ФАКТОРИ ЗАБЕЗПЕЧЕННЯ НАДІЙНОЇ РОБОТИ ЗАКРИЛКІВ ЛІТАКІВ ТРАНСПОРТНОЇ КАТЕГОРІЇ

The paper analyses the measures to ensure reliable operation of flaps and the flap control system of transport category aircraft. A number of catastrophes, which were largely caused by flaps, are analysed. Specific requirements for flaps and its control system to ensure their trouble-free operation are considered. The main factors that are taken into account to ensure the safety of the flap control system are presented. The advantages created by wing mechanisation are considered. The AN-140 flaps are presented, with flap supports made with duplication of critical elements to ensure reliable operation. The parameters of the elements are chosen from the condition that each of the two elements must withstand the normalised operational load in case of complete destruction of one of them. The flaps and their control system of the AN-148 aircraft are considered. A new concept of aircraft control is presented, the essence of which is the development and creation of a control system powered by two hydraulic systems and two centralised electrical systems.
