Day 1 Progress Check Flashcards
What is the function of the wobble plate in a constant speed drive (CSD)?
It controls the speed of the hydraulic motor
What happens when a CSD or IDG malfunctions in-flight?
It disconnects automatically and cannot be reconnected in-flight
Why is frequency control critical in aircraft electrical systems?
It affects the operation of frequency-sensitive components
What is the primary benefit of a wye-wound three-phase connection?
More voltage potential
Which phase connection provides the possibility of having two voltage levels from one generator?
Wye-Wound three-phase connection
Why are Integrated Drive Generators (IDGs) generally not field-repairable?
They are high speed and oil-cooled
How many single-phase windings does a three-phase generator have?
Three
Which component combines both a constant speed drive (CSD) and a generator into a single unit?
Integrated Drive Generator (IDG)
Which method of field excitation is used in a DC exciter within an AC generator system?
Generator inside of a generator
What is the standard frequency for aircraft AC generators?
400 Hz
How does a Constant Speed Drive (CSD) maintain a constant output speed despite variable input speed?
By adjusting the angle of the pump wobble plate
Which type of rotor and stator configuration is most common and efficient in AC generators?
Rotating field & stationary armature
What role does a constant speed drive (CSD) play in an aircraft?
It maintains a constant generator speed
In a delta-wound three-phase generator, how are the phase legs connected?
In parallel
What is the primary electrical power source in large aircraft?
Alternating Current (AC)
