Base Application

A lithium heat pipe cooled modular fast reactor (HPCMR) power system concept has been developed for manned lunar base application. The system is designed to use the static thermoelectric conversion module to produce over 100kW electricity for up to ten years. Waste heat is rejected by potassium heat pipe radiator. This system has advantages of low mass, long lifetime, no pumped liquid coolant, and no single point of failure. Main parameters of the system are also given in this paper.

The Galerkin Method

For the fan structure, 8-node isoparametric quadrilateral elements are used to discretize the structure based on the fan blade shape while 20-node isoparametric hexahedron elements are used to discretize the surrounding air of the fan blade. The intensity of pressure at an arbitrary point in the surrounding air can be solved by the Galerkin method when the boundary condition is considered. The Wilson-Θ method with good stability is used to solve the air-structure coupling equations. The calculated natural modes and the tested natural modes are compared. The mode method is used to calculate and analyze the fan blade dynamic characteristics in order to study the air-structure coupling.
