THE TECHNOLOGY
A technology developed for building
the safest aircraft generation
Propeller
Propeller is only responsible forforward thrust. CFD analysis and
fuselage optimization have been
performed, allowing a mostly
laminar flow into the propeller.
As a result the system is more
efficient and noticeably quieter.
Wing Lift
At higher speeds the wing providesup to 30% lift and therefore reduces
drag on the rotor which enables the
aircraft to reach speeds of more
than 200km/h.
Rotor Lift
Our rotorsystem uses the energycontained in the air stream to
drive the rotor. It is the same
principle as the maple seed. This
makes rotor lift independent
of the engine and therefore
extremely secure.

Tensor was designed by using state of the art aerospace technology
READ MORE
Fraundorfer Aeronautics invested seven years and 20k man-hours into research of autorotational systems. Mathematical systems have been developed to describe the aerodynamics and make highly efficient airfoil design possible. CFD-Analysis was used to reduce fuselage drag and compare developed rotor airfoils against standard geometries.
The autorotation - a principle designed by nature
READ MORE
Nature uses the principal of autorotation already for a long time. Maple seeds are a prime example of this. Getting behind the secrets and improving existing technological achievements is a challenging task – we gratefully accepted.

Applied Bionics - The Innovation
Our rotorsystem uses the energy contained in the air stream to drive the rotor, as the maple seed does. This makes our system independent of the engine and therefore extremely safe. It took seven years of research to fully understand the autorational principles and develop mathematical systems to design our efficient rotor blade (patent registred).
More secure
Extremely safe due to autorotationand the independence of the engine

More silent
Significantly more silent thanhelicopters or multicopters.

More efficient
30% more efficient compared toexisting autorotation rotors

Target working range for airborne data acquisition Tensor enables you to fly safely, efficiently and above all cost-effectively in the optimum working range for data acquisition.

Range of safe flight conditions. Below approx. 100 km/h a stall occurs and the aircraft crashes. Because of the high minimum speed, an aircraft can hardly avoid obstacles and therefore cannot fly lower than approx. 100 meters.

3
Range in which a helicopter can fly safely. In this range it is possible for the helicopter to achieve autorotation and emergency landing in case of engine failure. It may therefore only be operated here, but not within the "dead man's curve"*.

In the area of the "dead man's curve" if a helicopter's engine fails, it would no longer reach the autorotation state and would therefore crash.

Independency of driving technologies
READ MORE
Due to a single propeller connected to a central located engine, Tensor is able to be fitted with different types of driving engines. When the technology progress allows, electric or H2 driven motors are a viable alternative to conventional chemical systems.
1/3 drag compared to multicopter and 1/2 drag compared to helicopters make Tensor then the most efficient extrem short take-off and landing system available to implement all electric aerial transport.
