LOW-ALTITUDE-FLIGHT MEASUREMENT POD (SANDUSTER). POD MEASURES AND RECORDS CHANGES IN AIRCRAFT ALTITUDE, ATTITUDE, AIRSPEED, AND VERTICAL ACCELERATION.

Abstract

The SANDUSTER program required a pod instrumented to measure changes in aircraft altitude, attitude, airspeed, and vertical acceleration with respect to time during low-altitude flight. The report describes the pod and its operation. Accuracies of the measurements are as follows: Altitude: Radar altimeter, Differential pressure transducer, =5 per cent of servo setting, and =100 feet at flight altitudes below 2,000 feet; Airspeed, =20 knots; Yaw, pitch, and roll rate, =1 degree per second; and Vertical acceleration, =5 per cent. Measurement accuracy and reliability could be improved by (1) replacing the existing radar altimeter with a more modern version, and (2) replacing the airspeed and altitude measurement transducers with more modern versions. The use of batteries would make the power system independent of the aircraft carrying the pod. (Author)
