The Merckle SM 67 was the first German helicopter powered by a turbine .
history
The order for the development was given in 1957 by the Federal Ministry of Defense. In terms of design, it was similar to the Alouette II . The first test model successfully completed its acceptance flight on July 7, 1959. The remarkably low vibration level was highlighted in the acceptance report, as was the good controllability and stability. Two more test machines followed, in which the experience gained with the prototype was taken into account. One machine was destroyed in an accident during testing.
The fact that the Bundeswehr decided in favor of the SE-3130 Alouette II in the competition for a 5-seat liaison helicopter was mainly due to the earlier availability of the model.
Whereabouts
The test sample V2 was then used at MBB as a test bench for components of the Bo 105 . Together with the other, still preserved test model V3, it was later put together to form the machine that can be viewed today in the Bückeburg helicopter museum .
