Combat Warplanes / Svenska Aero Jaktfalken
« on: June 09, 2008, 01:01:35 AM »
Svenska Aero Jaktfalken ("Gyrfalcon") was a Swedish biplane fighter aircraft, constructed in the late 1920s. The aircraft was first manufactured by Svenska Aero and later by ASJA.

History

The Jaktfalken was constructed and manufactured by Svenska Aero as a private venture. The company contacted the Swedish Aerial board, requesting guidelines and wishes for a fighter aircraft. When no reply was received, Svenska Aero began to look at foreign designs to get some guidance. Jaktfalken was a conventional biplane equipped with an Armstrong Siddeley Jaguar 9-cylinder radial engine. The landing gear was fixed and there was a sour under the tail section. The fuselage skeleton was made of welded beams covered with fabric. The fore and aft part of the fuselage was covered in aluminum sheet. There was a fuel tank between the engine and the cabin, which contained enough fuel for 2,5 hours of flying.

The Swedish Air Force test pilot Nils Söderberg was given the mission to try out the new prototype at the Barkarby air force base. After one of his landings he said "this is the best aircraft that I have flown so far".

On November 11, 1929 the Jaktfalken was presented for representatives from authorities and the press. The Swedish Air administration decided that three Jaktfalken and three British Bristol Bulldog II fighters were to be ordered for comparative tests.

The prototype was bought by the Swedish Air Force on January 9, 1930 and given the designation J 5. By February 1930, the Air administration decided to use a Bristol Jupiter engine as the air force standard engine. The designer, Carl Clemens Bücker was forced to modify the two ordered aircraft, by making new engine attachments and make modifications to the fuselage. These aircraft were given the name Svenska Aero Jaktfalken I (or J 6 in the Swedish Air Force). The order was followed by a new one for 5 aircraft with Jupiter VII engines in 1930. During test flights, powerful vibrations were encountered. Both Svenska Aero and CFV tried to solve the problem, without success. The aircraft was still approved by the Swedish Air Force. Bücker and CFV tried to modify the landing gear and the fuselage after the delivery. The aircraft had now a more angular fuselage and the Jupiter VIIF was chosen as the engine. The Swedish Air Force received three Jaktfalken IIs in 1932.

Svenska Aero tried hard to earn export orders for the Jaktfalken. Military representatives from Argentina and Japan came and tested the aircraft, but no orders followed. The only export order came from Norway, who ordered one aircraft in 1931, equipped with an Armstrong Siddeley Panther IIIA engine. This aircraft was used as a comparative aircraft against a Hawker Fury. When the Swedish Air Force wanted an additional seven aircraft in 1933, Svenska Aero had been bought by ASJA and the deliveries come from the new manufacturer, who made some minor modifications to the stabilizer and the windshield.

Versions

    * SA 11 Jaktfalken - Prototype aircraft, equipped with an Armstrong Siddeley Jaguar engine. One was delivered to the Swedish Air Force as a J 5.
    * SA 14 Jaktfalken I - A modified fuselage with a Bristol Jupiter VI engine. Seven were delivered under the designation J 6 to the Swedish Air Force.
    * SA 14 Jaktfalken II - A modified fuselage and landing gear with a Jupiter VIIF engine. Three were delivered to the Swedish Air Force under the designation J 6A.
    * SA 14E Jaktfalken II – Similar to the SA 14 Jaktfalken II, but equipped with an Armstrong Siddeley Panther IIIA engine for Norway. One built and delivered.
    * SA 14 Jaktfalken II - Produced by ASJA, with a modified stabilizer and windscreen. Seven were delivered to the Swedish Air Force under the designation J 6B.

Operational history

Use in Finland

Sweden gave three Jaktfalkens (two J 6Bs and one J 6A) to the Finnish Air Force in December 1939. These were the oldest ones of the type that Sweden had, and it was common to give away the oldest equipment as military aid. The aircraft were used for training at the airfield at Kauhava until 1945 when all were scrapped.

Use in Sweden

The aircraft was to be called J 6 in Swedish service. After the Swedish Air Force had bought a Svenska Aero Jaktfalken J 5 in 1940 the Flygstyrelsen (Swedish Air Board) to use a Bristol Jupiter as the standard engine.

Two J 5's were already ordered, but not ready for delivery. The designer, Carl Clemens Bücker, was forced to reconstruct the aircraft from the firewall forward to make room for the new engine. The modified aircraft was given the designation J 6.

Svenska Aero wanted more orders of the type in order to bring down the cost and to rationalize the production. The flygstyrelsen therefore suggested that another four J 6's should be bought for the Swedish Air Force.

The first J 6 was flown on 1930, at the test flight, the aircraft suffered from heavy vibrations in the tail section. The aircraft was then transferred to the CFV where they tried to modify the construction to reduce the vibrations. Although the problems weren't solved by the modifications, the aircraft was approved by the air force.

The third aircraft was ready in the autumn of 1930. This aircraft had similar problems with vibrations as the first prototype. The aircraft crashed during the first flight and the test pilot died. This test pilot was Einar Lundborg, a national hero, who had rescued the Arctic explorer Umberto Nobile. The accident caused a major storm against the leadership of the Swedish Air Force. The accident was investigated by a commission. Two J 5's and five J 6's were transferred to the Swedish Air Force.

Bücker later modified the aircraft's fuselage, gave it a new landing gear and a Jupiter VIIF engine. The Swedish Air Force ordered 3 aircraft of this modified type and gave them the designation J 6A. These aircraft were delivered during the summer of 1932 and they were stationed at the F 3 Malmslätt air force base. All J 6's were transferred between 1932 - 1934 to F 1, in order to be used for fighter training.

Another 7 aircraft were ordered by May 1933 but the company had been merged in 1932 by AB Svenska Järnvägsverkstädernas Aeroplanavdelning (ASJA). The aircraft was thereafter produced and delivered by ASJA. As soon as the order had been received, manufacture began. The first aircraft was ready by November 1934. All aircraft were ready and were delivered by June 1935. The Swedish Air Force designated these aircraft J 6B.

When all fighters were transferred from the F 1 Västerås air force base (where F 8 had been an detachment) to F 8 Barkarby in October 1938, there were seven J 6's left in the air force, they were used as fighter trainers. Three aircraft were given to Finland during the Winter War 1939-1940, all the remaining aircraft were scrapped in 1941.

Swedish Air Force designations

    * J 6 - A J 5 with a Bristol Jupiter VI engine
    * J 6A - Modified fuselage with a Jupiter VIIF engine
    * J 6B - Produced by ASJA with a modified stabilizer and windshield.

Run Kilian Run.... to the toy store  :-green

Alright i will buy some tools now. A tweezers i have, a sharp knive (maybe thats not good to cut the plastic parts?). What i need to buy: glue, putty, colors, sandpaper. Colors i will buy probably in the internet or i will have to do it with revell colors. Anything i forgot?

Its perfect to start it. Bad weather came this night and its all dark outside.

Combat Warplanes / The identify the plane thread
« on: February 06, 2008, 03:45:52 PM »
I thought it might be useful to open such a thread if someone of our members has a photo in their collection and does not know which plane is on it.
I can say for myself it happens quite often for me  :-red

Today i had this one in the mailbox. I have hoped it could be a Sopwith 1 1/2 Strutter but im not very sure about it. Also i think its after war. The observer and pilot have some headsets on and the observer has something like an early radio or transmission device if i see it right  :-cool

Combat Warplanes / Lockheed F-104 "Starfighter"
« on: February 01, 2008, 01:33:10 PM »
Husband of my Dad's cousin worked at Messerschmitt and Heinkel where Starfighter was license produced since the 1960s. Starfighter was also called Widow Maker here because 292 of 916 of Bundeswehr Starfighters crashed or had accidents  :-eek

In this movie they say at times only 10% of a squadrons F-104 were ready because of lack of trained maintenance personnel, also you can see how hard it was to land this machine, pilot makes touch-and-go:

Maybe our friends from Holland/Belgium and Italy here can tell something about license production in their countries. Would be interesting.

Aircraft Modeling / Bf109 Revell Kit
« on: January 30, 2008, 12:36:16 PM »
Does someone have a Revell kit of the 1980s or early 1990s? If i remember it right there was a Legion Condor Markings 109 on the package with some yellow nose. I thought i had never build a model but then i rememberd that i build this as a kid without painting it. It was relative small scale, like size of my hand. I think i dont have it anymore.
