Digital Aeronautics Mi-2 Hoplite Helicopter

The Mi-2 helicopter is an outstanding example of Soviet design.

Produced in Poland in a variety of modifications, it found popularity in many countries due to its multifunctionality and unique style. This meticulously built study-level model is the result of countless hours of research and development by a multi-talented team of professionals.

CUSTOM FEATURES THAT REPEAT ACTUAL REAL-LIFE HELICOPTER BEHAVIOR

Helicopter systems

• Electrical system that accounts for all loads of DC and AC consumers, current, resistance and voltage; load on the batteries, their discharge and charging; realistic behavior of generators when distributing load between them; realistic behavior of converters and their consumers
• Pneumatic system maintains a constant air pressure in the brake system using a compressor installed on the engine, has an air flow rate and is necessary for the operation of the helicopter brake system
• Fuel system accounts for fuel consumption at different engine modes; fuel quantity indicator accounts for the position of the helicopter in space (roll, pitch) repeating the position of fuel in the tank
• Hydraulic system accounts for pressure, temperature, the amount of hydraulic fluid depending on loads and the state of the atmosphere
• Oil system accounts for pressure, temperature, the amount of oil, depending on the operating modes of the engines and the state of the atmosphere
• Fire extinguishing system, including system monitoring and control
• Heating and anti-icing systems allow to monitor the condition of the icing of the helicopter and control the heating of the blades and windows of the helicopter depending on the state of the environment
• Lighting equipment depends on the state of the helicopter electrical system

Helicopter control

• The interaction of the helicopter control knobs fully corresponds to the actual position of the blade angle in different flight modes
• Trimming system allows you to balance the helicopter in a stable position

Engines control

• Implementation of motor control, including separate control
• Engine starting system accounts for the load on the electrical system at the time of starting, the state of the atmosphere and the state of the liquids required for the operation of the engines
• Kinematics of combined control unit of engines RPM and propeller pitch that allows to perform all checks, including engines run-up in accordance with the manual

Instruments

• Aviation clock with second meter repeats the actual behavior of the watch, including all operating modes
• Gyrohorizons have realistic behavior of gyromechanism, including its spin-up and shutdown
• Anaeroid tubes allows realistic behavior of instruments that use them, including the influence of incoming flow and atmospheric pressure
• Devices operating from electric current account for inertia and friction force of needle indicators
• Radio altimeter accounts for slaving and adjustment
• Rotor pitch indicator with realistic behavior during power loss
• Airspeed indicator with response to wind, airflow and direction effects implemented

Interactive cockpit controls

• The mechanical and kinematic behavior of cockpit controls were modeled right up to simulating the operation of the toggle switch spring
• Switches respond to mouse wheel input

Navigation

• ADF allows to navigate by beacons and indicates the magnetic course of the helicopter; this system also implements a simulation of the gyro-magnetic compass operation with a simulation of real slaving

Radio

• Radio unit allows radio communication with ATC at the selected frequency
• Intercom allows to select various listening modes, including ADF signals

Physics and effects

• Atmospheric precipitation realistically displayed on the surface of the windows of the helicopter along with the effect of icing on windows
• Firing signal rockets and smoke generator realized
• Flight model accounts for realistic location of the center of gravity, as well as its influence on the control of the helicopter
• Switching from asymmetric to straight airflow and vice versa causes natural vibration
• Natural deflection of the blades as reaction to the wind in an idle state, the cone of rotating blades changes its size depending on the load on the main rotor

Doors

• Cabin doors fully implemented with individual mechanics for each door
• Interactive opening by dragging the handle with inertia response
• React to helicopter flight dynamics: pitch, acceleration/deceleration, roll, yaw
• Doors may partially open or close in flight if not properly secured  

GAMEPLAY INSTRUCTIONS

VHF allows you to adjust ATC frequencies in multiples of 0.25

Manipulators: combine two modes of interaction:

• mouse wheel - instantaneous state switching

• left mouse button + movement - realistic state switching

• VR - fully adapted, including control of the longitudinal and transverse control knob by moving the controller

• The model includes the ability to automatically start and turn off the helicopter with the preparation of systems in the correct sequence through simulator commands

• To facilitate control, some controls are connected to simulator commands (see manual list)

• When controlling the watch, it is necessary to familiarize yourself with the instructions, since due to the complexity of the implementation, combined control of the manipulators was used

• Due to the realistic implementation of the electrical system and the load on the batteries at the time of starting, the battery charge is enough for 5-6 unsuccessful starts. Due to the fact that it is not possible to replace the battery, the model must be restarted to reset the state of the batteries

• The altimeter has realistic control of the pressure setting handle, which has a reverse direction of rotation (rotation to the right reduces the barometric height, while rotation to the left increases it)

• To remove the helicopter from the parking brake, press the latch on the helicopter control stick or use the simulator command

• The nose steering wheel is made in accordance with a realistic model, and is free castoring (not directly related to the position of the pedals)

• Due to the realism of helicopter centering, restrictions on helicopter centering and loading should be complied with

• For correct display of the helicopter heading on the UGR-4UK device in 3.5 min after starting the helicopter and starting all systems, it is necessary to slave the heading system by pressing the «СОГЛАСОВАНО» button

• For toggle switches with more than 3 positions, to move the toggle switch in the required direction, use manipulator located in the direction of toggle switch movement (wiper toggle switch, АКК/ГЕНЕРАТОР toggle switch)

• Due to the custom implementation of all systems, we do not recommend using default simulator failures

• Audio and Immersion

• Wwise fully dynamic sound pack

• Sound of engines, systems and other controls
