INSTRUMENTATION FOR AIR DENSITY MEASUREMENTS.

Abstract

This report details an operational system for measuring air density at altitudes above those investigated by instrumented balloons and below those investigated by orbiting satellites. The system described is a 7-inch, rigid, falling sphere which is ejected from a rocket and falls through the atmosphere. Measurements directly related to air density are obtained by using a transit time accelerometer and related electronics incorporated within the sphere. The system has been used for a total of twenty-eight flights during this reporting period and has provided air density measurements between 20 and 120 km. (Author)
