Separation release centrifugation gravity compensation device and method

Abstract

The invention relates to a separation release centrifugation gravity compensation device, which comprises a rotating platform, a rotating arm, a rotating counterweight and a rotating bar; the rotatingplatform is vertically fixed on the ground; a motor is installed at the top end of the rotating platform; the rotating arm is vertically fixed on the top end of the rotating shaft of the motor on therotating platform; the rotating shaft of the motor drives the rotating arm to rotate around the rotating platform; one end of the rotating bar is sleeved in the rotating arm, and the other end stretches out of the rotating arm along the rotating arm; an aircraft model under test is fixed at the end part of the rotating bar; and, a separation model is installed on the aircraft model under test. The installation posture of the aircraft model can be adjusted, so that the separation direction of the separation model is the extension line direction of the rotating bar; the rotating arm and the rotating bar rotate around the rotating platform; the centrifugal force generates the separation acceleration; and thus, the separation model is released when the aircraft model under test rotates to theseparation point.

Description

technical field

[0001] The invention relates to mechanical design and wind tunnel test, in particular to a technology and method for centrifugal gravity compensation of separation and delivery, belonging to the fields of mechanical design and aerospace engineering. Background technique

[0002] The aircraft model wind tunnel test plays an important role in the initial stage of aircraft development. A major feature of the wind tunnel test is that various parameters of the real aircraft are similarly scaled, and the test is carried out on the scaled model. The data obtained from the test are reversed by the similar scale formula. All kinds of aerodynamic parameters of the real aircraft can be obtained through directional calculation. In the wind tunnel free flight model test, the size of the model is often much smaller than that of the real aircraft. In practice, it is often necessary to scale down a real missile several meters long into a test model of the size of a ballpoint...
