step is optionally performed before or approximately simultaneously with the detaching step.
The present invention is also a parafoil comprising a canopy; a base member connected to the canopy via a plurality of suspension lines; and a plurality of flexible members attached to the canopy. The flexible members are preferably attached to the base member, optionally via a hinge. The base member optionally comprises a fulcrum for bending each flexible member; alternatively, the parafoil comprises a plate disposed between the base member and the canopy for bending the flexible members. Each flexible member optionally comprises a hollow tube, in which case each flexible member optionally comprises a telescoping end attached to the canopy or a suspension line disposed within each flexible member.
Objects, advantages and novel features, and further scope of applicability of the present invention will be set forth in part in the detailed description to follow, taken in conjunction with the accompanying drawings, and in part will become apparent to those skilled in the art upon examination of the following, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims
The accompanying drawings, which are incorporated into and form a part of the specification, illustrate the practice of embodiments of the present invention and, together with the description, serve to explain the principles of the invention. The drawings are only for the purpose of illustrating certain embodiments of the invention and are not to be construed as limiting the invention. In the figures:
The present invention pertains to the assisting in the opening of a parafoil either during or prior to separating from a supporting structure while in low density air, starting with little air speed, or both. Embodiments of the present invention use stored energy to assist in the opening of a parafoil. Some embodiments of the present invention include spring loaded rods pushing open the parafoil envelope, hinged rods that use potential energy of their weight in a stowed configuration to open a parafoil, or rods that use a combination of stored potential energy and spring energy to open a parafoil envelope. Other embodiments of the present invention include utilizing inflatable bladders to spread the parafoil envelope, inflating the parafoil directly with compressors or compressed gas, using the weight of the mass suspended beneath the parafoil to force a mechanical arm to open the parafoil, using thruster mechanisms to push the envelope open, using springs to open the bottom of the parafoil envelope or using deployable split-tube booms to assist in the opening of the canopy. One embodiment of the present invention utilizes flexible rods connected to a base structure with hinges to assist in opening a parafoil. The rods can be flexed using a fulcrum near the base structure to a central point where they are preferably restrained at the base of the packed parafoil. When released the rods preferably spring out and fall away from the central structure, optionally assisted by gravity, opening the parafoil envelope prior to, during, or after the release of the parafoil from the supporting structure. This embodiment can be operated using flexed rods acting like springs, hinged rods assisted by gravity, or preferably, a combination of both.
An embodiment of the present invention utilizes hinged flexible poles connected to a rigid base both supporting the poles and providing an attachment platform between a payload and a mechanism to lift the payload, such as a high altitude balloon. This embodiment is particularly useful for use with payloads having a mass greater than approximately 2,000 lbs., although it may be used with any payload. As shown in
Base 120 of each wing tip support is preferably fastened to main structural beam 116 via hinge bracket 114, a detail of which is shown in
The top of the wing tip support preferably comprises a pole that is allowed to translate along the axis of wing tip support in a linear fashion as shown in
The packed configuration of the parafoil can be seen in
When the stowed system shown in
In another embodiment of the invention, the parafoil is predeployed or otherwise assisted in opening using flexed rods on hinged bases, similar to the previous embodiment. In this embodiment of the invention the wing tip supports are held by retention cords while stowed, instead of flexed around a fulcrum. This embodiment of the invention is suitable for, but not limited to, payload masses between approximately 500 and 2000 lbs. In this embodiment of the invention payload 200 can be functionally recovered from a starting condition where the system has little starting airspeed or is in low density air.
The system starts in a packed configuration as shown in
A detailed view of the attachment of wing tip supports 216 to parachute deployment bag 215 is shown in
A detailed view of riser bracket 220 can be seen in
Once flying the system is preferably suspended under the parafoil as shown in
Rings 202 are for attaching the parafoil to the base of the balloon during ascent. This transfers the load due to the payload through suspension lines 223 to the flight vehicle, such as a high altitude balloon. For predeploy, the parachute deployment bag can be opened by severing a loop that holds both the bag closed and the wing tip supports under stress due to their bending, allowing the parachute to spring open before the release of rings 202 from the balloon. The parafoil is then released from the balloon by the release of rings 202. Alternatively, the parachute bag can be opened at approximately the same time as the release of rings 202 from the balloon.
Another embodiment of the invention that allows a system to begin flight under a parafoil in situations where the system has little air speed, is in low density air, or both. This embodiment of the invention is suitable for, but not limited to, payloads having a mass less than approximately 500 lbs. In this embodiment of the invention select parachute suspension lines are rigidized (but still flexible) and flexed around a spreading plate to provide opening force. This embodiment of the invention does not comprise hinges or wing tip supports because the rigidized suspension lines are responsible for spreading the canopy.
A detail of the deployment bag and attachment structure at the top of the system is shown in
The system is preferably released using a remote signal which activates a release mechanism that opens a deployment bag 309. Once released the system will begin to fall and the tensioned, rigidized suspension lines 310 pull the parafoil open, assisting in the parafoil deployment. Shortly after releasing a combination of the airflow and the rigidized suspension lines will open parafoil canopy 300 to a state where it is flying, as shown in
In any of the previous embodiments, once the wing tip supports (or rigidized lines) spring open and outward past vertical, the force of gravity can assist with them continuing to spread apart until the parafoil canopy is completely deployed.
