Ewa Roszkowska,Tomasz Wachowiczeleration can arise either by driving a system of rotating vanes, or by releasing heat directly into the fluid flow within a duct coupled with change in cross-sectional area along the axis of the duct. The former method is employed with the combination of aero piston engine and propeller, and the la
