SUPPLEMENT TO SURVEY OF TECHNOLOGY IN FLUID SUSPENSIONS: PATENT SEARCH AND EFFECTS OF FORWARD SPEED

Supplementary information to that given in Part I, Survey of Technology for High Speed Ground Transport, Ref. 1, is presented for fluid suspensions and fluid-supported vehicle systems. Representative patent literature is described which shows that the existing basic concepts and configurations for fluid suspensions and associated vehicles are very old; however, many recent patents have been issued covering variations, improvements and applications to transport vehicles. Published information and experimental facilities and techniques relative to the influence of forward speeds on fluid suspension data are reviewed. Available data are limited to forward speeds less than 150 mph, to ambient pressures of one atmosphere and to low cushion-pressure levels. An adequate theoretical approach to forward speed effects is lacking. No experimental facilities entirely satisfactory for the investigation of the behavior of dynamically similar scale models of HSGT vehicles and guideways were found to exist in the world. (Author)
