Abstract

786,778. Aircraft. DELANNE, M. H. March 9, 1956, No. 36929/54. Class 4. A supersonic aircraft comprises a fuselage and two wings spaced apart longitudinally and vertically, wherein the rear wing is disposed with its leading edge extending no further forward than the plane of the shock wave issuing from the zone of zero pressure on the front wing, and with its zone of zero pressure extending no further rearward than the plane of the shock wave issuing from the trailing edge of the front wing. In Fig. 1, the wings 1 and 2 may be of rectangular plan. The horizontal interval d between the quarter chord points and the vertical interval e are determined by wind tunnel tests for minimum drag at a predetermined speed. The front upper wing may be set at a positive angle of incidence, and the other wing at a negative angle. Each wing may be triangular in plan, the outer portions of the rear wings being hinged about a spanwise axis to act as elevons.
