15.1 Fundamentals Flashcards
Newton’s first law denotes what?
A body at rest will remain at rest and a body at motion continues to move at motion until acted upon by an external force
Equation for Newton’s second law?
Force=Mass x Acceleration
4 stages of an engine?
- Intake (Suck)
- Air compression (squeeze)
- Combustion (Bang)
- Expansion/Exhaust (Blow)
Newton’s third law denotes what?
Every action has a equal and opposite reaction
Within the compressor does the static pressure?
A- Increase
B- Decrease
C- Stay the same
A- Increase
The process of adding heat into the compressor at a constant pressure is known as what?
Isobaric Heating
What is the main function of an engine?
Provide thrust
Apart from thrust, what are three other functions of aircraft engines?
Supply hydraulic power
Supply electrical power
Supply bleed air for pneumatic systems
An engine which uses jet propulsion can also be known as what?
A reaction engine
Performance of piston engines decrease when and why?
Decrease at high altitude due to there being less airflow/dynamic pressure
To accelerate air, air pressure must what?
Increase
All gas not used to drive compressor, does what?
Used as thrust
Turboprop engines produce the majority of their thrust how?
Small acceleration of a large quantity of air with a propeller
Turboprop engines convert all gas energy to what?
Torque
Compressors are made up of what?
Rotors and stators
