And after 50 hours of continuos work, there she is!


History:

The Sukhoi Su-25 Grach (Russian word for rook; NATO reporting name: Frogfoot) is a single-seat, twin-engine jet aircraft developed in the Soviet Union by Sukhoi. It was designed to provide close air support for the Soviet Ground Forces.
The first prototype made its maiden flight on 22 February 1975.
In September 2015, it was reported that at least a dozen Su-25 were deployed by Russia to an airfield near Latakia, Syria, to support the Russian forces there who were taking part in the Syrian offensive against ISIL.

Design:

The Su-25 has a conventional aerodynamic layout with a shoulder-mounted trapezoidal wing and a traditional tailplane and rudder. All versions of the Su-25 have a metal cantilever wing, of moderate sweep, high aspect ratio and equipped with high-lift devices. The wing consists of two cantilever sections attached to a central torsion box, forming a single unit with the fuselage. The air brakes are housed in fairings at the tip of each wing. Each wing has five hardpoints for weapons carriage, with the attachment points mounted on load-bearing ribs and spars. Each wing also features a five-section leading edge slat (-15°) when fully deployed, a two-section flap (-35°) and an aileron (+20°/-20°).

Specifications:

  • Crew: 1
  • Length: 15.53 m (50 ft 11 in) (including nose probe)
  • Wingspan: 14.36 m (47 ft 1 in)
  • Height: 4.8 m (15 ft 9 in)
  • Wing area: 33.7 m2 (363 sq ft)
  • Empty weight: 9,800 kg (21,605 lb)
  • Gross weight: 14,440 kg (31,835 lb)
  • Max takeoff weight: 19,300 kg (42,549 lb)
  • Powerplant: 2 × Soyuz/Tumansky R-195 turbojet engine, 44.18 kN (9,930 lbf) thrust each

Performance:

  • Maximum speed: 975 km/h (606 mph, 526 kn)
  • Maximum speed: Mach 0.79
  • Range: 1,000 km (620 mi, 540 nmi)
  • Combat range: 750 km (470 mi, 400 nmi) at sea level with 4,400 kg (9,700 lb) of ordnance and two external fuel tanks
  • Service ceiling: 7,000 m (23,000 ft)
  • g limits: +6.5
  • Rate of climb: 58 m/s (11,400 ft/min)

Features:

  • Semi-realistic HUD with working artificial horizon
  • Realistic performance and flight characteristics
  • High accuracy and level of detail
  • Landing Lights will automatically deploy when Landing Gear is lowered. To retract them simply turn off all lights
  • Realistic Suspensions and Landing Gears
    CAUTION: Due to the fact that for realism purposes the whole payload's drag has been set to 1, the plane will tend to have a slight autoroll, because the game physics. I will correct the problem in a newer version.

    @SneakySniper maybe, I wouldn't give it for certain.
    I've missed a lot both the game and the community this whole time, and many dear friends that I haven't heard from since I left.

    @asteroidbook345 as @SneakySniper already said, DCS is quite a nice source. The 3D Aircraft Model that the game uses is incredibly detailed and realistic.
    By being a scale modeler myself, I have lots of both physical and digital references to consult for my works

    I'm not completely sure about the rudder. How did you find out that the upper rudder segment is reversed?

    Hey where did you find the info for the missiles about the targeting angle, maxAngleAdjustmentRate etc? I mod aircraft and im currently modding alot of cold war aircraft. Though having a source that gives this info would help with really any mod. Or is the info just preference and isnt realistic?
