A V/STOL concept has been developed through adherence to a design philosophy of making each decision from the viewpoint of what is best for the overall airplane rather than for one system, such as propulsion. The acronym, ADAM, standing for Air Deflection and Modulation, has been applied to this concept. A typical design for a subsonic recce/strike airplane is described in detail and wind tunnel results are discussed. Performance data are given insofar as security classification permits. The airplane is characterized by a high degree of maneuverability and versatility. Application of the ADAM concept to transport types is treated briefly.
