wer DELETED Project 5.7 - Thermal Flux and Albedo Measurements from Aircraft Capt R. L. Dresser OBIEST The objective of Project 5.7 participation on this shot was to obtain thermal flux and albedo information of a nuclear detonation with airborne calorimeters, radiometers, and sixteen millimeter motion picture cameras. | INSTRIMTTATION Instrumentation within the purview of Preject 5.7 which wes installed in the B-47 included nineteen NRDI calorimeters and two NROL radiometers for measuring the dircet and surface reflected thermal radiation. Six Calorimeters were utilized to measure thermal radiation which was back Scattered toward the cockpit. Seven CSAP N-9 cameras were utilized to obtain photorcraphie coverage of the firchell, the earth's surface, ani cf elouds teneath the eireraft, and elso of any reflecting surface such as a cloui which could contribute to the beck-seattered radiation, Project 5.7 instrumentetion on the B-52 included the twenty one basic instruments for thermal rediation measurements, but only an additional two instruments were utilized for back-scatter measurements. Fight GSAP cam- eras were installed for phetographie coverage. Project 5.7 instrumentation on the R-57 consisted of the basic twenty one instruments ani six cameras. Project 5.7 instrumentation on the B-66 consisted of the basic twenty one instruments ani twelve cameras. Neither tactical bomber (B-66, B~57) was instrumented for measuring back-scattered thermal radiation. The twenty one basic thermal instruments possessed various fields of view and were suitably filtered to obtain popred DOE patie BC . - 33 - it
