Abstract: A ring vane nozzle for a gas turbine engine according to an exemplary aspect of the present disclosure includes a multiple of fixed turbine vanes between an inner vane ring and an outer vane ring and a multiple of rotational turbine vanes between the inner vane ring and the outer vane ring, each of the rotational turbine vanes rotatable about an axis of rotation.

Abstract: A process for casting a turbine engine component is provided. The process comprises the steps of placing a refractory core assembly comprising two intersecting plates in a die, encapsulating the refractory core assembly in a wax pattern having the form of the turbine engine component, forming a ceramic shell mold about the wax pattern, removing the wax pattern, and pouring molten material into the ceramic shell mold to form the turbine engine component.

Abstract: The fuel spray device is adapted for use in the thrust augmentor or afterburner of a gas turbine engine. The fuel spray device includes a fuel spray manifold having a plurality of spaced apart ejection orifices and a plurality of nozzle pintles each having a decreasing cross-sectional portion, such as a conical portion, against which the orifice wall seats when there is no fuel pressure and relative to which the orifice wall moves as fuel pressure increases to increase fuel flow rate and each pintle having a substantially constant cross-sectional portion, such as a cylindrical portion, downstream of the conical portion to accommodate movement of the orifice wall of the manifold with a minimal effect on fuel flow rate through the orifice.

Abstract: A hollow impregnation ring for coating fibers with a binder, the ring having a slot thru which the binder flows onto the fibers. The pressure of said binder within said ring controlling a seal and the flow of said binder from said slot.
