According to the air trajectory of every rocket-assisted torpedo part, we establish an equation group of air vertical motion, improve the in-air trajectory model, and simulatively calculate the polynomials of firing distance and flight time,and firing distance and shut down time. Making use of the polynomials, we calculate the cooperative time of formation salvo of torpedoes, and determine command ways for different situations. The result may facilitate the research of operational application of rocket-assisted torpedo.

To improve the stability of Arcjet discharge plasma in low current and high voltage mode, research on the demand of output characteristics of Arcjet Power Conditioning Unit was conducted. In this paper, based on PWM invertors and current mode control, using MOSFET as the main power device, an Arcjet Power Conditioning Unit was developed. Through adding a closed loop feedback circuit of output voltage, it can make the output characteristics of PCU be positive resistance to ensure the stability of Arcjet discharge plasma. The experiment indicates that this PCU can make Arcjet engine work at high voltage mode (100 V, 10 A) and ensure the stability of arcjet discharge plasma. Finally, it provides the experimental data of Arcjet when working.
