The case for a new design of a vertical-axis wind turbine. By Paul Dvorak | October 6, 2010. Air strakes (small wings) on the inside of each blade act like canals that capture and channel the air flow. The devices accelerate and direct the airflow through air jets onto the next blade. This action further assists in blade rotation.

DIY Photon Propulsion – Innovation meets DesignSpark's maker sense. Follow article. VdH 6 Apr 2020. 7 11 6. A typical spacecraft achieve propulsion by reaction engines. They expel gas at their back end. The spacecraft gains the same momentum which the expelled gas mass has gained. This "jet propulsion" is used by most airplanes.

If the efficiencies are like those of a vertical axis wind turbine that works like drag engines, the efficiencies will be far too low. The efficiency would need to be higher than that of horizontal axis wind turbines to reduce the mass penalties for the propellant.

With a vertical axis, the generator and gearbox can be placed near the ground, so the tower doesn't need to support it, and it is more accessible for maintenance. Drawbacks are that some designs produce pulsating torque. Drag may be created when the blade rotates into the wind.
Electric Near Vertical Take-Off and Landing (NVTOL) Aircraft PHRACTYL wanted to build a flying machine using electric propulsion but understood the limitations of current battery technology. As such, they turned to biomimicry and decided to work more on the aerodynamic design of the aircraft until they came up with the fascinating Macrobat concept.
A modern car (drag coefficient 0.34) with a 110 kW (150 HP) engine will be using about 4.6 kW (6 HP) of power to overcome air drag and 11 kW (14 HP) for mechanical propulsion (rolling resistance etc.) when it is being driven at a constant 80 km/h (22.2 m/s, 49 mph).

For vertical flight, the rotors are angled so the plane of rotation is horizontal, like a helicopter. As the aircraft gains speed, the rotors are tilted forward, with the plane of rotation eventually becoming vertical. The wing then provides lift, and the rotor provides thrust like a propeller.
