Abstract: 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.

Abstract: An aerial vehicle safety apparatus includes an expandable object and an ejection apparatus. The ejection apparatus includes a container that accommodates the expandable object and has an opening provided on one end side, a moving member provided in the container, the moving member including an emission base carrying the expandable object on a side of the opening, the moving member being movable along an inner wall of the container, and a driver that ejects the expandable object by moving the moving member toward the opening. A space located opposite to the opening when viewed from the emission base and surrounded by the container and the moving member communicates with a space located outside the space through a communication portion.

Abstract: Disclosed is a personal flying machine using compressed air as power source, and an operation method thereof, the flying machine including a stationary rotor lift device in a cyclone duct, a seat frame and a compressed air supply device; wherein the stationary rotor lift device in a cyclone duct includes a cyclone duct, in-duct stationary rotors and in-duct compressed air artificial wind blowing ports; wherein the in-duct stationary rotor includes a stationary propeller hub and a plurality of stationary blades fixed connected around the stationary propeller hub and arranged radially; wherein the stationary blade is shaped as an airplane's wing having an airfoil, an angle of attack, a leading edge and a trailing edge; wherein the compressed-air supply device supplies compressed air to the in-duct compressed-air artificial wind blowing ports to eject airflows towards the leading edges of the stationary blades and form a cyclone to generate lift. The present application solves the problems of efficiency limitation, high cost, heavy structure and energy-environment issues related to the traditional personal flying machines of burning fossil fuels to do work, and overcomes their shortcomings and problems with the wingless or wing-movement to generate lift in relatively static air.

Abstract: An aircraft, the aircraft including a whole-aircraft ballistic parachute that is coupled to the aircraft. The aircraft determines if a pre-activation action needs to be performed before activation of the whole-aircraft ballistic parachute. The aircraft also receives a whole-aircraft ballistic parachute activation request. The aircraft then issues a command to perform the pre-activation action and then activates the deployment of the whole-aircraft ballistic parachute. The aircraft then issues a command to perform a post-activation action.

Abstract: 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.
