Mappscs210) Project 5.2 ~ In-flight Participation of a B-52 + Istlt. F. Ll, Williams Ob jective The objective of this test was to determine the delivery capability of the B-52 aircraft. Instrumentation Instrumentation of the B=52 for th _ (FLATHEAD) consisted of approximately 320 oscillograph channels which recorded measurements from strain-gage bridges, accelerometers, thermocouples, pressure transducers, calorimeters, roll and pitch gyros, radiometers, and control position transducers. In addition, 13 cameras recorded instruments, wing deflet- tion, cloud coverage, and fireball rise and growth, Results ms The Be52's participation in tne agg Lacan) shot was unsuccessful, Takeoff was not accomplished until 0510, one hour and 14 minutes later than scheduled, The radar stabilization unit did not have sufficient time to cycle on the ground, and though attempts were made to stabilize it after takeoff, proper operation was not achieved, In view of the necessity of obtaining an exact position in space and the possible error in the BNS due to the non-stabilized condition, it was decided to abort at the latest possible time. Technical considerations preclude the use of manual positioning. At time zero the aircraft position was approximately 60,000 feet from ground zero on an outbound heading of 135°T, The instrumentation was "ON" during the test. There were no measur- able inputs or responses, COPIED/DGE LANL RO uni Li
