Abstract

The invention provides aerodynamic lift, or downward thrust for the amphibious environment, by means of two conical frames that are opposed at the bases and counter-rotating, thus cancelling out the opposing torque moment when rotating, being provided with concentric rows of fixed and retractable blades having variable angle of attack, arranged along the generatrix, separated by the fixed central area of the frame, where the power plant and the electro-mechanical elements that enable its operation are located, the cabins being situated in the conoidal hollow space of both, thus forming a body of lenticular geometry. The invention is provided with an electro-aerodynamic stabilisation system and landing gear (T), propulsion and manoeuvring being provided by pressurised air supplied through variable-area nozzles, and by the thrust due to the tilting of its axis (Y), with a fairing. Its functions and performance are similar to those of a helicopter.
