I just read an artilce in April Kitplanes "Baffled by Baffles". One of the
things discovered after tufting everything including the intake for large
displacement aircooled engine was when pointed into the wind, even doing
run up there was absolute no airflow! They descided to not go flying till
they figured out why, and when headed back the second they turned
downwind, air began to flow (They had small camera able to view what was
going on). They began to fool on ground and sure as anything, no flow into
wind, flow begins when downwind. Conclusion was the prop was at more of an
angle of attack pointed downwind and was creating a larger low pressure
area.
Has anyone actual tried pointing downwind, versus pointing into the wind
when stuck on the ground for extended periods with a Europa? Does pointing
downwind yield lower temperatures?
Especial interested in results with monowheel with "Groundloop" adjustable
Airmaster prop (course and fine tested)?
Thx.
