    Abstract

    The optimum aircraft wing configuration for a low-level ground attack mission is investigated. Wing planform variables, wing thickness ratio and wing loading were optimized to achieve the maximum radius of action for a given amount of fuel and armament, assuming fuselage and empennage geometry and engine to be frozen, using a modular interactive computer program. The iterative program is designed to estimate wing geometrical quantities from configuration variables, evaluate wing aerodynamic characteristics, estimate structural weight, compute point performance parameters and adjust design parameters until an optimum is reached. For a given starting configuration, the program is found to provide an optimal configuration which increases the radius of action by 5 nautical miles without violating preset constraints on design variables, take-off distance or all-up weight. The inclusion of design variables characterizing the fuselage and empennage and further constraints into the procedure are under investigation
