MiG-19 FARMER - Design

MiG-19 - the world's first serial production supersonic fighter - was made with the normal aerodynamic configuration with a mid-wing and swept high aspect ratio. The fuselage is round, and oval in the rear section.

The semi-monocoque fuselage of circular cross section, passing in the tail section into an elliptical. The fuselage is long, tube-shaped, and tapers slightly to the blunt nose and widens to the exhausts. The fuselage is made mainly of aluminum alloys, using structural steel. The forward fuselage includes avionics bays. At the bottom of the forward fuselage of the MiG-19 / 19C mounted the Pitot static tube.

The aft fuselage is attached to the nose on four bolts, it is detachable for access to the engines.

The MiG-19 was the first Soviet fighter equipped with a brake parachute. The drogue parachute container is placed at the bottom of the rear fuselage. To reduce speed there are 2 airbrake areas of 1.04 m 3 on the sides of the fuselage, a guard area of 0.45 m 3 under the fuselage, and (for the first time in domestic aircraft construction) brake parachute PT-19.

There is a bubble canopy well forward on the nose. In the nose is a sealed cockpit with ejection seat. The cabin is closed transparent teardrop canopy. Flat frontal glazing includes a motionless visor made of bulletproof glass. The mobile segment slides back. In the case of depressurization at high altitude it has been specially designed pressure suit WCC-2 (still used).

The aircraft's wings are mid-mounted, swept-back, and tapered with blunt tips. The wings use the profiles TsAGI P-12C and TsAGI SR-7C. Mechanization of the wing consisted of ailerons and flaps, TsAGI flap-type. The all-moving horizontal tail is based on TsAGI-M profiles. There are wing fences and wide wing roots. The wing is single-spar with internal braces, sweep angle through fourths of the chords of 55 degrees. The wing has a negative transverse On the upper surface of each wing is set one aerodynamic ridge. Mechanization of the wing is made up of the ailerons and flaps. The MiG-19C, and all later moadels mounted mechanically connected spoilers with electronical on the lower surface of the wing.

The tail fin is sharply swept-back and tapered with blunt tips. Flats were high-mounted on the fuselage and swept-back with blunt tips. The tail assembly is composed of a keel, rudder and stabilizer with elevators. From the MiG-19C, instead of the stabilizer with elevators installed all-moving stabilizer. The angle of sweep of the keel and the leading edge of the stabilizer 55 degrees. Under the fuselage to increase directional stability is mounted an aerodynamic ridge area of 0.54 m3.

The tricycle landing gear is retractable, with a nose strut. The nose wheel retracted by rotating forward in a niche of the fuselage. Main struts abut the recess of the wing in the direction of rotation of the fuselage.

The propulsion system consisted of two turbojet engines and a single, round air intake in the nose. There are two AM-9B (RD-9B) engines mounted side by side inside the body with afterburner mounted in the rear fuselage. Note that what appears to be a single air intake is actually separated on the inside with each engine drawing air from its own intake. The front air intake, common to both engines, is divided by a vertical partition into two channels for supplying air to the engine. Two other aircraft that have a single air intake with two engines are the Lightning and the G.91Y. There are dual exhausts.

Fuel is housed in 4 tanks placed in the rear fuselage. The total capacity of the four fuselage fuel tanks of 2170 liters. The possibility of suspension under the wing of the two discharged tanks with a capacity of 760 liters or 400 liters. Most of the flights of the MiG-19 were performed with external fuel tanks.

The flight control system for its time was nearly perfect. The control channels for roll and pitch were set with irreversible hydraulic actuators. Pitch controls were duplicated electromechanical system. The channel enabled pitch control with the device 2A-AGC control, preserving the natural load for the pilot on the control stick, regardless of the speed of flight. The control of the aircraft pitch deviation was made elevators and all-moving stabilizer, the rate - rudder deflection, roll - deflection of the ailerons and spoilers. Controls were traditional pedals, throttles.

The instrumentation ensured flying by day and night, and execution of complex maneuvers in adverse weather conditions. The fighter has an optical sight ASP-5 nm. Interceptors were equipped with "Emerald" radar combined with a telescopic sight.

Armament consisted of three guns, 30-gauge 30 mm (in the first MiG-19 there were three cannons NR-23 were 23 mm). The HP-30 is easy to distinguish from the HP-23 by the presence of the muzzle brake. One gun was mounted in the bottom right of the nose, the other two in the roots of wing panels. In the MiG-19P fuselage gun was not installed. Ammunition was 120 rounds for each barrel. The four underwing hardpoints provided for the possibility of suspension units and different caliber bombs up to 250 kg. The MiG-19P was armed with four UR "air-air" K-5M with radio command guidance system, and the guns were not installed.

Despite its age, the MiG-19 and its descendants exhibit good handling characteristics at low altitude and a surprisingly high rate of climb, and their heavy cannon armament a one-second burst from 3x 30 mm NR-30 cannons had a projectile mass of 40 lb (18 kg) makes them formidable adversaries in close combat.
