The pilot project of a manufacturing execution system implementation specially developed by Siemens AG for discrete manufacture has come closer to its basic operating stage by breadboard model delivery on Proton-PM (Perm Motors) Public Corporation, one of the largest enterprises of the space and rocket industry of the Russian Federation.
of SITEK Group, a provider of adaptive operations execution software solutions and advanced planning systems for manufacturing organizations in Russia, Europe and CIS, the main Competence center on MES-systems authorized by Siemens AG and the Russian Proton-PM (Perm Motors) space and rocket industry enterprise performed the next stage of the ongoing project having finished the system engineering by successful delivery of a test example on MCIS (Motion Control Information System) breadboard model on December 23rd , 2010.
For its day, the MSJ was a very advanced piece of equipment, and the breadboard model functioned well during flight tests.
To investigate the variation in output power level and phase noise property of the conventional push-push FET DRO by adding an identical DR at the drain port, the circuit topology described in references 2 through 5 has been chosen as a breadboard model. The push-push FET DRO circuit model has been designed to enhance the second harmonic (20 GHz) of the 10 GHz fundamental frequency of the oscillator.
In addition, the operation of a breadboard model of the intended power supply/conditioning systems (including an actual, real-size high-voltage transformer and high-voltage output assembly) was demonstrated by fully energizing a conventional "minitube."
The demonstrated breadboard model driving a mini-tube yielded overall efficiencies in excess of 90% while achieving excellent static and dynamic load and line regulations.
