The Concept

Posted 02-08-2013 in Articles by Christopher

This site was established to support the development of the worlds first Open Source manned aircraft. Through the generosity of the family of the late Charles Ligeti, and the active contribution of his son Ron, an accomplished aeronautical engineer, the Ligeti Stratos has been made available as what is hoped to be the first of a complete line of Open Source aircraft.

The second generation Ligeti Stratos Project has five objectives, the first of which is to create a complete set of aircraft construction plans and a “51%” parts kit. Distribute the plans at no charge. Make materials and kits available through 3rd party commercial suppliers. Create and cultivate a community of technically-proficient participants and supporters.

History

Posted 02-08-2013 in Articles by Christopher

The all-composite, joined-wing, ducted fan Ligeti Stratos was originally conceived in 1982 by Charles Ligeti, of Australia. The joined-wing layout was first demonstrated in a hang-glider which was entered in the "Bird Man Rally". In 1983, a variety of free flight models and a radio-controlled quarter scale model were built. The project was moved to a hangar at Essendon Airport, Victoria, and Charles hired several people to help produce the aircraft. The first full-sized Stratos prototype was built between 1984 and 1985. Charles Ligeti made a 45 minute first flight on 25 April, 1985. He reported that the aircraft had exceeded his performance expectations.

Team - Suppliers

Posted 02-08-2013 in Articles by Christopher

One of the main objectives of the Open Source Ligeti Stratos Project is to encourage the participation of commercial interests in the project to make engines, instrumentation, assemblies, materials and services available to individual builders through a coordinated supply chain. Pricing will be set by the suppliers. Most components will be sourced by multiple suppliers.
