Scm control system of pulse plasma arc welding 脈沖等離子弧焊接的單片機(jī)控制系統(tǒng)
In the summarize of plasma propulsion and discharging in water and exploding wires phenomenon , this paper combines technology in three fields hereinbefore . an experimental pulse plasma propeller model has been designed 本文在對等離子體推進(jìn)、液中放電和爆炸絲現(xiàn)象綜述的基礎(chǔ)上,將這三個領(lǐng)域的技術(shù)結(jié)合在一起,研制出實(shí)驗(yàn)用水中脈沖等離子體推進(jìn)模型。
The main characteristic of pulse plasma propulsion in water is great propulsion in moment , whose average propulsion is smaller . so it may be useful for side face propulsion of ships in static state as the assistant propulsion 水中脈沖等離子體推進(jìn)的主要特點(diǎn)是瞬間推力大,但由于它所產(chǎn)生的平均推力小,更適合用作助推力,可實(shí)現(xiàn)船舶的定向和準(zhǔn)確???。
With advantages of simple and reliable in structure , high isp and easy control over a wide range of thrust , pulsed plasma thruster ( ppt ) is very suitable for micro - satellite ' s orbit control and high precision attitude control 脈沖等離子體推力器( ppt )具有結(jié)構(gòu)簡單可靠,比沖高,推力在較大范圍可控的特點(diǎn),適合用于微、小衛(wèi)星軌道控制和小衛(wèi)星高精度姿態(tài)控制,其研究和應(yīng)用得到了重視。
A coaxial micro - pulsed plasma thruster ( micro - ppt ) improved from the standard pulsed plasma thruster ( ppt ) is drawing attention by its advanced properties of low volume , high isp , high efficiency and stabilization . a coaxial micro - ppt using solid inert propellant teflon has been made in center for space science and applied research ( cssar ) , chinese academy of sciences 針對應(yīng)用于微小衛(wèi)星的電推進(jìn)技術(shù),各國爭相開展相關(guān)的研究,其中一種經(jīng)由傳統(tǒng)的平行板電極ppt改進(jìn)的同軸型脈沖等離子體微推進(jìn)器(以下簡稱同軸型微ppt )由于其尺寸小、比沖高、效率高、工作可靠等特點(diǎn)尤其受到關(guān)注。
