Abstract
A separable aircraft cabin module is provided with parachutes that are dynamically and independently reefed in order to safely deliver the cabin module, and its occupants from a separation from a main aircraft body at altitude and speed to a landing. The arrangement includes a rear parachute and two front parachutes which particularly handle the cylindrical shape of the cabin module through the various stages after separation from the main aircraft body.
Claims16
A dynamic parachute reefing system for a separable aircraft cabin module, the aircraft cabin module having a cylindrical shape, comprising:
- two parachutes disposed at a forward end of the cabin module and at least one parachute disposed at a rear of the cabin module;
- each of the parachutes including reef lines that are each controlled by respective reefing motor;
- a controller that is configured to control the reefing motors to dynamically control a reef state of each one of the parachutes upon deployment after separation of the cabin module from an aircraft main body, to control deceleration of the cabin module, a decent speed of the cabin module, and a landing of the cabin module.
A separable cabin module for an aircraft, comprising:
- a cylindrical body having a front end and a rear end;
- a rear parachute initially stored and connected to the rear end, and a first front parachute and a second front parachute that are each initially stored and connected to the front end;
- each of the rear parachute, first front parachute, and second front parachute including a reefing ring;
- a rear reefing motor at the rear end that is coupled by a rear reefing line to the reefing ring of the rear parachute;
- a first front reefing motor at the front end that is coupled by a first front reefing line to the reefing ring of the first front parachute;
- a second front reefing motor at the front end that is coupled by a second front reefing line to the reefing ring of the second front parachute;
- and
- a controller the receives input regarding at least an altitude of the cabin module, a velocity of the cabin module, and pitch, roll, and yaw of the cabin module, and which in response controls each of the rear reefing motor, first front reefing motor, and second reefing motor to independently and dynamically control a reef state of each of the rear parachute, first front parachute, and rear parachute in response to the altitude, velocity, pitch, roll, and yaw of the cabin module through deceleration, descent, and landing stages.

- a main aircraft body;
- a cabin module separably disposed in the main aircraft body having a front end and a rear end and including:
- a rear parachute initially stored and connected to the rear end, and a first front parachute and a second front parachute that are each initially stored and connected to the front end;
- each of the rear parachute, first front parachute, and second front parachute including a reefing ring;
- a rear reefing motor at the rear end that is coupled by a rear reefing line to the reefing ring of the rear parachute;
- a first front reefing motor at the front end that is coupled by a first front reefing line to the reefing ring of the first front parachute;
- a second front reefing motor at the front end that is coupled by a second front reefing line to the reefing ring of the second front parachute;
- and
- a controller the receives input regarding at least an altitude of the cabin module, a velocity of the cabin module, and pitch, roll, and yaw of the cabin module, and which in response controls each of the rear reefing motor, first front reefing motor, and second reefing motor to independently and dynamically control a reef state of each of the rear parachute, first front parachute, and rear parachute in response to the altitude, velocity, pitch, roll, and yaw of the cabin module through deceleration, descent, and landing stages.
