ABSTRACT:
An automatic recovery pilot nozzle support system for supporting a pilot nozzle in a fuel injection system of a turbine engine. The support system includes a sleeve extending from an orifice in a support housing, wherein the sleeve has a hollow opening for containing a pilot nozzle. The sleeve may increase the natural frequency of the pilot nozzle above an excitation zone, thereby limiting destructive vibrations. The sleeve may be attached to the support housing with an interference fit. The automatic recovery aspect of the support system enables the sleeve to maintain an interference fit with the support housing such that anytime the sleeve looses contact with the support housing, an insulative film of air forms between the sleeve and the support housing. The insulative film of air causes the temperature of the sleeve to increase, and the sleeve to expand and reform the interference fit with the support housing.
