British Patent Abridgments

Abstract

An aeroplane comprises a body of delta planform, two wings extending from the ends of the base of the body and pivotally connected thereto for adjustment in sweep during flight, and means for rotating the wings during flight in relation to the body about an axis parallel to the OY axis of the aircraft irrespective of their position in sweep. In the illustration the body A comprises a central structure B, and two conical frame members CA, CB, are mounted in structure B by flanges D co‐operating with a fixed bearer (not shown), so that they can be rotated about axes parallel to the aircraft OY axis by independent fluid pressure jacks JA, JB. Each member CA, CB, has a pivot G on which a wing HA, HB is mounted so as to be variable in sweep. The wings HA, HB can thus be varied in incidence to suit the air speed and can be adjusted in incidence together for control, or differentially for roll control. A vertical stack of jet propulsion engines is located in a fin BA, with an air inlet L.
