With this aircraft, you will need to strike hard and strike fast. You'll have to since the Pyörremyrsky only has one spar supporting each wing making it easy to rip them off or be blown off by cannon fire. Additionally, this aircraft doesn't have any protective glass in front of the pilot. Without the bulletproof glass, the pilot is extremely vulnerable when going into a head-on fight or when tailing a bomber trying to get a shot. Not only is the pilot put at risk when doing this, but also both the oil and liquid cooling system have a large chance of being destroyed since it does not have any protection.

Survivability and armour

With this aircraft, you will need to strike hard and strike fast. You'll have to since the Pyörremyrsky only has one spar supporting each wing making it easy to rip them off or be blown off by cannon fire. Additionally, this aircraft doesn't have any protective glass in front of the pilot. Without the bulletproof glass, the pilot is extremely vulnerable when going into a head-on fight or when tailing a bomber trying to get a shot. Not only is the pilot put at risk when doing this, but also both the oil and liquid cooling system have a large chance of being destroyed since it does not have any protection.

Pros and cons

Pros:

  • Very good climb rate, can outclimb even the Bf 109 G-2 to common combat altitude
  • Very effective armament, devastating German MG 151/20 and two 12.7 mm LKk/42
  • The two LKk/42s are very effective in pilot sniping
  • Good turn
  • Decent flaps
  • Barely any overheating

Cons:

  • Not very fast
  • Limited ammunition supply
  • Wings can be shot easily (only one spar per wing)

History

Pyörremyrsky, meaning hurricane, tornado or whirlwind in Finnish (pyörre > vortex/whirl, myrsky > storm), was the name of a Finnish fighter design at the end of WWII. Designed by Torsti Rafael Verkkola (1909-1977), the chief designer of Valtion lentokonetehdas (VL or 'State Aircraft Factory') and the designer of the previous Myrsky fighter and the Pyry trainer, the Pyörremyrsky was conceived as a domestic equivalent to the Messerschmitt Bf 109G.

Design

Conceptually, the Pyörremyrsky was very similar to the Bf 109G: it was powered by the same Daimler Benz DB605 engine and had a similar armament, consisting of one hub-mounted 20 mm MG 151/20 cannon and two 12,7 mm hood-mounted machine guns. However, the design was optimized for domestic production, making maximum use of wooden sub-assemblies, and crucially, unlike the Bf 109, it used a wing-mounted landing gear with a wide ground track, giving the design better handling on the ground.

Testing

Design and construction of the Pyörremyrsky met significant delays, and while the original tender called for a prototype to be ready in May of 1944, it wasn't until November 21st 1945 that the prototype was ready and made its first flight.

The prototype was designated PM-1. PM being its intended type designation and 1 being its airframe number. The designation PM is an abbreviation of Pyörremyrsky.

Flight trials of the Pyörremyrsky revealed some minor issues, but other than that, the design was very promising. Performance of the Pyörremyrsky was very similar to that of the Bf 109G, but it had a superior climbing speed and proved to be very agile. One major worry, however, was the quality of the glue used to bind the wooden components.

Fate

The end of the War saw Finland's military subjected to severe restrictions under the Moscow Armistice, which also called for a reduction of its forces. This limited the air force to only 60 fighter aircraft. As a result, the Pyörremyrsky became surplus before it even reached production as Finland chose to retain the Messerschmitt Bf 109G as its primary fighter for economical reasons. The last of the Finnish Bf 109 G's bowed out of service on March 13th 1954. The sole completed prototype of the Pyörremyrsky was put into storage after its last flight on July 22nd 1947, and stricken from the Finnish Air Force's inventory on April 1st 1953. Fortunately the prototype was preserved: it is now displayed at the Aviation Museum of Central Finland in Tikkakoski.

Legacy

Fortunately the Pyörremyrsky legacy continued even after the prototype was grounded. In 1948, construction started on a replacement of the VL Pyry trainer. The new design reused the wing design of the Pyörremyrsky in combination with a new fuselage. This aircraft, which was constructed by the successor of VL, Valmet, was named Vihuri (Gale) and first flew on February 6th 1951. The Vihuri prototype was designated VH-1, VH being an abbreviation of Vihuri.

After successful tests the Finnish air force ordered 30 aircraft on the 27 of Februari 1951. These were collectively called Vihuri sarja (series) II and carried the numbers VH-2 to VH-31. Series II were entered service in 1953 and this prompted the Finnish air force to order yet another 20 aircraft by autumn 1954. These aircraft were collectively called Vihuri series III and carried the numbers VH-32 to VH-51. All of series III were handed over to the Finnish air force on 15 January 1957.

Unlike the Pyörremyrsky the Vihuri was entirely constructed from metal. As a trainer it was a sound design, however it suffered badly in the engine department. The Vihuri design used old Tampere (Bristol) Mercury engines which had been recuperated from scrapped Bristol Blenheim bombers. These engines were already worn out by the time they were installed on the trainers which lead to a lot of breakdowns. After a string of fatal accidents the design was placed under severe suspicion and in March of 1957 all the Vihuri's were grounded after an accident was caused by structural failure. A subsequent inquest showed this particular accident as well as most of the previous ones were caused by pilots violating the flight safety regulations, taking the aircraft beyond its structural limitations. The Vihuri was returned to service in May of 1957, but following two further fatal accidents in 1959 the type was permanently grounded and stricken from the Finnish Air Force's inventory, with 31 out of 32 surviving airframes being sold for scrap; ironically it was outlasted in service by the Pyry (withdrawing in 1962), the design it was supposed to replace as a trainer. The sole surviving complete Vihuri is now displayed next to the sole surviving Pyörremyrsky at the Tikkakoski air force museum.
