CONTRACTED SELF-LIFTED DEVICE

摘要

Novelty: a contracted self-lifted device suitable for the take-off of flying engines (airplanes, helicopters or other flying vehicles). Constitution: a propeller 1 rotating inside a container 2 having its top 3 open and bearing the air exhaust nozzles 5 positioned at different distances (ha, hb, he, hd) from the top 3. Due to the said propeller and the air exhaust nozzles encountered at different distance from the top of the container, the pressure featured inside this container is getting reduced from the upper end to the bottom of the container so that a lifting force is generated by the differentiated pressure featured between the inner and outer surface of the bottom 4 of the container.
