MEMORANDUM FOR: General Carter 31
I ran across Mr. Jack Horner, Chairman of the Board of
United Aircraft (Pratt-Whitney) last week and we had a brief discussion
of the J-58 engine for the A-12 aircraft.
Horner stated that it was his opinion the J-58 engine is one of
the outstanding developments in jet engine manufacture so far attained
and actually has exceeded expectations. Horner stated deliveries
remain on schedule and that many production problems which had
affected earlier deliveries had been disposed of.
However, Mr. Horner made the point that the engine can not
be considered as a dependable aircraft engine until the very considerable
amount of research and development has been undertaken. This work
was continuing at their West Palm Beach developmental plant. This
comment was made when I inquired from Mr. Horner as to whether the
J-58 engine would be a suitable engine for a supersonic transport plane.
Horner stated that the cost to date of the development of the
engine was considerably less (approximately only 60%) of the General
Electric costs for development of the engine for the B-70. This, he
felt, was remarkable in view of the fact that the B-70 engine, the
sensitive parts of which are encased in an environment in which
normal temperatures are maintained, is a simpler development than
the J-58.
I would like to discuss the research program planned for
1963 and the prospect for ultimately developing a truly dependable
engine in other types of aircraft. 25X1A
