ENERGY CONSUMPTION OF PRT SYSTEMS--A PARAMETRIC ANALYSIS OF FACTORS AFFECTING ENERGY CONSUMPTION IN PERSONAL RAPID TRANSIT SYSTEMS

IN THIS STUDY OF THE INTERRELATIONSHIPS BETWEEN THE PARAMETERS THAT AFFECT THE USE OF ENERGY BY PERSONAL RAPID TRANSIT (PRT) SYSTEMS, FOUR TECHNOLOGICAL APPROACHES TO VEHICLE DESIGN WERE EXAMINED. THEY ARE: THE AIR CUSHION/LINEAR INDUCTION MOTOR APPROACH USED BY TRANSPORTATION TECHNOLOGY INC., THE RUBBER TIRE/ROTARY TRACTION MOTOR DESIGN USED BY BOEING FOR MORGANTOWN; THE MAGNETIC LEVITATION/LINEAR INDUCTION MOTOR CONCEPT PRESENTLY UNDER DEVELOPMENT; AND STEEL WHEELS WITH SOLID URETHANE TIRES ON STEEL RAILS (NOT ANALYZED). THE VEHICLE SELECTED FOR ANALYSIS COULD SEAT 10 PASSENGERS (NO STANDEES). IN THE ANALYSIS, VEHICLE WEIGHTS WERE VARIED RANGING FROM 6000 TO 10,000 POUNDS. A CONSTANT VALUE OF 1.5 KW/TON WAS USED FOR LEVITATION OF BOTH AIR CUSHION AND MAGNETIC LEVITATION VEHICLES. LINE SPEED, FRONTAL AREAS, AERODYNAMIC DRAG, PROPULSION POWER AND EFFICIENCY, AUXILLIARY POWER, ROLLING RESISTANCE AND LOAD FACTORS ARE THE OTHER FACTORS THAT WERE CONSIDERED. A LIMITED NUMBER OF PARAMETERS WERE CHOSEN AND ALLOWED TO VARY OVER A REASONABLE RANGE. THE RESULTS OF THE STUDY ARE GRAPHICALLY ILLUSTRATED. THE COMPUTER PROGRAM USED TO HANDLE ALL THE VARIABLES CHOSEN IS REPRESENTED IN A PRINTOUT. CONCLUSIONS MADE ON THE BASIS OF THIS STUDY ARE PRESENTED. THE ENERGY CONSUMPTION RATES THAT SHOULD BE USED FOR PLANNING PURPOSES ARE SET FORTH. THE CRITICAL UNCERTAINITY RELATING TO LOAD FACTORS, THE SENSITIVITY OF ENERGY CONSUMPTION TO VEHICLE SPEED, THE ENERGY PENALTY FOR FOAM FILLED RUBBER TIRE SYSTEMS AND THE RELATION OF VEHICAL WEIGHT TO ENERGY COMSUMPTION ARE REVIEWED.
