Headquarters and Sanitary Aircraft


U-2ShS (headquarters and sanitary) - (presenter - V.G.Sigaev, elaboration for putting on the conveyor - Zhiklenkov).

The plane was designed and built in 1943. The limousine with the M-11F engine was actually a universal transport plane that met the needs of not only wartime, but also peacetime. As a limousine and an ambulance could transport five people - the pilot and one passenger were placed in the cockpit, three passengers in the rear cockpit. In the ambulance version, two wounded on a stretcher and a paramedic in the cockpit or one wounded on a stretcher, two in seats in the rear cockpit and a paramedic in the cockpit were accommodated in the rear cockpit. Another wounded man could have taken the place of a medical worker. A cargo version of the aircraft was also envisaged - 2 crew members were placed in the front cockpit, and the rear cockpit, by removing the seats, was converted into a cargo compartment, in which, in terms of dimensions, an M-11 engine, barrels of gasoline, compressed gas cylinders, pipes, profiles, etc. In addition, instead of cargo, the compartment could accommodate an aero pollinator. Conversion of the aircraft from a command plane to an ambulance or cargo plane took about 10 minutes.

The prototype aircraft was designed and built within one month. The U-2ShS passed state tests in the fall of 1943. With the M-11F, despite the increased flight weight, the speed at the ground increased to 163 km / h. The aircraft was accepted for serial construction at plant No. 494 in the summer of 1944. Preparation of serial drawings was carried out in the OKB from July 7 to July 14, 1944. The lead aircraft of military series No. 9440101 with an M-11D engine was produced in August 1944 (after death NN Polikarpova) and was called Po-2ShS. The presented aircraft did not pass government tests due to manufacturing defects - for example, a stretcher for the wounded did not fit in the cockpit. The aircraft was delivered to plant # 51, where it was being refined. It was built in a small series.

It should be noted that the failure of the serial Po-2 (AL and VS) state tests was associated, first of all, with manufacturing defects allowed by serial factories. In many ways, these defects were due to the insufficiently high qualifications of the working personnel of serial plants - the most experienced workers were at the enterprises of the NKAP, which produced the main combat aircraft. At the factories where the U-2 was made, for example, there were many teenagers. This does not in the least detract from the labor feat of the rear workers during the war years, but it shows the objective obstacles and difficulties in the production of high-quality aircraft, even such simple ones as the U-2.
