In any case you will have a blind bonding applied to one side, be is spar
web to spar cap, or spar cap to wing skin - that's the backdraw of using
negative moulds.

Now if you produce voids in one case, you might as well produce voids in
the other case, no? And, by the way, how much would you allow the price of a
glider to increase in case the the manufacturer goes for x-ray or ultrasonic
QC?

Still, the use of
Graphlite rods instead of carbon fibre rovings, and externally built
spars which are then wrapped in fibreglass cloth and vacuum-bagged is
a method which produces stronger, more durable and longer lasting
wings. As the current fleet of German gliders gets older I'll wager
there will be a lot of speed limiting directives because the "margin
of error" isn't what they thought it would be.
What kind of spar construction methods do the SparrowHawk, Apis and
Russia gliders use?
