Block 2 Powerplants Flashcards
What are some hazards of the Engine Inlet Suction Area?
Getting too close to a running engine inlet could result in serious injury or damage to equipment
What are some hazards of the Engine exhaust area?
When the engines are running the force and heat extends far behind the aircraft which could blow over individuals and vehicles on the flight line, causing injury or damage
What are the Anti-collision lights used for?
They are located on the top and bottom of the aircraft and should be flashing while the engines are running.
What type of engines is the p8 powered by?
Two CFM56-7B engines
What characteristics does the engines have and how much thrust are they capable of?
A high bypass, dual rotor, axial flow Turbofan engine producing 27,300 lbs of thrust
Describe the purpose of the High pressure compressor
The HPC is a 9 stage compressor that sends compressed air to the combustor as well as supplies bleed air for aircraft pneumatic systems.
Describe the purpose of the fan and booster?
It is a 4 stage compressor. The fan is the 1st stage and the booster is a 3 stage compressor. The fan increases the speed of the air.
Where does the primary air flow go?
Into the core of the Engine and booster increases pressure and sends to the HPC
Where does the secondary air flow go?
Into the fan duct and it supplies approximately 80% of the thrust during takeoff
What are the 6 sections of the CFM56-7B?
1) Fan and Booster section
2) High Pressure Compressor
3) Combustor
4) High Pressure Turbine
5) Low Pressure Turbine
6) Accessory Drive
Describe the purpose of the Combuster?
The combustor section mixes air from the compressors and fuel from the fuel nozzles to make hot gases
What is the purpose of the High pressure turbine?
The HPT is a single stage turbine that converts the energy from the hot gases into mechanical energy to turn the HPC rotor and accessory drive.
What is the purpose of the Low pressure turbine?
The LPT is a 4 stage turbine that changes hot gases into mechanical energy to turn the fan and booster rotor.
What components make up the accessory drive?
Inlet Gear Box IGB Radial Drive Shaft RDS Transfer Gear Box TGB Horizontal Drive Shaft HDS Accessory Gear Box AGB
What is the purpose of the Auxiliary Power Unit?
Supplies bleed air for both air conditioning on the ground or in flight. It can supply electrical power for the airplane on the ground. It also provides pneumatic power (compresses air) for engine starting and for operating 2 air conditioning packs.
