Exhaust duct assembly with welded duct, stiffener, and connector
A recently granted patent (Publication Number: US11905844B2) discloses an exhaust duct assembly designed for use in aircraft, comprising a case with an inner space, a duct with an inlet and exhaust port for exhaust gas, a stiffener to attach the duct to the case, and a connector on the exhaust port. The components are welded together in a specific configuration where they overlap in a first direction, ensuring a secure connection. The stiffener and connector have specific connection ends that are welded to each other to form welding parts, providing structural integrity to the assembly.
Furthermore, the patent details the sequential arrangement of the duct, stiffener, and connector in the first direction, with specific welding parts formed at the connection ends. The connector features a step structure to accommodate the varying thicknesses of the connection ends, ensuring a proper fit and alignment. The exhaust duct assembly is specifically designed for use in aircraft with gas turbine engines, providing an efficient and secure means of exhausting exhaust gas. The unique welding configuration and structural design of the assembly contribute to its reliability and performance in the demanding aerospace environment.
