The K-17 was an experimental blade tip propulsion helicopter made by the US manufacturer Kaman Aircraft Corporation .
The turbine produced cold compressed air to drive it, which was then passed through the rotor blades and exited at the blade tips. This set the rotor rotating. The prototype of the K-17 took off in the spring of 1958, but the concept was not pursued any further. Speed and range were clearly inferior to other helicopters of the era.
The concept of the blade tip drive was also used in the Dornier Do 32 and the Boeing X-50 , among others .
