Description
Technical Field
The invention relates to an aircraft brake temperature measuring system and method.
Background
In model development, various problems can be caused from design to verification of brake energy, for example, the heat absorption capacity of a brake heat reservoir is insufficient or excessive due to inaccurate brake energy indexes, and for example, the fusible plug cannot be melted according to the design temperature when the integrity of the fusible plug is tested due to the brake energy. At present, the main stream civil aircraft adopts a brake temperature monitoring system as follows: a brake temperature probe (K-type thermocouple) is arranged in the brake heat reservoir to acquire brake temperature information; then, the brake temperature information is transmitted to a brake temperature compensation module for temperature compensation; then, the brake temperature information after data compensation is transmitted to a brake control unit or a data acquisition unit through an in-shaft adapter; and after data processing, the brake temperature information is sent to an aircraft avionics network, stored and displayed to a pilot in a cockpit.
For example, li bing, xiao yang et al in the patent "airplane brake cooling system and method" (CN105752053A) propose a method for collecting brake temperature information by infrared ray; wangkun, Luoho, et al, in the patent "airplane brake temperature sensor and airplane brake temperature monitoring system" (CN207066626U), is a utility model patent, structurally different from the mainstream civil airplane brake temperature monitoring system, but similar in principle; the patents of the companies such as airbus, Safe Flight and the like on the brake temperature monitoring system are similar to the brake temperature monitoring system of the mainstream civil aircraft in principle.
However, the prior art can only measure the value of the brake temperature, and cannot give a measurement result to the temperature field information of the wheel brake assembly. Because the brake temperature sensor in the prior art is installed in the brake hot reservoir, the measured temperature is only the direct temperature of the hot reservoir, and the temperature information of each part of the wheel brake assembly cannot be analyzed, so that the change condition of the whole temperature field of the wheel brake assembly and the heat conduction condition among all parts cannot be reasonably analyzed.
Accordingly, there is a need for systems and methods that ameliorate the deficiencies of the prior art.
