as “ =A) EEoun Project 5.) - In-Plight Participation of e B47 Aircraft - Lt, §. C. Leumans QBIRCTIVE The objective of this project is to measure the blast, gust and theres] effects of a nuclear Jetopation on an in-flight B-<7 aircraft, With the recorded data, the criteria and metho! use? in the B-i7 Weapon Delivery Wandbook may be verified or corrected. In addition, the project will pro- wide tasio research data for the design criteria of future 08a" afrecraft. TESTRIREPIATION Two bundred an’ seventy-three date channels vere available on this shot including seventeen nev channels at station 1044.0 of the fuselage te measure bending, shear and torsion from side loads, The remaining chan- pele recoried bending, shear and torsion in the ving and horisontal stab- 4liser, thermal inputs to the aircraft, thermally inivesd strain, tempereture measurements and overpressare. Pricr to shot participation 97% of theee channele vere operating satisfactorily. POSITION The B-47 aircraft was positioned for side-loade effects in this event. The aireraft wes flying et an ebdsolute altitude of 7,000 feet, an affect of 40,000 feet, s speed of Mach 0.75 and on « heading of 021° at both T, and ebook er-ival. at 7, the shot was ahead and to the left of the aircraft euch that the horiscntal range was 12,000 feet short of a point directly abeenm of ground sero, At shock arrival the aircra’t vas directly eabeaz of ground sero and exactly tangential to the impinging shook wave, BEST AVAILASHE © ° : te. ah oe aoe ry ead a -%2- nn cc pED'DOE gern fh RG ~ “Se
