A helicopter engine air intake is provided with an anti-icing grating that offers significant bypass flow in the event of icing. According to the invention, this air intake comprises air intake lips (30, 32), and an anti-icing grating (36) mounted on the external ends (30a, 32a) of the air intake lips (30, 32) and which is interposed in the flow of air entering the air intake (34), at least one air intake lip (30, 32) being formed of thin sheet metal.
