Braking power test method of brake device of high kinetic energy aircraft

Abstract

The invention relates to a braking power test method of a large kinetic energy aircraft braking device. At present, the carbon braking device of large aircraft can absorb kinetic energy up to 85MJ, 105MJ, and 125MJ at one time, and the output energy of the inertial table cannot fully meet the requirements of the test program. The purpose of the invention is to provide a braking power test method for a braking device of a large kinetic energy aircraft. The method is that when the kinetic energy provided by the inertial table cannot meet the kinetic energy requirements stipulated in the test program, in the domestic multi-disc brake device, the carbon brake disc is installed in the middle of the brake device, and consists of several static discs (4), moving discs (3 ) are arranged in a staggered manner, while keeping the absorbed kinetic energy QF of the unit friction surface unchanged, by reasonably reducing the number of friction surfaces NT, the energy absorbed by the primary braking device of the wheel or the main wheel AS is required for the kinetic energy of the inertial table. Realize the braking power test method of the large kinetic energy domestic aircraft brake device and avoid the phenomenon of wheel or main wheel locking during the test.

Description

1. Technical field: [0001] The invention relates to a test method for an aircraft carbon brake device in a bench test when the energy provided by a brake power test bench cannot meet the energy requirements of a test program, and specifically refers to a brake power test method for a large kinetic energy aircraft brake device. 2. Background technology [0002] At present, the aircraft used by China's civil aviation are mainly imported Airbus A320, A319, A321 and Boeing B757, B767 and other models. In recent years, many large-scale A330, A340 and so on have been imported. In recent years, my country has made considerable progress in the localization of civil aircraft carbon discs, and progress has been made in the localization of all carbon brake discs for aircraft to replace imported ones. During the development process, the dynamic test of the brake device is the main identification before the test flight. means of performance. With the rapid development of my country's air...
