Abstract

The invention provides a free jet test cable removal device, which is composed of a removal connecting rod 3, a rotary hinge support 5, and an actuating mechanism; the removal connection rod 3 is hollow L-shaped, and one end of the removal connection rod 3 It is connected with the plug protection sleeve 15; the pull-out plug 13 and the cable 4 are located in the plug protection sleeve 15 and the pull-out connecting rod 3; the pull-out plug 13 is connected with the pull-out connecting rod 3, and the actuating mechanism drives the pull-out connecting rod 3 Do rotary motion, will take off and pull out plug 13 and pull out. The invention can accurately complete the unplugging action of the cable during the free jet test, accurately simulate the separation of the cable when the aircraft is separated from the booster stage; It is ablated and destroyed by the high-temperature gas of the nozzle and the airflow of the flow field.

Description

A kind of free jet test cable pull-out device Technical field [0001] The present invention relates to a free jet test cable removal device. Background technique Aircraft can carry out a series of such as separating with booster machinery when real flight, booster and aircraft electric The air interface is mechanically separated, the fairing is separated from the aircraft structure, and the rudder blades are moved to control the flight attitude and other actions. while flying During the development process of the aircraft, it is necessary to simulate the relevant actions on the ground to check the reasonableness and feasibility of the designed aircraft. Rely on, to ensure the successful realization of the flight test. The product size that carries out free jet test is limited by the size of wind tunnel, and each free jet test is particularly large The size of the wind tunnel free jet test requires a relatively large amount of funds. At present, in China, it is possi...
