Project 5,7 ~ Thermal Flux and Albedo Measurements from Aircraft Capt R. L. Dresser
OBJECTIVE
The objective of this shot was to obtain thermal flux and albedo
information of a nuclear detonation with airborne calorimeters, radiometers, and sixteen mm motion picture cameras,
INSTRUMENTATION
Instrumentation within the purview of Project 5.7 which was installed in the B-47 included nineteen NRDL calorimeters and two NRDL
radiometers for measuring the direct and surface reflected thermal
radiation,
4
Six calorimeters were utilized to measure thermal radiation
which was back-scattered toward the cockpit.
Seven GSAP N-9 cameras
were utilized to obtain photographic coverage of the fireball, the earth's
surface, and of clouds beneath the aircraft, and also of any reflecting
surface such as a cloud which could contribute to the back-scattered
radiation,
Project 5.7 instrumentation on the B-52 included the basic 21 instru-
ments for thermal radiation measurements, but only an additional two
instruments were utilized for back-scatter measurements.
cameras
Eight GSAP
were installed for photographic coverage.
Project 5.7 instrumentation on the B-57 consisted of the basic
twenty one instruments and six cameras,
Project 5.7 instrumentation on the B-66 consisted of the basic
twenty one instruments and twelve cameras.
Neither tactical bomber (B-66, B-57) was instrumented for measuring
