    摘要: A sensor element for use in a backing sensor to monitor a gas turbine shaft. The sensor includes an oscillator circuit (30) having an oscillator and a resonance circuit (42), and a frequency detector (31) for monitoring the frequency of the ossilation circuit. Abnormal movement of the shaft cuts the circuit in the sensor along a cutting line (15). The cutting of the sensor changes the capacitance and/or inductance of the resonance circuit and thereby changes the frequency of oscillation.

    摘要: A thermally actuated venting system (12) includes a thermally actuated vent (46) for opening a vent outlet (48) in a gas turbine engine (10) associated compartment (11) with a passive thermal actuator (54) located in the compartment (11) based on a temperature of the compartment (11). Outlet (48) may be located at or near a top (50) of a core engine compartment (13), a fan compartment (11), or a pylon compartment (21). Actuator (54) may be operably connected to a hinged door (52) of vent (46) for opening outlet (48). Actuator (54) may be actuated by a phase change material (110) disposed in a chamber (94) and having a liquid state below a predetermined actuation temperature and a gaseous state above the predetermined actuation temperature. Actuator (54) may include a thermal fuse (120) for closing door (52) during a fire. Thermal fuse (120) may include at least a portion of piston rod (98) or a cylinder wall (116) of actuator (54) being made of a fuse material having a melting point substantially above the predetermined actuation temperature.
