In this paper, a comparison between entropy generation minimization method and the efficiency & lifetime maximization technique of the turbogenerator/plane is presented. The paper reviews the concept of irreversibility, entropy generation or energy destruction applied to the lubrication system and elasto hydrodynamic lubricated bearings used in the turbogenerator and fuel/hydraulic system of the plane. Our way to express the entropy law in the power engineering and aviation is that in a lubrication system of the turbogenerator and fuel/hydraulic system of the plane subsystem tend to disintegrate over time. The break, break down, break up, chemical reactions, gas and water production, rust, die decay, wear out and generally move from a state of higher organisation to one of lower organisation, from order to disorder. Moreover, the entropy generation rate vs. efficiency & lifetime behaviour of the turbogenerator/plane reveals that the efficiency & lifetime at minimum entropy generation rate and the maximum efficiency & lifetime are distinct.
