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 contra-rotating propellers which were contained in a donut-shaped, nine-sided 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 manufacture and control problems which would have made the project highly impractical, even without the material shortages of late-war Nazi Germany.

Heinkel Lerche war der Name einer Projektstudie der Heinkel-Werke aus den Jahren 1944/45 für ein revolutionäres Senkrechtstarter-(VTOL)-Programm zur Entwicklung eines Abfangjägers. Es existierten zwei Ausführungen: die als leichter Jäger mit einem Triebwerk ausgerüstete Lerche I und die schwere Nachtjagdvariante Lerche II mit zwei Motoren.- [en] Heinkel Lerche

Le Heinkel Lerche est un intercepteur allemand expérimental de la fin de la Seconde Guerre mondiale. Il fut étudié en 1945 par le constructeur aéronautique allemand Heinkel. Il ressemblait à une fusée, il devait décoller et atterrir à la verticale.Il n'a cependant jamais volé. Sa structure révolutionnaire devait réduire considérablement la traînée de l'avion et ses doubles hélices lui offraient une vitesse considérable (800 km/h) et un taux de montée qui devait l'amener à son plafond de vol en quelques minutes.[it] Heinkel Lerche
L'Heinkel Lerche ("Allodola") era il nome di una serie di progetti sviluppati dall'azienda aeronautica tedesca Heinkel tra il 1944 ed il 1945 per un rivoluzionario aereo da caccia e da attacco al suolo posacoda a decollo verticale per equipaggiare la Luftwaffe durante la seconda guerra mondiale.[ru] Heinkel Lerche
