High Altitude operations (Turbo charge???)

There used to be an add on kit that fed water vapor into the carb, which
increased performance. They used them on Spitfires during WWll and on
cars in the seventies. H20 = hydrogen and oxygen.

How about one of the new miniature turbine engines used on model
aircraft. Duct it so the exhaust would feed directly into the carb of
the main engine on take off and shut the turbine off for cruise. These
cost about 1500 bucks now and weigh about 10 lbs.

Uh, bzzzzt. No. How about the nearly no oxygen content the engine is
feeding the other engine. Besides for 1500 bucks, there are proven methods.

The 115 with 100% is close but how the hell do you get 105% humidity?

"super-saturated solution". Really.


In other words, it's raining. There is more moisture than the 100% that the
air can support and so it falls.

Hope this helps,

Better yet, feed in wood smoke, and you can spit two-by-fours out the
exhaust.
Water is hydrogen and oxygen that has already been burned.

Water injection is used to prevent preignition, though.

Water injection has been used for years to allow a motor to run with more
spark advance and or compression and or boost. Without the water, pinking
(or pinging, depends on what school you went to!) will occur earlier and
this limits the power of the engine without it self-destructing.

There are two schools of thought whether the water turning into steam inside
the cylinder is significant, and a search of the net will find several sites
that disagree.

Can be added to a car with a junkies needle (available free at your local
needle exchange) a bit of rubber tubing and a water container. Changing the
gauge of the needle allows different flow rates.

Hope this helps,
Peter

Yep.

When I had my Company in the Oil Patch and was inventing things in the
shop and patenting them.

You Worked?

Water injection in WWII aircraft engines was basically to prevent
detonation with high MP. Believe the Jug had it on their R-2800 P & W
engines. Could pull 90 inches with water as I recall???

Some early jets had water injection. Ferried a F-94A/B that had water.
Used on T/O and you used all to prevent any residual from freezing in
tamk and lines at altiude (-50 F).

Point of the sword.

Damn, why didn't I think of that? Now where can I buy one of those turbo
charged leaf blowers? I am tired of climbing on top of my high pitched roof to
blow pine needles and one of those should do the trick in short order.

How about building a 2180.

Personally, I'd not fly a turbocharged VW.

Ever.

into intellectual contests and/or berating others ideas?

I thought the weed eater / supercharger idea was novel as well as the
water injection idea. Why can't we continue with this brainstorming
without attacking anyone's ideas? How else can "crazy" ideas be explored
for practical application.

I saw a weedeater used as a "pony" motor to start a Lyc or Cont on a
aircraft that didn't have (want) an electrical system.

Sure beat hand propping.

Just my 2 cents. (I'm the "crazy" guy that's going to use a Turbo'd
Subaru in my "Fast Glass" kit. Isn't that what the E in EAA means?)

BZZZZZZT. No.

The water fed into engines is to cool the gas air charge, and keep it from
detonating, with really high levels of boost. Like over 100 inches of
manifold pressure.

This was used on many types of high performance applications today, and on
planes today such as at Reno.

Some current jets still do. KC-135 IIRC, and AV-8B.
Little bitta cooling, lotta extra massflow.
Different principle than water injection on
recips, but fun to use all the same. g
