Claims40
A primary flight structure comprising:
- a load bearing composite shell defining at least the exterior of a helicopter fuselage, the fuselage defining at least a central fuselage section and tail boom,
- wherein the central fuselage section is adapted enclose at least one of an engine or drive train.
(canceled)
An enclosure for a primary flight structure for a helicopter adapted to provide protection for one or more fuel cells, the enclosure comprising at least four upstanding panel members spanning between an upper and lower internal surface of a substantially enclosed composite fuselage or outer shell of a flight structure, at least two panel members having a surface extending laterally relative to the interior of the fuselage or outer shell of the flight structure interior and attaching to the internal surface of the fuselage at least in an upper and lower region thereof, and at least two panel members extending longitudinally to the interior of the fuselage or outer shell of a flight structure interior and attaching to the interior surface of the fuselage at least in an upper and lower region thereof, the panel members defining an enclosed space.
