ABSTRACT:
Two wing semi-spans of unitary construction are mounted on an aircraft fuage. Screwjacks mounted in the fuselage extend and retract each semi-span while maintaining the wing sweep angles constant. Pivoting struts and carriage blocks are employed to support the extensible semi-spans. Rollers connected to the carriage blocks are constrained to follow tracks mounted in the fuselage, providing support at the inboard end of each semi-span.
