Design Evolution and Development
Jochen Steinbeck designed the Cloud Dancer 2 as an evolution of Rotortec's single-seat Cloud Dancer 1, addressing the growing demand for practical two-seat autogyros in the European general aviation market. The aircraft underwent significant modifications during its development phase, most notably the transition from a three-bladed to a four-bladed main rotor system. This change improved vibration characteristics substantially, though it required larger hangar space for storage.
The development team at Rotortec prioritized creating a turnkey aircraft solution, departing from the traditional kit-built approach common in the autogyro market. This philosophy led to the integration of modern avionics systems, including a standard electronic touchscreen instrument panel that brought contemporary cockpit technology to the gyrocopter segment.
The Manufacturer
Rotortec operates from Görisried in the Allgäu region of Bavaria, specializing exclusively in autogyro development and production. The company distinguished itself in the industry by developing proprietary powerplant technology rather than relying on automotive conversions or traditional aircraft engines. This vertical integration approach allowed Rotortec to optimize engine characteristics specifically for autogyro applications.
The Bavarian manufacturer remains active in the current market, continuing to produce aircraft and support existing operators. Rotortec's focus on the autogyro niche has positioned the company as a specialist manufacturer in a segment dominated by kit aircraft and smaller operators.
Engine and Technical Innovation
The Cloud Dancer 2's powerplant represents one of its most significant technical achievements. Rotortec's MPE twin-cylinder, four-stroke engine produces 135 horsepower through turbocharging, delivering power through a planetary reduction drive to a three-bladed composite propeller in pusher configuration. This in-house engine development provided the manufacturer complete control over powerplant characteristics and maintenance support.
The aircraft's micro-processor controlled hydraulic pre-rotator system automates the critical rotor spin-up process, reducing pilot workload and improving safety margins. With an empty weight of 248.5 kilograms and a maximum gross weight of 450 kilograms, the Cloud Dancer 2 offers a useful load of 201.5 kilograms while maintaining structural integrity through its aluminum and Kevlar composite construction.
Performance Characteristics
The Cloud Dancer 2 achieves a cruise speed of 165 km/h at its normal operating weight, with a maximum speed capability of 190 km/h under optimal conditions. Its rate of climb reaches 6 meters per second, providing strong performance for an autogyro in this weight class. The aircraft's 115-liter fuel capacity supports extended range operations while maintaining reasonable payload flexibility.
The 6.7-meter rotor diameter with 17.5-centimeter chord blades provides efficient lift generation across the aircraft's operating envelope. The four-blade configuration, while requiring more storage space than the original three-blade design, delivers smoother operation and reduced cabin vibration levels that enhance passenger comfort during extended flights.
Operational Applications
Beyond recreational flying, the Cloud Dancer 2 has found specialized applications in aerial survey and remote sensing operations. Its low operating costs and stable platform characteristics make it economically viable for tasks requiring extended loiter times and precise flight paths. These commercial applications demonstrate the aircraft's versatility beyond the traditional sport flying market.
The aircraft's enclosed cockpit design extends its operational envelope compared to open-cockpit autogyros, allowing year-round operation in European weather conditions. The side-by-side seating configuration facilitates training operations and recreational flying partnerships.
Current Status and Preservation
At least one Cloud Dancer 2 is preserved at the Hubschraubermuseum Bückeburg in Germany, ensuring the type's representation in aviation heritage collections. The museum display highlights the aircraft's significance in modern German aviation development and autogyro evolution.
Rotortec continues producing the Cloud Dancer 2 as market demand warrants, maintaining parts support and technical assistance for operators. The aircraft represents a successful integration of modern technology with traditional autogyro principles, demonstrating that innovative design approaches can advance even mature aviation segments.
