| Description |
In the process of braking, the multi-disc brakes of transport aircrafts are prone to the action of dynamical (forces: inertia, circumferential, radial and friction) loads, and as a consequence, thermal loads. The last one significantly affects the wear and friction properties of multi- friction units. Reducing the power of brake discs is an important problem, which is reflected in the materials of this article. Transport engineering, and in particular aircraft construction, makes extensive use of modern braking systems. It is known that aircraft landing devices in operation are characterized by a high specific strength and thermal loading, in addition, it is also characterized by a landing gear impact when the kinetic energy is also transformed into thermal energy. In addition to these units, other wheel parts are subject to significant thermal stress, i.e. drum and tires. The impact of aperiodic heating and cooling cycles over the "landing-parking" time intervals of a plane largely determines both the durability of the wheel drum and the efficiency of the brake disc package. The purpose of the work is to improve the wear-frictional properties of friction pairs of disc brakes by reducing their energyloading. Multifactor analysis of the parameters of vari- ous types of brake discs made of steel 20X13, beryllium and carbon, with structural improve- ments in the lateral surfaces of the discs, made it possible to evaluate the efficiency of their air cooling.
— В процессе торможения многодисковые тормоза транспортных самолетов подвержены воздействию динамических (сил: инерции, окружных, радиальных и трения) нагрузок, и как следствие, тепловых нагрузок. Последние суще- ственно влияют на износо-фрикционные свойства многопарных узлов трения. Снижение энергонагруженности тормозных дисков является важной пробле- мой, что и нашло отражение в материалах настоящей статьи |
