A contamination sensor for a gas turbine engine is disclosed herein. The contamination sensor is made of a selected composition of material and includes a base alloy, an alloy for improving oxide formation, and at least one element from the transition metal group. The composition of the contamination sensor can be adjusted to react with specific contaminants at specific temperature ranges.

A diffuser for use in a gas turbine engine, the diffuser having a first wall, a second wall, and a flow separator. The first and second wall define an annular cavity, with the annular cavity having an inlet. The first and second wall also forming a prediffuser that is proximate the inlet, and a dump region distal the inlet. The flow separator extends from the first wall into the annular cavity.

A particle deflector for a gas turbine engine deters accumulation of particles in cooling passages of nozzle vanes of the engine. The particle deflector is arranged to be disposed around a turbine housing over cooling passages that supply cooling air to nozzle vanes within the housing. The particle deflector includes circumferentially distributed mounting holes for mounting the particle deflector to the turbine housing. The particle deflector also includes circumferentially distributed spacers to space the particle deflector from the housing.

A preswirler of a gas turbine engine includes an outer ring. The outer ring includes an outer flange with a plurality of first holes, and an outer cylindrical portion extending from the outer flange. The preswirler also includes an inner ring. The inner ring includes an inner flange spaced apart from the outer flange. The inner ring also includes an inner cylindrical portion located within the outer cylindrical portion and a back portion extending from the inner flange to the inner cylindrical portion. The inner ring further includes a plurality of second holes.

Preswirler configured for improved sealing

A plug for an inspection hole of a gas turbine engine is disclosed. The plug may have a stem including a first shaft, wherein a first seal is located circumferentially about the first shaft. The plug may have a swivel seal including a second seal spaced from a ball by a second shaft, and the swivel seal may be rotatably connected to the stem by the ball. The ball and the second seal may be fixed to the second shaft.

Inspection hole plug with a ball swivel

A baffle assembly for a housing of a combustor system of a gas turbine engine is provided. The baffle assembly includes a baffle retainer and a baffle. The baffle retainer includes a retainer tube and a collar. The retainer tube is received within a bleed port of the housing. The collar is defined at an upper end of the retainer tube and is configured to rest against the housing. The baffle includes a baffle tube rigidly attached to an inner surface of the retainer tube.
