The invention is directed to a method and arrangement for providing safe vertical landing of airplanes, which are not provided with VTOL equipment or which are hindered with respect to their actual flight capabilities, as well as for providing extrinsically supported zero-run takeoff of airplanes. An airplane equipped with lower takeup means is coupled in flight to upper takeup means carried by a rotary wing aircraft flying above the airplane. The rotary wing aircraft generates the propulsion necessary to transport the airplane and the lifting force and ...
Arrangement for taking up an airplane, which has a fuselage and is at rest on the ground or in controlled flight, with the aid of a rotary wing aircraft, the arrangement comprising: lower takeup means mounted on the airplane; upper takeup means carried by the rotary wing aircraft; remotely-controlled guidance means for guiding said upper takeup means relative to the rotary wing aircraft; coupling-uncoupling means for coupling and decoupling said upper takeup means and said lower takeup means; said lower takeup means being mounted on said fuselage; said c...
