摘要： Apparatuses are provided for reducing noise generation from a dead ended conduit in a gas turbine engine. In particular A scooped bellmouth is provided that comprises a bellmouth within a surface having an outer perimeter an inner perimeter and a ramp diverging from the surface at a first end, the ramp extending radially through the outer perimeter of the bellmouth at a second end. The ramp diverts an airflow away from the bellmouth thereby preventing the development of a low pressure area at the bellmouth without affecting the efficiency of the gas turbine engine.

摘要： A fireproof system is provided for protecting a structure during a fire event. The system includes a fire resistant panel defining a first attachment opening and disposed adjacent to the structure; a canister including a side wall defining a first end and a second end, and an end wall enclosing the first end and defining a second attachment opening that is aligned with the first attachment opening; a fastener extending through the canister at the second attachment opening and the fire resistant panel at the first attachment opening such that the canister, the fire resistant panel, and the structure are fastened together; and a fire retardant agent disposed within the canister in an inactive condition and configured to transition out of the second end of the canister in an active condition at a predetermined temperature.
