Impulse efficiency
http://www.impulsepower.com/ WitrynaOptimized results for single stage turbines, with different V r and a fixed SP equal to 0.05, are presented in Fig. 9.7.The breakdown of efficiency losses shows that the maximum attainable efficiency is a decreasing function of V r.For really low volume ratios, namely values below about 2, 7, velocity triangles are subsonic, the load is limited and 50% …

Reaction turbines develop torque by reacting to the gas or fluid's pressure or mass. The pressure of the gas or fluid changes as it passes through the turbine rotor blades. A pressure casement is needed to contain the working fluid as it ...
Witryna29 kwi 2024 · $\begingroup$ Similarly to jet engines, matching the exhaust speed and the vehicle speed gives optimum efficiency, in theory. However, in practice, this results in a very low specific impulse, causing much greater losses due to the need for exponentially larger masses of propellant.
