Turboréacteur Flashcards
What is a turboréacteur?
A turboréacteur is a type of jet engine that converts fuel into thrust using a turbine.
True or False: A turboréacteur works on the principle of jet propulsion.
True
What are the main components of a turboréacteur?
The main components are the compressor, combustion chamber, turbine, and nozzle.
Fill in the blank: The __________ compresses incoming air in a turboréacteur.
compressor
What is the function of the combustion chamber in a turboréacteur?
The combustion chamber burns fuel to create high-temperature, high-pressure gas.
Multiple Choice: Which component of the turboréacteur is responsible for extracting energy from the exhaust gases?
Turbine
What role does the nozzle play in a turboréacteur?
The nozzle accelerates the exhaust gases to produce thrust.
True or False: A turboréacteur can operate efficiently at low speeds.
False
What is the primary advantage of a turboréacteur over a piston engine?
Higher speed and efficiency at high altitudes.
Fill in the blank: The __________ is used to increase the pressure of the air before it enters the combustion chamber.
compressor
What is the typical fuel used in turboréacteurs?
Jet fuel, typically Jet A or Jet A-1.
Multiple Choice: Which type of aircraft predominantly uses turboréacteurs?
Commercial airliners
What is the Brayton cycle in relation to turboréacteurs?
The Brayton cycle describes the thermodynamic cycle of a turboréacteur.
True or False: Turboréacteurs have a higher thrust-to-weight ratio than turboprop engines.
True
What is afterburning in a turboréacteur?
Afterburning is a process that injects fuel into the exhaust stream to increase thrust.
Fill in the blank: A turboréacteur operates primarily based on the principles of __________.
thermodynamics
What is a key disadvantage of using turboréacteurs?
They can be less efficient at low speeds compared to other engine types.
Multiple Choice: What is the primary purpose of the turbine in a turboréacteur?
To drive the compressor
What is the significance of bypass ratio in a turboréacteur?
Bypass ratio affects the engine’s efficiency and noise levels.
True or False: The efficiency of a turboréacteur decreases at higher altitudes.
False
What does the term ‘specific fuel consumption’ refer to in turboréacteurs?
It refers to the fuel efficiency of the engine, typically measured in pounds of fuel per hour per thrust produced.
Fill in the blank: The __________ converts the kinetic energy of the exhaust into thrust.
nozzle
What is a turbofan engine?
A turbofan engine is a type of turboréacteur that has a large fan at the front to improve efficiency.
Multiple Choice: Which of the following is NOT a component of a turboréacteur?
Propeller
What is the role of the air intake in a turboréacteur?
The air intake directs airflow into the compressor.
True or False: Turboréacteurs are commonly used in military aircraft.
True
