Topology optimization and finite element analysis of a jet dragster engine mount
Cogent Engineering, 2020 In a jet dragster race car, the engine mount is one of the important components of an engine sub-assembly. The mounting system is the primary interface between the jet engine and the vehicle chassis, firmly containing the engine and transmitting forces ...

Simple Thermodynamics of Jet Engines [PDF]
American Journal of Physics, 2010 We use the first and second laws of thermodynamics to analyze the behavior of an ideal jet engine. Simple analytical expressions for the thermal efficiency, the overall efficiency, and the reduced thrust are derived. We show that the thermal efficiency depends only on the compression ratio r and on the velocity of the aircraft.
