Specific thrust — is a term used in Gas Turbine Engineering to show the relative bulk of a jet engine (e.g. turbojet, turbofan, etc) and is defined as the ratio: net thrust/total intake airflow. Low specific thrust enginesA modern civil turbofan has a low specific … Wikipedia
specific thrust — The ratio of total thrust produced by an engine and the mass of the engine. It is a measure of the efficiency of the engine. It is 1/specific weight of engine … Aviation dictionary
Specific impulse — (usually abbreviated I sp) is a way to describe the efficiency of rocket and jet engines. It represents the impulse (change in momentum) per unit of propellant. The higher the specific impulse, the less propellant is needed to gain a given amount … Wikipedia
Thrust bearing — A thrust bearing is a particular type of rotary bearing. Like other rotary bearings they permit rotation between parts, but they are designed to support a high axial load while doing this.Thrust bearings come in several varieties. * Ball thrust… … Wikipedia
Specific fuel consumption (thrust) — Specific fuel consumption, often shortened to SFC, or TSFC is an engineering term that is used to describe the fuel efficiency of an engine design with respect to thrust output. It allows the efficiency of different sized engines to be directly… … Wikipedia
Specific orbital energy — In the gravitational two body problem, the specific orbital energy (or vis viva energy) of two orbiting bodies is the constant sum of their mutual potential energy ( ) and their total kinetic energy ( ), divided by the reduced mass. According to… … Wikipedia

specific impulse — noun Date: 1947 the thrust produced per unit rate of consumption of the propellant that is usually expressed in pounds of thrust per pound of propellant used per second and that is a measure of the efficiency of a rocket engine … New Collegiate Dictionary
thrust-specific fuel consumption — A measure of the fuel efficiency of a turbojet or turbofan engine. It is the mass of fuel burned per hour for each unit of thrust produced … Aviation dictionary
specific impulse — Rocketry. 1. a measure, usually in seconds, of the efficiency with which a rocket engine utilizes its propellants, equal to the number of pounds of thrust produced per pound of propellant burned per second. 2. the specific impulse that a given… … Universalium
