GENERAL ELECTRIC AERIAL TRANSPORT SYSTEM, A BASELINE DEFINITION

THE GENERAL ELECTRIC AERIAL TRANSPORT SYSTEM (GEATS) UTILIZES A UNIQUE SUSPENSION CONCEPT IN WHICH VEHICLES ARE CONNECTED TO RUBBER-TIRED, ELECTRICALLY POWERED TRUCKS RUNNING WITHIN AN ENCLOSED BEAMWAY STRUCTURE. THE GEATS IS ESSENTIALLY A MODIFICATION OF THE SAFEGE SYSTEM IN FRANCE. THE REPORT DOCUMENTS EXTENSIVE TESTING OF THE SAFEGE CONCEPT WITH REFERENCE TO SAFETY, VEHICLE STABILITY, AND RIDE QUALITY. SEVERAL ADVANTAGES OF THE GEATS DESIGN ARE HIGHLIGHTED: (1) LIMITED LATERAL SWINGING MOVEMENT OF THE COACH BODY; (2) EASE IN NEGOTIATING CURVES; (3) SIGNIFICANTLY REDUCED NOISE LEVELS (DUE TO THE BEAMWAY DESIGN), AND (4) IMPROVED VEHICLE PERFORMANCE RELATIVE TO PASSENGER COMFORT, TRACK ADHESION, AND OVERALL MANEUVERING AFFORDED BY THE USE OF PNEUMATIC RUBBER TIRES. SYSTEM PERFORMANCE IS EVALUATED WITH REGARD TO STATION, GUIDEWAY STRUCTURES, VEHICLES, AND OVERALL SYSTEM CONTROL. PASSENGER COMFORT CRITERIA ARE DEVELOPED AND COMPARED WITH PERFORMANCE SPECIFICATIONS; EMERGENCY AND ENVIRONMENTAL CONSIDERATIONS ARE ALSO DISCUSSED. TECHNICAL ASPECTS OF THE SYSTEM ARE EXAMINED IN TERMS OF VEHICLE DYNAMICS, PROPULSION AND BRAKING, GUIDEWAY CONFIGURATION AND SUPPORT STRUCTURES, STATIONS AND FARE COLLECTION, AUTOMATIC TRAIN CONTROL, AND MAINTENANCE AND ADMINISTRATION. POTENTIAL ADAPTATIONS OF THE BASELINE SYSTEM FOR HIGH-SPEED AND SMALL-VEHICLE APPLICATIONS ARE EXAMINED. A GEATS POWERED BY LINEAR INDUCTION MOTORS TO ACHIEVE HIGHER SPEEDS IS SUGGESTED. THE GEATS WOULD BE PARTICULARLY EFFECTIVE WHEN ADAPTED TO MOVE SMALL-VEHICLES (LESS THAN 10,000 PASSENGERS/HOUR CAPACITY) OVER SHORT DISTANCES WITHIN A DENSE URBAN AREA. /UMTA/
