    Analysis of the stress-deformed stateof the aircraft flap
    (КПІ ім. Ігоря Сікорського, 2024) Trubachev, S. I.; Alexeychuck, O. N .; Kryvova, S. G.
    Aircraft flaps play an important role in the operation of the aircraft. They are used to increase the lifting force of the aircraft at a given speed, which allows for slower take-off and landing. By increasing the camber of the wing, the flaps provide additional lift, which is especially useful during takeoff and landing when the air-craft needs to maintain control at low speeds. In addition, flaps also help increase the drag of the aircraft, which slows it down during landing. The flaps have a com-plex geometric shape, and therefore, to assess their stress-strain state, it is necessary to use numerical methods, primarily the finite element method. In the work based on the method of finite elements, there were determinations of stress under real op-erating loads. The proposed method makes it possible to carry out both verification calculations during design and optimization of the massof the aircraft flap.

    The strength calculation of the transport aircraft control system element by the finite element method
    (КПІ ім. Ігоря Сікорського, 2023) Trubachev, S. I.; Alexeychuck, O. М.; Kryvova, S. G.
    The work is devoted to determining the stress-strain state of the element of the control system of the transport aircraft, which serves to transmit motion and is an element of the mechanism for deflecting the rudder and removing the load from the control wiring. If this element is destroyed, the control system will not function, as a result of which some elements of the electronic installation of the aircraft will be disabled. Analytical methods are not always effective when studying the stress state of complex parts and mechanisms of aircraft construction, although they are also used. To determine the stress-strain state in the work, a numerical method was used - the finite element method, which models the stress-strain state of mechanical systems with great accuracy, taking into account the boundary conditions and the given load. A four-node tetrahedral element was chosen as a finite element. Based on the analysis of the stress-strain state, dangerous places in the structure were identified, where there is a possibility of a crack appearing and, as a consequence, destruction.
