Summary:

The evolution of light aircraft design has tended to emphasize payload/range capabilities. A less understood but extremely meaningful area of design, the integration of cruise speed and low-speed flight aerodynamic optimization, is discussed here.High-lift technology has found broad application in large transport aircraft, but virtually none of this technology has been integrated into general aviation aircraft for reasons of cost, complexity of design, lack of low-cost manufacturing adaptability, et cetera However, transport-category aerodynamic technology can be applied to general aviation and business aircraft.The application of extensive high-lift devices in conjunction with increased low-speed lift/drag ratio, and advanced airplane control systems to general aviation aircraft is reviewed.Parametric studies of pertinent wing aerodynamic variables were performed for a typical twin-engine propeller aircraft. Wing loading and aspect ratio are optimized for both slow-speed engine-out operation and cruise speed and payload/range.The results are encouraging, and point the way for serious consideration of the integration of advanced technology aerodynamics with propeller-driven twins. Such integration greatly increases these aircrafts' productivity, efficiency, speed, and safety
