AMT 2101 Reviewer Flashcards
It consist of magnetic circuit consists of a permanent multi-pole rotating magnet, a soft iron core, and pole shoes
Magneto Circuit
Low-voltage is generated in the magneto and flows to the primary winding of a transformer coil located near the spark plug.
Low Tension Magneto
A magnetic field consists of invisible lines called
Lines of magnetic flux
If a conductor is moved through the lines of magnetic flux that pass between the poles of a magnet, a flow of electrons is induced in the conductor. This is called _______
Electro Magnetic Inductor
The magnetic circuit consists of a permanent multi-pole rotating magnet, a soft iron core, and ____
Pole Shoe
Before a spark plug can be removed, the ignition harness lead must be_____
Disconnected
Flange-mounted magnetos are attached to the engine by a flange around the driven end of the rotating shaft of the magneto.
Magneto mounting system
The number of lines of flux that loop through a magnet is an indication of a magnet’s strength. One line of flux is called one.
Maxwell
What is the meaning of EMF?
Electromotive Force
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.
Inertia Starter
The measure of ease with which lines of flux travel through a material is referred to as a material
Permeability
The ______consists of a set of breaker contact points, a condenser, and an insulated coil.
Primary electrical circuit
Spark plugs should be removed for inspection and servicing at the intervals recommended by the____
Manufacturer
One rotating magnet and a cam are common to two sets of breaker points and coils. Two separate distributor units are mounted in the magneto
Single and Dual high tension system magneto
The South poles magnet is labeled as___
S
Consists of two brushes, two brush springs, and brush holders.
Rotor
It contains the ignition harness contains an insulated wire for each cylinder that the magneto serves in the engine.
Ignition Harness
It is any piece of equipment that converts mechanical energy into electrical energy by electromagnetic induction.
Generator
It is one way to determine the direction of the induced EMF.
Left hand rule
As the rotor turns, the load current is induced into stationary stator coils
Starter
The magneto generates electrical power by the engine rotating the permanent magnet and inducing a current to flow in the ____
Coil Winding
The circuit contains the secondary windings of the coil, distributor rotor, distributor cap, ignition lead, and spark plug
Secondary electrical circuit
TYPES OF AIRCRFAFT STARTER
1.Inertia
2.Direct hand cranking
3.Pullcord
4.Coffman
5.Electrical
6.Pneumatic
7.DC electric motor
8.Starter generator
Two ways to complete the primary circuit
1.Through close breaker points to ground.
2.Through close ignition switch to ground.
In the inertia starter, energy is stored slowly during an energizing process by a manual hand crank or electrically with a small motor.
TRUE
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.
FALSE
If the starter turns the turbine engine up to a self-sustaining speed, the engine start process will not be successful.
TRUE
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
