Turboprop

A turboprop comprising an air inlet which extends along a directional axis and which is formed so that an operating air flow enters into the turboprop, the turboprop comprising a propeller which rotates around an axis of rotation and which is located upstream of an air inlet with respect to the operating air flow, the propeller comprising at least one blade which, when said propeller is rotated around the axis of rotation, creates a wake which perturbs the operating air flow at the air inlet, said blade extending along a main elongation direction, said blade comprising a root, a leading edge, a trailing edge, and a wing tip, wherein said blade further comprises an inner air flow channel which comprises an inlet which is located at the root of the blade and an outlet which leads to the trailing edge of the blade and which is directed transversely to the main elongation direction, so that an inner air flow which circulates in the inner air flow channel while entering through the inlet in the vicinity of the root of the blade is exhausted via the outlet in the vicinity of the trailing edge of the blade while forming a blown air flow which moves away from the trailing edge in a direction which is transverse to the main elongation direction and which has a component in the direction of a skeleton line of the blade at the trailing edge, the outlet being located at the air inlet so that the blown air flow is exhausted at the trailing edge of the blade so as to reduce the wake of the blade at the air inlet.
