AK-X swept wing sailplane
Not much happening the past two years?

AK-X swept wing sailplane
A couple of additional videos have been posted to their YouTube channel in the past year, including a rod control stress test last month,

Just another waste of time and effort on the flying wing concept, and as usual, it will be worse than a normal sailplane of the same span area.

Thank god all the US-based AKAFLIEGs concentrate on solving real problems and are delivering only concepts which can be commercialized right away and thereby assure the survival of the vibrant domestic glider manufacturing base.

Students pursuing the same thing the manufacturers are pursuing seems a like bigger waste of time and effort. They are supposed to learning, and working on difficult problems without the need to be profitable sounds like a good way to achieve that learning. -- Eric Greenwell - Washington State, USA (change ".netto" to ".us" to email me) - "A Guide to Self-Launching Sailplane Operation" https://sites.google.com/site/motorg...ad-the-guide-1 - "Transponders in Sailplanes - Dec 2014a" also ADS-B, PCAS, Flarm http://soaringsafety.org/prevention/...anes-2014A.pdf |

Hi Eric You have to think about this in the context of the German education system. These projects are not part of the formal syllabus. They are voluntary, additional projects. The best compete to be able to participate in the AKAVlieg programmes, where they get to apply their coursework to the practical industrialisation - DesignBuildEvaluate of their ideas. Consequently they turn out engineers with decent practical experience in leading edge manufacture. Not a bad approach - especially considering the direct engagement with peers, and product manufacturers, and academics. These engineers and scientists also get to test their product. Good for focussing the mind. I doubt there is any pressure, expectation or ambition for their experimental design to be a commercial success, Or even necessarily to advance flight performance. It may be primarily about fabrication techniques. This one could well be about controlability... Who knows. Empirically he approach seems to work. The most recent, successful startup in glider manufacture -Jonker Sailplanes uses exactly this model. Bruce |
