Competition preparation and sealing
« on: 14 November 2017, 09:23 »
Hi,

I'm looking into sealing a 15b better, eg, it has a noisy canopy, a cg hook and an aerotow hook, poorly fitting U/C doors, I might consider mylar seals on the ailerons and the rudder and so on.

Has anyone looked at or done similar work and could you give me info on how you tackled the work.

Thanks

John

Hi John,

I have mylar seals on ailerons and rudder with teflon sealing below it; standard fabric band (outer slots) and mylar (inner slot) at the gear doors.
In my opinion, tight sealing and mylar on the ailerons is an absolute "must have" on composite gliders, it defintely pays. Mylar is important preventing cross-direction airflows within the small gap between wing and aileron.

Please have a look here: http://www.streckenflug.at/shop/product_info.php?products_id=309&language=en
(scroll down for installation instructions)

For the cg hook I would recommend a flexible sealing made of kite-cloth on the inside. (I have only aerotow-hook, which I sealed by a flexible rubber plate with a slot in the middle on the outside; inside sealing made of kite-fabric is under construction ;-)

Best regards
Andreas
