Novel Approach for Robust Control of Axial Piston Pump

Mathematics
The article is devoted to designing novel multivariable robust μ-control of an open-circuit axial piston pump. In contrast with classical solutions of displacement volume control, in our case, the hydro-mechanical controller (by pressure, flow rate, or ...

Axial piston pumps, new trends and development

, 2012
International audience ; Efficiency improvement is a key issue in any machine. The fluid power industry relies on volumetric pumps which need to pump high pressure fluid to a set of actuators located at different positions in a given device; the higher the pressure, the smaller the actuators need to be, therefore allowing to reduce the weight of the ...

The performance and application of high speed long life LH2 hybrid bearings for reusable rocket engine turbomachinery [PDF]

Data are presented for two different experimental programs which were conducted to investigate the characteristics of a hybrid (hydrostatic/ball) bearing operating in liquid hydrogen. The same bearing design was used in both programs.
