Abstract

The invention belongs to the technical field of aviation flight tests, and particularly relates to a gravity center adjustment device for a transport plane test. A miniature horizontal type liquid storage tank is mounted on a large-sized transport plane in a distributed manner. In a transport plane test process, the change of a gravity center needs to be simulated; and the former simulation operation is mainly carried out by adopting solid weight balancing, but the mode is low in flexibility, poor in simulation effect and large in error, so that the test needs to be assisted by a new simulation mode. The miniature horizontal type liquid storage tank disclosed by the invention is a liquid storage device which is simple and reliable in structure and convenient to mount and disassemble and can meet the requirement and safely and effectively store liquid mediums on an air plane; a mounting bracket is stabilized and reinforced by a cross beam; and connection of the mounting bracket and the air plane fixes the whole horizontal type liquid storage tank.

Description

technical field [0001] The invention belongs to the technical field of aviation flight tests, and in particular relates to a center-of-gravity adjustment device for transport aircraft tests, which adopts miniaturized horizontal liquid storage tanks and is distributed and installed on large transport aircraft. Background technique [0002] During the test of the transport aircraft, it is necessary to simulate the change of the center of gravity. The previous simulation was mainly carried out with solid counterweights. This method has poor flexibility, poor simulation effect and large errors. Therefore, a new simulation method is needed to assist the experiment. Contents of the invention [0003] The liquid medium has the advantages that the solid medium does not have, and a center of gravity adjustment device using the liquid for the transporter test is provided. [0004] A center-of-gravity adjustment device for transporter tests, used to simulate the distribution of pass...
