| 摘要： | The current state of ejection seat/sled testing employs an Aydin/ Vector Co. pulse code modulation/telemetry instrumentation package. While this system meets all channel/data rate requirements and has proven itself in field testing, some major deficiencies exist. Data turnaround is one drawback; up to several weeks are normally required to process and print out the results from any sled shot. A second major deficiency is the amount of data dropout that can occur. In an ejection seat test, orientation of the skull antenna or misalignment of sending and receiving antennas can result in loss of data. Current technology in data storage media and high-speed controllers provides backup mode for data integrity and also permits faster data reduction. This paper summarizes an electrical/mechanical packaging design of a software controlled, nonvolatile data recording system which uses 8 megabits of bubble memory to provide 24 sec of data storage in parallel to the PCM/TM transmission. Preliminary laboratory bench testing of the Solid State Memory Instrumentation (SSMI) Recorder indicates that the bubble memory can withstand the high vibration g loads (20 Gs up to 2000 Hz) and environmental temperatures (85 C) encountered in ejection seat testing. Laboratory shock testing (ejection seat trainer) to 5 Gs has also been successful along with tower testing at the Naval Air Development Center to 25 Gs. Keywords: Nonvolatile magnetic bubble memory; Anthropomorphic dummies; Sled ejection seat testing. |
