A Multivariable Design Case Study

Abstract

Undoubtedly the best known fixed wing Vertical and/or Short Take-Off and Landing (VSTOL) aircraft is the Harrier jumpjet. Work on this type of air-craft began in the fifties at Bedford with the “flying bedstead” experiments. The present-day GR7, FRS.2 and AV-8B Harrier are essentially upgraded versions of the original P1127 Harrier which first flew in 1960, the main differences being increased operating range, much advanced avionics and improved handling qualities. The vectored thrust capability has proved itself to have unique strategic advantages not only through short take-off and landing capability, but also for high manoeuvrability in the air. In addition to the obvious advantages of VSTOL operations from small destroyers at sea [27], they have also been used to great effect by the U.S. Marine Corps for their ability to support and supply the up-front ground troops [28].
