thrust magnitude 中文意思是什麼
thrust magnitude
解釋
推力值-
A test device was designed which tested the properties of thrust according the theory of electromagnetism scale. using the hall - effect sensor to measure the scale displacement that could be converted the magnitude of the thrust
根據電磁天平的原理設計了一套微推力測試裝置，利用霍耳傳感器來測量推力產生的位移，進而通過計算轉換為推力器的推力大小。 -
Calculating result showed : the thrust changing caused by the magnitude of at / ac was more larger than that both of the pressure index : " n " and of the chamber diameter, and the best thrust could be get when at / ac < 0. 3
由數值計算可知， at ac的大小變化所引起的推力變化比壓力指數n和藥室直徑的變化引起的變化大得多，而且當at ac 0 . 3時，可以得到最佳的推力效果。 -
It is shown that when the exit area of secondary nozzle and the fuel / oxidizer ratio is fixed, the increase of mass flow rate of secondary flow lead to the decrease of velocity of mixed flow, and increase of total mass flow rate. the synthetical result of these two phenomenon cause the increase of thrust of rocket ejector, but the increasing magnitude is relatively small, indicating that these is no necessary to claim large bypass ratio in rocket ejector design. in the comparison between two configurations, the typical one has better performance, indicating the importance of pressure ratio
結果表明：在固定二次噴管出口面積和氧燃比的條件下，二次流（引射空氣流）流量的增加引起混合氣體出口速度的下降和總流量的增加，二者綜合作用使發動機推力增加，但增幅不大，表明在設計發動機結構和工作參數時，不必過分追求大的引射系數；兩種結構的性能對比分析表明了增壓比對引射火箭性能的提高具有重要意義；對引射火箭的熱力循環分析同樣表明，增壓比對于提高發動機性能非常關鍵。 -
In the vector control, both the no - load thrust and the thrust with the different current are calculated, and the end effect influenced by the current magnitude is analyzed
在矢量控制運行下，分別計算了電機在空載時和在通以不同電流時的由端部效應引起的波動推力，並且分析了電流大小對端部效應的影響。
