Review of basic incompressible and compressible flows, introduction to oblique shock waves, PrandtlMeyer flows. Detailed airfoil analyses including effects on lift and drag of angle of attack, Reynolds number, compressibility. Three-dimensional considerations: qualitative discussion of down-wash and circulation, quantitative aspects of this type of flow. Boundary layer theory: simple ideas, flat plate flows, calculation formulae.
Review of fluid mechanics principles including shock wave. Details of air-breathing propulsion including analysis of diffusers and nozzles, compressors and turbines, and combustion processes. Matching of components is treated in depth. Over-all vehicle analysis treating turbojet, turbofans, turboprops, ram-jets.
Actual optimum design of an airplane meeting the specifications of load (number of passengers and/or weight of cargo), range, field length, and cruising speed. The course proceeds step by step to calculate all the design characteristics: wing sweepback, thickness ration, wing loading, thrust loading, takeoff weight, drag, range, direct operating cost. Many of these factors are varied in order to optimize the cost. Students will work in multidisciplinary teams to prepare proposals to perform preliminary design of a jet transport that will draw significantly on knowledge and skills acquired in previous coursework.
A specific field of design will be selected. The design will be open-ended and proceed from specifications using all the pertinent fields of science and engineering as well as empirical formulations. Some topics which may be selected are Supersonic Aircraft, Rocket Technology and Helicopter Design.
