論文名稱: 具有不同電極夾角的脈衝電漿推進器的優化與性能量測 / Optimization and performance measurements of the pulsed plasma thruster with various electrode angles
中文摘要:
本論文優化並量測採用對稱與非對稱張角電極的脈衝式電漿推進器（PPT）之性能。研究以田口法將三種電極角度的組合縮減為九種配置，以最少實驗次數追求最大衝量與排氣速度，並以三重朗謬爾探針量測電漿性質，推算衝量、排氣速度、電子溫度與電子密度，確定電極角度、放電能量與對稱性對各參數的影響。其中實驗3（電極角度[0;40]、放電能量2 J）表現最突出，衝量為158.55 μN·s、電漿速度39,071 m/s、電子溫度18.48 eV、電子密度4.95×10²⁰ m⁻³。研究已找出各參數的最佳配置，但尚待驗證。
英文摘要:
This thesis optimizes and measures the performance of a pulsed plasma thruster (PPT) with symmetric and asymmetric flared electrode angles. Three electrode angles were studied in nine configurations selected with the Taguchi method, which maximizes impulse bit and exhaust velocity with few runs. A triple Langmuir probe measured plasma properties, from which impulse bit, exhaust velocity, electron temperature, and electron density were derived, and the influence of electrode angle, discharge energy, and symmetry on each was determined. Experiment 3 (electrode angles [0;40], 2 J) stood out, producing an impulse bit of 158.55 μN·s, a plasma velocity of 39,071 m/s, an electron temperature of 18.48 eV, and an electron density of 4.95×10^20 m^-3. The optimal configuration for each parameter was identified but not yet verified.
