AIRCRAFT HAVING THE CHARACTERISTIC OF HOVERING FLIGHT, FAST FORWARD FLIGHT, AND 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 mount blind (40) and, at the bottom, longitudinal laminates (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 elevator (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 elevator, are pivoted largely vertically downwards. During the transition to forward flight, the large curved flap (100) is lowered, and the propeller/impeller drives (60), together with the elevator, 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 curved flap (100) is raised somewhat again. The pilot has free 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 tip of a bar (80) between the wing tips (70) prevents cables from becoming hooked up. If the rotor system fails during hovering flight close to the ground, the impact is damped by solid rockets (110).
