Abstract : A study was made to establish the feasibility of a flywheel accelerator for testing man-machine systems under conditions of space flight. This flywheel must be capable of accelerating a 232,500-lb test package to 300g in five seconds. The flywheel configuration which is recommended is 145 feet in diameter; has 22 linearly-tapered box spokes; and has a subdivided box rim, 12.58 square feet in cross section. This wheel weighs 5 x 10 to the 6th power lb and can be constructed from commercial steels (U. S. Steel, T-1 and HY-80). The static analysis of stresses and displacements of a flywheel have been solved and some of the problems connected with latching-on a capsule have been studied. Also, such areas as power requirements, bearings, and capsule support have been discussed. (Author)
