LACRCSSE Project 5.7 - Thermal Flux end Albedo Measurements from Aircraft Capt, R. L. Dresser The objective of this shot was to obtain thermal flux and albedo inforzation of a nuclear detonation with airborne calorimeter, radiobars, and sixteen mn, motion picture cameras, Instruxentation within the purview of Project 5.7 which was installed in the B-57 included nineteen (19) NRDL calorimeters and two (2) NRDL vaiioneters for measuring the direct and surface reflected therval radietion, These instrucents possessed various flelds of aw fl rnd were suitably filtered to obtain qualitative spectral distribution crvation. . Six (6) GSAP N.-9 cameras vere ulilized to obtain olograplie osvo.sge of the firckall, the © .th's suvtece, end of ssnezth the aircraft. Two (2) of the cameras oriented towards .cumd were were equipped with spectroscopic attachments to obtain 2 atinucugs spectra in the visible region, Of the other two (2) tail position cameras, one camera had a blue filter and the other had a red vilter for the purpose of obtaining pictures at both extrexes of the fon of the spectrum, The revaining two (2) cem2ras were ovfented vertically for the purpose of obtaining photegraphie coverage of the carth's gurface and of eleouds bernesth the aircraft, Instruzentation installed in the B-66 ecnsisted of the basic make twenty-one (21) thermal instruments, and twelve (12) cameras. - 53-
