Airplane test bed

Abstract

The invention provides an airplane test bed. The test bed includes a nose section bench for installing a simulated cockpit and a nose landing gear system; a forebody transition bench for connecting the nose section bench with a middle fuselage section bench, as a passageway for the personnel and equipment; the middle fuselage section bench for installing a main landing gear system and a hydraulicsystem; a middle and rear fuselage transition bench for connecting the middle fuselage section bench and an empennage section bench; the empennage section bench for installing an elevator, a rudder surface and an actuation system; a left wing section bench for installing a left aileron, a spoiler, a flap rudder and an actuation system; and a right wing section bench for installing a right aileronand the like. The airplane test bed provided by the embodiment of the invention can reduce the correlation of the structure design of the airplane test bench and the design requirement of the overallstrength and rigidity of the bench, the natural frequency of the airplane test bench is improved, the production, processing, installation, fixation, disassembly and maintenance of the airplane test bench are facilitated, and the production and modification costs of the airplane test bench are decreased.

Description

technical field [0001] The invention relates to the technical field of aviation tests, in particular to an iron bird test bed. Background technique [0002] In the development process of the aircraft iron bird comprehensive test bench, the iron bird bench is the main carrier of the iron bird comprehensive test bench, which undertakes the functions of installing and supporting the tested system and test equipment, providing workbench and working channel, etc. [0003] Since the landing gear, flight control rudder surface loading test, rudder surface frequency sweep test and other test items are to be carried out on the Iron Bird comprehensive test bench, the Iron Bird bench as a supporting platform must have sufficient rigidity and strength to prevent loading or rudder surface damage. During the frequency sweep test, the bench will be deformed, vibrated or damaged, which requires that the natural frequency of the iron bird bench meet certain requirements to avoid resonance wh...
