Claims
- 1. A strut structure for connecting a load carrier device to an aircraft, which comprises:
- (a) a horizontal hollow supporting beam comprising a metal hollow longitudinal member disposed within a first U-sectioned longitudinal member made of compound material comprising mineral fibers embedded in a resin forming a setting binder,
- (b) a metal connecting member to the aircraft rigid with an upper face of said metal longitudinal member and passing through an upper intermediate portion of said first longitudinal member made of compound material,
- (c) a second U-sectioned longitudinal member made of compound material having an intermediate portion rigid with said hollow supporting beam,
- (d) metal members each being provided with means for fixing a load carrier device and being rigid with registering portions of said U-sectioned second longitudinal member, and
- (e) side plates made of compound material fixed on external portions of said first and second U-sectioned longitudinal members made of compound material,
- so that transmission of stress between the load carrier device and the aircraft is performed along two different paths, the one comprising the side plates and the U-sectioned first longitudinal member made of compound material through which passes the metal connecting member while the other comprises said U-sectioned second longitudinal member made of compound material and said metal hollow longitudinal member.
- 2. A strut structure for connecting a load carrier device to an aircraft, which comprises:
- (a) a horizontal hollow supporting beam comprising a metal hollow longitudinal member disposed within a first U-sectioned longitudinal member made of compound material comprising mineral fibers embedded in a resin forming a setting binder,
- (b) a metal connecting member to the aircraft rigid with an upper face of said metal longitudinal member and passing through an upper intermediate portion of said first longitudinal member made of compound material,
- (c) a U-sectioned metal strap disposed under said metal longitudinal member and having an intermediate portion connected thereto through a metal coupling member, said strap being provided with means for fixing a load carrier device,
- (d) a second U-sectioned longitudinal member made of compound material surrounding said metal strap and having an intermediate portion rigid with said U-sectioned first longitudinal member made of compound material,
- (e) an upper U-sectioned longitudinal member of compound material being rigid with an upper portion of said first longitudinal member of compound material and provided with a hole for receiving said metal connecting member, and
- (f) side plates of compound material, being rigid on each side of said structure with an external face of said second longitudinal member of compound material and with a corresponding external face of said upper U-sectioned longitudinal member of compound material,
- so that transmission of stress between the load carrier device and the aircraft is performed along two different paths, on the one hand along a metal chain comprising the metal strap, the metal coupling member, the metal longitudinal member and the metal connecting member and, on the other hand, along a compound material chain consisting of said second U-sectioned longitudinal member, said first U-sectioned longitudinal member, said upper U-sectioned longitudintal member and said side plates.
- 3. A strut structure as claimed in claim 2, wherein stiffening elements made of cellular texture are disposed between said first U-sectioned longitudinal member and said side plates.
- 4. A strut structure as claimed in claim 2, wherein stiffening elements made of cellular texture are disposed between said metal strap and said second U-sectioned longitudinal member.
