Q

A type of starter with a kinetic energy is energy possessed by a body by virtue of its state of motion, which may be movement along a line or spinning action. In the inertia starter, energy is stored slowly during an energizing process by a manual hand crank or electrically with a small motor.

17
Q

Is a method of starting an internal combustion engine , usually on small machines, such as lawn
mowers chainsaws ultralight aircraft , small outboard motors and portable engine generators

A

Pullcord starter

18
Q

It can be divided into three distinct circuits: magnetic, primary electrical, and secondary electrical circuits

A

High tension magneto

19
Q

Also Known as Coffman starter

A

shotgun starter

20
Q

An alternator rotor consists of a wire coil wound on an iron spool between two heavy iron segments with interlacing fingers.

A

rotor

21
Q

It is an aircraft magneto that incorporates a single drive source powering two magnetos.

A

dual

22
Q

contains an insulated wire for each cylinder that the magneto serves in the engine.

A

Ignition harness

23
Q

It is any piece of equipment that converts mechanical energy into electrical energy by electromagnetic induction.

A

generator

24
Q

It is one way to determine the direction of the induced EMF.

A

Left hand rule

25
Q

As the rotor turns, the load current is induced into stationary stator coils

A

starter

26
Q

The magneto generates electrical power by the engine rotating the permanent magnet and inducing a current to flow in the

A

coil winding

27
Q

The circuit contains the secondary windings of the coil, distributor rotor, distributor cap, ignition lead, and spark plug

A

secondary electrical circuit

28
Q

TYPES OF AIRCRFAFT STARTER

A

Inertia
Direct hand cranking
Pullcord
Coffman
Electrical
Pneumatic
DC electric motor
Starter generator

29
Q

two ways to complete the primary circuit

A

Through close breaker points to ground
Through close ignition switch to ground

30
Q

In the inertia starter, energy is stored slowly during an energizing process by a manual hand crank or electrically with a small motor.
(TRUE OR FALSE)

A

TRUE

31
Q

The starter must turn the engine up to a speed that provides enough electricity through the engine for fuel to be ignited. Then, the starter must continue to help the engine accelerate to a self sustaining speed. Turbine engine starters have a critical role in starting of the engine. (TRUE OR FLASE)

A

FALSE

32
Q

If the starter turns the turbine engine up to a self sustaining speed, the engine start process will not be successful. (TRUE OR FALSE)

A

TRUE

33
Q

A starter is an electromechanical mechanism capable of developing large amounts of mechanical energy that can be applied to an engine, causing it to rotate. Reciprocating engines need only to be turned through at a relatively slow speed until the engine starts and turns on its own. (TRUE OR FALSE)

A

TRUE
