Jacketed Turboprop Engine featuring a set of ring foils: https://lnkd.in/dU4jpmd
European Patent granted: https://lnkd.in/eGwPaKBU
In the take-off phase, the two annular blades of the variable-pitch propeller - yellow and red - generate thrust in the direction of travel and flight respectively, while in flight, when the design speed is reached, only the largest red annular blade generates thrust in the direction of flight.

European Patent granted: https://lnkd.in/eGwPaKBU
The variable-pitch counter-rotating propellers are designed as a turbofan whose two ring blades do not only provide thrust in the direction of flight but also stabilize rotation and ensure quiet engine operation with built-in noise protection.

The animation shows a small Airbus designed by RES for future regional air travel. It has seating for up to twenty passengers. Two electric engines consisting of two counter-rotating propellers with adjustable radial blades and ring wings are positioned at the rear of the aircraft where the laminar flow around the fuselage breaks off. These engines generate thrust in two ways. First, the radial rotor blades generate thrust according to the recoil principle. Second, the two differently sized ring wings generate thrust according to the lift principle. The suction sides of each ring wing align with the fuselage. Since the laminar flow follows the tapered fuselage at the rear, both ring wings are approached at a positive angle of attack. This produces a forward-inclined lift vector, from which a thrust vector acting in the direction of flight can be derived.
