CHAPTER 2 PROCEDURE 2.1 GENERAL This chapter is divided into three main sections presented in approximate chronological order covering the following subjects: selection of aircraft ard criteria for exposure, instrumentation and cali- bration of aircraft, and field testing procedure. the operation is given below. A brief history of , . Both the B-26D aircraft and the Be47B aircraft were SAC (Strategic air Command) aircraft assigned to maDC (Wright Air Development Center). The 5-360 aircraft was manned by a crew from SaC; the B-47B aircraft by a waDc crew. The 5-36D aircraft was instrumerted by personnel from WADC Calioration of the aircraft oy the Structures Test facility of aircraft Laboratory was completed Following maintenance work performed at Carswell AFB, in the Mike (1 Noverser 1952) and King (16 November 1952) shots of IVY. The c-350 and B+L75 aircraft returned to the USA on Zl ‘November 1952 and 23 Novernber 1952, respectively. Following the retum, Structures Test facility performed a check calioration on the 3-36D aircraft and a com plete calioration on the 5-476 aircraft. Prior to participation in Shot 9 of UPSHOT-K.\CTHCLE, the empennage of the &36D aircraft was more comzletely instrumented. Insufficient time was available for calioration prior to the test; however, an instru- mentation sensitivity check was performed at CVaC (Consolidited Vultee Airer.ft VJorporation) to determine attenuation settings. For participation in the shot the aircraft was vased at Birtland arp in Albuquerque, arrivine tnere aprroximately 2 weexs cefore Shot 9, nfter the test the aircratt was flown to Fort «orth, Texas, where Convair calicrate! the emrenna.: instrumentation by tne point-load system, as well as by the wry ere Ne seg oe ate a 15 August 1952, the 5-360 aircraft was flown to tne forward area arriving at Kwajalein on 21 Sertember 1952. The b<1,7B aircraft was instrumented by AIPL (Aeronautical Ice esearch Laboratory) and readied for overseas flight at srisht-Patterson aFE. Insufficier.t time was available for calibration prior to overseas movement primarily because of maintenance difficulties, It arrived at Kwajalein on 2 October 1952, Both Aircraft participated am a am aircraft Latoratory during the ceriod 9 May 1952 to 15 June 1952, while the aircraft was Located at aright Field.
