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.

Since the introduction of the first operational turbojet engine some 50 years ago by Frank Whittle and his team in Great Britain, the engines have become bigger and bigger to meet the demands of high fuel efficiency and specific thrust.
Three specific thrusts are proposed to predict the role of solute chemistry on : (i) fundamental dislocation phenomena, and the resulting effects on plastic flow and ductility (Solute/Dislocation/Dislocation interactions); (ii) dislocation transmission/absorption and damage nucleation along boundaries (Solute/Grain-boundary/Dislocation interactions); and (iii) the propagation of cracks under monotonic and fatigue loading (Solute/Crack/Dislocation/Grain-boundary interactions).
