[FlyRotary] Re: Carlos' theory on
Nitros
I have been flying for 1400
with nitrous and its the only way I can get the coot out of the water,
I use it for about a 5 second burst to get it up on the step and may
give a longer burst if I need to get out of rough water or out a tight
spot, also use it to get a heavy load out of a short
runway.
Good explanation on wet and dry, I
use the wet system made by NOS.
Yes Bruce used it for the time to
climb and also Pushy Galore used it to set a altitude record of 32,000
ft with a 0-200, they used 10 lbs at a rate of 1 lb per minute,
actually made it to 34.000 ft but when the nitrous ran out the plane
stalled and he dropped to 32,00 ft to hold level flight to set the
record.
As for that blown up trunk there is
no way that nitrous did it alone as its just an oxidizer and is no
more dangerous than the oxygen bottle next to you for breathing, I
suspect he may have had a leaky gas can in that trunk with it on a hot
day and the blow off disk blew off and mixed with the gas to cause the
explosion.

The principle
difference between dry and wet Nitrous injection is that with the
"wet" kind you injected additional fuel along with the
nitrous input into the air intake. So the manifold is "wet"
with fuel. With "dry" concept, you pour
the nitrous oxide through the normal air intake and increased the fuel
through the normal fuel injectors by extending injector PW during the
Nox injection or turning on additional injectors. Since with
this approach the intake does not have fuel squirted (except through
the normal injector ports) the manifold remains
"dry.
Variations
abound but this is the basic conceptual difference between the
two. Some claim you need a mass flow sensor to do the
"Dry" approach, but that is not really correct, you just
need some means of sensing the onset of Nox flow and increasing the
fuel flow to match.
I was interested, but
after seeing what nitrous oxide can do (see photo of auto that
had a bottle in its trunk), I lost interest
{:>)

About the only thing I would consider it for is for a
quick boost on an amphib to get off the water or challenging Bruce
Bohannon to a climb contest.
Carlos was explaining the difference between wet &
dry nitrous injection which I still don't feel like I understand
well enough to explain myself.
I was trying to explain an idea I had for using the EC2 to
deliver the extra fuel required (via the EFI injectors) when
injecting NOX instead of using a separate gasoline injection port.
Not sure I explained it well enough for Carlos. It might not
even be a good idea. Goofs on laughing gas tend to be
expensive.

Tracy,
I walked up on a conversation between you and Carlos. Ya'll were
discussing Nitros in our applications. Can you give us a synopsis
of
the conversation. I picked up just enough to tell he was not for
it.
Please explain!!!
Bob
