Plume impingement heating to international space station (ISS)

摘要

Engineering models have been developed to predict plume impingement heating environments to components of the International Space Station (ISS) during its buildup and operation. The objective of the study was to use the Orbiter Project-approved Reaction Control System (RCS) plume model with impingement heating (RPM 3.0) in the mid to far-field and the Reactign and Multi-Phase (RAMP) plume model with impingement heating (PLIMP) in the near-field. Plume heating was generated from RPM 3.0 for the Orbiter PRCS single and dual scarfed jets during approach to various ISS components (solar panels, radiator, Pressurized Mating Adapter (PMA), Russian hardware, etc.). Heating environments from ISS Russian Attitude Control System (ACS) jets were predicted from PLIMP to the Functionali Gruzvoi Blok (FGB) grapple fixture for various fixture locations. Orbiter PRCS plume heating results are presented as a function of distance between docking ports, distance along component, solar panel feathering angle, and position in approach cone. The heating environments from both orbiter proximity and ISS station-keeping operations have been transmitted to ISS thermal designers to determine temperature response, functionality, and survivability of the respective structures.
