This so called PPT for propulsion study for Shenyang Aerospace University. This PPT right protected by Dr. divinder K. Yadav. Its using in SAU by Lale. For all students of Aeronautical Engineering must memorize each & every words from this PPT. If you miss a single words you must fail in the Exam. Remember there is no chance to be creative or use sense you just need to use the power of memorizing.

3. Engine Starting System
Light aircraft use a direct-cranking electric starter
system. This system consists of a source of:
• Electricity
• Wiring
• Switches
• Solenoids to operate the starter
• Starter motor.

5. Engine Starting System
Aircraft have starters that automatically engage and disengage
when operated.
The starter engages to the crankshaft by gearing mechanism,
rotating the engine at a speed that allows the engine to start
and maintain operation.
Electrical power for starting is usually supplied by an
on-board battery, but can also be supplied by external
power through an external power receptacle.
The starter motor is protected from being driven by the engine
through a clutch in the starter drive that allows the engine to
run faster than the starter motor.

Precautions while starting the Engine:
• Make sure there is no one near the propeller.
• Wheels should be chocked and the brakes set, to avoid hazards
caused by unintentional movement.
• Airplane should be in an area where the propeller will not stir
up gravel or dust.
• Place fire extinguisher in the vicinity of aircraft
