Heinkel Lark
Heinkel Lerche was the name of a project study by Heinkel-Werke from 1944/45 for a revolutionary vertical take-off (VTOL) program for the development of an interceptor.
construction
In addition to the features of a vertical take-off aircraft that were also developed elsewhere, such as the nose-up take-off position ( stern take-off ), the unusual arrangement of the rotors, the lying position of the pilot and the wing construction, which is not a conventional wing , but a ring around the propellers rotating against each other, were remarkable provided ( Ringflügler ).
The project studies were completed in March 1945, but the disastrous supply of materials at the end of the war stopped the project. The futuristic design is theoretically airworthy, but unproven. It remains to be seen whether the project would have survived the practical tests.
The sister project was the Heinkel Wasp , a somewhat smaller version that was to be equipped with a turboprop machine instead of two rotors .
