Definitions

• the helicopter is very expensive but also makes noise and has a low safety index over time, because of the blades of the rotor which undergo by a set of rods, different inclinations at each turn controlled by the collective handle.
• the present application is to take into account an approach adapted to aviation which by rigid wings constrains and imposes its flight area in demanding and non-modifiable configurations.
• a specific modification to the principle of known aircraft technologies that represents the abandonment of fixed wings for the benefit of a double rotary wing constitutes the present application named Pica-Gyr.
• Our planes behave with a mechanical rigidity that leads us to crashes, by default as soon as we go out of the rules.
• the flight configuration becomes a difficulty, a maneuverability unfit for the circumstances, that our brain learns, but which is not natural, the tool of the rigid wing does not adapt to the useful speeds, different on the same plane, it imposes minimum speeds, and behaviors to which we must conform, respect, in spite of all circumstances. More flexible behaviors with levitation variables make it possible to adapt flight configurations, and practical demands, with greater ease, ensure high speed translations and safe vertical departure.
• the resolution of the equation, of the request for flexibility of use is the integration of an editable parameter of the lift by modification of the piloting of the speed of the rotary wing, piloted with at least one independent engine for this purpose or coupled with that of the translation.
• the principle of the double rotary wing is in fact the main adaptable lift technique in the known aeronautical field, it replaces the fixed wing of the aircraft, as indicated by the PCT anteriority N ° FR 2009/001017 of 20/08 / 09. Whether the engine is in reverse thrust of the aircraft Fig.l or pulls the aircraft ahead of the cockpit Fig.2, with one or more propellers, the configuration presented provides the resolution of the vertical flight and the fast flight, with at least a piloted engine.
• FIG.l We illustrate an aircraft Fig.l, consisting of (sets of rotors (1, 2), rotating wings whose blades of each rotor rotate in the reverse direction of one another to obtain a balance of levitation forces without gyroscope effect that vanishes with both counter-rotating rotors in action.
• the engine (5) we use the engine (5) to launch the rotors and the blades (1, 2), which ensures the takeoff.
• This device made by those skilled in the art, with the techniques currently available, can control the rotors and take off vertically.
• the torque converter controlled from the pilot cell activates in reverse mechanical rotation (6) the blades of the rotors (1.2) until during the translation, the autorotation suspends the aircraft.
• This converter makes it possible to transmit the minimum useful energy of the motor (5) to ensure the lift.
• the piloting allows the engine (5) to translate its power to the propeller (4) horizontal thrust, which gives the speed of translation and allows to advance the aircraft that ensures its own lift without the need energy and disengages automatically at a naturally maintained minimum speed.
• the blades of the rotors are constant pitch, or variable but without a cyclic system, which would make the technology very fragile and noisy. Both rotors Fig. 1 (1,2) are concerned with the variable pitch to decrease, adapt the drag to high speed. From the cell (3) the controls allow steering, actions for flying with high visibility, as directed by those skilled in the art.
• This lift by the integration of two superimposed rotors with at least two blades constitutes the rotary wing driven with the engine connection.
• the vertical air flow of the rotors is controlled by two vertical articulated flanges. 2, (7) arranged along or behind the cell to compensate for, manage roll.
• This device responds to a dual simultaneous equation that is a lift at zero speed or low translational speed, and provides the minimum drag for the high translation speed, which can not achieve a fixed wing.
• the pale (1) Fig.3 are short and wide to provide sustenance, with a profile that the skilled in the art develops for the occasion.
• FIG. 2 represents a conventional aircraft equipped with the double rotor (1, 2) activated by the thrust motor (3) of the front propeller (4), the position of the propeller in front ensures a more intense stability and more sure that the back thrust, it is up to the person skilled in the art to propose the most suitable solution if necessary.
• the empennage and its control surfaces (5, 6) remain conventional. The speed exceeds 400km / h because of a very low drag and the minimum lift guaranteed, the blades being calculated for the maximum speed and the smallest drag.
• the method of calculation of the blades deals with lift at takeoff which will be adjusted, adjusted by the rotation of the rotors, which completely changes the calculation of the fixed wings.
• This filing concerns conventional aircraft with engines and propellers or turbines that mutate in rotating wings and adapt to the parameters of hover and fast flight, which also meets the criteria of economy, efficiency and the environment by less noise, the cyclic pitch not being used. Higher efficiency and reduced consumption are achieved due to reduced forces and vibrations.
