Two separate systems are needed to make sure that a turbine engine can begin satisfactorily. Firstly, provision should be created for the mechanical device and rotary engine to be revolved up to a speed at that adequate air passes into the combustion system to combine with fuel from the fuel spray nozzles (Part 10).
Secondly, provision should be created for ignition of the air/fuel mixture within the combustion system. throughout engine beginning the 2 systems should operate at the same time,
yet it should even be attainable to motor the engine over while not ignition for maintenance checks and to control solely the ignition for relighting throughout flight (para. 28).

2. The functioning of each systems is co-ordinates throughout a beginning cycle associate degreed their operation is mechanically controlled when the initiation of the cycle by an circuit. A typical sequence of events throughout the beginning of a turbo-jet engine is shown in fig. 11-1. METHODS OF beginning licensed aircraft engineer.

3. The beginning procedure for all jet engines is essentially the identical, however may be achieved by varied strategies. the kind and power supply for the starter varies in accordance with engine and craft needs licensed aircraft engineer.
Some use wattage, others use gas, air or hydraulic pressure, and every has its own deserves. as an example, a military craft needs the engine to be started within the minimum time and, once attainable, to be fully freelance of external instrumentation. a billboard craft, however, needs the engine to be started with the minimum disturbance to the passengers and by the foremost economical means that. Whichever system is employed, responsibility is of prime importance licensed aircraft engineer.
4. The starter should turn out a high torsion and transmit it to the engine rotating assembly during a manner that gives swish acceleration from rest up to a speed at that the gas flow through the engine provides ample power for the engine rotary engine to require over licensed aircraft engineer.


5. the electrical starter is sometimes an on the spot current (D.C.) motor coupled to the engine through a discount gear and ratchet mechanism, or clutch, that mechanically disengages when the engine has reached a self-sufficing speed (fig. 11-2) licensed aircraft engineer.

6. The electrical provide could also be of a high or low voltage and is gone through a system of relays and resistances to permit the complete voltage to be increasingly designed up because the starter gains speed. It additionally provides the ability for the operation of the ignition. The electrical provide is mechanically off once the starter load is reduced when the engine has satisfactorily started or when the time cycle is completed. A typical electrical beginning system is shown in fig. 11-3 licensed aircraft engineer.
