摘要: A surface cooler comprises a plate-like layer and a plurality of spaced-apart fins extending substantially perpendicular from an uppermost layer of the plate-like layer. The plurality of fins defining a plurality of air flow paths. The plurality of spaced-apart fins are configured to augment heat transfer of the surface cooler by increasing the turbulence levels of a fluid flowing through the airflow paths by promoting increased mixing with a resulting increase in the heat transfer coefficient of the surface cooler. A method of forming the surface cooler and an engine including the surface cooler.

摘要: A gas turbine group comprises a device, arranged in a suction-intake duct, for cooling a suction-intake airflow. The device is, for example, a device for injecting a liquid mass flow. The cooling device is activated automatically when a first limit temperature of the ambient air is overshot and is deactivated automatically when a second limit temperature is undershot. Stability of the automatic algorithm can be improved in that the second limit temperature can lie by a specific amount below the first limit temperature. In one embodiment, the limit temperatures are predetermined as a function of the position of an adjustable initial guide blade cascade.

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