Optimum Tail Fairings for Bodies of Revolution.
Abstract
This report describes a computerized method that will design tails for bodies of revolution that satisfy the Stratford criterion for zero wall shear. Stratford's original two-dimensional solution is extended to axisymmetric flow in order to implement the procedure. The method involves simultaneous solution of the extended Stratford equation and the necessary boundary conditions through the use of an inverse potential flow program. Tails designed with this procedure can be categorized as follows: (1) The entire tail is at incipient separation (no skin friction); (2) The pressure recovery is the most rapid possible; (3) The resultant tail is the shortest possible. The final result is a unique geometry for given freestream conditions and boundary layer transition point. By unique, it is meant that any deviation from the 'ideal' geometry will either cause extensive separation or the tail must become longer and, hence, contribute to skin friction and reduced volumetric efficiency.
