Abstract

A specialized computer progran was developed for the calculation of sailplane performance in wings-level and turning flight. The basis of the program was an existing nonlinear lifting-line technique which permitted calculation of wing characteristics throughout the entire useful range of angles of attack using tabular airfoil section data which included Reynolds nunber effects. This wing analysis was coupled with appropriate fuselage and enpennage models in an iterative solution which calculated performace in a trimrned condition by adjusting aircraft attitude and tail lift uitil the equations of vertical force and pitching moment equilibriun were satisfied. The program was checked against published flight test data with very satisfactory results.
