DCS: MiG-15bis

Home > Products > Planes > DCS: MiG-15bis

Developed in the years immediately following World War II, the MiG-15bis was a first-generation jet fighter designed by the Mikoyan-Gurevich design bureau of the Soviet Union. The MiG-15bis is a single engine, swept-wing jet that saw over 15,000 copies produced. The MiG-15 gained fame in the skies over Korea where it battled the F-86 Sabre and other allied aircraft. It proved an excellent match to the Sabre, and it often came down to the skill of the pilot that determined who made it home and who was left dangling from a parachute. Having an excellent thrust-to-weight ratio and good climbing characteristics, the MiG-15bis was also armed with two NR-23 23mm cannons and a single, powerful N-37 37mm cannon. Not surprisingly, it is considered by many as one of the deadliest fighters of the era.

Armament

The primary mission of the MiG-15bis is destruction of airborne targets, including hostile fighter aircraft. However it can be used for limited ground attack operations using onboard cannon systems or two 100 kg bombs.

The armament system includes cannon systems, bombing system, ASP-3N automatic gunsight, S-13 gun camera, cockpit armoring, and signal flares.

VK-1 turbojet engine

Unlike the original MiG-15, the MiG-15bis model is powered by the Soviet-produced VK-1 engine in place of the Rolls-Royce Nene I (II). The engine produces 2700 kg (5950 lbs) of static thrust.

  2. Centrifugal compressor
  3. 9 can combustion chambers
  4. Compressor turbine
  5. Engine oil system components
  6. Compressed air supplied to the combustion chambers
  7. Jet pipe and exhaust nozzle (not shown)

The VK-1 engine model in DCS: MiG-15bis is created as a gas flow chamber, the dynamic specifications for which are determined in real time by a complex system of supporting individual models of primary powerplant elements like the air intake, centrifugal compressor, combustion chambers, compressor turbine, exhaust. The model also includes the fuel supply system and its operational characteristics. Together, these individual model elements combine to provide the following important engine operation specifics:

  • Successful engine start depends on correct start-up procedures to ensure that normal operational parameters are met. Failing to do so may result in abnormal conditions such as a "hot start" and force a start abort.
  • Idle power RPM depend on flight conditions: altitude, mach number, as well as atmospheric conditions such as temperature and pressure.
  • Short-term engine overspeeding and overheating is possible with aggressive throttle control.
  • Engine responsiveness varies depending on RPM.
  • The engine exhaust temperature is based on a complex relationship of engine power setting, flight and atmospheric conditions.
  • Specific fuel consumption is based on a non-linear relationship with engine power setting and flight conditions.
  • Engine performance dynamics (RPM and gas temperatures) are modeled in real time and produce accurate results during engine start, in flight, and during engine shut down.
  • Windmilling of the engine is modeled and allows for an air start of a failed engine, depending on engine RPM.
  • Unstable operation of the engine is modeled, such as engine surge, flameout, etc.
  • Engine operation in zero and negative G is limited by the fuel supply system.

Engine fuel control system

The engine fuel control system provides atomized fuel to the combustion chambers as required to ensure normal engine operation. Fuel flow is provided by fuel pumps according to throttle position set by the pilot in the cockpit, while actual fuel supply to the engine is metered main fuel regulator.

The fuel system consists of two main tanks with a total capacity of 1410 L. The forward tank has a capacity of 1250 L; the rear tank 160 L. The rear tank is constructed of two separate, interconnected containers of 80 L each. The fuel quantity is displayed by the fuel quantity gauge (6) installed on the forward tank, however the gauge only displays up to 1050 L.

A fuel warning light illuminates in the cockpit when remaining fuel quantity reaches 300 L.

Two drop tanks with a capacity of 300, 400, or 600 L can be carried on the wings.
