摘要： An embodiment of the present invention discloses a repair system for a planetary exploration parachute. The repair system includes a folding piece and a fuse, the fuse is provided in the folding piece, a sensing signal for reflecting an impact force of dust is received by the fuse, fusing is generated in the fuse when the sensing signal is greater than a preset threshold, and the folding piece is changed from a folded state to an unfolded state after the fusing is generated in the fuse, so as to automatically repair a damaged part of the parachute.

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 flexible members connected to the parafoil canopy. When the parafoil canopy is in a stowed configuration, the members are deformed, storing elastic energy. When the canopy is released from its stowed configuration, the members spring back to their undeformed shapes, thereby opening or assisting with opening the canopy. The flexible member may also be attached to a base structure, which is attached to the payload. The members may comprise rods or hollow tubes that can be flexed using a fulcrum near the base structure, or a spacer plate, so that the ends connected to the canopy are 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 is an apparatus and method for operating a gliding parachute/kite. The gliding parachute/kite has a wing with a flexible material, and a set of suspension lines adapted for coupling a load to the wing, such that the coupling is configurable in any one of a plurality of possible states based on relative lengths of the suspension lines. In some implementations, the possible states include a first state enabling gliding in a first direction, and a second state enabling gliding in a second direction that is opposite to the first direction. Reversing direction is possible with the first and second states. Additionally, or alternatively, the possible states include a spinning state enabling spinning of the gliding parachute/kite. Adjusting a rate of decent is possible with the spinning. Reversing direction and/or spinning operations can be used to improve control of trajectory.

摘要： The disclosure provides an HAPR apparatus comprising an inflatable frame configured to generate canopy extension based on surrounding atmospheric pressure. The inflatable frame has a first collapse load limit less than the weight of the canopy at a first pressurized state less than 75 kPa and a second collapse load limit greater than the weight of the canopy at a second pressurized state of greater than 95 kPa. The internal pressure of the inflatable frame is typically about 101 kPa. The HAPR apparatus allows ascension with the canopy hanging under its own weight to reduce ascension time, then generates canopy extension prior to release in essentially a zero velocity, zero dynamic pressure condition.

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： Aspects described herein relate to an apparatus, system, and method for the airborne launch of inflatable, lighter-than-air devices from aircraft. In some instances, a container comprising a drag parachute and a main parachute assembly may be deployed from an aircraft. Drag forces on the container may cause the drag parachute to be expelled from the container. Drag forces on the drag parachute may cause the main parachute assembly to be expelled from the container. The main parachute assembly may include a canopy with an opening and a release channel connecting the opening with the container. The container may further include a balloon inflation mechanism, which may be used to inflate one or more balloon envelopes. The one or more balloon envelopes, after being inflated, may be configured to be released from the container, traverse the release channel, and exit the main parachute assembly through the opening.

摘要： The present disclosure provides danger avoidance apparatuses and related methods, such as for use to avoid avalanches. An apparatus may include a container configured to couple to a user, a lift providing mechanism, a descent control mechanism and at least one rip cord engaged with the container and selectively operable by the user. Both the lift providing mechanism and the descent control mechanism may be movably coupled to the container between a packed position within the container and a deployed position exterior to the container controlled via the at least one rip cord. The lift providing mechanism may include an airfoil that provides lift to the user at a first velocity of the user along a first direction. The descent control mechanism may control the descent and reduce the velocity of the user along the first direction from the first velocity in the deployed position.

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.
