ROMANIAN PRODUCTION
In 1983 there was established in Romania, the Aviation Engines and
Reducers Plant of I.Av.
Bacau. They produced the Yak-52 airplane. They also started producing
the M-14P and
M-14V26 engines, the reducers R-26 and VR-126 and the jet engine
RU-19A300. The company
I.Av. Bacau has since become S.C. AEROSTAR S.A. The former Aviation
Engines and Reducers
Plant is now a separate company having the name MOTORSTAR S.R.L.
Starting with the year 1999, MotorStar S.R.L. introduced some
improvements at the M-14P
engines. They developed an adapter drive for UMA tachometers and an
adapter for Skytronics
alternators. They also developed and installed an adapter drive for a
vacuum pump. The
engine look was improved by adding the Âdress kit consisting of
many chrome plated bits.
They developed a ÂWestern SAE#2 propeller shaft for the engine.
In 2000 they
developed
the Romanian 400 HP version. The gear train of the supercharger was
modified and the
maximum impeller speed reached 30000 RPM. The result is a higher
manifold pressure and
more power.
In 2001 MotorStar S.R.L. developed an electric start system for the
M-14P engine using the
electric starter, produced by B&C.
Also in 2001, MotorStar S.R.L. Designed and began manufacture of the
M-14D.
Based on the M-14V26 engine the M-14D is a direct drive engine with
the similar
performance as the Continental W-670 engine, but smaller diameter and
less weight.
MotorStar S.R.L. continues to produce the M-14P engine as well as
overhaul the M14P, the
M-14V26 and the AI-14R engines.
==============================================================
The engines cost about $30,000.
It is not clear to me how the ring gear is driven by the crank
shaft. In the rotary application the ring gear will be held stationary and
the sun gear will be driven. Fortunately the power will be out
of the planet carrier which is the same situation for the radial
as well as the rotary. This might be rather easy to do with only
a few new parts. My guess is the gear box will be about $5000.
P-port 3 rotor engines can be made with after market parts made in Oz or
New Zealand using stock 13b rotors, end housings and rotor housings.
This gear box would be a good match.

Here is some info on the gov.
Paul Lamar
In this dwg it looks like the gov is driven off the cam shaft.
In that case it will be necessary to drive the gov off a cog
belt on the nose of the e-shaft. That will requires a mounting
bracket with a ball bearing to take belt loads.
BTW It is now obvious how the ring gear is driven by the crank.

Paul,
Unfortunately the governer is run of the cam plate and uses engine speed
not propeller speed.
The engine turns at 2900 rpms redline. There will need to be some new
gearing to make the input shaft to the governor the same speed.
Pictures of the governor aren't going to help you need pictures of
the governor drive and the cam plate to figure out the ratio so we can
work out the new ratio for 7000 rpms
(engine rpms)
The camplate is sound but the crankshaft (which will be the shaft
that is attached to the fly wheel.

You don't have to use the Russian gov. A US gov may be a better
match for a US prop.
Paul Lamar
Paul ,
I see that now. Wow Where can I get a bracket like that?? That
simplifies the adaptation immensely.
Will
The company that made that went out of biz.
