Retractable captive flight support for external hanging equipment

Abstract

The invention discloses a retractable captive flight support for external hanging equipment, which is arranged at a central cap of a base plate of an aircraft cabin and comprises a fixed guide framework, a movable frame, a movable pull rod, movable pulleys, a rocker arm mechanism, a cover plate and a butt-joint frame plate, wherein the fixed guide framework is connected with the base plate of the aircraft cabin and connected with the movable frame through a concave guide rail, the lower end of the movable pull rod is mounted on the movable frame, the upper end thereof is connected with a pull rod fixing seat arranged at the front end of the cabin cap through a positioning pin, the pull rod fixing seat is fixed on the base plate of the aircraft cabin, the lower frame of the movable frame is welded with the butt-joint frame plate, the movable pulleys are respectively arranged at the right and left ends of the movable frame, and the rocker arm mechanism is arranged at one side of the fixed guide framework through a fixing seat. The retractable captive flight support of the invention has the advantages of good generality, secure folding and unfolding, ability of independently completing captive flight experiments of various guiding heads without developing special equipment, safety and convenience, short and simple experiment organization cycle and greatly-reduced experiment cost.

Description

technical field [0001] The invention relates to a support for external hanging equipment used in flight, in particular to a retractable flying support for hanging external equipment. Background technique [0002] The performance of the airborne equipment of the aircraft not only needs to be verified by ground tests and experiments, but also must be verified by the flight test, because the flight test is the most effective means to verify the performance of the external equipment, and can truly simulate various actual use conditions of the external equipment. Such as dynamic environment, visibility, light intensity, target characteristics, etc., so as to verify whether the performance of the external equipment meets the requirements in the actual use environment. Generally, the hanging test of external equipment requires the design of the flying pod, and the communication between the pod and the aircraft needs to be coordinated. According to the agreement, special pods and co...
