DRAG ON VEHICLES IN TUNNELS

Conditions simulating a high speed ground transportation vehicle traveling in a long tunnel have been experimentally and analytically investigated to determine the effects of certain factors on the aerodynamic drag of the vehicle. The same vehicles and tube were used in two types of tests. In one, the vehicle was in a flowing air stream but remained stationary with respect to the tube, simulating wind tunnel testing. In the other, the vehicle was propelled along the tube under air flow conditions simulating an infinitely long tube.
