The work presented in this paper is an experimental and analytical investigation of the performance of pneumatic tube vehicle systems. The experimental facility that was built is described. The effect of vehicle density, length, frontal shape, surface preparation, blockage ratio, and tube initial pressure on vehicle performance and tube pressure history was investigated, using data from the experimental facility. An analytical model, which assumed instantaneous polytropic expansion behind and compression in front of a vehicle as it travels down the tube, was developed. Reasonable agreement was found between the predictions of the analytical model and data generated by the experimental facility. Several conclusions based on the initial experimental data are made and the results were used to develop an analytical model for simulation of the full scale systems.
