DCS: Black Shark 2 es una simulación del helicóptero de ataque ruso Ka-50 y la siguiente entrada en la serie de combate de Digital Combat Simulator. DCS: Black Shark 2 es una versión muy mejorada del DCS: Black Shark original que aporta muchas características nuevas.

El Ka-50 Black Shark es un helicóptero de ataque ruso monoplaza único y letal que ha combatido en el norte del Cáucaso. Combina un sistema de doble rotor de alto rendimiento con una mortífera carga de misiles guiados, cohetes, bombas y un cañón de 30 mm. El Ka-50 también es único por su asiento eyectable.

Electrical System

Electrical system

The electrical system includes:

  • Main alternating current (AC) distribution system
  • Emergency alternating current (AC) distribution system
  • Direct current (DC) distribution system
  • External electrical power sources for alternating and direct current supply

The Ka-50 electrical power generation system provides AC and DC power to the primary and emergency buses and distribution assemblies. This power supply is used to run avionics systems, internal and external lighting, hydraulic, fuel systems control and monitoring, engines, and auxiliary power unit start up systems. When on the ground, an external power cart can be used as an alternate power source. In addition to onboard power generation capability, the Ka-50 also includes batteries that electrical power can be drawn from.

The Alternating Current System

The primary electrical system is fed by alternating current (AC) 115/200 V, 400 Hz generators. This supply is further divided into left and right systems on independent channels to provide system redundancy. Generator operation is dependent upon the left and right engines being active as each engine contains a gearbox that runs a generator. The left channel systems can be powered by the right generator and the right channel systems are powered by the left generator. In the event of both generators becoming inoperative, a back-up, static DC to AC inverter can take over power to the most important systems and direct current will trigger the in-flight warning system.

The Direct Current System

Systems requiring direct current (DC) power are supplied at 27V by use of AC to DC transformer-rectifiers. Transformer-rectifiers are active while the generators are in operation. If one of the transformer-rectifiers is switched off though, systems will be switched to the operating transformer-rectifier. If both transformer-rectifiers and/or generators are off-line, the most important avionics systems will be switched to emergency DC power.

Damage to the electrical generation system is also manifested in the visual damage model of the Ka-50. An event-oriented approach is implemented such that a loss in electrical power to systems will have a cascade effect. This specifically means that the loss of one electrical system will have repercussions affecting linked elements of the electrical system.

Ka-50 Avionics Systems Overview

Although a highly detailed flight manual will be provided with DCS: Black Shark, the following provides you with a small sampling of the avionics systems modeled in our simulation of the Ka-50. Piloting, navigation, targeting and defensive systems and included in this overview.

Cockpit Instruments

Ka-50 cockpit overview

The Ka-50 cockpit instruments are generally traditional electro-mechanical gauges that are mounted on the front dash and side / back panels. These instruments are divided into three general groups: flight control, engine control/monitoring and systems control. Other cockpit interfaces include traditional switches, dials and multiple-position switches. Additionally, the Ka-50 has multiple banks of warnings lights and cockpit illumination controls.

Advanced Moving Map System AMMS (ABRIS)

AMMS ABRIS display

The ABRIS panel is a multi-function display that allows the pilot to perform the following tasks:

  • Programming, editing and saving of waypoints, runways, radio beacons, target locations and the ability to study terrain along the flight route, etc.;
  • Ability to alter flight plan during mission;
  • Real-time determination of helicopter position coordinates by using of built in navigational satellite system sensor (GPS/GLONASS); display of the helicopter position on the electronic moving map display; ability to cycle map scale; check cross-track error and the other necessary navigation information;
  • Display of aeronautical information and flight plan required for the navigation during all stages of a mission;
  • Reception of information from the autonomous pressure altitude sensors and necessary processing of pressure altitude for the needs of the built-in satellite navigation system sensor;
  • Reception and processing of information from the other avionics systems such as the «Rubicon» targeting-navigation system and data-link equipment.
  • Indicating the position of wingmen using data-link as well as targeting line of sight vector from «Shkval» targeting system.
  • Annotate moving map with text and symbols.

«Rubicon» Targeting-Navigation System

Data entry panel of Rubicon

The targeting-navigation system is designed to integrate combat, navigation and flight tasks by processing both digital and analog information. «Rubicon» is integrated with the «Shkval» targeting system, airborne information display system and weapon control system.

«Radian» Navigation System

«Radian» is a sub-system of «Rubicon» that helps automate flight navigation. «Radian» can store information in its memory such as coordinates for two airfields, six waypoints of a flight plan, ten operative targets, and four reference points.

I-251 «Shkval» System

Targeting complex Shkval
The IT-23 video indicator of Shkval system

The «Shkval» system consists of a television camera combined with a laser range-finder and laser illumination designator to guide the anti-tank missile system.

The «Shkval» system can be ground-stabilizing and is capable of auto-tracking a designated target. There are two Fields Of View (FOV) levels: Wide FOV with a 6x magnification and narrow FOV with a 22x magnification. FOV gimbal suspension limits are: ±35° in azimuth and +15° to -80° in elevation.

The video picture is shown as a gray-scale image on the IT-23VM TV monitor.

The «Shkval» can be set to scan for targets automatically and the angular rate of scan can be manually be set by the pilot while in the cockpit.

To slew the «Shkval» camera, the pilot uses a small mini-stick on the helicopter cyclic.
