Acquisition from Spain of five 150hp Hispano-Suiza eight-cylinder Vee-type engines prompted the Norwegian Army Flying-Service (Haerens Flyvevaesen) to order the design of a single-seat fighter around this power plant.
Design was begun by Ing Hellesen at the Kjeller Flyfabrikk in the autumn of 1919, by which time the requirement had changed to that of a two-seat fighter-reconnaissance aircraft. Of wooden construction with a plywood monocoque fuselage and designated FF 6 by the factory and T.2 by the Army, the prototype was flown in 1921.
It immediately displayed unacceptable characteristics which were exacerbated by the fact that the Hispano-Suiza engine was found to develop only 103hp. A max speed of only 100km/h was attained compared with an anticipated maximum of 132km/h. Further development was therefore abandoned after the first test flight.
Engine: 150 hp Hispano-Suiza 8 Wingspan: 11.75 m / 39 ft 7 in Length: 7.25 m / 24 ft 9 in Height: 3.57 m / 12 ft 9 in
The Hærens Flyvemaskinfabrikk Aircraft FF.4 was an improved version of earlier series of 1920 Farman developments. Five were planned, but the prototype proved a failure.
In 1860 Belgian Etienne Lenoir patented a gas engine fuelled by coal gas. Paul Haenlein employed a four-cylinder Lenoir engine producing 5 hp in his airship at Brunn in 1872.
The airship’s varnished silk envelope was filled with coal gas, which supplied the engine at a rate of 250 cu.ft of gas per hour, turning a large propeller at 40 rpm. Internal pressure was maintained by a ballonet supplied with air rom a mechanical pump, fitted to compnsate for the coal gas burned in flight. During the first trial at Brunn in December 1872, perceptible control and a degree of acceleration were evident, with the craft achieving 11 mph.
Despite the initial success of this and further trials, the early Lenoir engines suffered from a poor power-to-weight ratio and low power. Haenlein eventually abandoned his work, frustrated by the lack of suitable engine.
Envelope capacity: 72,000 ft Length: 150 ft Diameter: 30 ft Height: 44 ft Gross lift: 2.1 ton Disposable load: 0.30 ton Engine: 1 x Lenoir 4 cyl gass, 5 hp Speed: 11 mph Range: 10 mi Crew: 1
The Hackenberger 1A is an evolution of the model H. Similar in its design, but larger and more streamlined.
Built in 1935, the single place 1A extremites of the elevator had twin stabilizer/rudders.
Those rudders were actually braced onto the rear of the fuselage and only a single strut balanced the elevator above the stabilizers. The fuselage curved upwards at both ends, connecting to the leading and trailing edges of the parasol. Somehow the angle of the elevator was varied at its joining with the parasol/fuselage.
Registered N13974 c/n 2, power was two 20hp Irwin Meteormotors, changed to 40hp Continentals in 1938.
A 1930 twin-engine flying pancake-type with heart-shaped parasol wing built by A L. Hackenberger. The Hackenberger H, or Helioplane, was powered by two 4-cyl “Scroggies”.
The aircraft was registered NX18966 c/n 5H-1 (as H) as a single seater.
Designed by Satoru Shinohe, the OpenSky M-02 glider/jet-powered motor glider is based on the ‘Mehve’ glider seen in the 1984 anime film, directed by Hayao Miyazaki, Nausicaä of the Valley of the Wind. In the film, Nausicaa takes flight uses the Mehve – the name taken from the German “Möwe”, meaning ‘gull’ – to survey a toxic wasteland.
The M-02J is the work of Kazuhiko Hachiya, who has been working to produce a pilotable version of the aircraft since 2014. Like the animated version, Hachiya’s craft is built around a small jet engine, which is used to achieve take off, climb for a duration of 10 minutes, and attain gliding altitude.
Hachiya’s Mehve, called the OpenSky, has been through several versions since 2003. The original version was radio-controlled, but Hachiya himself took to the sky on OpenSky 3.0. It was this model he planned to show to the public.
The craft boasts a 963cm wingspan and a 267cm fuselage. Like in the film, the pilot lies flat against the top pf the vehicle, and steers by shifting their weight around.
As of June 2006, two aircraft prototypes had been constructed, and one has successfully completed a series of 10 unpowered test flights where it flew 98 meters and achieved an altitude of 4 meters after being tow-launched by a tensed elastic cable. The project is led by artist Kazuhiko Hachiya and design by Satoru Shinohe and manufactured by Aircraft Olympos.
The Jet engine installed version, M-02J, had public demonstration flight in June 2016 at Takikawa, Hokkaido. Hachiya – a pilot and artist, who conducted the flight in a helmet decorated with wings – hoped to improve stabilisation for future efforts.
Variants:
Möwe 1/2 (メーヴェ1/2) — sub-scale, radio-controlled development aircraft
M-01 — unpowered development aircraft
M-02 a total of 2 airframes of M-02 were built, 1 for preliminary gliding practice and 1 for installing Jet engine with no intention to mass-production.
M-02J (14 June 2007) Modified M-02 airframe has had a Jet engine installed. (14 April 2010) Vehicle M-02 has undergone high speed taxi tests at Fukusima Sky Park runway, in order to evaluate stability and acceleration. More details of the jet engine assembly are available, and the engine has a considerable separation from the walls of the engine pod, in order to permit better cooling and prevent the wood and composite airframe from encountering an excessive fire risk.
