WIND-TUNNEL STUDY OF STREAMLINER PASSENGER TRAIN

In the subsonic wind tunnel of the University of Michigan, tests were made in which the six components of aerodynamic force acting on a 1/12 scale model of a car of Train X were measured. The purpose of the tests was to obtain data for calculation of the stability of the train in high winds. Tests were made on the car by itself and in the presence of other cars. Tests were made with and without rails, and with and without a raised roadbed. Parameters varied in the tests were: (a) angle of yaw of the train to the wind; (b) angle of lateral rail of the car to the horizontal; (c) height of car above ground; and (d) wind-tunnel speed. Tests were also made on a 1/12-scale model of a standard boxcar, to obtain a standard of comparison. The results of the tests are presented in tables and figures.
