Abstract

The invention provides a rotary connecting head and a three-axis continuous rotation test table by using the same, which belong to the field of flight simulation equipment. The rotary connecting head comprises a rotary seat, a rotary shaft, a pipe inlet duct and a pipe outlet duct. The three-axis continuous rotation test table is communicated with a cooling pipe via the rotary connecting head; the cooling pipe is connected with the pipe outlet duct via the pipe inlet duct; in the case of a rotary test, the rotary shaft rotates to ensure the cooling pipe not to rotate and to be constantly in a communicated state, the cooling pipe is ensured not to result in cold air blocking due to rotation, the cooling effects are improved, and the service life of the cooling pipe is prolonged.

Description

technical field [0001] The invention relates to the field of flight simulation equipment, and in particular to a rotary joint and a three-axis continuous rotation test bench using the rotary joint. Background technique [0002] The rotary test bench is a modern equipment integrating optics, electromechanics, and is used for semi-physical simulation and testing in the fields of aviation and aerospace. It plays a key role in the development of aircraft. It can simulate various attitude angle movements of the aircraft. , reproduce the various dynamic characteristics of the aircraft, repeatedly test the performance of the guidance system, control system and corresponding devices of the aircraft, obtain sufficient test data, and redesign and improve the system according to the data, so as to achieve the overall goal of the aircraft. Design performance index requirements. [0003] The existing three-axis rotating test bench is usually connected with a refrigeration system, and th...
