The other day I had a chat with a friend who
owns a M14P powered homebuilt.
He told me he doesn't have much luck with
with the original engine driven compressor
and is now thinking about removing and replacing
it with a Series 32 Cornelius 3-stage 1500psi
27VDC compressor (installed in the rear part of
the fuselage).
He has no retractable undercarriage and no
pneumatically operated flaps and brakes,
his air system is only used to fire up the engine.
I suggested to convert to an approved electric start
system but since he has already that surplus compressor
(and a skinny wallet), he would like to give it a try.
I am always very skeptic if someone deviates
from the designer's path, but since this is a
homebuilt - different rules apply?
What are the cons and pros of this project, I
have never heard of anyone doing something
similar?
Your educated opinion on this matter is highly
appreciated.
Thank you in advance.
cheers

Elmar,
What seems to be the problem with the engine driven compressor? It is a
very reliable and efficient system. Tell your friend to contact either
by phone or off list and I will try to help him.
There are several Yak 52TW's that have electric and air start. Most of
the owners use the electric start to start the engine and use the air
start as a backup. George Coy at Border Air in Swanton, Vermont may be
able to help him with an electric start, should he decide that is the
way he wants to go. The electric start 52TW's are sometimes and
affectionately called "sissy yaks".
Naturally, it will add weight to the nose because the electric starter
and mounting assembly attaches at the nose case and adds a flywheel
between the nose case and the prop flange. He will also have to add the
battery and necessary heavy duty cables. Most import is the nose case
itself. It must be a series II nose case with the round accessory plate
on the left side. A series I nose case does not have the accessory
plate and therefore would have to be changed to a series II. May be
more than he really wants to do. Especially when it comes to changing
the nose case, should it be necessary.

Elmar,The idea is a good one if you have a lot of time and a big battery. As with most high pressure compressors these compressors pump very slowly. I found that I had to install a converter to convert 110 volts AC to 24 volts (at)20 amps DC to produce my high pressure shop air to check valves etc. I also tried a pair of heavy duty deep cycle 12 volt batteries but found that when operating under any pressure at all the compressor sucked the batteries dry before my CJ tank was full.

I have, what I'm told is an AN2 engine driven compressor. Mine is larger than the stock M14P compresssor. Besides making air at idle, I can have an empty bottle to the point of fill while taxing. I tend to like it.. Attached is a picture.

The air system will look cheap compared to changing over to electric start.
The gill system is also in the way, flywheel,crankshaft, maybe prop, starter, mounting brackets,the rest of the electrical system changes. keep the original air pump.

I did some research and confirmed that this compressor does indeed spec
out with a 21 Amp DC current draw at 27 VDC.
Assuming the original Russian generator is used, it can indeed handle
this kind of load. However, since this is a homebuilt aircraft, we have
to assume the electrical system is also homebuilt. We would have to
specifically know what kind of ancillary control system was used, such
as reverse current relay, etc., etc. It is doubtful that the complete
Russian system was used, thus I am guessing it might be an aftermarket
alternator system such as the B&C SK-35, etc. Need to know ALL about
that aspect of his aircraft.
We also do not know what kind of pneumatic tank was used, and the volume
of that tank. Using an overly large pneumatic tank in the homebuilt
design could indeed lead the owner into believing that the engine driven
compressor is "just not doing the job". Why? Because an overly large
tank would take one heck of a long time to come up to pressure with the
engine driven pump. This is a critical design consideration and could
be the root of the perceived problem.
As Doug Sapp points out, a 21 amp current draw for any period of time is
going to suck down the batteries in very short order. Typical
aftermarket Yak, Sukhoi, CJ-6 designs use two 12 volt batteries (in
series) of relatively light design that have between 6 to 12 amp hour
loads. These are way too small for this kind of continuous load, as
Doug mentioned.
So the idea is sound, and it will work, but it will require some pretty
extensive design requirements of the aircraft electrical system and the
aircraft battery.
As Dennis pointed out, the aircraft compressor works, and usually works
very well with minor preventative maintenance. It will (however) leak
and not work properly if it is not installed and checked properly.
Banjo fittings, crush washers, check valves, etc. All need to be
properly checked and tested, which is exactly what I am sure he wants to
talk to the gent about.
But before all that, and before electrical changes, and electrical
starters, etc., are all considered... ask this gentleman what the size
of his air tank is ... as in... what is the volume of his tank?
Especially as compared to the ones typically used in stock M-14 powered
aircraft.

My advice is to keep it simple. A pneumatic start system on an engine that is designed for pneumatic start is going to be far simpler than retrofitting electric start. The added weight alone for electric start would give me pause.
My recommendation would be to have your friend give Dennis a call as Dennis has already offered his assistance. It has to be a lot easier to fix what is broken rather than to start with something completely new and then have a completely new set of problems to troubleshoot.

Dennis & Doug are correct about the time a Cornelius 3-stage 1500psi 27VDC compressor would take to fill a tank. I use a 28dcv battery charger to run my cornelius and it takes 2 hours to fill a scuba tank to 1500psi. No a/c battery will last long enough. It'd be best to find out whats wrong with the regular compressor and fix it. A cornelius requires a oil supply (the can attached) and over all its heavier. I used mine to keep a scuba bottle filled for shop work and to refill my CJ during shop maintenance.
I am interested about the AN2 compressor. Does it fit right on the M-14 in the regular place? This is the first I've heard of it.

Group,
I looked at the Bear 360 project which has an M-14P with electric start
and Sukoi type shutters.
Skip Holm even asked about using my Yak-52 to help get the system up and
running.
But the project has not gone any further.

the compressor sucked the batteries dry before my CJ tank was full.

The other day I had a chat with a friend who
owns a M14P powered homebuilt.
He told me he doesn't have much luck with
with the original engine driven compressor
and is now thinking about removing and replacing
it with a Series 32 Cornelius 3-stage 1500psi
27VDC compressor (installed in the rear part of
the fuselage).
He has no retractable undercarriage and no
pneumatically operated flaps and brakes,
his air system is only used to fire up the engine.
I suggested to convert to an approved electric start
system but since he has already that surplus compressor
(and a skinny wallet), he would like to give it a try.
I am always very skeptic if someone deviates
from the designer's path, but since this is a
homebuilt - different rules apply?
What are the cons and pros of this project, I
have never heard of anyone doing something
similar?
Your educated opinion on this matter is highly
appreciated.
Thank you in advance.

Thank you everybody for your
input and for sharing valuable
thoughts and information.
Dennis, I will forward Thom your
phone number - thank you for
your generous offer to give him
some guidance.

Elmar
P.S.: Last month I have sold my spare
compressor but I've learned today that it
also fits on the M14P, timing is everything
in life.

It's a little larger but still fits as an exact bolt-up. Mine is canted downward instead of the stock upwards due to hoses that I added.

Jim:
Nice to see you at Ken's service. Since then I am recovering from colon cancer. The surgery went well, however, Halifax Hospital did their best to kill me. Checked in feeling great and 170 lbs.: checked out a skeleton at 132 lbs. Had 24 hour home care, now, much improved and up to 150 lbs. This note is a suggestion to enjoy every sunrise. Hope you and your family is well and happy.

We have an AN2 compressor for the ASH engine. (AKA a Russian License built 1820 Wright). We also stock new AK50 compressors.

As with most high pressure compressors these compressors pump very
slowly. I found that I had to install a converter to convert 110
volts AC to 24 volts (at)20 amps DC to produce my high pressure shop air
to check valves etc. I also tried a pair of heavy duty deep cycle 12
volt batteries but found that when operating under any pressure at all
the compressor sucked the batteries dry before my CJ tank was full.

The other day I had a chat with a friend who
owns a M14P powered homebuilt.
He told me he doesn't have much luck with
with the original engine driven compressor
and is now thinking about removing and replacing
it with a Series 32 Cornelius 3-stage 1500psi
27VDC compressor (installed in the rear part of
the fuselage).
He has no retractable undercarriage and no
pneumatically operated flaps and brakes,
his air system is only used to fire up the engine.
I suggested to convert to an approved electric start
system but since he has already that surplus compressor
(and a skinny wallet), he would like to give it a try.
I am always very skeptic if someone deviates
from the designer's path, but since this is a
homebuilt - different rules apply?
What are the cons and pros of this project, I
have never heard of anyone doing something
similar?
Your educated opinion on this matter is highly
appreciated.
Thank you in advance.
cheers

A few facts to consider:
AN-2: 4700 pound aircraft with a 1000 horsepower engine. Pneumatic brake system and compressor designed to bring it to a stop.
Take air compressor off 1000 HP engine and put it on 360 (or less) horsepower engine.
It fits.
Pumps up tank faster. You betcha. Which means it also places a much heavier load on the engine drive system that powers it while doing so.
The result of doing that long term? I have no idea. Maybe someone else does. I have no doubt that it works well short term. It may turn out to be a really good mod, but make no mistake that it will rob more power from the engine when it is under load. Not saying the sky is falling. Just saying that it is wise to consider such a change carefully.

Unload it while flyin. Save wear and tear on any compressor.

Bill,
Unloading while flying not a bad idea to avoid continuous load when tank is
full but I am guessing that it would still load the drive system while
filling the tank and if nothing else I is will surely take more energy
(horsepower) from the engine even when not under load than a stock
compressor with the same mod... May not be much I just don't know.
Nifty install though.
