Description: The method of estimation of influence of mass, geometrical and aerodynamic characteristics of aviation decimators on flowing characteristics of engine of power-plant of battle aircraft is developed. The offered scientifically-methodical vehicle will allow on the stages of the preliminary planning of airplane-hedge-hopper to conduct the ground of directions modernization of complex a “glider – a power-plant – aviation decimators”. In basis of method the mathematical design of the flow dynamics flowing around of different aviation decimators is utillized with the use of heuristic and retrospective methods, experimental information. The ground of testtactical and operating characteristics of battle airplane is conducted by research of typical flight cycle.
Keywords: battle aircraft, hedge-hopper, aircraft, aviation decimators, aviation engine, power-plant, self-reactance look, technical and economic efficiency, test-tactical characteristics
