Abstract
An air induction system for an engine to remove contaminants from intake air prior to delivery to the engine. The system includes an assembly for filtering air which is mounted in advance of the engine, and a duct for delivering air from the assembly to the engine. A sealing system is provided which prevents entry of unfiltered air while simultaneously permitting movement of the engine relative to adjacent parts of the airframe as engine power setting varies. The seal is protected from high pressures in the duct which can occur in operation of the engine.
Claims22
An air induction system for an engine to receive intake air, remove contaminants from the intake air, and provide the intake air for delivery to the engine, the system comprising:
- a housing having a hollow interior with at least one entryway for receiving intake air into the housing, a contaminant separator for removing contaminants from the air, and an exit for discharge of air from the housing;
- a duct positioned adjacent the exit of the housing to receive intake air therefrom for delivering the air to said engine, the duct having an inside defining an internal flow path for intake air and an outside;
- and
- a seal positioned between the housing and the duct for preventing passage of air therethrough;
- wherein the seal is disposed between the outside of the duct and the housing such that the seal is not exposed to air flowing in the internal flow path of the duct.
An air induction system for an aircraft engine to remove contaminants from intake air and deliver the air to the engine, the system comprising:
- a contaminant removal assembly for receiving intake air and removing contaminants from the air, the assembly having at least one entryway for receiving intake air and an exit for discharge of the air from the assembly;
- a duct configured to receive intake air from the assembly for delivery to said engine;
- and
- a flexible and resilient seal positioned between said assembly and the duct for preventing entry of contaminated air;
- wherein the seal permits relative movement between the duct and the assembly in any direction while maintaining a seal between the duct and the assembly.
