- W2018568198 abstract "The standard but ill-defined concept of propulsive efficiency, classically employed in the analysis of turbojet and turbofan engines, can be approached from the point of view of energy utilization by applying basic thermodynamic principles. First and second law analysis of propulsive powerplants as general thermodynamic systems leads to a universal definition for propulsive efficiency. This definition clearly accounts for the energy unavailability production separated into two distinct parts: 1) the unavailable energy associated with the thermodynamic cycle's rejected heat; and 2) the wasted energy produced by inefficiencies inherent to the conversion of available cycle energy to propulsive power. As a result, conversion or transfer inefficiencies are consistently reflected in the propulsive efficiency, whereas cycle inefficiencies are most properly identified with cycle, or thermal, efficiency for a powerplant." @default.
