Yeah I am aware that the standard 12Y is not an inverted V engine. I don't remember the exact reasoning behind selecting the inverted-V over the standard but it might have had something to do with the cannon fit if I remember right. Direct injection should also allow for operations free from power loss in higher-G environments which the early Merlins apparently had issues with due to their natural aspiration. I'm not knowledgeable in engines terribly well so correct me if I'm wrong.

Also an inverted "V" has also the gravity centre lower than an normal "V". Try to fit the DB600/601 engine if your timeline allows.

Hmm, possibly. Just not sure how such an engine could come to Sieranian hands. After 1936 relations with Germany are supposed to have weakened due to ideology differences but it may be possible to indirectly get those engines, not certain.

Very nice work.
One nit-pick I'd have is that the counterweight of the rudder (that part that's in front of the axis) seems too huge to me relative to area of rudder and whole vertical stabilizer.

Thanks for the feedback.
Looking at that image it does indeed look like the tail surface is fairly large when compared to the rudder. Maybe it can be said that it was the result of attempting to improve longitudinal stability in the aircraft given it's comparatively short fuselage (when compared to some other types) xD

I was sorting through my dropbox folder earlier and found this drawing that I've never posted. As I couldn't see anything significantly wrong with it, I decided I should maybe post it here as it is a key part of the SRNs early formation;



The Protected Cruiser Zhemchug was laid down at the Nevsky Shipyards in Petrograd, Russia on 1 June 1902 and was launched on 14 August 1903, in the presence of Tsar Nicholas II. Construction was plagued by delays, including flooding in November, and an ice storm in December. However, with the start of the Russo-Japanese War in early 1904, construction efforts were greatly accelerated. Zhemchug was formally commissioned on 29 August 1904 and was assigned to the Second Pacific Squadron of the Russian Pacific Fleet. On 27 September 1904, she participated in a naval review off Reval attended by Tsar Nicholas II, and departed for the Far East the following day.

Under the overall command of Admiral Zinovy Rozhestvensky, Zhemchug was part of the Second Pacific Squadron intended to relieve the Japanese siege of Port Arthur. However, she separated from the main squadron at Tangiers and transited the Suez Canal, and rejoined the main fleet at Madagascar. During the transit of the Indian Ocean, she acted as a scout for the main fleet and was frequently on detached duty. Conditions during the voyage were appalling, with the ship overloaded with coal for the voyage, even in the crew compartments, and the crewmen suffering from the unaccustomed tropical heat, poor food and poor hygiene and frequently mechanical failures. One crewman ran amok off Madagascar and had to be shot.

The Second Pacific Squadron took part in the decisive Battle of Tsushima from 27–28 May 1905 and, as part of Admiral Oskar Enkvist's cruiser division, Zhemchug was one of the first ships to open fire on the Japanese Combined Fleet. She took severe damage in the battle, taking 17 hits, with 2 officers and 10 crewmen killed and 32 crewmen seriously wounded. However, she managed to escape sinking or capture after the Russian defeat, forming up with the surviving cruisers Almaz and Oleg as well as the destroyers Bodry, Grosny and Bravywhere. On the morning of the 29th the burning but still afloat Admiral Ushakov was sighted and the ragtag collection of battered warships worked their way North as fast as their engines would carry them.

Originally the plan had been to return to Port Arthur or Vladivostok however poor weather and concern over the bases' longevity saw the ships instead sail to the small port of Anadyr where refuge was taken in the sheltered harbour. These four ships would still be in Anadyr for repairs by the time of the revolution on 17 October 1905 which saw the Tsar formerly declare the independence of the Far Eastern Provinces as part of the forced changes. All seven ships were thus seized by the new Sieranian Government and became the foundation of its Navy. The crew of the ships themselves mutinied against their offices during the revolution which resulted in a number of arrests and court martials until the revolution was resolved.

The Zhemchug herself was repaired by January 1906 and entered service as the first and at the time only ship of the new Navy capable of operation in open sea. Advances in Naval Technology however would see the ship become obsolete and in 1911 she was laid up in reserve. The First World War would see her reactivated as a patrol ship where she provided screen defense for merchant vessels and embarked on a number of unsuccessful attempts to track down the German Raiders.
After the war she served as the state yacht for a time, stripped of most of her armament and with rebuilt upperworks. Once the replacement was available however, the ships future was once more cast into doubt.

By the end of the 1920s there was talk that the ship was to be scrapped. By this time she, along with the Admiral Ushakov were the only surviving vessels from the foundation of the Navy. As the later ship was being used as an Ammunition Hulk, former crew and their families petitioned the Government and the Navy to preserve the Zhemchug as a symbol of their achievement during the revolution. Eventually the protests were successful and the Zhemchug was returned to Anadyr for a complete rebuild which saw her returned to the condition she had been on that day.

Today the Zhemchug is the only pre-WW2 ship to be preserved as museum and the only warship to be thus preserved.

Nice work.

Very nice ship and excellent drawing.

Thanks all.

Here is the final production version of the Kanyuk, the PI-34C;



Developed after feedback from the aircrafts combat experience in Northern China, the PI-34C was overall a better aircraft that came far too late to be truly effective. As part of the major changes, the aircraft received a more highly tuned version of the Movich engine, taking engine power up from 850hp to 980hp at altitude. This engine was also optimised for mid to low-altitude performance unlike its predecessor. The composite airframe was replaced by a wholly metal airframe and the armament was improved with the replacement of the 7.62mm machine guns with the larger 12.7mm. The 20mm cannon stayed the same but had an improved mechanism allowing for quicker firing.
Visually, the primary change was the cut down of the turtle decking behind the cockpit to improve rearward visibility. Finally the control balancing was adjusted to ease the effort required on behalf of the pilot to operate the elevators at high speed.

Testing began in the end of 1941 just weeks before Japans declaration of war on the United States. The threat of the war spreading saw the testing rushed and, despite the loss of the first prototype due to an engine failure, the aircraft was put into high priority production alongside the Skopa. By 1942 the aircraft was already showing the age of its design, proving that even with its improved performance it was still outclassed by the superior Japanese aircraft. Engine reliability issues plagued the aircraft throughout its operational service and production was wound down as more advanced types became available. Despite this, the Kanyuk found a new role as a training aircraft, being considered to be a decent airframe for new pilots funneled into the fighter wing to master the techniques of flying solo in a modern fighter. It was in this role that the C variant made a name for itself, it's pilot friendly characteristics (other than the engine) ensuring its survival well beyond the types combat lifetime.
