THE TECHNOLOGY

A technology developed for building
the safest aircraft generation

 
190423_Fraundorfer_Website_Techniken_CFD

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).
 
 
 
 

The shift of critial areas of application

1
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.
from 180 € / h (-600X)
2
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.
from 150 € / h (single engine airplane)
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"*.
from 450 € / h (single engine helicopter)
i
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.
