FIELD: aircraft engineering.
SUBSTANCE: disc craft airframe connected without transmission with load-bearing thin disc that makes the flywheel and doubles as s cowling equipped with adjustable radial blades with ends pivoted with the disc. Blades nearby the disc periphery have structural surface expansions directed toward disc rotation. Sector wings are fitted between blades. Said blades make slats and flaps of sector wing. Blade area-to-disc area ratio makes 0.05-0.1.
EFFECT: improved aerodynamics.
