SUBJECT: Non-Metallic Construction for LH2 Tankage
25X1A9a
During recent visit to our facility, discussions were
held on unknown factors which needed to be investigated before an
authoritative decision could be made on the feasibility of the Blivot
concept. One of these involved the properties of non-metallic sand-
wich construction for containment of the liquid hydrogen fuel for
this application.
At this point, this type of construction provides inherent advan-
tages of light weight,.producibility, and aerodynamic smoothness.
In addition, theoretical studies by our engineers showed that non-
metallics should prove superior to conventional structures for LH2
tankage applications. To ex erimentally determine the accuracy of
this latter premise, requested that we formulate a
suitable test program to be submitted for your funding consideration.
In compliance with his request, two copies of our Pro osal No. 100-2989
accompany this memorandum, along with one copy of initial 25X1A5a2
Engineering Report No. 66-E5 on Thermostructural Design Concepts for
LH2-fueled Hypersonic Vehicles (it should be noted that the latter
was an independent work having no relationship to the Blivot concept)..
As indicated in the accompanying proposal, we feel-that a relatively
short 14 week program should not only prove the. feasibility of non-
metallic construction for the Blivot, but also permit the selection
of the optimum wall configuration for any desired future weight and
structural design studies.
Your consideration of this proposal, or any modification thereof, is25XlA5a2
solicited. Incidentally, recently spent a day consulting
at the Area under tail-end CS-200 funding; reports have indicated
that this visit proved of aid to your personnel at that facility.
It is hoped that this consulting relationship can be maintained via
a contractual arrangement similar to that outlined by 25X1A5a2
in our memorandum DTEM 1664 of 17 February 1967. Your consideration
of the latter proposal would alsi~"1 ciated.
