[QUOTE="overscan (PaulMM), post: 108242, member: 1"] Wrongly spelled - it was LOBOY not "Lowboy" :) [quote][SIZE=13px]...LOBOY, so named by NASA to describe an aircraft designed to fly continuously in ground effect over water. Flying in close proximity to the surface suppresses induced drag and results in maximum lift-to-drag ratios as high as 35 for the configurations studied... The LOBOY is powered by high-bypass ratio turbofans and requires thrust augmentation in the form of additional turbofan engines for takeoff, dash, and flight out of ground effect. The thrust augmentation engines can be Buried in the wing aft of the rear spar, with inlet: air provided by individual scoops hinged from the front spar. When these engines are shut down, inlets and exhaust ports are closed into smooth contours. An automatic flight control system is required for LOBOY flight to keep the aircraft at the proper proximity to the surface in a safe manner while sensing larger, oncoming waves over which the LOBOY must rise. Such a system is considered feasible.
