Heinkel Lerche - German Paper-Project Interceptor

One of the most famous of the German 'wunderwaffe' aircraft created during the final months of the Second World War is the Focke-Wulf Treibefugel, which has become iconic for its rocket-powered propeller blades and vertical takeoff/landing. Lesser-known, however, is the Treibefugel's more conventional brother from Heinkel, the Lerche.

A follow-up design to the quite similar Heinkel Wespe, the Lerche (Lark) was designed as a coleopter interceptor which would be able to tackle American and British bombers with the same effectiveness as the conventional interceptors, like the Focke-Wulf 190 (+ the Ta-152) and Heinkel 219, omitting the need for a conventional runway which would be a prime target for Allied bombers. The design, which was completed on March of 1945 - only two months before the end of the war, was armed with twin thirty-millimeter MK 108 autocannons and powered by twin DB V12 engines running to twin, contra-rotating propellers. The pilot would be standing while taking off or landing and prone while in flight. However, given the impracticality of the design, the shortage of German materials, and the two months between the finish of the design and the end of the war, this Lark never flew.

A bit of a complex file - everything can be printed in FDM at preferable 0.1mm layering, but the assembly (mainly attaching the shroud) is fiddly. The propeller rings should be placed at opposite orientations (because contra-rotating) and do not have to be glued to allow them to spin. The shroud around the propellers needs to go over the bottom wing... things? and just goes under the top wings. Good printing!
