The Árnason JFP-2S-8 was a 1990s Icelandic experimental aircraft that utilised jet flap technology. It did not fly.[1]
Design and development
Kristján Árnason was an aircraft engineer who designed and built the JFP-2S-8 to incorporate a 'jet flap propulsion' system he had devised and for which he had been granted a WIPO patent.[2]
The aeroplane was a high-wing monoplane, of canard configuration. Two intakes, positioned midway along the fuselage, fed air to two high-pressure turbines, powered by a pair of 52 hp (39 kW) two-stroke engines. The compressed air was then expelled out over full-span flaps that formed the trailing edges of both the forewing and the main wing.[2] The aeroplane featured a fully faired fuselage, an enclosed cockpit, a central tailfin, and a fixed tricycle undercarriage.[3][4]
Design commenced in 1975, construction started circa 1987 and was completed in 1996.[4][5] Both the aircraft's model name and its registration of TP-JFP reference its 'jet flap propulsion' system. According to Árnason, the JFP-2S-8 was the only aeroplane of its kind in the world.[6]
Operational history
In 1996, the aeroplane was displayed in a semi-completed state at the Reykjavík–Keflavík Airport.[6] During subsequent runway tests, it reached a speed of 40 kn (74 km/h), but could not take off.[4]
The aeroplane is currently on display at the Icelandic Aviation Museum. It had been delivered to the museum in 2013 using the Icelandic patrol boat ICGV Þór.[5]
