DCS: Mi-8MTV2 Magnificent Eight focuses on the Mi-8MTV2 – an upgraded version of one of the most widely produced helicopters in history and a combat transport and fire support veteran of countless operations around the world.
Developed by Belsimtek with help from a seasoned Mi-8 pilot, the expert team behind DCS: UH-1H Huey continues to raise the bar in flight and systems modeling.
The helicopter is equipped with lateral, longitudinal, integrated collective pitch-throttle, and directional flight control subsystems. Control inputs are transferred from the cockpit to the rotor blades by mechanical linkages and hydraulic servos. Pilot control is assisted by an automatic flight control system (AFCS) with an integrated four channel autopilot, the hydraulic flight control servos, and pitch, roll, and yaw trim systems. Both the pilot and copilot have collective, cyclic, and directional controls, which are carried by mechanical linkage to the first and second stage control units which combine, sum, and couple the cyclic, collective, and yaw inputs. Resultant output signals are boosted and routed to the main and tail rotors through mechanical linkages with the hydraulic servos.
Lateral and longitudinal control of the helicopter is by movement of the cyclic sticks through push rods, bell cranks, and servos to the main rotor swashplate. Movement in any direction tilts the plane of the main rotor blades in the same direction, thereby causing the helicopter to move in that direction.
The cyclic stick is mounted on the cockpit floor in front of the pilot's seat. The stick assembly is of metal construction and includes a wheel brake lever and lock. The grip includes a three position ICS/RADIO button, an AUTOPILOT DISENGAGE button, a weapons FIRE button, and a TRIM control button. The FIRE button has a guard to prevent accidental activation.
A hydraulic cylinder and mechanical stop are included in the longitudinal control linkage to limit swashplate aft tilt to a maximum of 2°12' when the helicopter is on the ground or taxiing. The stop is controlled by weight-on-wheels microswitches mounted on the main landing gear strut supports. As the pilot pulls back on the cyclic, the longitudinal stop causes a sharp increase in the force required to move the stick when the swash plate aft tilt reaches 2°12'. As the helicopter lifts off the ground, the microswitch contacts open and the stop disengages, releasing the limit on aft swashplate tilt.
