Encyclopedia > Heinkel Lerche

The Heinkel 'Lerche' (Ger.:"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. German (called Deutsch in German; in German the term germanisch is equivalent to English Germanic), is a member of the western group of Germanic languages and is one of the worlds major languages. ... Genera Mirafra Pinarocorys Heteromirafra Certhilauda Chersomanes Eremopterix Ammomanes Alaemon Ramphocoris Melanocorypha Calandrella Spizocorys Eremalauda Chersophilus Galerida Pseudalaemon Lullula Alauda Eremophila Larks are passerine birds of the predominantly Old World family Alaudidae. ... Heinkel Flugzeugwerke was a German aircraft manufacturing company founded by and named after Ernst Heinkel. ... Vertical Take-Off and Landing (VTOL) describes airplanes that can lift off vertically. ...


The Lerche 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 propellors whcih 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.
