FIELD: aircraft engineering. ^ SUBSTANCE: invention relates to aircraft engineering. Proposed flying craft consists of the frame to throw pilot and cargo upward, internal combustion engine and propulsor. The latter comprises activator and working spring to be compressed and released by helical activator, dome and slightly bending strips designed to produce inertial force and to push air away so that to produce reactive force, when helical activator makes 3 to 5 rpm drive by ICE. ^ EFFECT: expanded performances. ^ 1 dwg |
