TEXT
[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.
[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 the ignition system is to produce a high current electrical
spark to ignite the fuel/air mixture in the engine combustion chamber during
starting and to provide continuons ignition during takeoff, landing and operation in
