An analysis was performed to investigate the longitudinal stability and control characteristics of an ejector wing configuration V/STOL in transition. A derivative approach was used to obtain dynamic responses about specified trim speeds, and analysis of these responses provided an insight into the significant characteristics that might affect the pilot's control over the aircraft. The thrust levels necessary to meet the control requirements specified in MIL-F-83300 for a Level 1 category vehicle were determined as well. A similar study was made for a stowable rotor configuration, and results for the stowable rotor V/STOL and the ejector wing configuration were compared. Finally, the downwash characteristics of the ejector wing configuration were evaluated in terms of their effect on ground equipment and personnel. Spray generation during hover over water is also discussed.
