dynamic responses will be considerably improved as a result of data obtained.
A test of an Air Force B-66 proved the delivery capability of this aircraft. Sufficient data were obtained to define safe-delivery envelopes and
to improve the ability of the aircraft industry to predict structural dynamic
responses.
Testing of an /ir Force B-57 proved the capability of this aircraft to
deliver nuclear weapons, Gust loads of 20 to 65 per cent of design limit
for shear on the wing were measured. Temperatures up to 580°F were
obtained on the black, thin-skinned, control-surface tabs. Suiticient data were
obtained to define safe-delivery envelopes of the black-painted B-57.
A test of two Air Force F-S4F aircraft was successful in the completion
of its two-fold objective to (1) determine its capability to deliver nuclear
weapons, and (2) provide side-load data for aircraft structure research.
Both aircraft measured hich inputs, with resultant high aircraft structural
responses to assist in defining the safe-delivery envelopes.
In addition, the
side-load aircraft provided data that were not previously available to the
aireraft industry.

A test of an Air Force F-101A was successful in the determination of
the capability of the F-101A to deliver nuclear weapons. Measured data
included temperature vises up to approximately 500°F and gust responses of
300 per cent of design Himit on the wing. The safe-delivery envelopes may
be clearly defincd from the data chtained in the test series. A supersonic
run was made on one event, with the expected thermal inputs and with no
overpressure or gust inputs.
Program 5 successfully measured ‘thermal inputs and obtained useful *
fireball~spectral-distribution information from sinstrumentation mounted on
thes B-47, B-52, B-66, and B-57.
<A test of a Navy A3D-1 proved the capability of the A3D-1 to deliver nuelear weapons. Data obtained during the test indicate a better capability than
‘had been predicted by theoretical analysis, The A3D-1 was the first Navy aircraft with a high-yield weapon capability to be proven in an actual! test series.
Over 100 specimens were mounted on towers and cxposed to a fireball
environment to determine the thermal Icthality of a nuclear detonation to
certain basic missile structures and materials. To date, only a few specimens have been recovered. Results of this project must be held in abeyance
until the nuclear~radialion ficlds are low enough to permit recovery.

Program 6, Service Equipment and Techniques
This program, consisting of five projects, had a great amount of
activity outside the PPG with stations extending from the Eastern United
States to Hawaii and the Western Pacific.
