摘要： A parafoil for operation at high altitudes, in low density air, or at low airspeeds, and methods for opening same. Some versions of the parafoil comprise members connected to the parafoil canopy. When the parafoil canopy is in a stowed configuration, the members are constrained. When the canopy is released from its stowed configuration, the members open or assist with opening the canopy. The members may also be attached to a base structure, which is attached to the payload. The members may comprise rods or hollow tubes and use a fulcrum near the base structure, or a spacer plate. The ends connected to the canopy may be restrained by a parachute bag containing the stowed or packed canopy. The parachute bag can be opened prior to or during detachment of the parafoil from the flight vehicle.

摘要： Disclosed herein are parachute canopies and sliders for use with parachutes. The parachute canopies can include one or more deformable vent panels that can be used to control an inflation rate of the canopies based on an internal pressure within the canopies. The sliders can include strips that form through holes that have a width that distributes a radial load on suspension lines and allow for the use of lower weight, high modulus suspension lines.

摘要： A variable-geometry vertical takeoff and landing (VTOL) aircraft system may transport passengers from a departure point to a destination via partially or fully autonomous flight operations. The VTOL aircraft system may operate in hover-based ascent/descent modes, level-flight cruising modes, and transitional modes between the two. Thrust may be provided by ducted propeller units articulable relative to the fuselage; by articulating the airfoil struts connecting the thrust sources to the fuselage the thrust sources may be manipulated for ascent/descent, transition, and cruising. in order to control ascent, descent, and cruise. More precise thrust control may be achieved by further articulation of the annular propeller ducts relative to the airfoil struts. The airfoil struts and propeller ducts may present a wing-shaped or variably segmented cross section to maximize achievable lift.

摘要： A paradrone includes a canopy having a parafoil, a transverse canopy frame coupled to the parafoil to support the parafoil, a longitudinal canopy frame that is coupled to the parafoil while having a bent structure such that the parafoil generates a lift, and at least one parafoil connecting portion for connecting at least one canopy frame among the transverse canopy frame and the longitudinal canopy frame to the parafoil. The paradrone also includes a servomotor portion having a servomotor body and a servomotor arm for coupling and fixing intersecting parts of the transverse canopy frame and the longitudinal canopy frame. The servomotor arm is connected to a servomotor body and rotated in a predetermined direction by driving of the servomotor body to change the angle between the travelling direction of the paradrone fuselage and the transverse and longitudinal canopy frames, thereby changing the angle of attack.

摘要： A riser release system controllably lands a descending flight vehicle having a parafoil or canopy. The system has control lines and riser lines attached to the parafoil or canopy. The other end of the riser lines are attached to an upper portion of a release structure; a lower portion of the release structure is connected to the payload; and a coupling mechanisms releasably couples the upper and lower portions. When the upper and lower portions are decoupled, a distance control device controls and limits the distance of separation between the two portions, and a rate control device controls the rate of separation. Separation causes the riser lines to increase the distance between the payload and canopy, further causing the canopy to flare and decrease the rate of descent of the flight vehicle.

摘要： Described herein are features for a riser release flaring system for parafoils and other descent flight vehicles for controlled descent and landing of the flight vehicle. The descent flight vehicle may have a payload suspended by a canopy. The descent flight vehicle may be released from a high altitude lighter-than-air (LTA) system, from another system, or may not be associated with any other flight system. The riser release auto flare system is used with the descent system, such as the parafoil, for controlled and safe landing of the payload. Riser lines are released at a controlled rate and for a fixed distance to automatically cause the payload to pull control lines to flare the parafoil and slow a descent and/or forward speed of the vehicle. The riser lines may be released in response to the descent system satisfying a landing criterion, such as altitude.

摘要： A parafoil system having an adjustable trim angle during flight to control glide slope and descent speed of a parafoil is provided. The parafoil system may include a pulley cluster comprising first and second variable trim pulleys, each having a different diameter. The pulley cluster may be coupled to forward and aft suspension lines of a parafoil canopy such that the pulley cluster may rotate to retract or extend the forward and aft suspension lines to adjust the trim angle during flight. The parafoil system may further include a motor for rotating the pulley cluster to extend or retract the suspension lines to adjust the trim angle during flight. By adjusting the trim angle of the canopy during flight, the glide slope and descent speed of the parafoil system may be controlled.
