ee CHAPTER 3 RESULTS, MIKE SHCT 3.1 GENERAL The experimental device for Mike Shot was housed in a structure located on Elugelab Island in the Eniwetok Atoll. It was detonated at 0800 on the morning of 1 November 1952. The hydrodynamic yield was reported as 10.4 MIT. This yield was considerably higher than the pre-~ dicted most probable yield used as the basis for adjusting instrument sensitivity, and as a consequence certain channels of information were unintelligible for a short period after shock arrival because of the wide fluctuations caused by the higher-than-anticipated in,uts. After burst time and before shock arrival, the B-36 aircraft was allowed to lose approximately 1500 ft of altitude in order to increase flying speed, The aircraft was leveled off at an altitude of approximately 38,500 ft prior to shock arrival. Position at shock arrival, except for the lower altitude, was approximately as planned. Acceptable blast response measurements were made; overpressure measurements did not evince a high degree of reliahility. No blast response instrumentation data were obtained from the B-47 aircraft because of its excessive range at shock arrival. 3.2 AIRCRAFT POSITICN,INPUTS, FLIGHT DATA Data relative to the conditions of exposure for each aircraft are given in the sub-paragraphs telow. ‘here several measurements were made, the best average value is reported. Meteorological data such as the magnitude and direction of the wind at the test altitude were not recorded. 3.2.1 B~36 Aircraft Data pertinent to the exposure of the B-36D aircraft in Mike Shot are summarized below: a. b, Altitude, MSL, 38,500 ft Horizontal range at shock arrival, 127,100 ft 53 Pt a
