A device is provided for preventing a parachute from being damaged. A parachute device (4) includes a flying body (43) including a parachute (400), a parachute accommodation section (40) configured to accommodate the parachute, at least one flying body (43) connected to the parachute, an ejection section (41) having a tube shape and configured to hold the flying body and to eject the held flying body, a gas generating device (60) configured to generate gas, and an extrusion member (42) capable of being at least partially inserted into the ejection section, the extrusion member being configured to extrude the flying body from the ejection section due to receiving pressure of the gas generated from the gas generating device.

A neck protection system for a parachute assembly may comprise a head restraint, a first upper strap coupled to a first side of the head restraint, and a second upper strap coupled to a second, opposing side the head restraint. A first lower strap may be coupled to the first side of the head restraint. A second lower strap may be coupled to the second side of the head restraint. A first pull cord may be coupled to the first upper strap. A second pull cord may be coupled to the second upper strap.

Sensor data that includes or more of the following: (1) aircraft state information associated with an aircraft or (2) parachute canopy state information associated with a parachute canopy is received. The parachute canopy is coupled to the aircraft at a point aft of a center of mass of the aircraft. It is determined, based at least in part on the sensor data, whether to generate a control signal associated with maneuvering the aircraft into a nose-up position. A recovery action is performed, including by deploying the parachute canopy; wherein a load on the 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.

In an embodiment, a system to deploy a plurality of parachutes includes a plurality of parachute canopies each packed in a canister, a plurality of rockets adapted to extract an associated canopy from the canister, and a controller. The controller is configured to determine that an aircraft is at least one of: in a hover mode of operation and a forward flight mode of operation. In response to the determination that the aircraft is in the hover mode of operation, the controller applies a hover deployment sequence including by instructing the plurality of parachutes to deploy substantially simultaneously. In response to the determination that the aircraft is in the forward mode of operation and above a threshold airspeed, the controller applies a forward deployment sequence including by instructing the plurality of parachutes to deploy in a predefined sequence.

The invention relates to a device (1) for ejecting a parachute, comprising a housing (2) with an ejection opening (3), wherein the housing (2) is suitable for at least partially accommodating the parachute. In order to enable a robust and repeated ejection of the parachute with a low weight of the device (1), according to the invention a movable base (4) is arranged within the housing (2), which base (4) is connected to the housing (2) via at least one spring element, wherein the base (4) can be releasably fixed in place within the housing (2) using a fixing means (5), wherein the device (1) is configured such that if a parachute is arranged within the housing (2), the base (4) is accelerated by the spring element when the fixing means (5) is released, so that the parachute is ejected through the ejection opening (3) by means of the base (4). Furthermore, the invention relates to a method for ejecting a parachute.
