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 passenger, cargo service and more. The Tensor cargo gyrocopter has no windows and is specifically for aerial cargo service only. These gyrocopters and newly designed rotor are also scalable depending upon 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 600X 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, wings 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 example 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

The company is aiming for their first flight in 2020 with production of their aircraft later the same year. Customers will be able to purchase Tensor 600X for personal use and for flight training and fly the aircraft immediately because regulations are already in place for gyrocopters. New eVTOL aircraft will need to fight for new regulations to be created and have their aircraft approved by government flying authorities, before they can fly for personal or commercial use.

Fraundorfer Aeronautics goal is to have the two (2) seat Tensor 600X in production by the end of 2020 and the six (6) seat Tensor in production around 2024-2025.
