1. A flying vehicle comprising:
- a first rotor mounted so as to rotate about an axis of rotation;
first blades extending from the first rotor along a first blade plane;
a second rotor mounted so as to rotate about the axis of rotation;
second blades extending from the second rotor along a second blade plane;
driving means for driving the vehicle, the driving means including one motor positioned between the first and second rotors and between the first and second blade planes, the motor mechanically connected to the first and second rotors so as to drive the first and second rotors into rotation in respectively opposite directions;
a first crown disposed around the axis of rotation and adapted to rotate about the axis of rotation with the first blades while being mobile relative to the first blades, at least some of the first blades being mechanically connected to the first crown so that relative displacement of the first crown relative to the first blades causes a variation of incidence of the at least some of the first blades; and
a second crown disposed around the axis of rotation and adapted to rotate about the axis of rotation with the second blades while being mobile relative to the second blades, at least some of the second blades being mechanically connected to the second crown so that relative displacement of the second crown relative to the second blades causes a variation of incidence of the at least some of the second blades.

Abstract
A flying vehicle is provided that comprises first and second rotors respectively mounted in rotation about first and second rotation axes, the first rotor including a first group of blades extending in a first blade plane and the second rotor including a second group of blades extending in a second blade plane, each of the first and second rotors being rotated by a driving means of the machine. The driving means includes at least one engine arranged between said rotors and between said first and second blade planes.
