BLADE OF AERODYNAMIC MODEL OF PROPELLER Russian patent published in 2016 - IPC G01M9/08 B64C11/16 B64C27/46

Abstract RU 2578832 C2

FIELD: aviation.

SUBSTANCE: invention relates to design of blades of propeller aerodynamic models for testing in wind tunnels. Blade of aerodynamic model comprises top and bottom envelopments, spar, inserts, balancing and counter flutter weights and nasal pad. End part of blade comprises one or several ribs, attached to spar rear wall, and root part is attached to rear wall of spar power element, including power lug and power rib box-like shape with fixed between insert part of tail part of blade.

EFFECT: higher rigidity of root and end parts of blade of aerodynamic air propeller model.
