A method of making a ceramic matrix composite component includes forming a ceramic matrix composite component by infiltrating an array of ceramic-based reinforcements with a ceramic-based matrix, applying filler particles to a surface of the ceramic matrix composite component such that the filler particles fill in gaps between adjacent ones of the ceramic-based reinforcements, and infiltrating the filler particles with a filler matrix. A ceramic matrix composite component is also disclosed.

A power-receiving-module-type telemeter transmitter of a telemeter measuring system that is provided in a rotor and that performs communication using power received from a power transmitting antenna formed in an arc shape on a stator side, includes: a plurality of power receiving modules disposed in the rotor at intervals in a circumferential direction; an OR circuit that outputs a highest voltage among voltages input from the plurality of power receiving modules; a sensor that measures a state of a monitoring target and that outputs measurement data indicating the state; and a transmitting unit that is driven by the voltage input from the OR circuit as a power source and that transmits a radio signal including the measurement data of the sensor.

Disclosed is an automatic throttle arrangement utilizing a servo which receives commands from a controller on an aircraft and responsively rotates a mechanical device that is linked by a cable arrangement with the aircraft’s throttle lever enabling automated throttle control. The mechanical device can be fixed to the throttle lever assembly using rivets designed to fail in case the servo/cable arrangement jams. This leaves the lever able to continue manual function.

A sign detection device includes: a plurality of sensors disposed at a plurality of positions on a detection target object and configured to measure physical quantities at each position; a data acquisition unit for acquiring time-series fluctuation data of the physical quantities from the plurality of sensors; a calculation unit for calculating, from the time-series fluctuation data, a parameter indicating a correlation between the physical quantities at arbitrary two positions among the plurality of positions; and a detection unit for detecting a sign of sudden change in vibration of the detection object based on the parameter.

The invention relates to an assembly for a turbomachine with a longitudinal axis comprising a first annular wall (24), panels (38) being arranged around the longitudinal axis (A) and extending radially opposite said first annular wall (24) so as to form a flow surface for a flow of air, each panel (38) being secured to the first annular wall (24) by at least one fixing member (72) passing through an orifice in the panel (38) and secured to the first annular wall (24) by means of a sleeve and a stud forming a spacer.

A liner for a combustor in a gas turbine engine. The liner includes a liner body having a cold side and a hot side. The liner includes a dilution passage having a concatenated geometry extending through the liner body. The concatenated geometry has a plurality of discrete dilution holes, an annular slot, and a fence concatenated with the plurality of discrete dilution holes. The dilution passage is configured (i) to integrate a first dilution air flow flowing through the plurality of discrete dilution holes from the cold side to the hot side and a second dilution air flow flowing through the annular slot from the cold side to the hot side into an integrated dilution air flow, and (ii) to inject the integrated dilution air flow into a core primary combustion zone of the combustor to attain a predetermined combustion state of the combustor.
