Was wondering if anyone has figured out a good air exit vent for a glider with an engine box i.e., ASG-29E, ASW-28E, ASW-24E, Nimbus 4T...

The producers of the ES Vent, which is commonly installed in 24's, 27's, 28's, and 29's, as well as a hand full of other types, have looked at the issue of installing a vent using the design principles that work well in the above in the 29E and similar gliders. All of the Schleicher motorized gliders that have fuel tanks in the baggage compartment share 2 issues.
1. The aft bulkhead in the baggage compartment is a bit too far forward to allow placement where experience with the other similar types shows it should be. This would require a very special vent that would have to have alteration to the bulkhead. This is something we do not think is wise as it is important structure. Even if we could engineer this, and get approved by the factory, the installation would be very complex.
2. To create a collector to lead into the vent smoothly would require alterations to the fuel tank. We aren't going to do that for reasons described above.
As of this time we do not yet have a practical solution for these gliders.
