Company founder and CEO Chrisoph Fraundorfer has been working on an advanced gyrocopter for the last 10 years with over 20,000 thousand labor hours using modern computational fluid dynamics analysis to optimize the rotor head and airframe.

Their work has paid-off with the company unveiling their full-scale Tensor 600X two (2) seat technology demonstrator gyrocopter on 24 May 2019 at Donauworth Genderkingen Airport in Germany. The company focused on component flight testing taking place before the unveiling of the aircraft so the technology demonstrator would look very close to the production aircraft.

In addition, the company has designed a six (6) seat gyrocopter, the Tensor, for air taxi urban mobility passenger service, search and rescue, cargo and many other types of missions required by slow or fast moving air vehicles. The cargo gyrocopter has no windows and is specifically for aerial cargo service only. The gyrocopters and newly designed rotor are also scalable based on the customer’s needs. The company has patented their new rotor technology and fuselage design.

For more than 60 years, the gyrocopter has been spending time only as a niche market in the hobby sector. Commercial use is not allowed because the low load capacity of the “screwdriver” is a maximum of 450 kilograms. That’s what Fraundorfer wants to change because the gyrocopter basically has one advantage: It can fly slower and lower than a helicopter. In addition, fixed-wing and helicopter pilots can be retrained with little effort.

The Tensor gyrocopter has several unique design features including the ability to use multiple energy sources such as full-electric, gasoline engines, fuel cells or hydrogen engines, main wings with winglets, forward strakes with winglets and a sleek futuristic look. A single propeller connected to a central located engine allows for multiple energy sources. In addition the company has revealed their gyrocopter has a low noise footprint, the cost is low to purchase and operate the aircraft, its ultra-safe and has low emissions.

The company says their aircraft can easily be used for urban air mobility, cargo delivery, air taxi service, search and rescue operations, for some examples and can handle many jobs which helicopters, airplanes and eVTOLs can perform but with less cost, no eVTOL regulation hurdles to jump through and with a quieter noise footprint.

The Tensor gyrocopter has a flight range of 600 km (373 miles) and can fly safely at very ow speeds and at speeds over 161 km/h (100 mph). The company has stated their gyrocopter is quieter than helicopters, light aircraft, drones and eVTOl aircraft. It has one-third (1/3) less drag compared to multicopters and half (1/2) the drag compared to helicopters

Fraundorfer Aeronautics goal is to have the six (6) seat Tensor’s first flight in 2022 with production of their aircraft in the 2024-2025 time frame.
