ae Waycrs) Project 5,2 = In-Flight Participation of a B-52 - Ist Lt, F. L, Williams OBJECTIVE The objective of this test was to determine the delivery capability of the B-52 aircraft. INSTRUMENTATION Instrumentation of the B-52 for the Mohawk) shot consisted of 310 oscillograph channels which recorded measurements from strain-~gage bridges, accelerometers, roll and pitch gyros, radiometers, and control position transducers, In addition, 15 cameras recorded photo-recorder instruments (14 channels), wing deflection, cloud coverage, and fireball rise and growth, AIRCRAFT POSITION IN SPACE The following chart shows the airplane's position at time zero and time of shock arrival: Conditions at Altitude (abs, ft) Offset (ft) Heading YI (true-deg Time Zero 25000 0 136 Shock Arrival 25000 0 135 Conditions at \ o DELETED .
