Abstract
<p>The relevance of this study is predetermined by the improvement to the fuel efficiency of an aircraft and, as a consequence, by the reduced cost of the life cycle of an aircraft engine, which is part of a power assembly at the training aircraft the type of DART-450. We have theoretically substantiated the flight-technical and economic characteristics of a modern light aircraft for training flying personnel. Underlying the research methods is a set of parameters, characteristics and indicators, which generally reflect the technical-economic perfection of engine in the powerplant of the technical system «powerplant ‒ airframe» at a light training aircraft.</p><p>The scientific novelty of this research is in the formation of a new parametric shape of a turboprop engine for the powerplant of a light training aircraft the type of DART-450, taking into consideration the modeling of the predefined flight cycle of an aircraft and the life cycle of the engine.</p><p>Numerical study has established that the maximum flight range of aircraft with different engines at the same takeoff weight is largely determined by a fuel reserve, rather than the efficiency of fuel consumption. Therefore, an engine with the lowest capacity has the advantage in all characteristics except for a takeoff distance, which is the shortest for an aircraft with the engine of maximum power.</p>The results have substantiated that in order to perform tasks related to training flight personnel it is appropriate to install the engine AI-450SR, which has the lowest life cycle cost. It is obvious that a given aircraft with the installed engine will have the lowest cost per flight hour. However, to perform reconnaissance and strike missions at an aircraft the type of DART-450, it is advisable to install the engine AI-450SR. To perform only the strike missions at an aircraft the type of DART-450, it is expedient to install the engine MS-500V-S, which has more power than the considered motors
