Abstract:

This research program involved the design, development, fabrication, and testing of a bomb instrumentation system to measure the deceleration environment experienced by a bomb tail fuze well during impacts into reinforced concrete target. The test vehicle used was a 500-pound blunt nose projectile having a diameter of 9 inches. The tail fuze well was instrumented with a triaxial accelerometer system along with the necessary power supplies and matching electronics. Also mounted in the aft section of the projectile were three high-g FM telemetry transmitters. The output signals from the accelerometer package were used to modulate the transmitter signals, and this data was received in the reception station and stored on magnetic tape. To qualify the instrumentation system for the Eglin AFB sled tests, a ballistic qualification test was conducted in which the instrumentation system was mounted in a 4-inch conical nose projectile and impacted into a concrete target. The instrumentation system functioned properly during the test and was, therefore, accepted for use in the sled test program. Two sled-launched concrete impact tests were conducted at Eglin AFB using the blunt nose instrumented test projectile. Telemetry deceleration data was obtained from both tests and reduced and analyzed in conjunction with high-speed photographic test data and analytical simulation techniques. Author
