DCS: P-51D Mustang

Home > Products > Planes > DCS: P-51D Mustang

The P-51D Mustang is not only one of the most iconic aircraft ever built, it is also arguably the most effective all-round fighter-bomber of WW2. Armed with six .50 caliber Browning machine guns, the Mustang was also able to carry either two bombs or up to ten unguided rockets.

The Mustang began combat operations with the RAF in April 1942, immediately proving its effectiveness both as a fighter and in ‘Rhubarb’ low-level fighter-bomber attacks against enemy airfields, supply trains and in the close air support role. It was especially dominant in dogfights above 20,000. With its graceful lines, distinctive bubble canopy and clipped wings, the ‘D’ variant rapidly became the mainstay of the United States 8th Air Force in Europe.

Powered by the Packard V-1650-7, a license-built version of the two-speed, two-stage supercharged Rolls-Royce Merlin 66, the Mustang had a maximum speed of 390 miles per hour and a combat range of roughly 750 miles (1,200 km). The use of external drop tanks increased the P-51D’s operational range to 1,375 miles (2,200 km), enabling it to escort Allied bombers on long-range missions to the heart of Germany. The P-51D played a major role in establishing Allied air superiority during the June, 1944 D-Day invasion of Normandy, and in maintaining air supremacy as Allied forces fought their way towards Berlin.

Mustang pilots chalked up almost 5,000 victories over enemy aircraft in WW2. The DCS: P-51D is a superb module. Fly it and see for yourself.

The North American Aviation P-51D fighter aircraft is a single-seat, low wing monoplane powered by a 12 cylinder V-1650-7 liquid cooled, Packard built Rolls Royce "Merlin" engine. The engine is equipped with a two-speed, two-stage supercharger and an automatic manifold pressure regulator. The engine spins a four blade Hamilton Standard Hydromatic constant speed propeller.

The Packard engine delivers approximately 1,490 horse power at sea level. The maximum altitude is approximately 40,000 feet. The supercharger ratios are approximately 6 to 1 in low blower mode and 8 to 1 in high blower mode.

The fuselage is a semi-monocoque, all-metal structure. The all-metal wings are built in two halves which are joined at the aircraft center line and are of full cantilever structure. The airfoil is of laminar-flow design, which provides low drag even at high speed. The tail section is metal with fabric-covered elevator and rudder control surfaces. The aircraft is flush-riveted throughout – another factor contributing to its great speed.

Two fuel tanks with a total capacity of 184 U.S. gallons are located inside the wing and an additional 85 gallon fuselage fuel tank is located aft of the cockpit.

The armament consists of six .50 caliber machine guns mounted in the wings. Streamlined bomb racks installed beneath each wing panel can accommodate one 100, 300, or 500-lb. bomb each, or a depth charge or chemical tank. The bomb racks can be easily removed. Bombs may be substituted by droppable combat fuel tanks with a capacity of 75 or 110 U.S. gallons each for long-range operations. The wing can also support up to 10 unguided rockets, or up to 6 if bombs are also loaded.


The DCS: P-51D cockpit is a 100% six-degrees of freedom (6 DOF) cockpit that allows complete freedom of movement around the cockpit. Each panel is reproduced in exacting detail to match 1940s era P-51Ds. This includes all panels, switches, dials, buttons being animated, rendered in the 3D, and with high-resolution textures. Both day and night lighting is available.

When the mouse is hovered over a cockpit control, a tool tip is displayed to indicate the controls function.

P-51D Model

The P-51D model is a very precise and accurate of the Mustang that includes:

  • Full damage model. This includes flight surfaces that can be torn off, bullet holes and structural damage.
  • Multiple-texture maps, normal and specular maps, and 100,000 polygon construction.
  • Full animated surfaces such as flaps, canopy, landing gear, stabilizers, ailerons, etc.
  • Several authentic paint schemes.

Flight Dynamics

  • The flight dynamics of the P-51D are a further develops the Advanced Flight Model (AFM) principles started with the Su-25 and then later improved for Ka-50 and A-10C.
  • A multi-segmented wing provides natural damping; and each aerodynamic surface has a number of airspeed-sensitive points for accurate slipstream effect calculation. Slipstream location and direction depends on plane speed, angle of attack, angle of sideslip, prop thrust and wing lift. All prop side effects, such as slipstream, torque, P-factor are taken in account in overall flight model.
  • A true thermodynamic engine model for all engine modes from idling to maximal power is provided. The boost regulator model was created as an automatic device controlling the throttle. The Bendix-Stromberg carburetor was developed as a true simulation of real device, making it possible to achieve real malfunctions as well as the boost regulator.
  • The second (“slow”) model is used for engine start-up and stop. The true thermodynamic model is used for each stroke of each cylinder, providing individual firing in cylinders, natural plane rocking during the start, over-priming, in-flight prop stop, etc.

P-51D Systems

Open big picture


The power plant of the P-51D is a liquid-cooled, 12-cylinder Rolls-Royce Merlin V-1650-7, built in the U.S. by the Packard Motor Car Company. It is equipped with an injection-type carburetor, a two-speed, two-stage supercharger, and develops over 1400 hp on takeoff.



The supercharger installed on the Packard Merlin engine includes two compressor stages that deliver air from the carburetor intake to the pistons under much greater pressure than would be possible through direct aspiration, allowing a greater fuel-air mixture to be burned and increasing power output.


The carburetor provides automatic control of the fuel-air mixture passed from the air intake to the supercharger and onto the engine manifold for combustion in the cylinders.

War Emergency Power

In order to provide an extra boost to the engine in extreme situations, the throttle can be moved past the gate stop by the quadrant to break the safety wire. The engine will then be opened up to its absolute limit and will give approximately 6 in. of additional manifold pressure in excess of the normal full throttle setting of 61 in. (with mixture control set to RUN or AUTO RICH and prop set for 3000 RPM.) This throttle reserve is called War Emergency Power (WEP) and should be used only in extreme situations. If used for more than 5 minutes at a time, vital parts of the engine may be damaged.
