(Main)Space engineering - Two-phase heat transport equipment
Space engineering - Two-phase heat transport equipment
This standard defines requirements for two-phase heat transportation equipment (TPHTE), for use in spacecraft thermal control.
This standard is applicable to new hardware qualification activities.
Requirements for mechanical pump driven loops (MPDL) are not included in the present version of this Standard.
This standard includes definitions, requirements and DRDs from ECSS-E-ST-10-02, ECSS-E-ST-10-03, and ECSS-E-ST-10-06 applicable to TPHTE qualification. Therefore, these three standards are not applicable to the qualification of TPHTE.
This standard also includes definitions and part of the requirements of ECSS-E-ST-32-02 applicable to TPHTE qualification.
ECSS-E-ST-32-02 is therefore applicable to the qualification of TPHTE.
This standard does not include requirements for acceptance of TPHTE.
This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

Vesoljska tehnika - Oprema za dvofazni toplotni transport
Ta standard določa zahteve za opremo za dvofazni toplotni transport (TPHTE) za uporabo pri toplotnem nadzoru vesoljskih plovil. Ta standard se uporablja za dejavnosti, povezane s kvalifikacijo nove strojne opreme. Zahteve za zanke s pogonom prek mehanskih črpalk (MPDL) niso vključene v trenutno različico tega standarda. Ta standard vključuje definicije, zahteve in dokumente z definicijami zahtev iz standardov ECSS-E-ST-10-02, ECSS-E-ST-10-03 in ECSS-E-ST-10-06, ki se uporabljajo za kvalifikacijo TPHTE. Zato se ti trije standardi ne uporabljajo za kvalifikacijo TPHTE. Ta standard vključuje tudi definicije in del zahtev standarda ECSS-E-ST-32-02, ki se uporabljajo za kvalifikacijo TPHTE. ECSS-E-ST-32-02 se zato uporablja za kvalifikacijo TPHTE. Ta standard ne vključuje zahtev za sprejetje TPHTE. Ta standard se lahko prilagodi posameznim lastnostim in omejitvam vesoljskega projekta v skladu s standardom ECSS-S-ST-00.

Introduction
This Standard replaces ESA PSS-49, Issue 2 “Heat pipe qualification
requirements”, written in 1983, when the need for heat pipes in several ESA
projects had been identified. At that time a number of European development
activities were initiated to provide qualified heat pipes for these programmes,
which culminated in a
