The Sukhoi P-42 test aircraft ( Russian Сухой П-42 ) is a record-breaking version of the Su-27 . With the P-42 a total of 27 climb time records and height records were set.

Name P-42

The FAI reported designation of the aircraft was chosen to camouflage the secret aircraft development in memory of the role of Soviet aircraft in the fighting for Stalingrad. "P" (Russian. "П") denotes " Перелом " (" Великий перелом ", large turning point , transcribed perelom ) and stands for the break-up of Army Group B at the end of 1942.

history

Two aircraft from the pre-series T-10S of the Su-27 were converted into record aircraft:

The T-10-15 P-42 (serial number 05-01) was to be used with the R-32 engine - a more powerful version of the Saturn AL-31 F - for climbing time records. The take-off mass of this aircraft could be reduced by about 2 t to 14,100 kg through measures such as the use of light metal for the nose cone, expansion of essential parts of the avionics , unadjustable air inlets, so that with 2 × 133 kN engine power the thrust-to-weight ratio about 1 .93 was. As a result, the speed of sound could also be achieved in a vertical climb .

Flight records were set by WG Pugachev , NF Sadownikow, OG Zoi and EI Frolow. The climbing time records set in 1975 with the F-15 at 3, 6, 9, 12 and 15 km altitude were exceeded by the P-42. With a total of 27 world records, the P-42 holds second place among the supersonic aircraft (after the MiG-25 with 29 world records , including 3 absolute records).

T-10-20 “№ 20” on the Khodynka field in Moscow

The second record aircraft was the T-10-20 (05-05) with a fuel capacity of 12,900 kg (Su-27: 9,400 kg). The planned range record attempts in the FAI category C1 were not tackled.

Whereabouts

The T-10-15 is located on the Sukhoi site in Zhukovsky near Moscow. The T-10-20 was converted to the pre-production version T-10KTM of the Su-27K with foldable wings and tailplane for a potential aircraft carrier use and after the end of the test it was parked on the Chodynka field in Moscow. In 2012, WW Sadoroschni took the aircraft over to his private museum near Medyn (Kaluga Oblast).
