A study of a VTOL thrusting ejector in low speed flight, volume 1

Low speed aerodynamic characteristics of a thrust augmenter wing suitable for vertical operation were investigated. Wind tunnel test results on the ejector and a similar configuration with a blown flap are analyzed. The configurations represented a VTOL concept at conditions of thrust deflections required for low forward speed flight. The model tested had an unswept untapered wing. Specific data included normal longitudinal forces and monents, surface pressures, ejector exit surveys, and flow field surveys behind the wing.
