A PRELIMINARY STUDY OF THE COANDA NOZZLE PRINCIPLE FOR PROPULSION OF TUBE VEHICLES

The report describes experimental studies to determine the feasibility of a new type of mass transportation, called the IITRI Passive-Vehicle Tube Transport System. This system (1) uses propulsive guideway concepts based on solely fluid dynamical propulsion principles (the Coanda effect). (2) has the utmost mechanical simplicity, with no moving parts other than vehicles. (3) uses small, inexpensive vehicles providing a personalized mode of mass transportation. (4) is suitable for transportation of goods and passengers. The qualitative and quantitative results of the study provide an insight into various problem areas. The following features were demonstrated: (1) High subsonic speed potential (in the experimental mode, speeds up to 320 fps were reached). (2) Capability of high vehicular frequency. (3) High load-to-power ratios at speeds above 120 mph and at high vehicular frequencies. (4) System efficiency increases with increasing tube diameter. (Author)
