Subject: | bends for oild pipes & fire proof |
as a consequence of adding an oil thermostat to my build with a 912ULS I need to
make a couple more bends in the oil pipe. I have looked for standard bends that
I could hose clip to but not found anything. Whats the best solution - buy
some alu pipe and a bender? if so any suggestions welcome.
On a similar subject its it mandatory to fire sleeve fuel pipes on the UK version.
My C42 doesnt have it, my engine supplied via Europa doesnt have it and Skydrive
UK say they dont recommend it as its no longer possible to inspect the
pipes. A would be comfortable without sleeving.
Thanks

Subject: | place for venturi -in air duct? |
I am planing fitting a venturi to drive a vac AH & DI has anyone any suggestions
as to the best place to put the venturi. I am tempted to put one or two smaller
ones in the bottom of the air duct under the prop as I have a few inches space
under the radiators.
I am also tempted to ditch the heavy vac instruments and fit a trutrak AH/DI

Europa's Rotax engine manual tells you to protect against vapour locking by fitting
insulating firesleeving forward of the firewall. That makes it mandatory
in the UK.

Subject: | place for venturi -in air duct? |
Graeme,
I thought we had left venturi's in the history books. My experience with
them goes back to Luscombes and Austers. They were always rather dudious
bits of kit that only work at all, at reasonably high speeds. That was when
they were fitted externally on the wing L/E or side of the fuselage. In
this position they create significant drag.
As you intend fitting it/them within the cooling duct be aware that on the
basis of 'not getting something for nothing' you will be interfering with
the engine cooling. Though I have not seen actual pictures of it you will
find that the flow lines within the air intakes under the engine will be
very turbulent which will not be appreciated by a venturi which relies on
smooth or even laminar flow to work well.
I personally think you would be much better off with a new fashioned Vac
pump or all electric/electronic instruments.
Just my input for further comment.
