The cascade turbine can be used either as a turbofan engine for aircraft with a combustion chamber, as illustrated in the patent document, or as an electrically driven air compressor, as shown in the video clip. It is equipped with fixed annular guide vanes that influence the flow into the circular blades. The circular blades of the annular fan are swept by the airflow at a positive angle of attack, thereby generating thrust in the direction of flight. In the direction of flow, there are several compressor stages, each consisting of a smaller donor ring blade and a larger receiver ring blade downstream of it. The aircraft also features a new manoeuvring system in which a change in the distance between the hinges mounted at the nose and tail causes the angle of attack on the front and rear wings to change in opposite directions, enabling the aircraft to manoeuvre with precision.

The video shows a fully electric cold-air aircraft propulsion system. The body of a van, which is several metres in size, acts as a tail section, directing the airflow towards a ring-shaped wing comprising radial rotor blades with a positive angle of attack. This generates thrust in the direction of flight. The radial rotor blades are designed to direct air into a downstream compressor comprising several compression stages. Each compressor stage consists of a smaller, rotating ring-shaped blade that connects the radial rotor blades and acts as a donor to a larger, counter-rotating, ring-shaped blade. This blade is swept by the donor with a positive angle of attack, generating thrust in the direction of flight within the compressor stage. As in a conventional jet engine, the air accelerated and compressed in the cold jet engine is expelled rearwards to generate thrust in the direction of flight according to the principle of recoil. The radial flow machine used for propulsion has a matrix circuit corresponding to another of the author's inventions.
