Title:
INLET CONE AND AEROENGINE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2024/022304
Kind Code:
A1
Abstract:
An inlet cone. The inlet cone comprises a body (2) and a nose cone portion (1), wherein the body (2) comprises an outer wall (21), and the nose cone portion (1) is connected to an end of the outer wall (21); an outer surface of the nose cone portion (1) has a first contour line (3), an outer surface of the outer wall (21) has a second contour line (4), and the second contour line (4) is bent and contracted towards the axis of the body (2) in a direction away from the first contour line (3); and cold air flows towards the rear outer wall (21) along the outer surface of the nose cone portion (1). Since the outer surface of the outer wall (21) is bent and contracted towards the axis of the body (2) in the direction away from the first contour line (3), an air stagnation zone is formed between an extension line of the first contour line (3) and the second contour line (4), and less cold air flows in the air stagnation zone, that is, the heat taken away by the cold air from a surface of the outer wall (21) is correspondingly reduced, such that the outer wall (21) of the inlet cone is not prone to icing up, and the engine efficiency is improved.
