Subject: | Re: Are Vne and Va IAS or TAS? |
Pete,
Quick answer:
During prop testing, I would do cruise tests up to 15k, then dive at Vne in
smooth air to the turbulent layer at 5000, then slow to below 130 of cours
e. No issues. (Did a loop at 160 just for practice.) Later to determine
prop pitch to hold 5000 and 5500 rpm, I shallow dived to Vne and observed
the rpm, landed, adjusted the prop course stop, and repeated.
The pitch and roll forces are a bit lighter at Vne, but still delightful.
Now you know why I'm a zealot about stab tightness, and flutter. I do this
type of testing on my new 914 / Airmaster powered planes I flight test.
By the way, in my last post, I didn't include wing flap vs local AOA change
resonance at high altitude in flexible wings of low elastic modulus. Nast
y stuff, and very lengthy to explain.
Keep it tight.
Regards,
Bud

Hi Bud,
Many thanks for your (as always) comprehensive post. Very much appreciated.
Your bolded statement implies that the Europa would be fine to be flown t
o VNE IAS at 15-18k (altitudes used by some Europa fliers) without risk of
flutter due to the relatively stiff construction (if I have not mis-read).
I'm quite hesitant to ever give that a try, but was searching for the comf
ortable TAS limits instead... which Ivan has appeared to answer with his pr
oven test numbers.
Now im wondering if any Europa fliers have become test pilots and flown at
VNE IAS higher than Ivan's 8000' during his Vd testing?
Just recently, another composite light sport didnt fare as well:

Subject: | Water cooler vs duct |
I have a set of Nevs cowlings, with revised radiator duct sides ( CD2&3), Nev acquired
for me a radiator with extra jackets to the side and side exiting hoses.
I have installed it which involved cutouts in the side panels, this means mounting
forward of the footwell. I now have not enough room between lower cowl
and the radiator, Ie negative by 10mm.
Has anyone fitted this sort of radiator? I am close to ditching it and fitting
the original standard, (does anyone have a spare?

Almost there, radiator and control set ups to go. 2018 might be the year.

Hi! Bob ,
Thanks for your message about my membership and communication. Which I have
misplaced !
I understood I would be contacted further as to what would happen about my
registration details and user name change . I don't recall getting any
instructions back but I cannot yet get access to the Membership page in
spite of renewing my password .
However this process requires me to use my user name , e-mail address AND
the pass word , I still need guidance please.
Regards
Bob Harrison.

Hi Alan,
I too have installed Nev's cowlings and I took his advice to fit the same water
radiator in the same position as found in the XS installation, but I also took
his advice to use the oil cooler from my original Classic cowlings. No problems.
Perhaps you could attach a few photographs to enable better understanding of your
set-up.
Thanks,
Jonathan
