A preliminary study was conducted toward the optimum design of a composite wing-box structure for a civil tilt-rotor transport aircraft. This effort has been focused on two tasks: to study the intricate dynamic and aeroelastic characteristics of the tilt-rotor configuration, and to identify the proper procedures to analyze these characteristics; and to develop the structural modeling and analysis techniques necessary in the tilt-rotor wing design optimization. Following the completion of this task, and proper formulation of aeroelastic and structural constraints, the design optimization will proceed to develop a minimum-weight, tailored, lowerdrag wing design. In the preliminary design of the wing-box structure, the design variables will include only structural parameters such as thickness and orientation angles of the upper and lower-skin plies, spar and rib cap areas and web thicknesses, and stringer areas. The wing-rotor-pylon aeroelastic and dynamic interactions will be limited in the preliminary wing design by holding the cruise speed, rotor-pylon system and wing geometric attributes fixed.
