ABSTRACT:
A parachute support system for supporting a helicopter emergency parachute is provided, comprising a parachute support shaft located within a main rotor shaft, said parachute support shaft being rotationally separated from the rest of the helicopter through the use of bearing supports or enclosures. As the parachute support shaft is connected to the main rotor shaft at multiple distinct and distant points, the system described also provides a preferable load path transfer route, such that parachute system malfunction is minimized.
