SA-342 Gazelle “Viviane” for DCS World

  1. Home / SA-342 Gazelle “Viviane” for DCS World

The Gazelle is a five-seat helicopter, commonly used for light transport, scouting and light attack duties. It is powered by a single turbine engine and was the first helicopter to feature a fenestron tail instead of a conventional tail rotor. It was designed by Sud Aviation. Since being introduced to service in 1973, the Gazelle has been procured and operated by a number of export customers. It has also participated in numerous conflicts around the world, including by Syria during the 1982 Lebanon War, by Rwanda during the Rwandan Civil War in the 1990s, and by numerous participants on both sides of the 1991 Gulf War. In French service, the Gazelle has been supplemented as an attack helicopter by the larger Eurocopter Tiger, but remains in use primarily as a scout helicopter.

We want to make it real!

Button

  • Systems and Flight model All systems and the flight model have been simulated from available data in the manuals and tuned to fit real pilots and technicians feedbacks.
  • Rotor System Normal flight phases and autorotation are simulated. The OA209 airfoil has been taken as a reference and then tweaked to fit the real blades lift and drag. Lift and drag coefficients of the OA209 airfoil have been recorded from a wind tunnel simulation. Then the rotor lift and drag are calculated in real time in game. Blades flapping is simulated regarding the real time flight parameters. Rotor Rpm fits the charts when in autorotation.
  • Fuel System The fuel system follows the available charts from the manuals. Fuel consumption is calculated depending on aerodynamics (external loads), weight, atmosphere density, temperature and altitude, flight phase …
  • Flight model All flight phases are simulated : Hover, Linear flight, turns, autorotation. Vortex effect during hovering is functional. Ground effect is functional.
  • Navigation System All real Gazelle navigation devices are simulated : NADIR, ADF Radio, ADF/Sight/NADIR gauge (horizontal situation, ADF and waypoint indications)
  • Radio communication system The AM radio and the Intercom are simulated. The FM radio (PR4G) is also simulated with custom datas and procedures due to its classified aspect.
  • Sounds Sounds of the cockpit have been extracted from original videos recorded by a Gazelle technician. Sounds of the Turbine and the rotor are original as well.
  • Weapons This gazelle simulation features the HOT3 missile and the needed devices to fire it.
  • Video display The TV displays the Viviane sight datas
  • Video command The Video command allows to display the Viviane sight datas.
  • HOT missile console it allows to make the missiles up to fire and is linked to the Video command console.
  • Viviane (APX 397) sighting device external camera linked to the weapon system.

 
  • HOT3 missile wire guided missile, the user has to guide the missile manually to the target until the impact.
  • Warning Receiver The warning receiver system is simulated through the sensors and a display (DRAXX 33) The real symbology is not used due to its classified aspect, a custom symbology is used instead.
  • Flare dispenser The Flaredispenser system includes the Flaredispenser cockpit command (MATRA B0) and the external launcher.
  • Lights system Cockpit lights and external navigation/anti-collision lights are simulated.
  • Damage system The damage system is simulated and includes external visual damages (rotor and blades, fuselage, main cockpit glass…). The effects of the damages are taken in count and change the flight conditions(aerodynamics, lift, speed …). All systems include the damage effects too (electric, fuel, engine …)
  • Multi-Crew The player can swap from the pilot position to the commander position. Missiles can be fired only from the commander position.
  • Performances Maximum speed during linear flight fits the charts. Ceiling fits the charts. Maximum vertical velocity fits the charts. The start-up procedure follows the pilot manual.
  • Autopilot More than a real Autopilot, the Gazelle features a SAS (Stability Augmentation System) This feature is simulated as well in the module, and follows the real functions.
  • Lights All available lights systems from the real model have been simulated, including navigation lights, formation lights, strobe light, extend-able landing light. The cockpit features instruments internal light, UV light and a roof lamp with a move-able red lens so you can have a white or a red light.
  • All this is subject to change and will be updated in time.
