    Abstract: A tangential on-board injector (TOBI) for a gas turbine engine is provided. The TOBI includes a body having an entrance and an exit, the body having an outer curved wall and defining an air passageway between the entrance and the exit and a purge cavity configured on an exterior surface of the body with a purge cavity entry fluidly connecting the air passageway to the purge cavity. The purge cavity is configured such that particles in an airflow through the passageway will enter the purge cavity.

    Abstract: A combustor may include a combustor shell, a particle collection panel, and a combustor panel. The combustor shell may define a plurality of first impingement holes, the particle collection panel may include a plurality of particle collection chambers and may define a plurality of second impingement holes, and the combustor panel may define a plurality of effusion holes. The particle collection panel may be disposed inward of the combustor shell and the combustor panel may be disposed inward of the particle collection panel. Each particle collection chamber may have a closed inward end and an opening defined in an outward end. The particle collection chambers may be configured to entrap particulates.

    Abstract: A turbine section according to an example of the present disclosure includes, among other things, a component including a coating on a substrate, and at least one sensor positioned a distance from the component, the at least one sensor configured to detect radiation emitted from at least one localized region of the coating at a first wavelength and configured to detect radiation emitted from the substrate corresponding to the at least one localized region at a second, different wavelength. The first wavelength and the second wavelength are utilized to determine a heat flux relating to the at least one localized region. A method of measuring a gas turbine engine component is also disclosed.
