摘要： A method of lasing a filler wire to weld a first workpiece to a second workpiece comprising first and second materials, respectively, includes positioning a tip of the filler wire above an opening defined by the workpieces. The tip extends over a width of the opening and over a portion of each of the workpieces. The filler wire is preheated and melted by directing a laser beam at the tip. The laser beam is advanced along a length of the opening with the tip positioned under the laser beam to form a high aspect ratio weld between the workpieces. The high aspect ratio weld has an aspect ratio of at least about two. The energy and time required for the laser beam to melt the filler wire is reduced as the filler wire is preheated.

摘要： The present invention includes an intercooled cycle gas turbine. The intercooled cycle gas turbine is supercharged to improve performance. Pereformance is defined in terms of thermal efficiency and mass specific power, the turbine defining a cycle with a peak cycle pressure and a peak cycle temperature. The turbine includes an intercooler for intercooling the turbine, wherein placement of the intercooler within the cycle divides the cycle into a first compression stage and a second compression stage. The intercooler placement r=1/2 ln P.sub.super /ln(P.sub.peak /P.sub.super). The first compression stage and the second compression stage have an unequal pressure ratio.

摘要： A gas turbine engine fuel control system has a three-dimensional cam which is positioned by sensed values of engine compressor inlet and outlet pressures. The cam has two profiles which respectively indicate a desired ratio of the compressor pressures and a desired fuel flow. Interlinked cam followers engage the respective cam profiles and are also responsive to a device for setting a desired engine thrust. The cam follower linkage positions a variable metering device for the engine fuel supply.

摘要： Rockets, rocket motors, methods of controlling a rocket and methods of evaluating a rocket design are disclosed. In some embodiments, a method of controlling a rocket may include measuring a combustion chamber pressure, calculating a logarithm of the measured combustion chamber pressure, and computing the difference between the logarithm of the measured combustion chamber pressure and the logarithm of a reference combustion chamber pressure value to generate an error signal. The method may further include filtering the error signal to generate a compensated signal in the logarithm domain, and exponentiating of the compensated signal in the logarithm domain to provide a compensated signal in the physical domain.
