Hi Gildas,

Thanks. I don't doubt there is a replacement for the SR-71
possibly a Mach 5 or 6 vehicle of terrific 'dash' capability
most probably utilizing scram-jet [supersonic ram-jet]
technology at altitudes above 60,000 feet.

A French aerodynamicist first began working on ram-jet
technology back in the late 1930s so it's not new. This type of
aircraft is exotic in relation to it's speed and heat resistant
construction but none of it is new technology which is - in fact
- quite old. But there's apparently a need to have this aircraft
as a one off or two off production that will of course cost
hundreds of millions of dollars to research then produce.

Stan Friedman mentioned, in another post, the cost associated
problem with serial production of aircraft. It's time consumming
and expensive.

For example the new Boeing 787 design is an aircraft built from
scratch and this first aircraft will be sold once tested rather
than just being a prototype to help keep down cost.

The F-117As are all hand built and no two are identical. The B-
2s are handbuilt but are uniformly jigged up and cost nearly a
billion a copy.

This cost problem would have been the same for the Hortons that
some claim flew near Mt. Rainer not even a full two years after
the end of the war.

It's fiction anyway.

The Hortons were in preliminary stages, one was a one third
scale model which was to be tested and the full scale version
wasn't ever flown.

Take one look at the intakes on the Hortons and that pretty much
trashes any supersonic theories. The intakes stalled the airflow
at faster speeds stalling the compressors a probelm that went on
for years until AVRO solved it with variable geometry inlets on
the Arrow's intakes.


Best,

Don Ledger
