Tensor 600X gyrocopter launched at European Rotors

A brand new gyrocopter is being launched at the European Rotors show and conference which opens in Cologne today.

German technology company Fraundorfer Aeronautics is introducing the Tensor 600X which it claims has a range of 600km (324nm) and a max cruise speed of 200km/h (108kt).

Fraundorfer says the Tensor 600X is twice as efficient as a comparable helicopter thanks to its R01 High Performance rotor system, which works with a wing to create lift. The wing supplies 30% of the lift at cruise speed, reducing drag from the rotors, according to Fraundorfer.

The Tensor 600X has flown, making its first flight back in January 2020. It is currently undergoing certification and the first production aircraft are being built.

Christoph Fraundorfer, founder and CEO of Fraundorfer Aeronautics, and a graduate of the UK’s Empire Test Pilots School, said, “When we founded Fraundorfer Aeronautics, we wanted not only to bring the beauty and efficiency of flight into everyone’s daily lives, but also, and more importantly, to enable environmental and disaster relief missions that were previously infeasible.

“We have been performing unsolved, highly complex aerodynamic calculations for decades. After seven years of risks and challenges, we’ve made a breakthrough.”

Fraundorfer also says the Tensor is a scalable concept. By mid-decade, the company will launch the larger Tensor 800X, which will be certified under European aviation regulations and capable of commercial operations.

Although the launch aircraft will be powered by a Rotax 915iS engine, Fraundorfer says the Tensor 600X could easily be adapted for a hybrid power unit or hydrogen fuel cell.

Comments

  1. Would be interested to know why the wing is heavily swept; at these speeds a straight wing is significantly more effective/ efficient

  2. Legal action against Mr. Christoph Fraundorfer are running. He was a major person around the failed Arrowcopter project. He is under NDA by Waidhofer DiNelly. A lot of innovations are copied from the DiNelly eXoRotorcraft Products.

  3. Thank you Robt, for your comment. You are absolutely right, at these speeds wings without sweep would be more efficient. But we had to deal with different challenges: The wings are swept to additionally increase the directional stability and the yaw- roll coupling. Other points were to bring the aerodynamic center on the right position, to be able to combine wing and main landing gear strut and not least to enable a very good field of view for pilot and copilot. Unfortunately, aircraft design is always a compromise.
    Happy landings,
    Christoph
