APPLICATION OF SCALING DATA TO MODEL TESTS TO OBTAIN FULL- SCALE RESULTS-INTERIM REPORT

A PROCEDURE FOR APPLYING SIMULATED EXPERIMENTAL DATA TO DETERMINE AERODYNAMIC AND HEAT TRANSFER CHARACTERISTICS OF FULL-SCALE SUBWAY VEHICLE SYSTEMS IS OUTLINED. PARAMETERS FOR THE STUDIES INCLUDE: (1) STEADY-STATE AERODYNAMIC EFFECTS; (2) UNSTEADY AERODYNAMIC EFFECTS; AND (3) HEAT TRANSFER CHARACTERISTICS (SIMILITUDE OF BRAKING HEAT). SOME OF THE TESTS WILL EMPLOY ORDINARY CYLINDRICAL MODELS BUT WITHOUT CONSIDERATION AS TO THE SCALING OF SPECIFIC VEHICLE GEOMETRY, WHILE THE OTHER TESTS WILL UTILIZE GEOMETRICALLY SIMILAR MODELS WITH DIFFERENT PHYSICAL PARAMETERS. SPECIFIC PARAMETERS FOR EACH PROPOSED EXPERIMENT ARE EXAMINED. THE SIMILITUDE LAWS WHICH WILL PERMIT APPLICATION OF DATA OBTAINED FROM MODEL TESTING TO FULL-SCALE VEHICLE SYSTEMS ARE EXAMINED. /UMTA/
