MEMORANDUM FOR THE RECORD
SUBJECT: Trip Report, 22-24 July 1969
1. Locations and Puoses of Visits:
The undersigned visited the David Clark Company in
Worcester, Massachusetts, on 22 and 23 July 1969, and the
ARO Corporation in Buffalo, New York, on 24 July 1969.
The purpose of these visits was to identify the require-
ments and existing assets to rework or fabricate S 1010-
PPA's for the new pilots coming aboard in FY-70. In ad-
dition, it was necessary to review the delivery problems
of the ARO.Corporation, especially in view of the strike
at the parent facility in Bryan, Ohio.
2. Results of Visits:
(a) David Clark Company - A complete review was
held with the two factory technical representatives
of both customer S 1010-PPA requirements for the coining
year. Customer Two is increasing its total mission
pilot complement from 15 to 18 each of whom will event-
ually require two S 1010-PPA's. Technical status of
Engineering activities on the S 1010-PPA were dis-
cussed with special attention directed at helmet tie-
down straps and improved glove disconnects. A preliminary
USAF review(s)
completed. S E C R E T

cold-water immersion evaluation was conducted in the
water tank utilizing the new thermal protective layer
with the undersigned as the experimental test subject.
(See attachment # 1). Plans are being made at the
present time for final testing in early fall in a
climatic chamber.
(b) ARO Corporation - A review of all Task Orders
was accomplished with the
Company representatives, Mr. Roy Horton of the WRAMA,
the Contract Monitor, and the under-
signed 1 e dance. Estimated delivery dates for
items still outstanding will be forwarded by ARO to
this Headquarters by the end of July. Discussions were
held on the FY-70 contracts and the impact of the ARO
Corporation strike on our mission. The Buffalo facility
.is presently attempting to meet its obligations with a
physical move of much of the equipment from the parent
facility at Bryan, Ohio, to Buffalo.

Evaluation of Cold-Water Survival Protection
Provided by the 51010 Pilot's Protective Assembly
Utilizing a New Thermal Protective Layer
1. BACKGROUND - Testing of the S1010PPA in cold-water
immersion and subsequent life 'raft boarding is a matter
of record in a complete and comprehensive report by
formerly of this Headquarters.
is suggestion, -o owing the immersion studies, a
method of increasing insulation without sacrificing com-
fort to any degree was undertaken at the David Clark
Company Engineering Study GN-3-107 Design, fabricate and
evaluate a Thermal Protective Layer for installation in
the 51010-PPA.
2. METHOD - A prototype orally inflatable thermal
layer was fabricated and installed in the 51010 prototype
suit number 400. The oral inflator valve exits the right
arm and is of the typical lock-type valve presently in use
in all inflatable survival and protective equipment.
(LPU-2P underarm preserves, one-man rafts, etc.) For the
preliminary test the suit was donned and the subject
immersed in a water tank cooled to 38?F.
3. RESULTS - Upon initial immersion, the inflatable
layer failed due to a weak seam and the subject was immedi-
ately removed from the tank. Repair was. accomplished and
re-immersion carried out with the thermal layer inflated
prior to water entry. Subjective observations and comments
(see table 1) indicate that this thermal layer will greatly
improve insulation characteristics of the 51010-PPA. After
one-half hour in the water, there was no reduction in body
temperature measured with an oral thermometer. This compares
favorably with earlier studies indicating a trend to reduction

in body temperature with the S-1010-PPA alone. Additional
effort is being made to fabricate another garmet for
installation and final testing will be accomplished in
early fall.
4. DISCUSSION:- It would appear from comparing data
from the cited study above (table # 2)' with this pre-
liminary evaluation, that an inflatable protective layer
will greatly increase the survivable immersion time of
a downed crewmember. Admittedly, this study had artifacts,
namely, the pre-chilling of the subject when the first
exposure failed, the constant leak of the garmet itself
making it impossible to measure pressure that is necessary
for adequate protection and finally, the use of two oral
thermometers in as much as the first one was dropped.
Hopefully,without these problems, a reliable index for
cold-water immersion protection can be established with
the final testing. _
