An optical particulate detection system for an aircraft is provided. The optical particulate detection system includes an optical particulate detector and a controller. The optical particulate detector includes at least two optical sources and at least one optical sensor distributed in series with respect to a flow path of a component surface of the aircraft. The controller is configured to interface with the optical particulate detector, monitor the at least one optical sensor, and characterize one or more particles of foreign object debris based on a pulse width and two or more scattering ratios determined with respect to light emitted from the at least two optical sources.

Optical particulate detection for an aircraft

A multi-angle multi-wave array may comprise a first set of sensing elements, a second set of sensing elements, and a third set of sensing elements wherein the first set of sensing elements, the second set of sensing elements, and the third set of sensing elements are collectively configured to detect and discriminate between categories of foreign object debris including solid objects and particulates including silicate sand, water vapor, dust, volcanic ash, and smoke.

A pressure sensing film includes first and second films. The first and second films are configured to form an optical cavity therebetween. A flexible transparent film is arranged in the optical cavity. The flexible transparent film is compressible in response to a pressure change in air adjacent the pressure sensing film. A pressure sensing device and a method of sensing pressure adjacent a surface are also disclosed.

A method of operating a multi-angle, multi-wave array may comprise, emitting a first light at a blue wavelength, emitting a second light at an infrared wavelength, emitting a third light at an ultraviolet wavelength, and detecting a scattered light from each of the first light, the second light, and the third light at a plurality of light sensing devices wherein the detection of scattered light is determinative between categories of foreign object debris including solid objects and particulates including silicate sand, water vapor, dust, volcanic ash, sea-salt aerosol, and smoke.

Systems and methods for particulate ingestion sensing in gas turbine engines

A method of applying a coating system to a substrate includes applying a first layer of a high hardness and high modulus of elasticity with an added metal to the substrate, applying a second layer of the high hardness and high modulus of elasticity in combination with the added metal to the first layer. A percent by volume of the added metal in the second layer is lower than the percent by volume of the added metal in the first layer. The method also includes applying two or more intermediate layers formed from an applied mixture of the high hardness, high modulus of elasticity material and a metal material between the first layer and the second layer.

Method of forming a multilayered coating for improved erosion resistance

An erosion resistant coating for a substrate includes two or more coating layers affixed to the substrate having an increasing modulus of elasticity and hardness from an innermost layer of the coating adjacent to the substrate to an outermost layer of the coating furthest from the substrate. A method of applying a coating system to a substrate includes applying a first layer of a high hardness and high modulus of elasticity material combined with an added metal to the substrate. A second layer of the high hardness and high modulus of elasticity material combined with the added metal is applied to the first layer, resulting in a coating system wherein the second layer has a modulus of elasticity and hardness greater than the modulus of elasticity and hardness of the first layer.
