Thermally actuated venting system for a compartment of an aircraft gas turbine engine |
摘要 |
<p>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.</p> |
