Methods were developed for measurement of specific components of forces acting on rocket sleds during runs. The forces acting on the sleds for which the instrumentation was developed to measure were the thrust forces from the pusher, the braking forces, and forces acting on the slipper by the track. The methods of measuring the forces included instrumentation of the existing sled structures with strain gages and use of specially developed force transducers which were mounted on the slippers. For both force measurement methods, static calibration procedures were used. The transducer developed was a three component force transducer, measuring two orthogonal components of force and one moment component. Two of these transducers were manufactured and sent to Holloman Air Force Base for use. In addition to the development of methods of measuring forces, the contractor consulted with the Track Test Directorate on problems related to force systems acting on sleds and behavior of the sled due to the force systems. Descriptions of this work are included. Author
