Abstract

The invention discloses a dynamics comprehensive test bed for a half-unfolding gas bomb with a long tilting rotor wing, comprising a wing, a tilting driving mechanism, a tilting rotor wing nacelle and a power-driven system, wherein the power-driven system is arranged at one end of the wing, the other end of the wing is connected with the tilting driving mechanism, and the tilting driving mechanism is also connected with the tilting rotor wing nacelle and drives the tilting rotor wing nacelle to rotate. By using the structure, the deficiency in test means in research filed of tilting rotor wing gas bomb dynamics problems in China is solved, and the invention provides the test bed capable of researching the stability, tilting transition state dynamic test and vibration control of the tilting rotor craft, which can be used for checking theoretical analysis results.

Description

Technical field [0001] The invention belongs to the field of aviation, and relates to a test platform, in particular to a test device for aerodynamics research of a tilting rotor. Background technique [0002] The tilt-rotor aircraft is a new type of rotary-wing aircraft. It places a tilting nacelle with a rotor on the wing end of the wing. It combines the advantages of a helicopter vertical take-off and landing and a rapid forward flight of the aircraft, showing a huge military Value and civilian potential. Tilt-rotor aircraft not only has the advantages of helicopter vertical take-off and landing and aircraft fast forward flight, but also has all the dynamic problems of helicopters and propeller aircraft. Compared with the coupling between the rotor body of a conventional helicopter or the coupling between the propeller and wings of an aircraft, The various coupling relationships of tiltrotor aircraft are more complicated, especially during the transition process between the t...
