A reusable aircraft model experimental device that can change shape and parameters

Abstract

The invention presents a recyclable airplane model experimental facility capable of changing an appearance and a parameter. The recyclable airplane model experimental facility comprises a bracket structure used for supporting an airplane model, a plane body structure with variable length, a plane body outer shell cowling, and a control box; the bracket structure used for supporting the airplane model comprises a lower bracket, an electric motor, a hydraulic actuator cylinder and an upper bracket; the plane body structure with the variable length comprises a middle grid trough beam, a front grid trough beam, a rear grid trough beam, a plane body balance and a spoiler grid trough beam. By adopting the airplane model experimental facility, length of the front plane body can be changed by adjusting an installing position of a card between the front grid trough beam and the middle grid trough beam; the length of the rear plane body can be changed by adjusting the position of installing the rear grid trough beam on the spoiler grid trough beam, thus the change of the plane body length of the airplane model can be realized. Through mounting the plane body cowlings with different appearances and layouts at the outer part, different airplane experimental models can be structured.

Description

technical field [0001] The invention relates to a model experiment device, in particular to a reusable aircraft model experiment device which can change its shape and parameters. Background technique [0002] In the design and manufacture of fixed-wing aircraft and rotary-wing aircraft, wind tunnel experiments and ground experiments are often required. In order to save costs, wind tunnel experiments and ground experiments often use aircraft models to simulate real aircraft. A new concept aircraft often needs to verify its key technologies, and the verification process is often carried out with an aircraft model that has key features of the new concept aircraft. [0003] Most of the aircraft models currently used are wooden or metal disposable aircraft models, which cannot be reused, and the shape and parameters cannot be changed quickly. When a large number of experiments are carried out on the aircraft, and the design parameters need to be changed according to the experime...
