(1) the engine starting system provides air, fuel, ignition and torque for rotating the engine to an rpm at which the engine can accelerate to idle rpm. The system consists of the starters, start valves, start bleed valves, pneumatic ducting, control and power circuitry, start levers and start selector switches. The start valve and starter are located on the forward side of the engine accessory gearbox, the start bleed valve is located on the left side of the HPC case at the 11 o’clock position, the start levers, start selector switches and start valve open light are in the flight compartment. Engine starting is accomplished by supplying air from the pneumatic system through the start valve to the starter.

发动机起动系统提供引气、燃油、点火及扭矩，以使发动机转动并加速到慢车所需的转速。系统包括起动器、起动活门、起动引起活门、增压管道、控制及电源线路，起动手柄及起动选择开关。起动活门及起动器安装于发动机附件齿轮箱，起动引气活门安装于高压压气机左侧 11点钟位置，起动手柄、起动选择开关及起动活门打开指示灯位于驾驶舱。发动机起动过程通过发动机增压系统提供空气经过起动活门给起动器来完成。

(2) The engine starter is a single-stage, axial flow, turbine-air motor, the starter converts compressed air pressure into rotational mechanical energy sufficient to accelerate the engine to starting speed. Pressurized air and electrical power are required for starter operation. The engine may be started with air from the APU(we will introduce APU in the next lesson), from a ground source, or by using engine crossbleed. Another important system related to engine operation is the ignition system. The purpose of
