FIELD: aerospace engineering.
SUBSTANCE: invention relates to aerospace engineering. Proposed flying craft helical activator propulsor consists of the engine, frame, helical activator (10), working spring (11), tube designed to orient working spring on contracting, rod that enters the said tube and pushing surface. The rod and tube interact in turn to contract and release the said working spring during 3 to 5 revolutions of helical activator so that the said pushing surface generates jet thrust due to repulsing air downward.
EFFECT: reduced costs of manufacture.
