.....
To join each stiffener to the canopy frame, use a 2 BID wrap-
around lamination from the inside skin of the frame to the outside
skin of the frame, with an overlap onto the frame of a minimum of
0.7". Grey tape may be used as shown to provide a cleaner edge for
trimming later. Flox is used where the stiffener meets the frame.
.....
The third stiffener is placed transversely at the aft canopy
bulkhead. Ideally, this third stiffener should rest on the top of
each side stiffener, and on the bottom of the aft canopy bulkhead. If
necessary, a small piece of foam can be used to accomplish this. This
third stiffener is likewise attached with flox and 2 BID tapes in a
wrap-around configuration.
.....
When completed, these stiffeners will form a very rigid box
around the canopy frame to stiffen up the entire assembly
considerably, as we'll as provide hard mounting points for the
hinges, pins, latches, etc.
