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(dòng)機(jī)起動(dòng)系統(tǒng)提供引氣、燃油、點(diǎn)火及扭矩，以使發(fā)動(dòng)機(jī)轉(zhuǎn)動(dòng)并加速到慢車(chē)所需的轉(zhuǎn)速。系統(tǒng)包括起動(dòng)器、起動(dòng)活門(mén)、起動(dòng)引起活門(mén)、增壓管道、控制及電源線(xiàn)路，起動(dòng)手柄及起動(dòng)選擇開(kāi)關(guān)。起動(dòng)活門(mén)及起動(dòng)器安裝于發(fā)動(dòng)機(jī)附件齒輪箱，起動(dòng)引氣活門(mén)安裝于高壓壓氣機(jī)左側(cè) 11點(diǎn)鐘位置，起動(dòng)手柄、起動(dòng)選擇開(kāi)關(guān)及起動(dòng)活門(mén)打開(kāi)指示燈位于駕駛艙。發(fā)動(dòng)機(jī)起動(dòng)過(guò)程通過(guò)發(fā)動(dòng)機(jī)增壓系統(tǒng)提供空氣經(jīng)過(guò)起動(dòng)活門(mén)給起動(dòng)器來(lái)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 |
