<p>Airplanes which feature composite construction and have: a further aft than conventional center of gravity; a clean wing with a high aspect ratio; and all primary flight controls. These include trailing edge control segments (or members or elements) which extend the full span of the airplane wing. A central processor so schedules the upward and downward deployment of the control elements that: (1) downward and upward displacements of the control elements are respectively accompanied by pitch-up and pitch-down moments; (2) the inboard control elements are used primarily to change the coefficient of lift whereas roll control is effected principally by displacement of the outboard control elements; and (3) each of the control elements is individually displaced by a system which eliminates hydraulic systems a nd control cables. Hallmarks of these novel airplanes include simplicity, relatively low cost, lower weight, and safety.</p> |
