NettetSide by side with the development of linearized supersonic theory and largely independent of it, there has also been an extensive study of the diffraction of harmonic electromagnetic waves, and of sound waves and pulses, by variously shaped obstacles. Accounts of the developments in these fields have been given by Friedlander (1958) … NettetLinearized supersonic aerofoil theory is developed by operational methods. It is shown that a wide variety of problems can be handled by these methods, which have the advantage of very directly exhibiting the analogies between supersonic aerofoil and other wave problems.

NettetThe wings in compressible flow, such as transonic flow, subcritical flow, supersonic linearized theory, and other aspects of supersonic wings are discussed in this chapter. The analysis of this regime involves solving a set of nonlinear differential equations, a task that demands either advanced computational techniques or some form of approximation.
