Measures of Engine Performance
Engine types vary greatly in a number of different ways:
- energy efficiency
- fuel/propellant consumption (brake specific fuel consumption for shaft engines, thrust specific fuel consumption for jet engines)
- power-to-weight ratio
- thrust to weight ratio
- Torque curves (for shaft engines) thrust lapse (jet engines)
- Compression ratio for piston engines, overall pressure ratio for jet engines and gas turbines

Famous quotes containing the words measures, engine and/or performance:
“The reliance on authority measures the decline of religion, the withdrawal of the soul.”
—Ralph Waldo Emerson (1803–1882)
“There is a small steam engine in his brain which not only sets the cerebral mass in motion, but keeps the owner in hot water.”

“When a book, any sort of book, reaches a certain intensity of artistic performance it becomes literature. That intensity may be a matter of style, situation, character, emotional tone, or idea, or half a dozen other things. It may also be a perfection of control over the movement of a story similar to the control a great pitcher has over the ball.”
—Raymond Chandler (1888–1959)
