Electro-Hydraulic Control Systems

Electro-Hydraulic Drives of Remote Control of Launch System

Remote control drives are designed to provide movement control of support trusses (ST), pilot devices (PD), low launch umbilical tower (LLUT), and top launch umbilical tower (TLUT) of launch system.

The drives are designed:

  • to bring all the four of the supporting trusses together up to closing, to interlock upper force ring, to elevate TLUT, and to keep ST and TLUT in operating position;
  • to put two LLUT and four PD to operation position and retrace them into initial position.

The drives operate in maritime tropical climate:

  • at ambient temperature from 23 to 34 ºС;
  • under air humidity up to 97%;
  • in foggy and dusty environment;
  • after vibration and acoustic impact of gas jets of carrier rocket engines during its start and initial flight path.

Power supply of electro hydraulic drive for remote control of launch pad and TLUT hydraulic drive:

  • Current: 3-phase AC
  • Voltage: (380 ± 19) V
  • Frequency: (50 ± 0.4) Hz
