Helischool - The virtual flightschool
How flies our helicopter?
A simple statement
An aircraft must fly forward, so that the air circulate around the wings and created the buoyancy. The blades from the helicopter rotate continuously in a circle and allowed the flies without the helicopter move.
A motor rotates the rotor with high power against the resistance of the air. In counterforce the rest of the heli wants to rotate opposite. The tail rotor prevents this, while it take against his force.
The blades of the main rotor are rotated by the control and raise more or less the helicopter. Who hold his hand at driving as a wing out of the car-window, could feel the 'bearing' if he turns it differently against the wind.
With the control the pilot could pitched the main rotor in all directions. The rotor raises and drags the rest of the helicopter behind him.
Controlling is everything
That sounds very unstable - and it is. An uncontrolled Heli begins immediately to drift in any direction, accelerates and crashes after a few seconds on the ground.
Some pilots compare the helicopter flies, therefore, with the balancing from a broom on the tip of the nose. You should never look to the other way - not for a second. High concentration is required.
The Control
In large, as in the model helicopter there are the same control functions:
- Nod to the front and rear (transverse axis)
- Rolls to the left and right (longitudinal)
- Yawing (turning) of the helicopters to the left and right (vertical axis)
- Pitching top and bottom (descend and decrease)
Those are four dimensions. We humans have three typicial usual, because we can not even fly. The addition of learning climbing and fall makes us great effort and should required weeks and months, depending on the time spent. We help ourselves by using a gyroscope (gyro), who takes the controlling of the vertical axis to 95%.
On the individual parts of the control elements, we won't be addressed on this issue. Moreover, there are thousands descriptions on the Internet and on the instructions of your Heli.
The remote control (for right)
has by a helicopter two control sticks with four axes:
The right:
- front and back controls nod back and forth.
- left and right controls roll left and right around the longitudinal.
The left:
- front and back controls pitch, or rotation speed or both. Forth is decreasing, back is descending.
- left and right controls yawing, also turning the heli around the rear axle via tail rotor.
More functions are possible:
- Channel 5: gyro sensitivity - with sliding controller
- Channel 6: engine on - off - with switch or slider
