AIRCRAFT HAVING THE ABILITY FOR HOVERING FLIGHT, FAST FORWARD FLIGHT, GLIDING FLIGHT, SHORT TAKE-OFF, SHORT LANDING, VERTICAL TAKE-OFF AND VERTICAL LANDING

摘要

Aircraft having two, preferably four or more, rotors (20) in wing hatches (10) which can be closed.;The closure mechanism comprises, at the top, individually curved elements on a rollshutter (scroll/roller blind) (40) and, at the bottom, a set of longitudinal fins (30).;The rotors are each driven (50) by one or more motors or engines.;One or more propeller/impeller drives are firmly connected to the stabilator (60), which can be pivoted over a wide extent.;In hovering flight, the wing hatches (10) are opened and the impeller drives (60), together with the stabilator, are pivoted largely vertically downwards.;During the transition to cruise flight, the large flaperons (100) are lowered, and the propeller/impeller drives (60), together with the stabilator, are slowly pivoted to the horizontal. When the forward speed is sufficient, the wing hatches (10) are closed, the rotors (20) are stopped, and the flaperons (100) are raised somewhat again.;The pilot has unobstructed visibility through the gap between the wingtips (70) in all directions of flight, even when components of the wing hatches are in front of the pilot's seat.;The two connected bars shaping a vertex (80) between the wing tips (70) prevent cables from becoming hooked up.;If the rotor system fails during hovering flight close to the ground, the impact is damped by solid-propellant rockets (110).
