　　AbstractThis book is intended to explain the purposes and general structures of the main members and systems of airplanes， to analyze the characteristics and the structural features of aircrafts， with accordance to airworthiness requirements. Also it is intended to describe the methodology for the designing and modifying of aircrafts， their units and systems， assembly units， with accordance to the requirements of airworthiness regulations. And it is intended to describe the purpose， layout and principal diagrams， operation and basic parameters， structure of assemblies and elements of systems of aircraft power plants with accordance to airworthiness. The emphasis is put on the operation of systems of aircraft power plants.It is shown that the classification of aircraft by aerodynamic configuration， a main units structure （as wing， fuselage， tail unit， landing gear， etc.）， general requirements to the units， the airworthiness requirements to units， the geometrical parameters of the units， advantages and disadvantages of different units configurations， load carry structures of units， structural members of units， etc.. And it is shown that the functionality， design features， arrangement， operational principles， methods of equipment design of aircraft power plant systems， which meet both general and specific requirements. The operation，structure design of aircraft power plant systems （engine selection， engine mount， systems： fuel， lubrication， air ingestion， exhaust， protection， electro mechanical， etc.） are presented in interaction with other components and systems of airplane.This book will be suitable for students majoring in airworthiness， designers， manufacturing engineers， etc.
