Abstract (en)

[origin: WO9507410A1] A propulsion apparatus having at least one converging duct (1) connected to a diverging duct (2). When the apparatus is in motion,fluid flowing through the converging duct (1) converts a portion of its own mechanical energy into propelling energy, which is the product of the thereby generated thrust and propelling speed, whereas fluid flowing through the diverging duct (2) converts its own heat into mechanical energy, thereby cooling the fluid by the amount of work performed by the thrust.
