Figure 9: Prandtl-Meyer expansion fan 4.15 Shock-Expansion Theory. Web1 Introduction. Prandtl's theory of the lifting line gave the answer to most of the questions in the aerodynamic design of airplane wings. Thus the three-dimensional wing theory became a standard tool of airplane designers. One restriction involved in the conventional wing theory is the uniformity of the undisturbed flow in which the wing is ...
