A parachute system includes a release that detachably couples a self-propelled projectile and parachute canopy to each other. The release detaches the two from each other in response to a triggering of the release. There is also a first path between the release and a payload where the first path includes the parachute canopy and a suspension line between the parachute canopy and the payload. At least part of the suspension line is bound such that the first path is effectively shorter than a second path. In response to the first path being drawn taut, the suspension line becomes unbound so that the first path becomes effectively longer than the second path. In response to the second path being drawn taut after the suspension line becomes unbound, the release is triggered.

A high-rise building escape apparatus enables user to quickly exit a high-rise building in the event of an emergency. It mainly includes a damper which withstands impact of termination of descent and decreases terminal velocity due to its mushroomlike shape, a compartment, side and bottom nets, a parachute, an air source system, hoses, rotatable and fix frames, and a safety belt. The apparatus is operated following the procedure below. A user sets up the fix frame and rotatable frame attaching the dropping parts on the sill of a window or on the top of a balcony, makes the rotatable frame swing to the outside, opens the dropping part pack, fills the high pressure air to the airbags simultaneously through a number of internal hoses and an external hose, and disconnects the hoses. The user then moves from the inside of the building to the compartment in the middle of the damper through the rotatable frame with hands grabbing it, reaches the bottom portion of the compartment, fastens the safety belt, and releases the dropping parts. As a result, the user will move down with the damper, the parachute will be extended, released, and deployed, and the rotatable frame will rotate back. As soon as the user reaches the ground, the user will unbuckle the safety belt, get out of the damper, and release the high pressure air.

A parachute system includes a parachute which is coupled to a rocket via a first load path, which includes a tow line, one or more upper parachute lines, and one or more lower parachute lines, and a second load path, which includes a release line. The rocket is configured to tow the parachute via the tow line. There is a lower parachute line restrainer which when released permits the lower parachute lines to extend to full length. There is also a release which is configured to open in the event a load switches from the first load path to the second load path; when the release is open, the parachute and the rocket are permitted to separate.

An air delivery barrel system is described, the air delivery barrel system includes a strap system that provides line stretch of the strap system when a force is exerted on the strap system, the strap system including a continuous strap, a first barrel, the first barrel being formed out of a cylindrically shaped wall and the cylindrically shaped wall including a channel that the strap system passes through, an end cap, the end cap being detachably connectable to a bottom end of the first barrel, the end cap protecting a bottom portion of the strap system, a lid, the lid being detachably connectable to a top end of the first barrel, the lid including a recess through which the strap system passes through, and a second barrel that can be situated within the first barrel and the cylindrically shaped wall of the first barrel protects the second barrel.

A system and method is provided for shortening specific suspension lines near the center of a ram air parachute in order to distort the airfoil section only in the center section of the canopy. This distortion of the center section results in a significant alteration of the glide ratio of the parachute by simultaneously reducing the forward speed and increasing the rate of descent. Meanwhile, because the canopy is only distorted in the center section, the wingtips remain extended and pressurized so that the steering apparatus at the trailing edge of the canopy remains fully functional to direct the heading.

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.

A parachute includes a resistive body which is formed in a bag shape and receives air resistance, and two suspension lines, one end of each of which is connected to the resistive body and the other end of each of which can be connected to an object to be braked. The resistive body includes an opening through which air passes, a bottom part provided at an opposite side of the opening, and a side part provided extending toward a periphery of the opening from the bottom part while expanding. The side part includes a base part having an approximately constant height from the bottom part, and two tapered extension parts, each of which extends from the base part, while reducing a width thereof, to each of two ends as apexes located symmetrically with each other in the periphery of the opening.

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.
