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. 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. The all-composite, joined-wing, ducted fan Ligeti Stratos was originally conceived in 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 , 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 and Charles Ligeti made a 45 minute first flight on 25 April, He reported that the aircraft had exceeded his performance expectations. 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.

Span: 17 ft 7 in 5. Remarks by Johan Visschedijk : "Charles K. Ligeti, a self-taught aeronautical engineer with a background in mechanical and chemical engineering, began design studies for a high-performance ultra-light aircraft of radical new design in Czechoslovakia in The single-seat all-composite joined-wing ducted fan Stratos micro-light was conceived in , to combine the efficiency of a canard, the large wing area and small span of a tandem wing configuration, and the strength of an externally braced biplane. The reductions in both weight and induced drag made the aerodynamically clean configuration suitable for soaring. Prototype construction was started in May , after extensive testing of the concept in quarter-scale radio controlled and free flight model forms, and it made a 45 minute first flight on 25 April , piloted by Mr Ligeti, who reported subsequently that it fulfilled or exceeded all performance expectations.

Ligeti Stratos

This aircraft was intended to be the production version of the "Stratos" aircraft. The prototype version had successfully flown some hours. These changes included the removal of the dihedral from the main wing and the use of full span elevators on the canard wing and full span ailerons on the main wing. The engine mounting was lowered such that the ducted propeller was totally below the main wing and the lower part of the propeller duct was extended well forward to form a "channel or strake". The main purpose of the "channel wing" was an attempt by the designer to lower the stall speed of the aircraft to 30 knots and to reduce both landing and takeoff speeds and distances. As far as the investigation could determine, the effect of these modifications had not been checked by wind tunnel or other methods prior to this flight. On the day of the accident the pilot and his assistants had worked at the factory preparing the aircraft for testing.
