Abstract
The Gulfstream II business jet is a low wing aircraft of moderate sweep featuring a T-tail arrangement and two aft-mounted turbofan engines. The paper outlines aerodynamic development of the configuration and control system, highlighting significant design decisions and aerodynamic characteristics with appropriate experimental data including force, pressure, and flow visualization results. Aerodynamic design considerations included: wing optimization to meet the requirements of high and low speed performance and a pitch-down stall break at all flight conditions while providing adequate fuel volume; nacelle-pylon-wing relationship for optimum drag, engine characteristics, and airplane balance; and an empennage arrangement providing satisfactory stability and control at all conceivable flight conditions. The Gulfstream II configuration provides strong aerodynamic resistance to inadvertent secondary stall entry and more than adequate recovery capability.
