Space Engineering. Thermal design handbook. Louvers | Status: Current

1 Scope Thermal louvers are thermal control surfaces whose radiation characteristics can be varied in order to maintain the correct operating temperature of a component subject to cyclical changes in the amount of heat that it absorbs or generates. The design and construction of louvers for space systems are described in this Part 12 and a clause is also dedicated to providing details on existing systems. The Thermal design handbook is published in 16 Parts TR 17603‑31‑01 Thermal design handbook – Part 1: View factors TR 17603‑31‑02 Thermal design handbook – Part 2: Holes, Grooves and Cavities TR 17603‑31‑03 Thermal design handbook – Part 3: Spacecraft Surface Temperature TR 17603‑31‑04 Thermal design handbook – Part 4: Conductive Heat Transfer TR 17603‑31‑05 Thermal design handbook – Part 5: Structural Materials: Metallic and Composite TR 17603‑31‑06 Thermal design handbook – Part 6: Thermal Control Surfaces TR 17603‑31‑07 Thermal design handbook – Part 7: Insulations TR 17603‑31‑08 Thermal design handbook – Part 8: Heat Pipes TR 17603‑31‑09 Thermal design handbook – Part 9: Radiators TR 17603‑31‑10 Thermal design handbook – Part 10: Phase– Change Capacitors TR 17603‑31‑11 Thermal design handbook – Part 11: Electrical Heating TR 17603‑31‑12 Thermal design handbook – Part 12: Louvers TR 17603‑31‑13 Thermal design handbook – Part 13: Fluid Loops TR 17603‑31‑14 Thermal design handbook – Part 14: Cryogenic Cooling TR 17603‑31‑15 Thermal design handbook – Part 15: Existing Satellites TR 17603‑31‑16 Thermal design handbook – Part 16: Thermal Protection System
