CycloTech UAV Demonstrator

CycloTech UAV Demonstrator
CycloTech GmbH
Linz, Austria

Cyclotech GmbH was found in 2004 in Austria as IAT 21 and has logged more than 15 years of research into its rotor technology. It's core business is the development and optimization of Cyclogyro rotors for gasoline, hybrid-electric or electric vertical takeoff and landing (eVTOL) aircraft. Three patents have been made, another is pending and three more are in preparation (as of June 2020). While the company has already has had investments from Breeze Invest, the company is seeking more financial investors. 

The Cyclogyro rotors are compact, efficient for long distance flight, have precise airflow control during VTOL flight, excellent maneuverability and provide a very stable transition from vertical to forward flight. 

A Cyclogyro rotor has multiple blades about a central axis and which are connected to a rotatably-mounted hub. When more power is applied turning the rotors faster, this generates thrust.  Each rotor wheel is controlled independently allowing almost instantaneous power changes which allow for a more stable aircraft when compared to a plane or helicopter. 

An advantage of the Cyclogyro rotor is it is smaller than standard propellers normally used on aircraft being designed for Urban Air Mobility (UAM) or Unmanned Air Vehicles (UAV). The company states their specialized rotors take up 70% less space and that less space is required per passenger which reduces the costs of operating the aircraft. 

The rotor blades are a familiar propulsion mechanism in the maritime industry called the Voith-Schneider propeller, suitable for use in the aviation industry. 

The UAV proof of concept aircraft is expected for flight test in 2022. The goal of the UAV will be used for inspection flights, search and rescue and border patrols. The company states there is a 20% greater cost benefit of their Cyclogyro rotors when compared to tilt-wing or full electric helicopter concepts.

Cyclotech is also developing a Passenger Demonstrator and Compound Heliopter design.
