METHOD OF MANUFACTURE OF BLADES AND SPARS FOR FLYING VEHICLE PROPELLERS AND OTHER ARTICLES FROM COMPOSITE MATERIALS Russian patent published in 1998 - IPC

FIELD: aeronautical engineering. SUBSTANCE: method consists in winding the composite material tape impregnated in binder on mandrel to obtain blank of required thickness followed by polymerization of material. Installation of parts is effected after winding the tape according to its position, for example, mounting of counter-weight in nose section of blade which has been preliminarily placed in technological envelope with fixing wings; then winding is continued together with part mounted, after which article is subjected to polymerization. EFFECT: enhanced reliability of attachment of counter-weight, reduced labour consumption and consequently cost of article; increased service life of blades. 5 dwg
