Design analysis and containment canister life prediction for a Brayton engine solar receiver for Space Station
- Allied-Signal Aerospace Systems and Equipment, Torrance, CA (United States)
A study has been conducted on the design and development of a solar receiver to be used for electrical power production for Space Station. The receiver incorporates integral thermal storage, using a eutectic mixture of LiF and CaF[sub 2] as a solid-to-liquid phase-change material (PCM). The design comprises a cylindrical receiver cavity. The walls of the cavity are lined with a series of working fluid tubes running the length of the cavity. The PCM is enclosed in individual, sealed metallic containment canisters which are stacked and brazed to the tubes. The compartmentalization of the PCM localizes void formation upon freezing. An additional attribute of compartmentalization is that a containment canister failure affects only that canister; the receiver continues to operate with only a minute loss of capacity. Nevertheless, a considerable effort has been expended to ensure that the containment canisters will survive a 30-year life. A detailed analytical procedure was developed to evaluate the canister creep strain accumulated in 30 years. This accumulated creep strain, which is in the range of 0.03 to 0.79 percent, compares favorably with the preliminary value of four percent for the canister material allowable 30-year creep rupture ductility.
