New Aerospace and Defense Study Findings Have Been Reported from Harbin Institute of Technology (Displaced Electric Sail Orbits Design and Transition Trajectory Optimization)

By a News Reporter-Staff News Editor at Defense & Aerospace Week -- Investigators publish new report on Aerospace and Defense. According to news reporting originating in Harbin, People's Republic of China, by VerticalNews journalists, research stated, "Displaced orbits for spacecraft propelled by electric sails are investigated as an alternative to the use of solar sails. The orbital dynamics of electric sails based spacecraft are studied within a spherical coordinate system, which permits finding the solutions of displaced electric sail orbits and optimize transfer trajectory."

The news reporters obtained a quote from the research from the Harbin Institute of Technology, "Transfer trajectories from Earth's orbit to displaced orbit are also studied in an optimal framework, by using genetic algorithm and Gauss pseudospectral method. The initial guesses for the state and control histories used in the Gauss pseudospectral method are interpolated from the best solution of a genetic algorithm."

According to the news reporters, the research concluded: "Numerical simulations show that the electric sail is able to perform the transfer from Earth's orbit to displaced orbit in acceptable time, and the hybrid optimization method has the capability to search the feasible and optimal solution without any initial value guess."
