Alexander Schleicher ASW 28

The New Racing Class Glider

The ASW-28 is Schleicher's new high performance glider for the FAI-Standard Class. This glider incorporates the very latest technology, both in wing section and boundary layer control, and uses the most advanced carbon, aramid and polyethylene fibers in construction. The ASW-28 will be type certified for cloud flying and semi-aerobatics.

Current modern design theory leads us to examine the climb portion of the performance as much as the run part. This leads to a sailplane which will climb a little better and run a little better than current design. The ASW-28 will be lighter, more crashworthy and safer.
