S~ Gentleman!

Many Luftwaffe fans extoll the high altitude capability of the Ta-152H-1 at its astonishing 14,800m. Let us not however forget about the brilliant design of the Mikoyan Design Bureau...the I-222(3a). Here is the story behind it.

Mikoyan_Gurevich I-222

The Mikoyan Design Bureau received a request for a fighter with a service ceiling of 46,000ft (14,000m). The prototype was of mixed construction, and taking into consideration the requirement for high altitude, its wings were made larger than those of contemporary fighters, having a span of 42ft 7in (13m) and an area of 240sq. ft. It had a pressurized cockpit, and for the first time in a Soviet aircraft, a special cooler was provided to cool the air entering the carburetor after the first compression stage by means of the AV-9L26 four bladed propeller. The I-222(3a) was powered by a Mikulin AM-39B-1 with a single TK-300B turbosupercharger working from the port exhaust manifold, and ejector exhaust pipes were fitted to the starboard side. Take off power was 1,860hp (1,387kw)and at 43,300ft (13,200M0 the powerplant developed 1,430hp (1,066kw). The aircraft had 2x20mm ShVAK cannons. The canopy was protected front and rear by armoured glass, and pilots seat had an armoured backrest. The machine differed from earlier models by having the radiator moved forward from below the cockpit to a position under the engine. The new fighter was completed in April 1944 and made its maiden flight on May 7, 1944, being tested by A. Yakimov, a highly skilled test pilot. Its speed at 22,000ft (6,700m) was 423mph (682kmh), and at 41,000ft (12,500m) it was 429mph (691kmh). Its service ceiling was 47,500ft (14,500m), a record for Soviet 2nd World War fighters.

hehe, this Soviet bird could look the Ta-152 in the eye at 14,500m.

there seem to be a lot of interesting but relatively unknown soviet aircraft about .. one I saw an article on was a Yak3 with a large nose cannon similiar to the 9T, some of the late war yak were more or less shoehorned wth jet engines in the early post war era as well

Its performance is inferior to the Ta152H's.

I'm sure Oleg will post here soon to express his thanks for this information.

I hope Oleg or somebody could find a cockpit. /i/smilies/16x16_smiley-indifferent.gif

First pic FPS_Stierlitz posted above is I~220, triggered by 1940 ultra~high altitude Ju~86P spy planes. Requirement laid down in early 1941. 4 ShVAK 600 rounds. 1700hp AM-38F. Honestly, not much better than MiG~3, but *much* better weaponry, and double the cannon of (much later) MiG~3U.

Second pic is I~222, 1900hp AM~39B, not reliable. 2 ShVAK 200 rounds. Performance as listed by thread poster. Poor engine reliability. Earlier I~221 had 1550hp AM~39A.

Third pic above is I~224, most advanced MiG high altitude interceptor. 2000hp (at height) AM~39FB (FB /i/smilies/16x16_smiley-surprised.gif ). 550km/hr sea level, 700km/hr at 13km altitude. 2 ShVAK. 4 paddle blades. No need for any of these aircraft, as Germany didn't provide the high altitude, long range threat. And engine + turbos still unreliable.

Last pic above is I~225, generally, highest performing Soviet fighter of war. 1900hp AM~42FB better engine than AM~39. Made as low altitude fighter, unpressurized cabin, but performed well at high altitudes as well. 560km/hr sea level, 730km/hr at 10km altitude. 2 ShVAK, naturally. First flight March 1945 but war already inside Germany, and future lay with jet.

Data lifted from Bill Gunsten's "Aircraft of the Soviet Union."

I~224 model.......

Late war MiGs popular with RC modellers because of the huge historic high altitude wingspan makes easy RC scaling.

hehe, if you want photos and diagrams of this bird, email me at MOH_FOX@compusmart.ab.ca. I will forward what I have. I looks like a super streamlined Mig-3u with an extra wide wing span.

I don't know if it was in a game with you but I had a yak put verticle and lateral distance between my 190D9 w/ mw50 at 6-9 km. At ~9 km I was almost out of gas so I gave up. I never would have thought a yak was that exceptional.

D9 w/MW-50 is slower than D9 without MW-50, bug in FB.

In a similar vein the RAF had some high altitude
versions of the Spitfire VC with a ceiling of
50,000 ft.

Question: did the Ju86P still use diesel engines?

Seems so Aaron, diesel and 39000 feet ceiling.

Very interesting link, especially I~250 (MiG~13) and for members of the militant radical LOMAC camp, MiG~31 many differnt pages...
