Baggage or freight hold with aerodynamic lines which are suitable for reducing the drag CX, forming a fairing for the main landing-gear bay under the fuselage of aircraft

摘要

Baggage or freight hold device for an aircraft with landing gear under the fuselage, the device combines the volume necessary for a fairing by extending the aerodynamic lines of the gear bay (1) with a part of the volume available under the cabin floor, obtained by a reduction in the curvature of the fuselage bottom frames (7), the fairing hold assembly (2) is stiffened longitudinally by a central panel forming a beam (9). Preformed panels (11) each incorporating an access with a shield-shaped door (12) are fixed onto the main frames (3) (4) (5) on the central panel (9) and along a ledge (10) which longitudinally fixes the upper shape of the hold (2), a flap (15) loaded by a spring sets the pressure level in the fairing hold which is temperature-controlled by a flow of cabin air calibrated through an orifice. This device is particularly suitable for releasing baggage hold space in the cabin of aircraft equipped with a landing gear under the fuselage and requiring an aerodynamic fairing.
