THE TERRAFOIL: A NEW CONCEPT IN HIGH SPEED GROUND TRANSPORTATION

A NEW CONCEPT IN HSGT CALLED THE TERRAFOIL IS PRESENTED AND DISCUSSED. TERRAFOIL IS USED TO DESCRIBE ANY SURFACE- GUIDED LIFTING ELEMENT WHICH GENERATES A SUSTAINING FORCE BY VIRTUE OF ITS FORWARD MOTION AND INTERACTION WITH ITS GUIDEWAY. A TERRAFOIL VEHICLE (TV) IS A VEHICLE SUSTAINED, GUIDED AND CONTROLLED EXCLUSIVELY THROUGH THE AERODYNAMIC INTERACTION OF ITS TERRAFOILS WITH THE GUIDEWAY. THE POTENTIAL PERFORMANCE OF THIS VEHICLE CONCEPT IS DISCUSSED ONLY FROM A SEMI-QUANTITATIVE POINT OF VIEW AND CONCLUSIONS ARE DRAWN ON THE BASIS OF PRELIMINARY EXPERIMENTS AND ELEMENTARY ANALYSIS. THE PAPER IS INTENDED ONLY AS A CONCEPT EXPOSITION AND NO CLAIM TO RIGOR IN THE DISCUSSIONS IS MADE. INDEED, BECAUSE OF THE EXCEEDINGLY LIMITED INFORMATION CURRENTLY AVAILABLE REGARDING THE CHARACTERISTICS OF TERRAFOIL VEHICLES AND THEIR COMPONENTS A RATIONAL QUANTITATIVE ANALYSIS WOULD BE DIFFICULT IF NOT IMPOSSIBLE TO PERFORM AT THE PRESENT TIME. VARIOUS TYPES OF PROPULSION SYSTEMS FOR HSGT SYSTEMS IN GENERAL AND TERRAFOIL VEHICLES IN PARTICULAR ARE ALSO DISCUSSED BRIEFLY. /AUTHOR/
