Problems solved by technology

[0008] However, the above-mentioned protective devices are only aimed at multi-rotor type aircraft and are mainly concentrated in the field of unmanned aerial vehicles
For aeroelastic flight test rigs, as usually involves fixed-wing aircraft models, the above protective devices are not suitable for fixed-wing aircraft models, because the two crashes occur in completely different ways

Embodiment Construction

[0059] The structure of the crash protection device for a fixed-wing aircraft model of the present invention will be described below with reference to the accompanying drawings, wherein the same components are marked by the same reference numerals.

[0060] The crash protection device according to the invention consists of a passive protection device and an active protection device.

[0061] figure 1It shows the passive protection device equipped on the aircraft model, the passive protection device is mainly composed of F distributed in the model nose and model tail. Of course, those skilled in the art should understand that other cushioning materials can also be used to replace the cushioning foam F, or the cushioning foam F can be arranged on only one of the model nose and the model tail. These modifications should all fall within the protection scope of the present invention.

[0062] The passive protection device fills the model nose and tail with cushioning foam F to ab...

Abstract

The invention relates to an air crash protection device for a fixed-wing aircraft model. The air crash protection device is composed of at least one of a passive protection device and an active protection device, so that the fixed-wing aircraft model and/or airborne equipment on the fixed-wing aircraft model are/is protected during air crash of the fixed-wing aircraft model. The passive protectiondevice is composed of buffer materials (F) distributed on the nose and the tail of the fixed-wing aircraft model. The active protection device comprises a control assembly (1), an inflation device (2), an inflation catheter (3) and an air bag (4). According to the air crash protection device, on one hand, the space of the airborne equipment is not additionally occupied, and on the other hand, theairborne equipment can be rapidly and timely protected.

Description

technical field [0001] The invention relates to a crash protection device, more specifically, relates to a crash protection device for a fixed-wing aircraft model. Background technique [0002] The flight test of aeroservoelasticity based on scale model is an innovative comprehensive verification technique. This technology not only synthesizes many advantages of the existing aeroelastic verification technologies, but also avoids the deficiencies of these aeroelastic verification technologies. [0003] During the application of the flight test platform, it is inevitable that the aircraft model will fall due to various reasons (for example, aircraft model failure, power plant shutdown, pilot operation error, etc.). This situation will not only cause the aircraft model to be unusable due to the damage of key airborne equipment (such as data acquisition equipment, storage equipment, etc.) on it, but also cause safety hazards to ground personnel. [0004] Therefore, it is neces...
