Powerplant & Propulsion
The starter in an turbine engine turns this component during engine start.
What is the compressor?
Increasing blade angle at constant RPM increases thrust because it increases this aerodynamic factor.
What is AOA?
These three things make a complete circuit.
What is a power source, load, and conductors.
This is routed to systems like anti-ice or cabin pressurization from the compressor section.
What is bleed air?
What are Fowler flaps?
What is the turbine wheel?
What is increase?
This type of voltage is always higher than battery voltage.
This type of ice protection prevents ice from forming on aircraft surfaces.
What are anti-ice systems?
These leading-edge devices extend to increase the wing's maximum lift and delay stall at low speeds.
What are slats?
Most of the air entering a turbine engine never sees combustion because it forms this critical function.
What is cooling?
What is blade pitch?
Increasing the amount of wire loops in the coil will directly increase this aspect of the electrical system.
What is current?
This aircraft system conditions and distributes air from the engines to keep the cabin comfortable and pressurized.
What is a PACK?
These components make up the pressure vessel.
This type of compressor is more durable but generally less aerodynamically efficient than axial designs.
What is a centrifugal compressor?
Feathering a propeller after engine failure reduces drag because the blades are aligned this way.
What is parallel to the relative wind?
This type of fault occurs when the system won't operate because it is receiving an incorrect control signal.
What is a logic fault?
These small devices are installed in engine inlets or wings to redirect airflow and prevent ice from forming in critical areas.
What are ice vanes?
This is where P3 air is drawn off of.
What is the compressor.
As altitude increases, maintaining the same power setting becomes harder because temperature and RPM limits restrict this performance margin.
What is excess thrust?
In a non-counterweight constant-speed propeller, the blades move toward a lower pitch to increase RPM by increasing oil pressure and this aerodynamic effect.
What is aerodynamic twisting force?
Aircraft alternators generate AC, but the onboard systems require DC, so this component is used to allow current to flow in only one direction.
What are diodes?
This system automatically extends leading-edge surfaces if the angle of attack becomes dangerously high, helping prevent a stall.
What is the Auto Slat Stall Protection System?
This part spins the compressor.
