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.

Parachute deployment system using decoupled tow and release lines

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.

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.

Aerial vehicle safety apparatus and method of accommodating expandable object in aerial vehicle safety apparatus
11981442 · 2024-05-14 ·

An aerial vehicle safety apparatus includes a piston member, a cylinder that accommodates the piston member and is provided with a hole through which the piston member protrudes outward at time of operation, a push-up member that is pushed up in one direction by the piston member, an expandable object that is pushed up while being supported by the push-up member, a gas generator as a power source that moves the piston member in the cylinder, and a first member and a second member that serve as a cylindrical container that accommodates the piston member, the cylinder, the push-up member, the expandable object, and the gas generator. The expandable object is stored in the container so as to form a plurality of layers in a radial direction.

Intelligent ballistic parachute system that performs pre-activation and/or post-activation actions
RE047474 · 2019-07-02 ·

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.

Impact velocity reduction by mass ejection
10322817 · 2019-06-18 · ·

A ballistic parachute associated with an aircraft is deployed where the aircraft includes a first part and a second part, the two parts are detachably coupled to each other when the ballistic parachute is deployed, and the ballistic parachute is coupled to the first part of the aircraft. A landing zone associated with the second part of the aircraft is determined and it is decided whether to decouple the two parts, including by deciding whether the landing zone associated with the second part of the aircraft is inhabited. If it is decided to decouple the two parts from each other, they are decoupled from each other.

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.

PARACHUTE DEVICE FOR A DIVISIBLE SHELL

A parachute device is provided for a divisible shell that includes an active body and a shell base. The parachute device includes two parachutes, a first, main parachute connected to the active body by parachute lines and a second parachute connected to the shell base.

Preferred break points and paths in airframes for ballistic parachute systems
10273013 · 2019-04-30 · ·

A preferred break point is provided in the airframe, where there is a ballistic parachute system which includes a rocket which sits in a rocket canister and a canopy which sits in a canopy canister. The airframe includes a composite material and covers the ballistic parachute system. The preferred break point is located in the airframe over the opening of the rocket canister. A preferred break path is provided in the airframe located at least partially over the opening of the rocket canister and at least partially over the opening of the canopy canister.
