A spacecraft with a passive thermal control system utilizes various thermal control materials to maintain temperatures within safe operating limits.
Studies on the degradation in the optical properties (solar absorptance and infrared emittance) of some important thermal control materials exposed to simulated radiative geostationary space environment are discussed.
Spacecraft thermal control materials (TCMs) play a vital role in the entire service life of a spacecraft [NASA Preferred Reliability Practices: Spacecraft Thermal Control Coatings Design and Application (Practice No. PD-ED-1239 PD-ED-1239 PD-ED-1239
The thermal control materials investigated herein include different kind of second-surface mirrors, white anodizing, white paints, black paints, multilayer insulation materials, varnish coated aluminized polyimide, germanium coated polyimide, polyether ether ketone (PEEK) and poly tetra fluoro ethylene (PTFE).
This paper describes the effect of synergistic radiation on some of the important thermal control materials to verify the assumptions of beginning-of-life (BOL) and end-of-life (EOL) properties.
In this paper the thermal control, via pyroelectric materials, is presented.
Controlling thermal interaction through the building envelope is important for maintaining indoor thermal comfort and therefore it requires proper selection of thermal control strategies and building materials.
The present results give insights into developing higher performance V2VI3 polycrystalline materials through thermal control the donor-like effect.
When the concentration of the silicate is 10 g/L and the current density is 10 A/dm2, the best coating was obtained with the solar absorbance of 0.39, hemispherical emissivity of 0.92, and the balance temperature of 318 K, which presents a promising application prospect in the thermal control system of Ti alloys materials.
Technical challenges include the balloon materials, fabrication, power, thermal control, attitude control, telecommunications, data storage and international overflight.
The book also discusses main energy storage options for thermal management practices in photovoltaics and phase change material applications that aim passive thermal control.
