Embodiment Construction

[0023] Such as figure 1 As shown, the present invention provides a hanger for an aerospace vehicle landing approach flight test, which is characterized in that it includes: a steel cable 1, a welded steel frame 2, a fixed ring 3, an adapter ring 4, a lifting point connection box 5, a stable Umbrella connection structure 6, presser foot 7, elevation plate 8 and stable umbrella 9;

[0024] Such as figure 2 As shown, the welded steel frame 2 is a truss structure, its symmetrical plane is a triangular cross structure, and the material is No. 20 steel with good welding performance. One end of the five steel cables 1 is snapped together and fixedly connected by bolts, and the other end is connected to a fixed ring 3, and the adapter ring 4 is fixedly connected to the welded steel frame 2, and the fixed ring 3 and the adapter ring 4 are engaged And fixed connection by bolts, such as image 3 shown. Five adapter rings 4 are distributed on the four corners of the welded steel fram...

Abstract

An aerospace vehicle landing approach flight test hanging rack comprises a steel cable, a welding steel frame, a fixing ring, a connecting ring, a hanging point connecting box, a stabilization parachute connecting structure, a presser foot, an elevation plate and a stabilization parachute. By the hanging rack structure and an aerospace vehicle and the adjustable compensation function of the mechanical connecting port of the hanging rack structure and the stabilizing device, stabilization of the aerospace vehicle during hanging flight is achieved. The steel cable of the hanging rack is fixed with the central steel cable of a helicopter through connectors and bolts. The hanging rack is connected with the aerospace vehicle through a front explosion bolt and a rear explosion bolt. Due to the fact that the hanging rack steel cable connector is the connecting ring with the length adjusting function, gravity variation of the aerospace vehicle can be adapted to, and stable hanging can be guaranteed.

Description

technical field [0001] The invention relates to a flight test pylon for landing and approaching an aerospace vehicle, in particular to an aircraft flight pylon that meets the high stability and self-adaptive requirements of a helicopter carrier. Background technique [0002] The pylon is an important part of the autonomous approach flight test of the aerospace vehicle. It plays the role of connecting the aircraft and the carrier aircraft, stabilizing the attitude of the aircraft, transferring loads, and realizing the safe separation of the carrier aircraft and the aircraft. It plays a vital role in the success of the flight test. important role. At present, in the flight test of aircraft, there is no pylon for helicopter flight in China, and the hanger is used to hang on the fixed-wing carrier itself or use a standard simplified hanger. The existing foreign helicopter pylons are highly dependent on the specific model of the aircraft, have poor interface adaptability, and ca...
