Project 5.7 — Therma] Flux and Albedo Measurements from Aircraft Capt. R, L, Dresser
OBJECTIVE
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,
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,
Six.
ealorimeters were utilized to measure thermal radiation which was backscattered 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 B52 included the twenty-one basic
instruments for thermal radiation measurements, but only an additional
two instruments were utilized for back-scatter measurements,
.
Eight GSAP
cameras were installed for photographic coverage,
The B-57 had no planned participation in this event,
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
back-scattered thermal radiation,
The twenty-one basic thermal instruments
\
possessed various fields of view and were suitably filtered to obtain
