Beschreibung
Zusammenfassung:	FIELD: mechanical engineering; gas-turbine engines. ^ SUBSTANCE: invention relates to fans and compressors of gas-turbine engines. Blade 14 includes convexity of chords on leading edge between root part 20 and end 22 being swept-forward at end. In other design version chords are increased in length at distance outwards from root part 20 to convexity of blade 14. ^ EFFECT: provision of good delivery of flow and capacity at high velocity. ^ 20 cl, 3 dwg
