Doblhoff WNF 342 : ウィキペディア英語版 | Doblhoff WNF 342 __NOTOC__
The Doblhoff/WNF 342 was the first helicopter to take off and land using Tip jets to drive the rotor. ==Development== The WNF-342 was designed for a German Navy requirement for an observation platform for use from small ships and submarines. The conventional piston engine drove both a small propeller (to provide airflow across a rudder) and an air compressor to provide air (subsequently mixed with fuel) through the rotor head and hollow rotor blades to a combustion chamber at the rotor tips. As a research helicopter it was a simple design to allow modification.
