Flashcards on Gas Turbine Engine Fundamentals

Rocket Engine

A non-air-breathing engine that carries its own oxidizer and fuel, allowing it to operate outside the Earth's atmosphere.

Ramjet

The simplest form of power plant that uses the atmosphere to sustain combustion, with no moving parts.

Pulsejet

An air-breathing jet engine without a compressor or turbine, where intermittent combustion provides the thrust.

Scramjet

A variation of a ramjet that has supersonic combustion.

Gas Turbine Engine

Includes an air inlet, compressor, combustion section, turbine section, and exhaust section; can be turbojet, turbofan, turboprop, or turboshaft.

Newton's First Law (Law of Inertia)

States that a body at rest remains at rest, and a body in motion continues to move at a constant velocity unless acted upon by an unbalanced external force.

Newton's Second Law

States that the net or unbalanced force acting on an object equals the mass of the object times the acceleration of that object (F = ma).

Newton's Third Law (Law of Action and Reaction)

States that when one object exerts a force on a second object, the second must exert an equal and oppositely directed force on the first.

Entropy

A quantitative measure of the amount of thermal energy not available to do work in a closed system.

Zeroth Law of Thermodynamics

Establishes temperature as a fundamental and measurable property of matter.

First Law of Thermodynamics

States that the total increase in the energy of a system is equal to the increase in thermal energy plus the work done on the system.

Second Law of Thermodynamics

States that heat energy cannot be transferred from a body at a lower temperature to a body at a higher temperature without the addition of energy.

Third Law of Thermodynamics

States that the entropy of a pure crystal at absolute zero is zero.

Adiabatic Process

A process with no heat transfer into or out of a system.

Isochoric Process

A constant-volume process.

Isobaric Process

A constant-pressure process.

Isothermal Process

A constant-temperature process.

Internal Energy

Is the sum of the kinetic and potential energies in a gas.

Isentropic Process

A process in which entropy remains constant; it is adiabatic and reversible.

Heat of Combustion

The total energy released as heat when a substance undergoes complete combustion with oxygen under standard conditions.
