CoAX 2D

Flight Dynamics and Control of Ultralight Helicopters

CoAX 2D in a Low Altitude Turn

In cooperation with edm aerotec GmbH, iFR conducts research on how to make flying helicopters easier and thus safer. The research topics reach from governors to stability augmentation systems in the primary control train.

The CoAX 2D is the first helicopter to receive a type certificate in the new German ultralight helicopter class. It was developed by edm aerotec and has two main rotors, eliminating the necessity of a tail rotor.  Through the cooperation with the manufacturer and with the CoAX 2D being the main testing platform, new algorithms can be tested under realistic circumstances. 

A tethered variant of the CoAX 2D was used in the past to conduct successful flight tests with a stability augmentation system that supports the pilot in hover.
