Construction

Supersonic fighter-bomber plane with variable wing geometry.

Construction Su-22 M 4

One-seater, single-engine fighter-bomber plane. Built in a classic layout with a variable geometry wing. The fuselage is made of aluminum and titanium alloys.

The wings consist of a fixed part and external moving parts, 4 m long, taking two positions. The minimum skew angle is 30 degrees. The maximum 63 degrees. It is also the angle of skew of the fixed part of the wings. One and the other part are hinged together. At the front with a large bearing pin, which is the axis of rotation. On the back of the support is a four-wheeled trolley moving on guides mounted inside the stationary part. The movement is carried out by a hydraulic system. Fixed parts were equipped with two sections of slotted flaps on the canoe. The outer parts received ailerons and slit flaps on the path. On the leading edge there are three-sectional gills (slots). The wing received two pairs of high aerodynamic blades and three pairs of smaller aerodynamic blades that strengthen the construction of fixed wing parts. Covering of the wings was made by chemical etching. Steering surfaces were made of 3-ply glued boards with a honeycomb filler.

A fuselage with a half-shell structure and a section similar to a circular one. The maximum diameter is 1.75 m and the length of the hull is 15.572 m. The frame fuselage to No. 13 is tilted down by 3 feet. It is technologically divided into two parts. The division takes place at the number 34 frame. The removable rear part of the fuselage allows access to the engine. Front air grip with central intake cone that can take two positions. The cabin is hermetic and air-conditioned. It provides excellent working conditions and good visibility. The cabin was placed between frame number 4 and 9. Throw-out seat K-36 class 0-0. It allows you to safely leave the aircraft in the speed range from 0 km / h to 1 300 km / h, at any altitude. The cover opens upwards to the rear. A periscope was placed on the windshield to observe the rear half-zone. Four aerodynamic brakes are located in the rear of the fuselage.

The tail. Horizontal plate with 55 degrees angle on 25% chord. Mounted with a negative 3-degree lift. At the ends, anti-flutter masses were mounted. The shift is from +25 degrees 30 minutes to -10 degrees. The vertical elevation is divided into a rudder and a ballast. The skew is 55 degrees.

The aircraft has a three-points chassis with oil-pneumatic shock absorbers and hydraulic brakes. The front wheel, 660 x 200 mm, is pulled forward into the chamber under the cab floor. Main chassis with single wheels, size 880 x 230 mm. The base of the chassis is 5.24 m, the main chassis spacing is 3.85 m.

Construction Su-22 UM 3 K

Differences between one-seater and two-seater aircraft.

The plane has a double cabin. Aviators' seats were placed in tandem. A centralized catapulting system with K-36 DS 2 armchairs was introduced. The instructor's cabin was equipped with a periscope system similar to that used in Su-7 U aircraft. The place for the second seat was obtained at the expense of reducing the fuel tank No. 1. In general, the fuel supply decreased to 3 050 kg, and thus range.

Aircraft equipment modified by introducing the SAU-22 MU control system. An SPU-9 on-board telephone and MS-61 tape recorder have been added. The left cannon was dismantled, but the weight of the aircraft increased to 10,900 kg anyway. The lifting capacity of the weaponry decreased to 3,000 kg and therefore the second pair of sub-fuselage nodes have been abandoned.

Su-22 drive

Su-22 airplanes, depending on the customer, are equipped with an AL.-21 or R-29 engine. All Polish Su-22 planes were equipped with AL-21 engines, the same ones that were powered by Su-20 planes. These engines are being renovated in Poland in Warsaw.

AL.-21 is the engine of A. Lulka AL.-21 F-3 of 1 x 76.50 kN, and with the afterburning 1 x 110.00 kN. This engine is special adapted for flights at low altitudes. It is a single-flow turbine composed of; 14-stage axial compressor, annular combustion chamber, 2-stage turbine and afterburner. The engine is cooled by air drawn by 4 grips placed on the fuselage at the rear.

Kerosene fuel T-1, TS-1, RT. IPM-10 or synthetic WNII-50 oil. Unit fuel consumption 0.9 - 1.2 kg / daN / h, with afterburning 1.5 - 2.0 kg / daN / h. The engine's resure is 900 - 1500 hours depending on the production series. The period between repairs is 350 - 450 hours.


The fuel system consists of 4 tanks placed in the fuselage and two integral ones placed in the movable parts of the wings. In addition, the aircraft can carry 4 additional tanks (2 under the fuselage and 2 under the wings).
