outline gas turbine engines Flashcards
What is newtons third law
For every action there is an equal and opposite reaction
What is the relationship between newtons third law and jet propulsion
Applied by accelerating air through an orifice/nozzle. The acceleration is the action and forward movement is the reaction
Describe the braton cycle
open and continuous
What is the relationship between pressure, volume and density of gas
Gas volume, gas temperature and gas pressure can be combined to give the equation known as the general gas law.
Pressure x volume = amount of substance, ideal gas constant, temperature
What is jet reaction
For every action there is a equal and opposite reaction.
The force of the jet takes place at the exhaust and it tends to recoil in the opposite direction to creating thrust
What in a converging duct
The duct comes together
Velocity increase
Pressure decrease
Temperature decrease
What is a diverging duct
The duct goes apart
Velocity decrease
Pressure increase
Temperature increase
How is thrust calculated
Determine the difference between the airspeed of intake and exhaust
Compare it against a constant (gravity)
