TRACKED AIR-CUSHION RESEARCH VEHICLE

THE TRACKED AIR-CUSHION VEHICLE (TACV) IS A PROMINENT CONTENDER FOR HIGH-SPEED GROUND TRANSPORTATION SYSTEMS OF THE FUTURE. IT WILL OPERATE ON A GUIDEWAY PROVIDING REACTION SURFACES FOR AIR CUSHIONS TO SUPPORT AND LATERALLY GUIDE THE VEHICLE. TWO GENERAL TYPES OF AIR CUSHIONS (PLENUM AND PERIPHERAL JET) ARE SHOWN. IMPROVED RIDE QUALITY CAN BE OBTAINED BY A SECONDARY SUSPENSION SYSTEM BETWEEN THE CUSHIONS AND THE VEHICLE STRUCTURE. ELECTRICAL POWER FOR THE VEHICLE IS PREFERRED, IF NOT MANDATORY, FROM THE STANDPOINT OF INSITU ENVIRONMENTAL POLLUTION. SOME OF THE MAJOR DESIGN REQUIREMENTS AND GOALS FOR THE RESEARCH VEHICLE INCLUDE A FORWARD SPEED OF FROM ZERO TO 300 MPH IN 60 MPH CROSSWINDS, WITH 300 MPH ATTAINED WITHIN 3 MILES, PRIMARY PROPULSION FROM A WAYSIDE-POWERED LIM (LINEAR INDUCTION MOTOR) SYSTEM WITH 10,000 LB MAXIMUM CONTINUOUS THRUST; 15,000 LB OVERLOAD FOR 1 1/2 MIN. THE GUIDEWAY DESIGN REQUIRES LEVITATION AND GUIDANCE SURFACES TO BE PLANAR AND MUTUALLY ORTHOGONAL AND THE LEVITATION SURFACE TO BE HORIZONTAL. AN 18-MONTH TEST PROGRAM IS PLANNED, USING THE INITIAL 6.2 MILES OF THE 5- X 8-MILE OVAL GUIDEWAY TO BE CONSTRUCTED AT THE DOT HIGH SPEED GROUND TEST CENTER IN PUEBLO, COLO. /AUTHOR/
