| Abstract |
THE GENERAL CONCEPT OF THE DEMONSTRATOR IS TO SIMULATE A SINGLE STAGE OF GRAVITY VACUUM TRANSIT (GVT), WITHOUT INCURRING THE TIME AND EXPENSE TO BUILD A TUNNEL. THE DEMONSTRATOR WOULD CAUSE A TRAIN TO PASS FROM ONE STATION TO THE OTHER WITH INSTRUMENTS AND/OR A LIMITED NUMBER OF "PASSENGERS". THE TRACKS AND TUBE WOULD BE INSTALLED IN A REPRESENTATIVE MANNER, AND THERE WOULD BE REPRESENTATIVE VALVES AT BOTH ENDS. ONLY ONE OF THE TWO TUBES WOULD BE EQUIPPED TO CARRY A TRAIN; THE OTHER WOULD BE PRESENT TO ASSURE DYNAMIC SIMILARITY TO THE OPERATIONAL INSTALLATION. SIZE OF THE TUBES, TRAIN, AND VALVES FOR THIS PURPOSE WAS SELECTED TO BE A FULL-SCALE REPRESENTATION OF THE MARK 3B OPERATIONAL SYSTEM. THIS SAVES COST AS COMPARED TO THE MARK 4B SYSTEM, WHICH IS SIMILAR IN VIRTUALLY ALL RESPECTS BUT APPROXIMATELY 16% LARGER. SYRACUSE UNIVERSITY RESEARCH CORPORATION SELECTED A SITE IDENTIFIED AS "TULLY 1" FOR ITS TOPOGRAPHY, ITS ACCESSIBILITY, AND PROSPECTIVE AVAILABILITY OF ELECTRICAL POWER. ESTIMATED COST TO CONSTRUCT THE DEMONSTRATOR AND CONDUCT A TEST PROGRAM AT 170 MPH IS $26 MILLION. THIS ESTIMATE IS PREDICATED ON CONSTRUCTION IN THE TIME PERIOD 1971-72. IT INCLUDES A TEN PERCENT CONTINGENCY FACTOR TO ACCOUNT FOR CERTAIN TECHNICAL UNKNOWNS. THE TIMESCALE FOR THIS DEMONSTRATION IS ESTIMATED AT 25-27 MONTHS AFTER GO-AHEAD, ASSUMING THAT THE REFERENCE (3) PROGRAM IS LAUNCHED SOME EIGHT MONTHS EARLIER. UPGRADING THE FACILITY AND CONDUCTING ENGINEERING TESTS AT 250 MPH IS ESTIMATED TO REQUIRE AN ADDITIONAL $1.0 MILLION AND WILL TAKE FOUR MONTHS, IF NO SERIOUS PROBLEMS ARE ENCOUNTERED. /UMTA/ |
