(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.

發(fā)動機起動系統(tǒng)提供引氣、燃油、點火及扭矩，以使發(fā)動機轉(zhuǎn)動并加速到慢車所需的轉(zhuǎn)速。系統(tǒng)包括起動器、起動活門、起動引起活門、增壓管道、控制及電源線路，起動手柄及起動選擇開關。起動活門及起動器安裝于發(fā)動機附件齒輪箱，起動引氣活門安裝于高壓壓氣機左側 11點鐘位置，起動手柄、起動選擇開關及起動活門打開指示燈位于駕駛艙。發(fā)動機起動過程通過發(fā)動機增壓系統(tǒng)提供空氣經(jīng)過起動活門給起動器來完成。

(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
