Civil War commanders were trained in the Napoleonic art of war, and attempted on the battlefield to execute the basic principles of warfare as outlined by Jomini. Despite the best plans and executions of strategy and tactics, frictions in war, as discussed by von Clausewitz, tend to disrupt preparations and affect battle outcomes. The south Louisiana 1862 Battle of Labadieville serves as an ideal case study for fostering this thesis.展开更多

At first, a short description of previous "generations" of jet fighter is given, introducing the interest that has always been originated by the concept of"light fighter" for every of the first four fighter generations. The derivation of the first idea of a new 5th generation light fighter is then described. Then to further investigate the feasibility of idea, a conceptual design study has been driven up by utilizing peculiar tools, both for quantitative and qualitative (i.e., the aircraft layout definition) evaluations.
