摘要： A starting system and method for a gas turbine engine checks to determine whether ignition has occurred in a light off window. If such ignition has not occurred, a starter coupled to the gas turbine engine is deactuated to allow deceleration through the light off window while still attempting to ignite gases in the combustor. By providing an extra interval of time to achieve ignition, start reliability is enhanced.

摘要： Cavitation in axial piston motors (20) caused to act as a pump by an aiding load (28), and the related difficulty of loss of hydrostatic film (52), and tipping or hammering of motor slippers (64), can be reduced by a method which includes the step of recirculating hydraulic fluid from the supply port (18) of the motor (20) to the return port (30) of the motor (20) upon the occurrence of an aiding load (28).

摘要： A sleeved boiler-reactor provides enhanced nucleate boiling and reduced risk of film-boiling within boiling tubes of the boiler-reactor, in the same manner as prior boiler-reactors of seam-welded construction, without the high fabrication cost incident with seam-welding, through the use of a closely wound helical shaped boiling tube structure (30, 52) constrained by lugs (66, 68) against a sleeve portion (14, 16) of the casing of the boiler-reactor.

摘要： A circuit to discriminate the source of harmonic distortion of the output voltage comprises voltage sensors (28, 30) coupled to the output terminals of a source of electric power (16) and to a point of regulation (24) remote from the source for sensing the output voltage waveform present at each of these locations; means (32, 34) coupled to the voltage sensors (28, 30) for calculating the percentage total harmonic content of each of the sensed waveforms, and means (36) for comparing them to determine the source of distortion; means (42) coupled to the voltage sensors (28, 30) for calculating the actual voltage difference between the two sensed voltages, and means (46) for sensing the current flowing in the feeders (18a-c) which is compared with a profile of the normal voltage drop versus connected load (48) to generate an expected voltage drop; and a protection logic circuitry (40).

摘要： The turbine engine (10) includes a turbine wheel (12) coupled to a compressor (14), a nozzle (16), and an annular combustor (18). The combustor (18) receives fuel from a source and air from the compressor (14) and combusts fuel and air in the combustion space to generate the gases of combustion. The turbine engine (10) also includes at least one air blast fuel injector (26) disposed in the annular outer wall (20) of the combustor (18) for injecting atomized fuel generally tangentially of the outer wall (20) outwardly of a flame zone (28) within the combustion space. The turbine engine (10) utilizes air film strips (36, 38, 40) and/or holes (20b, 22b, 24b) for cooling the combustor (18) with an air film on an inwardly facing surface of one or more of the walls (20, 22, 24) defining the combustor (18) while at the same time avoiding the filming of air onto the outer wall (20) radially outwardly of and generally axially coextensive with the flame zone (28).

摘要： An improved axial-piston energy converting device is provided by utilizing a thin ceramic wear plate insert, having a typical thickness of only about .005 to .040 inches in thickness, as a cam surface secured by atmospheric pressure to an underlying support surface of a steel cam plate support structure. Attachment of the wear plate to the cam plate supporting surface is accomplished by polishing both a supporting surface of the cam plate, and a mating surface of the wear plate to a very smooth finish, and wiping a thin film of a fluid such as oil onto one of the polished surfaces prior to placing the wear plate onto the supporting surface. The highly polished surface, together with the light film of oil, results in a joint that is essentially air tight. Atmospheric pressure acting on the cam surface of the wear plate serves to hold the wear plate tightly in place on the support surface in the same manner that a pair of Johansson blocks are held together if their highly polished surfaces are mated.
