Parachute deployment system using decoupled tow and release lines

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.

MECHANICAL TIMING CONNECTION FOR SEQUENCING AIRBAG ACTIVATION WITH ROCKET FOR DEPLOYING AIRCRAFT PARACHUTE

An aircraft includes an airframe parachute system. The parachute system includes an activation system, an extraction system, a harness system, and a parachute assembly.

Impact velocity reduction by mass ejection
09908638 · 2018-03-06 · ·

A ballistic parachute is released to slow descent of a cabin and an airframe where the airframe supports a plurality of rotors and the cabin removably attaches to the airframe. A ground condition is detected and it is decided whether to detach the airframe from the cabin. The airframe is detached from the cabin in response to the decision.

Rotary wing aircraft

A rotary wing aircraft has a nacelle, at least one rotor provided with at least one blade, a braking device to stop the rotation of the rotor, an emergency parachute provided with a canopy and with a rope, a rocket to start the extraction of the canopy from the nacelle, two operating devices to operate the braking device and the rocket, respectively, and a single actuator device to operate both the operating devices.

Aerial vehicle safety apparatus and aerial vehicle

An aerial vehicle safety apparatus includes a safety mechanism, a drive mechanism, an ejection mechanism, and a control mechanism. The safety mechanism is used for securing safety of at least one of an aerial vehicle and an object outside the aerial vehicle. The drive mechanism includes at least one drive unit serving as a drive source of the safety mechanism. The ejection mechanism ejects the drive mechanism together with the safety mechanism. The control mechanism controls operations of the drive mechanism for the drive mechanism to drive the safety mechanism after the ejection mechanism starts ejection of the safety mechanism.

AIRCRAFT PARACHUTE SYSTEM UTILIZING AIRBAG TO ASSIST WITH PARACHUTE DEPLOYMENT

An aircraft includes an airframe parachute system. The parachute system includes an activation system, an extraction system, a harness system, and a parachute assembly.

BRIDLE FOR AIRCRAFT PARACHUTE DEPLOYMENT ROCKET

An aircraft includes an airframe parachute system. The parachute system includes an activation system, an extraction system, a harness system, and a parachute assembly.

Safety device, and flying vehicle provided with safety device

There is provided a safety apparatus including a push-up member in which an ejected object is hardly displaced even during transportation, and an aerial vehicle including the safety apparatus. A safety apparatus 100 includes a cylinder 14 that accommodates a piston member 10 and is provided with a bore 13 through which the piston member 10 protrudes to the outside (upward in FIG. 1) during operation, a push-up member 15 that is pushed up in one direction by the piston member 10, an ejected object 16 that is pushed up while being supported by the push-up member 15, a gas generator 17 as a power source that moves the piston member 10 in the cylinder 14, a container 18 that has a bottomed cylindrical shape and accommodates the piston member 10, the cylinder 14, the push-up member 15, the ejected object 16, and the gas generator 17, and a lid 21 that closes an opening end of the container 18. A movement preventing member 27 that prevents the ejected object 16 from moving in a circumferential direction of a bottomed cylindrical portion 19 is provided on an upper surface of a support 20 of the push-up member 15.

Automated aircraft recovery system

Sensor data is received from a sensor where the sensor data includes aircraft state information including an aircraft pitch angle and recovery device state information including which parachute canopies are operational and one or more properties associated with the operational parachute canopies. The parachute canopies are coupled aft of a center of mass. It is determined, based at least in part on the aircraft pitch angle, whether to generate a control signal associated with maneuvering the aircraft into a nose-up position. A recovery action is performed, including by selecting a parachute canopy to be deployed, from the operational parachute canopies and based at least in part on the one or more properties, and deploying the selected parachute canopy, where a load on the selected parachute canopy is reduced in the event the aircraft is in the nose-up position compared to the aircraft being in a nose-down position.

Emergency parachute
09656758 · 2017-05-23 ·

An emergency parachute is a device for allowing the user to eject from a perilous high-altitude structure and float to safety once clear of the structure. The emergency parachute features a vest that may be donned by the user. The user is required to face toward the structure that he or she is escaping. In order to activate the canopy of the emergency parachute, the user is required to engage a first activation handle and a second activation handle of a simultaneous activation dual switch. The simultaneous activation dual switch ensures that the canopy is not accidentally deployed. A chute-inflation gas generator inflates the canopy and simultaneously ejects the user backward. The ejection serves the twofold purpose of ensuring that the user is able to clear the structure that he or she is escaping as well as aiding the user in overcoming any fears of jumping from a high altitude.
