→Airbus Perlan Mission II: Correct typo |
||
Line 79:
A great deal of design work has been done by Greg Cole of [[Windward Performance]] to show that a sailplane for 90,000 feet is relatively straightforward, while 100,000 feet is possible, although more difficult and expensive. Windward Performance would build the sailplane of high performance pre-preg in production-quality tooling. The sailplane required relatively high-end design, analysis, and construction to be flutter-safe at very high true air speeds, and strong enough for the potentially heavy turbulence that could be encountered at 90,000 feet. It must also have well-proven, fail-safe pressurization and cabin air re-cycling systems.
In 2014, [[Airbus]] agreed to become the title sponsor, and provide sufficient funding for completion of the aircraft, flight testing and the altitude flights. The mission
[[RDD Enterprises]], an aviation research, design and development company based in [[Redmond, Oregon]], took over the manufacture of the Perlan 2.
