Korsun O.N., Burlak E.A., Nabatchikov A.M., Kharkov V.P. The methods of intellectual operator support of remotely piloted aircraft based on the concept of a triangle of power // Восьмой Международный Аэрокосмический Конгресс. Тезисы докладов. – М.: АИР, 2015. – С. 88.
This work is intended to raise awareness of the human operator on the parameters of movement by RPV (remotely piloted vehicle) indication limiting operational constraints using the concept of a triangle of power, based on the balance of energy and aircraft engine.
The paper proposes a new approach to display the limit values of RPV flight parameters on the basis of the energy balance and consideration of parameters such as the angles of trajectory θ and roll γ, i.e. the coordinates of the state that on a given flight speed requires an increase the thrust for the acceptable range of values.
The geometric interpretation used the equilateral triangle, which is called the triangle of power. The height of the triangle will be interpreted as the amount of thrust propulsion system. On the sides of the triangle in a certain scale are the values of the flight speed V, roll γ and angles of trajectory θ. We use the property of an equilateral triangle - the amount of perpendicular laid out arbitrary point on the inner side is constant and equal to the height of the triangle. Then we can say that the length of the perpendicular dropped on the sides of the triangle are proportional to the current value of the thrust needed to create V, γ and θ.
Areas of use of this approach:
The advantage of the method is to provide a visual and imaginative display of limit values of flight parameters (angle of pitch, roll and speed) and the relations between them, making it easier RPV operator (or the pilot of aircraft) flight image formation and evaluation of opportunities to maneuver without exceeding the maximum permissible values of flight parameters .

Areas of use of this approach:
- intellectual support of the operator's actions in RPV control;
- intellectual support of pilot actions in aircraft control;
- support activities of design engineers of aircraft control systems and test engineers due to visual and figurative representations of aircraft flight limitations and maneuvering capabilities.
The advantage of the method is to provide a visual and imaginative display of limit values of flight parameters (angle of pitch, roll and speed) and the relations between them, making it easier RPV operator (or the pilot of aircraft) flight image formation and evaluation of opportunities to maneuver without exceeding the maximum permissible values of flight parameters .
