Problems solved by technology

[0004] Because different aircraft models have different electrical parameters and simulation conditions, the icing wind tunnel site needs to provide several sets of related anti-icing control systems for different aircraft models, and it will be very difficult to install and debug when conducting different test objects. Huge and tedious work, and there may be a risk of inaccurate test accuracy due to equipment compatibility

Embodiment Construction

[0037] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0038] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0039] First of all, understand the working mode of the electric heating anti-icing / de-icing control of the aircraft model, whether to use the aircraft model to match the anti-icing / de-icing controller, or to provide a complete set of electric heating anti-icing / de-icing control system. Learn more about the number of electric heating units of the aircraft model, the maximum power of the heating unit for anti-icing / de-icing, the type of power s...

Abstract

The invention discloses an airplane model electric heating anti-icing / de-icing control system structure, which comprises a heating power supply, electric heating branches, a temperature signal patrolinstrument, a power transfer box, a temperature signal transfer box, an anti-icing / de-icing controller and various cables and the like. Through switching and wiring, the same system can meet electricheating anti-icing / de-icing control test of different airplane models, can only provide the heating power supply for electric heating anti-icing / de-icing control test of the airplane model and can also provide the heating power supply and temperature closed-loop control of the plurality of electrical heating branches for the electric heating anti-icing / de-icing control test of the airplane model;the temperature closed-loop can adopt voltage regulating to continuously control electric heating and on / off of the electric heating branches to realize control of electric heating; an aircraft modelheating unit can realize temperature feedback through a thermal resistor or a thermocouple; and according to the load, the electric heating branches can run independently or in parallel.

Description

technical field [0001] The invention relates to the field of wind tunnel tests, in particular to an aircraft model electric heating anti-icing / deicing control system structure. Background technique [0002] Anti-icing / de-icing technology is one of the key technologies in the development of modern high-performance aviation weapons, and its development will directly affect the success or failure of the development of weapons and equipment. In order to prevent some parts of the aircraft from icing, or to remove the ice layer intermittently when icing, and to ensure the safe flight of the aircraft when icing accumulates, it is necessary to adopt appropriate anti-icing and deicing technologies. Aircraft anti-icing and de-icing technology can be divided into mechanical de-icing technology, liquid anti-icing technology and thermal anti-icing technology according to the working mode. factors such as power, the size of the surface to be protected, and the importance of ice protectio...
