Work is described which was undertaken to develop and improve techniques for measuring forces acting on rocket sleds. The Chaparral sled was instrumented and appropriate calibration made for measurement of vertical forces acting on the sled by the slipper. Resistance thermometers were also applied for measurement of temperature in the vicinity of the gage. A study of the accuracy of the Tech-2 sled transducer was made, and revised instrumentation applied in order to improve the accuracy. A force measuring system utilizing strain gages was developed for the modular monorail force transducer. Analytical studies of the response of a simple strain-gaged force link were made in order to better understand the behavior of the sled transducers under dynamic loading. The last area of work described is that of a highly accurate technique of differentiating analog data.
