Heinkel Lerche
From Wikipedia, the free encyclopedia
The Heinkel 'Lerche' (German:"Lark") was the name of a set of project studies made by German aircraft designers Heinkel in 1944 and 1945 for a revolutionary VTOL fighter and ground-attack aircraft.
The Lerche was an early coleopter design. It would take off and land sitting on its tail, flying horizontally like a conventional aircraft. The pilot would lie prone in the nose. Most remarkably, it would be powered by two counter-rotating propellers which were contained in a donut-shaped annular wing.
The remarkably futuristic design was developed starting 1944 and concluding in March 1945. The aerodynamic principles of an annular wing were basically sound, but the proposal was faced with a whole host of unsolved problems of manufacture and control which would have made the project highly impractical even were it not for the materials shortages of late World War Germany.

[edit] Trivia
A virtual version of the Heinkel Lerche is available as a flyable aircraft in the simulation game IL-2 Sturmovik 1946
The virtual version is equipped with 2 30mm MK 108 cannons and 3 experimental X-4 Proximity rockets which explode when near another aircraft. It can exceed 550 km an hour, and is highly maneuverable.
