A separation and delivery centrifugal gravity compensation device and method

Abstract

The invention relates to a centrifugal gravity compensation device for separation and delivery. The device includes a rotating table, a rotating arm, a rotating counterweight, and a rotating rod; the rotating table is vertically fixed on the ground; On the top of the rotating shaft of the rotating table motor, the rotating arm driven by the motor rotating shaft can rotate around the rotating table; one end of the rotating rod is sleeved in the rotating arm, and the other end extends along the rotating arm to the outside of the rotating arm, and the end is used to fix the loader model under test. A separation model is installed on the carrier model under test, and the installation attitude of the carrier model can be adjusted to ensure that the separation direction of the separation model is the direction of the extension line of the rotating rod; the rotating arm and the rotating rod rotate around the rotating table, and the centrifugal force generates separation acceleration. When the carrier model under test rotates to the separation point, release the separation model.

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...
