OKB Mikojana i Guriewicza MiG-19 P, PM
The first supersonic fighter aircraft in Polish aviation, at the same time the first armed with guided missiles.
Construction MiG-19 PM
Single-seater, twin-engine, supersonic fighter aircraft, medium wing, all-metal. Equipped with SR (radar station).
Bevel 55 degrees (to the 1/4 chord line), relative thickness from 8% at the ends to 8.74%, at the hull. Negative rise -4.5 degrees, span of 9 m, area 25.0 m2, elongation 3.24. Half-shell wing construction, typical for MiG aircraft, with main, auxiliary, front and rear girder and 27 ribs. 1.5-2.0 mm thick duralumin sash cover. The transition between the fuselage and wings profiled. 32 cm high aerodynamic comb on the upper surface of each wing. Shuttlecocks with an area of 0.78 m2, with internal aerodynamic compensation. The left aileron has a trimmer. Swivel range 20 degrees, trimmer 15 degrees. In order to increase the effectiveness of transverse control of the aircraft at high speeds, kinematic choppers are attached to the lower surface of the wings, coupled to the ailerons (when the aileron is tilted down, the corresponding chopper on the opposite wing extends). Flaps, as in previous MiGs, with a sliding axis of rotation (approx. 40% of the chord back). Flap area 2 x 1.72 m2, swing 15 degrees takeoff and landing 25 degrees.
Under the wings there are 4 launchers for guided missiles class p-p type RS-2US, which are the distinguishing feature of the PM version.
Half-shell construction, circular section flattening towards the end. Divided into front and rear, disconnected between frames 20 and 20A. In the front, an air inlet separated by a vertical partition, above it an AKS-3M or AKS-5 photo-carabiner, below the base of the PWD-4 type air pressure receiver. Above between the first and fourth frames, a bay with a battery and radio equipment. Front chassis retractable between frames 1 and 5A. Pilot's cabin between frames 4 and 9 (cover reaches frame 13). At the bottom, between the 11th and 14th frame, an aerodynamic brake with an area of 0.45 m2 and an angle of inclination of 45 degrees. Two other aerodynamic brakes (total area 1.04 m2, 25 degree swing) on the sides of the hull between frames 22A. and 26. The engine compartment begins from frame 15. The 21th fuselage aerodynamic comb with cushioned tail bumper begins from frame. A profiled fairing at the end of the hull. In the bottom of the rear of the fuselage there is a bay with a braking parachute TP-19 with a diameter of 4.5 m. Working hull cover, dural, 0.6-1.2 mm thick. Additional internal steel cover near the engines.
Ventilation type semi-hermetic pilot cabin, protected by armor plates (10 mm in the front, 16 mm in the back, 25 mm behind the pilot's head). The head restraint is also used to break the closed cabin cover in case the pilot catapults. Two-part cab cover: fixed part with multilayer windscreen 64 mm thick and movable part, sliding back. A chair thrown out with a face protection curtain, fired with a powder charge with a telescopic mechanism (for safer throwing out the chair at high flight speed). Oxygen device KKO-1. In order to prevent dust, water or snow from entering the cabin during parking, it can be encapsulated from the outside. Hull length 10.428 m, aircraft without Pitot tube 12.54 m, total - 14.64 m.
Bevel of the leading edge 57 degrees 37 minutes (more on the fuselage part), relative thickness 8%. The surface area is 4.17 m2, including 0.93 m2, occupied by a 25 degree tilting rudder. Plate height elevation, with a movable area of 5.5 m2 (7.78 m2 total) and 17 degrees downward tilt angles and 7 degrees 10 minutes upwards (measured in the plane of the air stream). Relative thickness 7%, skew angle 55 degrees, span 4.46 m. The plate tail control system includes a non-returnable amplifier BU-14MS and an ARU-2A automatic device adjusting the load on the joystick to the pilot's habits. Control system powered by a separate hydraulic system, duplicated by the main hydraulic system; additionally, as a second protection - the APS-4 electric mechanism.
The structure is similar to the landing gear of the MiG-15 and MiG-17 aircraft: three-wheeled, swingarm type, oil-air shock absorption, main pulled into the wings, front into the fuselage in the forward direction. Wheel dimensions: 500 x 180 mm, main 660 x 200 mm. Main chassis wheel track 4.156 m, chassis base 4.448 m.
The drive unit is RD-9 B of S. Tumański construction with 2 x 2,550 kG thrust, and with 2 x 3,237 kG afterburning. The engine is built of a 10-stage axial compressor, with a 5-stage anti-pump relief, 10 incandescent pipes, a 2-stage turbine, afterburner, three stages of discharge nozzle adjustment. Four flexible fuel tanks with a total capacity of 2,155 liters. In addition, two suspended fuel tanks with a total capacity of 1,520 liters.
Two RD-9 B turbojet engines with a nine-stage axial compressor and a two-stage turbine. Fuel in the total amount of 2170 dm3 in 4 hull tanks: two soft ones behind the cab (1485 and 330 dm3) and two metal ones under engine nozzles (180 and 175 dm3). In addition, under the wings on BD-3-56 universal locks it is possible to suspend two additional tanks of 760 dm3 or 400 dm3 (from MiG-17). Take-off thrust of the RD-9B engine at the maximum range (11 150 rpm) 2 x 25.5 kN, with afterburning - 2 x 32.4 kN. Turning on the afterburner is accompanied by an increase in specific fuel consumption by approx. 50-60%. This consumption, e.g. at a speed of 1000 km / h and a flight height of 11,000 m, is 0.12 kg / (N / h) in the maximum range and 0.18 kg / (N / h) with the afterburner switched on.
Equipment; RP-5 radar station (in the MiG-19 PM version the RP-5 radar station was replaced with RP-2U (Izmrud-2), adapted to shoot only with K-5 missiles (RS-2US). The aircraft is armed with 4 missiles. ), Radiocompass ARK-5, Automatic shooting sight coupled with rangefinder ASP-5 n-3 W, SSz-45 photocarabine.

Armament MiG-19 P artillery: 2 cannons NR-30 - two in the base of the wings (ammunition arranged in the wings along their front edge - 2 x 73 cartridges).
Armament MiG-19 PM - rocket: 4 APU-4 launchers for the NCR RS-2 US.
In place of additional fuel tanks, two ORO-57K missile launchers carrying 8 57mm S-5 unguided missiles or two bombs up to 250 kg can be mounted.
Changes introduced in the MiG-19 P compared to the MiG-19 S not used in Polish Aviation;
The basic novelty was the use of RP-5 target search and tracking radar, which forced further changes, such as: Limiting artillery equipment to two wing cannons (23 mm), and there were 3 cannons. Third gun placed in the hull.
Lengthening the hull front, shifting the front undercarriage shin. The chassis base increased to 4.448 m and it was 4.398 m.
Moving the air pressure receiver base to the right wing and photocarabine to the right side of the fuselage. The pressure receiver was on the boom in front of the hull.
Change of electrical, pneumatic, oxygen and fuel installations. The instrument panel layout has changed.
The widening of the pilot's cabin changed the movable part of the cover accordingly. Change in the arrangement of radiotechnical equipment.
In the initial series of the MiG-19 P version, the "Gorizont-1" station was used to guide the aircraft to the target from the ground command point, therefore the RSIU-4W radio station was replaced by RSIU-3MG, cooperating with the "Gorizont-1" station.
The use of RP-5 radar caused changes in the structure of the front of the fuselage to frame 12.
To facilitate the aiming of the aircraft at a high altitude, the ARU-2W automatic control adjustment system was introduced, corrected according to the height of up to 15,000 m (ARU-2A - up to 10,000 m). Therefore, the weight compensation of the ailerons was also changed.
Changes made to the MiG-19 PM compared to the MiG-19 P:
The main novelty was the new type of weaponry: RS-2 U or RS-2 US (K-5) missiles with radio guidance system. For this reason, the RP-5 radar station and ASP-5N sight were replaced with the RP-2U radiolocator adapted to K-5 missiles and the cannon was removed from the wings by mounting 4 APU-4 rocket launchers instead. The internal wing construction has changed accordingly. In addition, the emergency dropping mechanism of the cabin cover was changed, the "Syrena-2" warning station was dismantled, the MRP-18P marker was changed to MRP-56, etc.
