Well whats the deal with the airconditioner??? I responded offline as
requested and also posted here for info, with no response.
While I'm on the subject. I've come up with another idea for AC. While
I was at SAM's club the other day, I noticed this little bitty 5200
BTU window unit which only draws 4.5 amps and weighs around 45 lbs.
The unit is assembled in 2 halves and looks like the
compressor/condensor unit is in the rear half, and the evaporator in
the front. Most window units have 2 fans, one for the evaporator and
one for the condensor. It sounds feasible that the
compressor/condensor section could be mounted in the radio bay in the
nose, and the refrigerant lines could be led through the bulkhead to
the evaporator unit in the cockpit. The unit costs $90, a 24v to 110V
900 watt inverter is another $100. You would just need to install a
couple of relays so you can remotely control power to the inverter and
to the evaporator fan in the cockpit (you would need to run 110vac
through the bulkhead into the cokpit to power the evaporator fan).
Total cost of parts would be under $500.
Since the recent post was for a 5200 btu AC unit and mentioned
inverters, sounds to me like someone came up with this idea already.

It turned into "Big Business". He has a manager handling the sales and tech

I mentioned the same possibility of using this window unit in my Mustang II
experimental. I'm no electrical engineer so don't quote me on this as I
probably have it all backwards, but something about the amps that unit pulls is
at
the AC 110volt setting. It would supposedly pull more like 60 amps DC? Your
L-29's may easily handle this, but that's pushing most DC alternators...

Not at all. You need to just use OHM's law and convert to power, 4.5
amps @ 110v = 495 watts, P=E x I ...conversly I = P/E so 495 watts
divided by 24v = 20 amps at 24V. For startup current just double that
value and that ups the startup current requirement to 40 amps, add 10%
for Inverter inefficiency and you're in the neighborhood of 50 amps
for startup, and about 25 amps while running. The inverter I saw for
$100 was rated at 900 watts continuous with 1800 watts peak, more than
enough for this application. I've never seen these tiny window units
before, thats why I never considered using window units, but the
weight and current draw of these little babies makes them viable.
Also remember that the alternator need not be able to keep up with the
momentary startup current requirements, since the battery will act as
you current storage tank, the alternator just replenishes the current
during continuous use. Even a 30 amp alternator would be able to
supply 5 amps of charging current during continuous AC use, but I
wouldnt recommend doing this with anything under a 50 amp alternator.

Ernie, I recently bought one of these units when my heat pump at home
failed. If memory serves the box advertised it weighed 40 pounds. It may come
in at
less than that once you strip it of it's current chassis, and reconfigure to
fit into the L-29. All food for thought huh?

Reviewing some of the conversations we had on the Mustang site on this
topic, another consideration that was brought up a couple times is possible
interference between an inverter and the avionics....On a positive note, it could
be run on the ground from a normal 110 plug in. Get the plane cooled down
without draining the battery!

I think the inverter numbers are a bit off. here is the formula for power
invertes. This is for a 24v to 110/120 inverter
Here's the formula for all power inverter: Amps (needed) x (volts)110 V AC
wattage of inverter needed
50amps needed for start X 110v =5500 watt inverter. I have a 1000 watt
inverter and it does not run much let alone a small AC unit. The inverter
needs a lot of air(on the ground is the only time this would be an issue) or
it will overheat and trip fast.
sure would be nice to have it though. I would also go as far as to put a
small boat type halon system in the nose if that was the place I vould run
have the compressor. Again big heat producer and they are not ment for
closed spaces. just my 2 cents.

Hi Ernie,
Sorry about the delay getting back to you. The full time flying job is the
one that pays the bills and I've been busy with United. Then got side
tracked with getting checked out in a L-39, which solves the AC problem as long
as
I don't go back and fly my L-29. LOL>
I'll email you directly.
Thanks.

Hi Ernie,
Sorry about the delay getting back to you. The full time flying job
is the one that pays the bills and I've been busy with United. Then got
side tracked with getting checked out in a L-39, which solves the AC
problem as long as I don't go back and fly my L-29. LOL>
I'll email you directly.
Thanks.

Hi Bill,
Speaking of Red Tape, you coming to Reno Air Races. I most likely will be
doing an engine change on my L-29 and any extra bureaucracy "help" would be
welcomed.

Hey guys,
Thought I would post a question.
My engine temps are quite good, but I don't develop the thrust/speed that my
compadres possess during formation takeoff and also at formation cruise.
At cruise in formation with EGT's matched I am turning about 4% more
indicated RPM than my fellow L-29 buddies. i.e. I'm at 94% and they are at 90%
with
matched EGT and matched speed.
I have talked to a few different guys and also a warbird shop on the field
here at Reno, Stead and I have got a range of input on what to do such as:
1. Adjust the fuel controller to deliver more fuel since temps are good .
2. Wash the turbine blades
3. Put a smaller Nozzle on
4. Replace the engine with a factory zero time overhauled engine.
Anyone else encounter this situation or have any suggestions.
Thanks,
Scott

I had a nose gear problem in my L-29 this weekend. A problem all of us can have
due to a design flaw. Simple fix though. Will type up what happened and post
it here and the CJAA web site tomorrow morning. (with photos) At work now and
not enough time to type it up.....All ended up well though when I hit the mains
down hard and got the nose wheel to lock before setting it down....

Hey guys..I have a couple minutes so I will give you a quik run down with full
story tomorrow...
The four bolts/nuts that hold the nose gear door to the rod that connects to the
nose wheel can come loose. Mine are flat head rounded tops that go through
the door and through a rubber piece then with a thin metal plate held on by four
6 mm nuts. The metal plate bends up on the corners to hold the nuts. the
problem is that this does not keep the screws from backing out as I found out.
I had check it in preflight and all was well. in flight one nut came loose
so when my front wheel tried to come down the bolt, which is about 2.5 inches
long came out but not all the way so it prevented the door from opening all the
way which inturn kept the nose wheel from locking down. will post complete
story tomorrow with photos...

Along that line, do any of you guys know what the equivalent horsepower
the L-29 engine is putting out at cruise, say? I know it's not a direct
comparison, yet crossover formulae do exist -- I just don't remember
them :)
Thanks,

| Subject: | Re:nose gear problem |
Just got another break so here is a bit more of what happened...
Coming back into land. Gear down got green on the mains nothing on the nose. Tried
a few more times cycling the gear while resetting the day switch, circut
breaker etc. No luck. Tried pulling some G's (4) to swing the nose gear down
with no luck. finally blew the gear down and still didn't have green light or
proper stripes on the barber pole (missing one), flew by the airport had somebody
on the ground give me a visual inspection who said gear didn't look down
all the way. decided to hit the mains hard to see if it would knock the nose
wheel into place, which it did. Upon exiting the a/c, I discovered the bolt
sticking out of the door jammed against the bottom of the a/c which prevented
the door from opening all the way and thus preventing the gear from locking down.
I had checked the door before take off in the preflight and all was well.
My fix was a lock washer, locking nut then also safty wired (just through the
ends of each bolt to each other. Will post a photo
tomorrow of it. Check your a/c and see if this is the way your nose gear door
is. Like I said in previous post, the metal tabs bent against the nut don't
keep the screw from undoing itself, just the nut!!! Greg

Does the engine gives 100% at full throttle ?
What is the EGT at full throttle ?
What is the fuel pressure at 100%
Does the runway take off lenth seems normal ?
May-be you have to adjust the fuel controller to deliver less fuel
