摘要： A cooling fluid air injection system for use in a gas turbine engine includes at an external cooling fluid source, at least one rotor cooling pipe, which is used to inject cooling fluid from the source into a rotor chamber, a piping system that provides fluid communication between the source and the rotor cooling pipe(s), a blower system for conveying the cooling fluid through the piping system and the rotor cooling pipe(s) into the rotor chamber, and a valve system. The valve system is closed during full load engine operation to prevent cooling fluid from the source from passing through the piping system, and open during less than full load engine operation to allow cooling fluid from the source to pass through the piping system.

摘要： A fuel injector (36) for alternate fuels (26A, 26B) with different energy densities. Vanes (47B) extend radially from a fuel delivery tube structure (20B) with first and second fuel supply channels (19A, 19B). Each vane has first and second radial passages (21A, 21B) communicating with the respective fuel supply channels, and first and second sets of apertures (23A, 23B). The first fuel supply channel, first radial passage, and first apertures form a first fuel delivery pathway providing a first fuel flow rate at a given fuel delivery pathway backpressure that is essentially common to both sets of fuel delivery pathway apertures. The second fuel supply channel, second radial passage, and second apertures form a second fuel delivery pathway providing a second fuel flow rate that may be at least 1 about twice the first fuel flow rate at the given fuel delivery pathway backpressure.

摘要： One embodiment disclosed relates to a method of obtaining status information from user threads of a target process. A system call is performed from a querying process. The system call creates a kernel debug thread in a kernel entity of the target process. The kernel debug thread further creates a user status thread in a user entity of the target process. The method may be used to obtain the status information without stopping the target process. Another embodiment disclosed relates to an operating system with capability to obtain status information from user threads of a target process. The operating system includes at least the following first and second system calls. The first system call is configured to create a kernel debug thread in a kernel entity of the target process. The second system call is configured to awake the kernel debug thread and pass information to the kernel debug thread.
