on a brushless alternator? -
<<ANSWER>>Permanent magnets are installed in
the main field poles.
One way that the automatic ignition relight systems
are activated on gas turbine engines is by a -
<<ANSWER>>drop in compressor discharge
pressure.
How are the rotor windings of an aircraft alternator
usually excited? - <<ANSWER>>By a variable direct
current.
What precaution is usually taken to prevent
electrolyte from freezing in a lead acid battery? -
<<ANSWER>>Keep the battery fully charged.
, What is the ampere-hour rating of a storage battery
that is designed to deliver 45 amperes for 2.5 hours?
- <<ANSWER>>112.5 ampere-hour.
How many hours will a 140 ampere-hour battery
deliver 15 amperes? - <<ANSWER>>9.33 hours.
What is a basic advantage of using ac for electrical
power for a large aircraft? - <<ANSWER>>AC
systems operate at higher voltage than dc systems
and therefore use less current and can use smaller
and lighter weight wiring.
What are two types of ac motors that are used to
produce a relatively high torque? -
<<ANSWER>>Three-phase induction and capacitor
start.
(1) Alternators are rated in volt-amps, which is a
measure of the apparent power being produced by
the generator.
(2) Alternating current has the advantage over direct
current in that its voltage and current can easily be
stepped up or down.
Regarding the above statements, -
<<ANSWER>>both No. 1 and No. 2 are true.
