СИНЕРГЕТИЧЕСКИЙ СИНТЕЗ АВТОПИЛОТА ДЛЯ УПРАВЛЕНИЯ ДВИЖЕНИЕМ САМОЛЕТА-АМФИБИИ БЕ-200 ВО ВРЕМЯ ЗАБОРА ВОДЫ

Abstract

The article is devoted to solving the problem of controlling the Be-200 amphibious aircraft whentaking water in the gliding mode. The specified mode of flight of an amphibious aircraft (AA) is one ofthe most intense for piloting. Controlling an aircraft in gliding mode requires the highest concentrationfrom the pilot, since the hydrodynamic characteristics decrease, but the aerodynamic ones increase,which causes situations in which the SA becomes uncontrollable. To ensure the safe operation of the AAduring water intake, as well as to ensure a steady takeoff, the pilot is forced to constantly maintain acertain value of speed, trim angle, and engine thrust by moving the engine control stick (ECS). In thisregard, it seems very appropriate to use the technical means of the autopilot, which provides control ofthe speed, engine thrust and trim angle to ensure the stability of the movement of the SA during the intakeof water. The article deals with the problem of synthesizing an autopilot to control the movement ofan amphibian aircraft during water intake, and at the same time the following tasks are solved: thesynthesis of an autopilot to control the longitudinal movement of an amphibian aircraft, as well as controllanding on water, followed by water intake and takeoff from the water. The substantiation of thechoice of a mathematical model of the movement of an aircraft on water is given. A procedure for thesynergistic synthesis of the autopilot controller of an amphibious aircraft in the water intake mode presented.The novelty of the ongoing research lies not only in considering the stable movement of an amphibiousaircraft during its operation on the water surface, but also in modeling the process of water intake in planning mode, which is a more complex task from the point of view of synthesis. As a result,the control laws for the autopilot obtained, which ensure the stable movement of the amphibious aircraftwhen descending along the glide path, landing on water, taking in water and subsequent takeoff withdamping of longitudinal oscillations along the trim angle throughout the entire water intake cycle.
