Ö 9 -ASJA typ 2 - Swedish Air Force Advanced Trainer Aircraft

ASJ at Linköping had since 1907 manufactured railway cars. ASJ stands for ”AB Svenska Järnvägsverkstäderna” - in English ”the Swedish Railway Workshops”. In 1930, ASJ decided to build aircraft. A new company, ASJA (AB Svenska Järnvägsverkstädernas Aeroplanavdelning) was founded, which later became incorporated in SAAB.
The first military design of ASJA was a two-seated advanced trainer, ASJA typ 2 (L2). Two aircraft was ordered by the Air Force in 1931 and got the designation Ö 9.
The aircraft, although the engineers of ASJA adapted many ideas for their design from Fokker, Phönix and Heinkel aircraft in Swedish service, did not perform very well. ”Heavy and clumsy” is one judgement.
The first aircraft, fitted with wheel landing gear, were delivered from the factory in August 1932, but was not approved by the Air Force until November. It was intended for the War Flying School F 5 at Ljungbyhed, but it became based at Wing F 1 at Västerås, where it was given the Air Force number 1602. The second aircraft was equipped with floats and provided to the naval Air Force Wing F 2 at Hägernäs. Air Force Number 2601.
The two machines were used for general flying training during the thirties. 1602 was written off after a crash in 1937. 2601 existed until 1940, when it was written off due to wear and tear. The aircraft had a welded, fabric covered steel tube fuselage. The wings were of wood, covered with fabric. Metal turtle deck and nose covering.
The Ö 9 was equipped with a Wright Whirlwind engine type R975E. This 9-cylinder air-cooled radial engine developed 330 hp. The oil cooler was fitted beneath the nose of the aircraft.  
Length: 9,25 m. Span: 12,60 m. MTOW: 1.960 kg. Max. speed: 175 km/h.
