초록

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...

청구항

In combination with a turbofan engine having a leaking fluid disposal apparatus of the type wherein ventilating air from the bypass ducting is drawn through ports in the cowl separating the bypass ducting and the core engine stages, the cowl having at its midsection in the area containing the engine fuel lines, a diameter sufficient to form between said cowl and said core engine stages an annular shaped cavity through which said ventilating air flows, and wherein means are included for exhausting the combination of ventilating air and vaporized leakage f...
