| Abstract: | To the CAST968 small satellite plate,based on the HY-1 small satellite,the requirement of its orbit transfer mission is indicated.As contrasted with the monopropellant hydrazine thruster which was used in the HY-1,the PPT applied characters are referred to.According to shape and structural parameters of the HY-1,the number and the work scheme of orbit transfer PPT are designed roughly.The PPT orbit transfer methods are demonstrated and analyzed according to the PPT state-of-the-art and its propulsive abilit... |
