TRANSONIC HODOGRAPH DESIGN-PROBLEMS

The hodograph method is used to formulate several design problems in t ransonic flow using small-disturbance theory. Analytical and numerical methods give solutions to several optimum critical airfoil designs wi th different constraints on the tail angle. Special airfoil shapes fly ing at free-stream Mach number one are designed. The problem of constr ucting a shock-free body of revolution at subsonic speed but having a supersonic zone is formulated in the hodograph and solved numerically.
