MODEL EXPERIMENTS ON THE AERODYNAMIC BRAKING OF SUCCESSIVELY RUNNING WAGONS IN TUBE TRANSPORT SYSTEM

To evaluate effects of aerodynamic braking of vehicles having large end plates in the tube-wagon transport concept, experiments on a 1/50th size scale model with 30-m tube have been carried out. Influence of the air compressibility was ignored because of the low Reynold's number of the set-up. It was demonstrated that the aerodynamic braking force increased with the blockage ratio of the end plates, approaching unity. The ratio decreased when the number of vehicles in the tube increased.
