FALLING-SPHERE EXPERIMENT FOR UPPER-AIR-DENSITY: INSTRUMENTATION DEVELOPMENTS
Abstract
The continuing development of the instrumentation for the falling-sphere experi ent for upper-air density and temperature is described. A multiple-circuit cavity for the accelerometer, which permitted the elimination of the wire bobbin contact, was developed. A moving iron solenoid caging device resulted in a smaller accelerometer requiring less power than the previ us model. A new Attwood's machine permitting laboratory tests at 1/1 00 g was constructed. Electronic circuits were developed to replace the intervalometer motor. Circuits were also devised to permit long transit times and to provide discrimination between start and stop pulses. Four spheres and accelerometers for flight test were constructed. (Author)
