Project 5.7 - Thermal Flux and Albeic Measurements from Alroreft Capt. R. L. Dresser
QTY.
The objective of Project 5.7 participation or thie det was to obtain
thermal flux ard albe‘o irformation of a nuclear detonation with airborne
calorimeters, reaficmeters, and sixteen nillimeter motion picture cameras.
Inetrumentatior within the purview of Projeet 5.7 whieh was inetalied
in the 8-17 included nineteen BRDL calorimeters and two NWROL redioneters
for measuring the ‘direct and surface reflected thermal radiation. Siz
calorineters were utilised to measure thermal] redietion whieh was baskecattere?d toward the ooerpit.
Seven OSAP BO ceperas were utilise! to
obtain photegraphic coverere of the fireball, the earth's surface, and of
clouwls beneath the airera’t, and aleo of any refleeting surface such as
a clout which could oortribute to the back-scattere? radiation.
Project 5.7 ‘netrumentation on the A-52 iraluied the twenty-one
basic instruments for thermal radiation measurements, but only en additional
two inatruments were utilise! for back-scatter measurements,
Kight GSAP
Gameres were installei fer photo-raphic coverage.
Project 5.7 instrumentation on the 5-57 consisted of the basic tventyone inatruments and six cameras,
Project 5.7 inatrumentation on the Be-lé consisted of the basic twenty-
one instruments ani twelve cameras,
Neither tactical boeber (Bf, 8-57) vas instrumented for measuring
back-eeattered thermal radiation.
