Kay, I just have to bring a bit focus to the IAR80/81 series of fighters. That little gem of a fighter is avaiable on some 42 maps and I made myself a habit of flying it in the Spitsvs109mods server.

It's a highly underrated plane, easily the FW190 of 1941, especially the 81c version with it's dual MG151/20 (even though it appears it only has AP belting).

Energy retention and maneuverability are exceptional for this time eperiod, especially when flying against russian crates!

Given my obvious enthusiasm for this aircraft, here some facts!

http://upload.wikimedia.org/wikipedia/commons/thumb/a/a5/IAR80.jpg/300px-IAR80.jpg

The I.A.R. 80 was Romania's best indigenously produced fighter of World War Two. First test flown in late 1938 or early 1939 by pilot Dimitru "Pufi" Popescu, it entered service in 1942 and remained in front-line use until 1944.

The manufacturer was Industria Aeronautica Romana {I.A.R.}, based in Brasov in central Romania. Formed in 1925 under state control, the firm drew upon the experience of licence-building many aircraft and engines including the Potez 25, Moraine-Saulnier 35, Fleet 10-G, and a pair of Polish PZL fighters, the PZL P.11 and P.24. The I.A.R. 80 shared the PZL P.24e's tail, rear fuselage and engine design, the rest was all-new. Work began on the I.A.R. 80 in late 1937, the open cockpit prototype was fitted with the 940 hp. I.A.R. K14-III C36 engine which was similar to the Gnome-Rhone 14K Mistral Major. After the initial flight trials the more powerful I.A.R. K14-1000a powerplant was installed and the wing span, area and length were slightly increased.

The I.A.R. 80's flying characteristics were reported to be excellent, highly maneuverable with heavy firepower. A pressurized cockpit was provided and there were several variants, the I.A.R. 81 was a dive-bomber and long-range fighter. Production ceased in January 1943. The I.A.R. factory in Brasov was heavily damaged by Allied bombers in April-May 1944. In 1950 the Aircraft Repairing Shops {ARMV} in Bucharest remanufactured a number of I.A.R. 80's into a two-seat trainer version, the I.A.R. 80 D.C., in the Pipera Industrial Complex. The trainer retained the original's excellent aerodynamic qualities.

The fighter was deployed on home defence in the Bucharest and Ploesti areas as well as in the attack role on the Eastern front during 1942-3. It was sometimes mistaken by Allied pilots for the Focke-Wulf Fw-190.

A number of I.A.R. 80's were scrambled against the well-publicized USAAF mission to bomb the oil refineries at Ploesti, Romania on 1 August 1943. The B-24s of Ninth Bomber Command took very heavy losses from flak, fighters {Bf-109s and I.A.R. 80s} and navigational errors. The Ploesti raids of July 9 and 15, 1944 were met by about 25 I.A.R.80 sorties.

After World War Tzwo, the Russians shipped home the entire I.A.R. factory and all aircraft from Brasov, as "war reparations". There was even a joke around, at that time: Do you know the Principle of Lavoisiev? Nothing is lost, everything is transported.

I agree. The IAR81c is a great plane to fly. Not much for looks, but she's got it where it counts. Good maneuverability, great firepower. What's not to like?

Let me add that the semi-monocoque "rear fuselage" included cocpit area. Ahead of it in P.24 there was aluminium framework with fuel tank, wings and struts attachment points and some installations. Romanian designers inserted there their own framework section, steel one this time, with wings, tanks and so on.
And sidenote to sidenote: PZL.50 airframe was actually made along the same lines, just that P.11c parts were used and there semi-monocoque section started behind cocpit.

P.24 and IAR-80 shared the engine, but I belive that engine mounting and cowling were Romanian-designed.

interesting, the similiarities are quite obvious, thanks for the info! Eastern european aviation before and during the war is still mostly white pages, though I am pretty sure there were more interesting designs around. Will have to dig into this topic a bit more.

Yeah it's a pretty decent plane in Il-2.

It was pretty good for 1940/41 but from what I have read, due to technical problems it didn't enter service until 1942. Seems like it would have been obsolete then since it couldn't get over 500 kph but I don't really know or remember how effective it was in service.

Personally, I'd say the IAR 80/81 was far from the ugliest aircraft of its type and period, and from some angles looks quite pretty, though if you were flying a B-17 when you saw it you might feel differently...

I flew it in an offline campaign, and it seemed to hold up well against the early Yaks etc, though it would have been well outclassed later in service.

My only real gripe on the plane was that without resorting to 'Wonder Woman' view, landing actually on the runways seemed to require psychic powers, as the forward view at high angles of attack is basically zero. http://forums.ubi.com/groupee_common/emoticons/icon_frown.gif Does anyone have comments on landing techniques, beyond the obvious steep curved approach one would use for say a Spit or a MiG-3?

Actually part of the "wrong looks" comes from the bad modeling. Most likely they inacurate/wrong blueprints.
the most visible flaw is in the rear part of the fuselage. in the game that section looks almost round, while the real thing was a lot more narow on the top:

Haven't flown it much, but I always hated seeing it on my Soviet campaigns. The DM seems just this side of ridiculous, much like the early I-153s in the original and Forgotten Battles phases of this game engine. Combined with the maneuverability and firepower, it makes a daunting opponent.

As for the rear fuselage, that's a pretty subtle shape to model on what was originally thought a relatively obscure non-flyable. Given the fact that without 6DOF, you can't look over your shoulder worth a damn anyway, it is probably a purely esthetic issue.

I've never had trouble landing it. It's a bit tricky because of the lack of a tail wheel but if you can land an I-16 you can land the IAR. Just use the rudder to keep from veering off the runway I guess.

And the AI for the IAR is tough, I made a mission in my first Air Pirates campaign where you fly in a 1941 LaGG-3 against a few IAR's. The LaGG has a higher top speed but doesn't keep its speed well so the IAR's just zoom up and away over and over and keep making dives on you.
