Hi Rowland
I worked with Nev on the original submissions to the LAA, Nev told me that
he had given them chapter and verse in the number of ply's and orientation
of them.
My involvement was mainly on the engine mount but I did supply Nev with
templates for the radiator baffles. I think you should contact Andy Draper
at the Laa for details of the layups
Best Regards

Hi Rowland
I will probably be going to the rally Saturday so can see you for a chat.
Those details you mentioned would be most useful . I will also study my xs
cowling as there shouldn't be much difference. The weight after all will b
e the critical consideration. Thank you very much for your reply.
Best wishes

Phil - glad to hear you are working with Jag. I promised I would bring some
of the offcut trimmed from the edge from my cowl to the LAA Rally and/or t
he Europa Club dinner so that Jag could see how thick it is. As you say, th
ere will be extra plies in some more high-stressed areas but I can=92t spea

e layup structure might be visible from the inside (which has no paint or g
el-coat). For instance, have a look at:
http://www.rowlandcarson.org.uk/aviation/europa_435/cowl_assemble_a.php
where although the angle is not ideal, I can see several places where an ex
tra layer or layers has been incorporated. If it helps, I can take better p
ictures next time I have the cowl off.

Hello All. Someone contacted me to request a copy of the guidance notes which I
wrote for the fitting the cowls. He stated a reason for installing them is that
they'll afford a 10 knot speed increase. I don't know where that idea came
from, but I can assure everyone that I haven't seen a single knot of speed gain
in the cruise.
Maybe there's some wishful thinking, which associates Nev's LoPresti style air
intakes with cowls having proper LoPresti design fitted to other aircraft types
and thus reducing cooling drag. I don't know!
My reason for fitting them as a replacement for my old Classic cowls was to improve
cooling and overcome hot starting problems. This goal was achieved admirably.
And they look good too!
