Hi Didier,
I think simple economics-the price will go up;people in the west will
have the incentive to make the parts,and the engines will go on being
rebuilt,but at greater cost!!

Hi Richard,
So will they build new motors???
Or will the price of the motors get higher and higher because of th
demand?
kind regards
Didier

For those who are interested in these things, I have just returned
from Moscow, and met with Yakovlev.
The order (which was between the Russian Minister of Transport and
the Smolensk factory for sixty 18Ts was actually extended to a further
fifteen, which were old airframes and rebuilt.
These aircraft have been delivered, but there have been huge
problems trying to get sufficient engines, and although nominally new we
know that large amounts of the engines are actually overhauled
components!
The Ministry has asked for further planes, but it would seem that
there are insufficient engines for the order to be taken.

To Rick Volker - thanks for the extra figures - that makes a lot more
sense.
Certainly the figures from Kevin Kimball make a lot of sense, and are
broadly in line with my own experience.
I am however surprised that there should be less thrust from a
MTV-260-29 than from a 250. Certainly the tests that we have done
with MT showed that the 260 gives significantly more static thrust, but
loses out a bit in terms of top speed.
I was also interested that Rick says that the MTV-9 is slower than the
V-530, whereas Kimball says the reverse, and again that is my
experience.
The practicality is that the V-530 is fifty year old technology, and
obviously things have moved on.

I would like to offer some information on the Dynamic balancing of these
props. All of these props should be able to be dynamically balanced. Even
the 530 without a spinner. I have balanced many 530's without spinners with
no problem, even down to .01 - .03 ips. As long as the prop and engine
are functioning properly the can be balanced. If any of the props don't
seem to want to balance and you are for sure that the prop is in good
working order and set up properly, then the problem will most likely be
with the engine.
