Abstract:
A selection is made between single stage and multistage parachute deployment for a vehicle based at least in part on vehicle state information. In the event multistage parachute deployment is selected, a drogue parachute is deployed during a first deployment stage and afterwards, a main parachute is deployed during a second deployment stage. In the event single stage parachute deployment is selected, at least the main parachute is deployed in a single stage where in the event the drogue parachute is deployed during the single stage, the drogue and main parachute are deployed simultaneously.

Abstract:
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.

Abstract:
In an embodiment, a parachute deployment system includes a parachute coupled to a release via a first load path. The first path includes crown lines. The release is adapted to attach the parachute to a rocket via the crown lines, and disengage the parachute from the rocket if a load shifts from the first path to a second path. The system also includes a line constrainer between the release and the parachute. The crown lines pass through the line constrainer, and the line constrainer is adapted to restrict an extent to which the crown lines are able to extend away from a longitudinal axis. An example release includes a back plate configured to couple a tow line to crown lines and a soft pin. The pin is adapted to separate from the back plate in response to tensioning of the release line, causing the parachute to disengage.
