Problems solved by technology

[0004] However, due to the limited space in the built-in weapon compartment of the carrier aircraft in the prior art, the existing embedded weapon launching mechanism cannot realize such a backward way to launch the built-in aircraft; at the same time In the prior art, there is no test device that can be used to simulate the real flight conditions of the missile in the backward mode of launching and separating. This type of device requires the built-in aircraft to be firmly clamped by the launching mechanism before being launched, and the built-in aircraft must be guaranteed to be separated when it is separated. In a free state, it is not disturbed by other forces except the one-way ejection force of the launching mechanism, so it is difficult to observe and analyze the separation dynamic characteristics of the missile at different exit speeds in the wind tunnel

Embodiment Construction

[0032] The following describes the present invention in detail, and the features and advantages of the present invention will become more clear and definite along with these descriptions.

[0033] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as superior or better than other embodiments. While various aspects of the embodiments are shown in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

[0034] The present invention realizes the backward separation of the built-in aircraft on the basis of the model test in the wind tunnel, so that the built-in aircraft is in the state of free flight during the backward separation process, and can more realistically simulate the actual flight state in the wind tunnel The backward separation process and the influence and interference of the carrier aircraft o...

Abstract

According to a launching mechanism for a backward separation wind tunnel launching model test provided by the invention, a clamping mechanism can push out a built-in aircraft at a certain speed without being completely opened by adopting a mode of combining multiple sections of slide ways, so that the limitation of a weapon cabin space is broken through, and after a built-in aircraft model and a carrier aircraft are separated according to a certain speed, the built-in aircraft model freely flies in a wind tunnel flow field without being restrained; and meanwhile, through the shape design of each structural surface of the I-shaped launching claw and the matching of the I-shaped launching claw and the slide way, the stable clamping and separation of the built-in aircraft are realized. The launching mechanism can be used for realizing analysis of dynamic separation aerodynamic characteristics in a release and separation process of a built-in aircraft model in a wind tunnel, analysis of influence and interference of a carrier flow field on the built-in aircraft model, and research of a dynamic flight motion track of the separated aircraft, so that simulation of a backward separation process of the built-in aircraft is realized.

Description

technical field [0001] The invention provides a launch mechanism for launching a model test in a backward separation wind tunnel, which is applied to a model test for launching an aircraft in a wind tunnel in which a built-in aircraft is separated from a fixed carrier aircraft, so that it can be launched backward in the wind tunnel and separated from the carrier aircraft, and In turn, it is a test mechanism for the built-in aircraft to fly unrestricted and freely in the wind tunnel flow field. Background technique [0002] The process of ejecting the built-in aircraft from the carrier aircraft out of the cabin at a set speed and flying freely is called release separation. The fourth-generation aircraft is mainly characterized by supersonic stealth operations. The missiles and other combat weapons carried by it are installed in the buried weapon compartment before being launched out of the compartment. When the target appears within the effective range of the missile, the fig...
