example 4 to example 6

[0037] With respect to Examples 4-6, the cargo liner 210 may be prepared from a refractory material having a high strength to weight ratio (eg, fiberglass woven cloth), making it suitable for use as a cargo or baggage bay lining. Additionally, any of the system lines 212, 214, 215 may be any part of a number of aircraft systems (including propulsion systems, electrical systems, hydraulic systems, and environmental systems.). Any number of other systems may also be included. By attaching the first system line 212 to the structural struts 206, and the cargo liner 210 to the non-structural struts 208, the system and struts can be installed more efficiently because the system line 212 can be installed first, i.e., without Intervened by non-structural struts 208 and cargo liner 210 .

By attaching the first system line 212 to the structural struts 206, and the cargo liner 210 to the non-structural struts 208, the system and struts can be installed more efficiently because the system lines 212 can be installed first, i.e., not subject to non-structural struts. Structural struts 208 and cargo liner 210 interfere.

Abstract

The invention relates to a fuselage having structural struts and non-structural struts. A fuselage section of a vehicle (eg, an airplane) is disclosed. The fuselage section includes: a frame; a bottom spar attached to the frame and including an end; a structural strut including a first end and a second end; a first structural coupling joining the bottom spar and the first end of the structural strut; a structural coupling that joins the frame and the second end of the structural strut; a nonstructural strut that includes a third end and a fourth end; a first nonstructural coupling that joins the bottom beam and the third end of the nonstructural strut; and a second nonstructural coupling joint to join the fourth end of the framing and nonstructural struts.

Description

technical field [0001] The present invention relates to a vehicle fuselage, and more particularly to a fuselage having structural and non-structural struts. Background technique [0002] Many commercially available aircraft include a floor beam extending between opposite sides of the fuselage and attached to the fuselage frame. The sill supports the floor of the passenger compartment and / or upper cargo compartment. In some designs, vertical struts permanently attached between the sill and frame provide structural support for the sill. However, these struts can present difficulties in the installation of various system lines such as wiring harnesses, hydraulic lines, air conditioning ducts, and the like. Other fuselage designs utilize deep sills and locally reinforced frames to achieve the necessary structural stability without the use of struts to support the sill. However, this approach reduces the space available in the passenger compartment and / or cargo compartment. ...
