Apparatus for disposal of leaking fluids in a turbofan engine

摘要

This invention relates to apparatus which harmlessly purges all fluids which leak from the fittings of a turbofan aircraft engine. Purging is achieved by passing a low speed flow of ventilating air along the exterior walls of the engine combustor section. This is accomplished by enshrouding the engine core with a cylindrical cowl. A space between the cowl and the engine combustor makes an annular shaped cavity. Ports in the cowl allow air to be brought into the cavity from the bypass ducting of the engine. The rapidly moving volume of air thus brought in vaporizes any fuel which leaks into the cavity. The vaporized air/fuel mixture is then exhausted into the hot gas plume emitted from the rear of the core engine.
