Project 5.7 - Thermal Flux and Albedo Measurements from Aircraft Capt. R. L. Dresser
OBJECTIVE
The obsective of Project 5.7 participation on this shot was to
obtain thermal flux and albedo infcrmation of a nuclear detonation
with airborne calerimeters, radicmeters, and sixteen millimeter
motion picture cameras.
INSTRIM™TATION
Instrumentation within the purview of Project 5.7 which was
installed in the B-47 included nineteen NRDOL calorimeters and two
NROL ratiometers for measuring the direct and surface reflected
thermal radiation.
Six calorimeters were utilized to measure thermal
4
étiation which was back-scattered toward the cockpit.
Seven GSAP
“-9 camcras were utilized to cbhtain photograchie coverage of the
Fireball, the earthts surface, and of clouds benezth the aircraft,
and also cf any reflecting surface such as a ecleud which could contribute to the back-scattered radiation,

Project 5.7 instrumentation on the 252 included the twenty one
ruments for thermal radiation measurements, but only an
ch
aidi icnal two instruments were utilized for back-scatter measure=
ments,
Eicht GSAP cameras were installed for photegraphic 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, 3-57) was instrumented for messur-~
ing back-scattered thermal radiation.
