PREFACE
The task of up–to–date aircraft designing includes extensive com-plex of related problems. It is necessary to satisfy the requirements of aerodynamics and flight dynamics, strength and stiffness, reliability and survivability, repairability and, the main, effectiveness. Recently, different versions of economic efficiency criterion are frequently used as the main optimization criterion both for civil and military aircraft.
A number of factors directly effecting on economic efficiency of created or operated aircraft are related to power plant designing solutions. Rational choice of type and number of engines, their model and arrangement on aircraft significantly effects on following all main requirements to the designed aircraft and of-
ten even to realizability of new aircraft (e. g. vertical/short take-off and landing (VTOL/STOL) aircraft, stealth
aircraft and micro aviation aircraft).
Engine mount scheme selection rationality and its parameters choice correctness impact not only to strength and stiffness, but also allow to eliminate resonance, discomfort condition for passengers onboard, increased
crew fatigability, fast equipment wear; provide maintainability and repairability; and as a result impact to profit
brought by aircraft and its competitiveness. Fuel system designing quality directly impacts to reliability and
fire danger of power plant, direct and indirect aircraft maintenance expenses, for example, due to greater or less mass of unusable fuel, required fuelling time etc. Air intake designing significantly impacts to aircraft
aerodynamic performance, engine efficiency, unprepared airfield basingcapability, aircraft maneuverability...
Therefore, great attention is paid to studying the course «Airplane Power Plant
System Designing», its full and up–to–date methodical support.
This publication contains the synop sis for the lecture course «Airplane Power Plant System Designing», which is taught for the fourth course students, being studying for the major subject «Aerospace Engineering». The synopsis includes 11 themes, which are intended to powerplant arrangement and classification, engine mount and its shock absorption, fuel and lubricant systems, internal aerodynamics, subsonic and supersonic air intakes designing, exhaust units and power plants outlook.
With the brevity purpose, we use two techniques within this synopsis: when the difference is insufficient, instead «turbojet and bypass turbojet» we write «(bypass) turbojet»; and we use «[+]» sign to mark advan-
tage and «[–]» sign to mark disadvantage correspondingly. This synopsis can be useful for the fullest understanding of information given at lectures for students independent studying of some ques-
tions, when preparing to laboratory work passing, when doing course and diploma projects and also bachelor papers.
