The technology used builds on the highly successful DataChief C20KChief 500 marine automation system Back in 1967 we developed the XWRKLHI573475735957347WKH5734757535UVW57347UHPRWH57347FRQWURO system for low speed propulsion plants By 2013 more than SHAFT HORSEPOWER (S.H.P.) The total work of the turboprop gas turbine engine is taken out as shaft horsepower (S.H.P.) to drive the propeller rather than as tkinetic energy of the accelerated air expe Propulsion System. A machine that produces thrust to push an object forward. The amount of thrust depends on the mass flow through the engine and the exit velocity of the gas. Airplane Propulsion Systems.
