NACELLE AIR INTAKE AND NACELLE CONTAINING SUCH AIR INTAKE Russian patent published in 2023 - IPC B64D33/02 F02C7/04 F02C7/47 

FIELD: aircraft power unit.

SUBSTANCE: air intake (3) for the nacelle (1) of the engine (6) of the aircraft contains a leading edge (31), a cylindrical inner wall (32), a cylindrical outer wall (33), a front mounting flange (34), a rear flange (44) of the turbojet wall engine. The air intake (3) has a downstream end of the outer wall (33), configured to be placed in the connection area flush with the front end of the outer casing (43) of the fan (5). A portion of the outer wall (33) rests on a support surface (51) of a support structure (50) configured to be attached to a wall of a turbojet engine forming a fan casing (42), such that this attachment is located longitudinally rearward downstream of the mounting flange (34), in assembled position. The support structure (50) is configured to be attached to the wall of the turbojet engine, forming a fan casing (42), so that the force path, in the assembled position, passes directly from the outer wall (33) to the fan casing (42), while avoiding the inner walls (32).

EFFECT: improved aerodynamics and increased structural rigidity are achieved.
