DLR operates the High Vacuum Plume Test Facility Göttingen – Electric Thrusters (STG-ET). This electric propulsion test facility has now accumulated several years of EP-thruster testing experience. Special features tailored to electric space propulsion testing like a large vacuum chamber mounted on a low vibration foundation, a beam dump target with low sputtering, and a performant pumping system characterize this facility. The vacuum chamber is 12.2m long and has a diameter of 5m. With respect to accurate thruster testing, the design focus is on accurate thrust measurement, plume diagnostics, and plume interaction with spacecraft components. Electric propulsion thrusters have to run for thousands of hours, and with this the facility is prepared for long-term experiments. This paper gives an overview of the facility, and shows some details of the vacuum chamber, pumping system, diagnostics, and experiences with these components.

Locomotive Diesel

In order to determine the fuel consumption during operation of locomotive it is necessary to work out the characteristics of fuel consumption vs. power produced by propulsion system. These characteristics can be obtained during tests in a diagnostic stand equipped with water rheostat, which allows to simulate any load on the main generator. Another method depends on utilization data from monitoring system of the propulsion system, obtained during regular operation of the locomotive. The main disadvantage of this method is lack of long-term constant loads, which is caused by frequently changing operating conditions. This has a major impact on the measuring error, which can be minimized by suitable utilization of a large number of measurements. Practical remarks of those methods usage have been presented in this paper.
