초록

An aircraft having supersonic and subsonic flight capabilities which utilizes a variable dihedral angle tail unit to vary the aircraft geometry to improve aerodynamic efficiency, especially when changing from subsonic to supersonic speeds and vice versa, which saves propulsion energy and can be used to present minimal radar cross section from a given direction.

대표
청구항

In an aircraft capable of supersonic flight having a fuselage, and a pair of wings connected to said fuselage, each of said wings projecting substantially horizontally and outwardly from said fuselage, a variable dihedral angle tail unit comprising: two tail control surfaces extending outwardly from said fuselage pivotally mounted to the upper body of the aft end of said fuselage about respective axes substantially parallel to the longitudinal axis of said fuselage, said tail control surfaces adapted to selectively provide both longitudinal and direction...
