Bombardier has filed a patent for an air intake insert for a suction duct. The insert includes an inner portion that extends within the duct, a mating portion for sealing the air intake, and an outer portion that extends outside the duct. The inner portion features a conduit with a non-parallel inlet and outlet direction, and the outlet end has a smaller cross-sectional area than the duct. The outer portion has a curved lip to direct airflow into the inlet opening. GlobalData’s report on Bombardier gives a 360-degree view of the company including its patenting strategy.

An insert for an air intake of a suction duct
A recently filed patent (Publication Number: US20230271708A1) describes an insert for an air intake of a suction duct. The insert includes an inner portion that extends within the suction duct and has a conduit with opposed inlet and outlet ends. The outlet end has a smaller cross-sectional area than the suction duct and a jagged trailing edge defined by spaced apart notches. The insert also has a mating portion that engages the air intake, with the inner portion extending inwardly from the mating portion. Additionally, there is an outer portion that extends outside of the suction duct, with an inlet in fluid communication with the inlet end of the conduit. The outer portion includes a curved lip surrounding at least part of the inlet opening, defining a leading edge of the inlet.
The patent also claims that the conduit of the insert has a central axis extending along an inlet direction at the inlet end and along an outlet direction at the outlet end, with the inlet and outlet directions being non-perpendicular. Furthermore, the inlet has opposed first and second sides, with the first side being closer to the outlet end of the conduit than the second side. The lip forms a protuberance along the first side.
The patent further describes an assembly that includes a suction duct and the insert received in an air intake of the suction duct. The inlet of the insert defines part of the mating portion and has an external shape complementary to that of the air intake. In another assembly, the outlet end of the insert is aligned with a central axis of the suction duct.
In summary, the patent describes an insert for an air intake of a suction duct that includes a unique design with a jagged trailing edge and a curved lip. The insert is designed to be received in an air intake of a suction duct and can be part of an assembly with a suction duct. The design of the insert allows for improved airflow and sealing engagement with the air intake.
