摘要:針對小型渦噴發(fā)動機在空中停車故障,結(jié)合發(fā)動機控制原理及對遙測數(shù)據(jù)進行仔細分析,確認發(fā)動機轉(zhuǎn)速采集信道出現(xiàn)問題導(dǎo)致發(fā)動機控制系統(tǒng)進入邊界控制,而邊界條件設(shè)置不合理導(dǎo)致發(fā)動機工作在超速超溫狀態(tài),最終失效。通過采取增加轉(zhuǎn)速采集備份信道、改進ECU控制保護算法、修改ECU檔位油門限幅等措施有效地解決了此類故障,提高了發(fā)動機工作的可靠性。 Towards the minitype turbojet engine's malfunction of staying still in the air, and from the engine control principle and the typical analysis of the telemetering datas, we make sure that the engine speed acquisition channel doesn't work well, thus making the engine control system runs in the state of boundary controling , while the unproper settings of boundary conditions leads to a state of overspeed and overheat for the function of engine, which results in the failure of the engine in the end. We effectively promote the reliability of engine functioning by solving these problems through enlarging the amount of engine speed acquisition channel, improving the ECU control protection algorithm, and modifying the ECU gear accelerator limiter as well as other measures . ![]() (每個字母都自己敲的,還反復(fù)修改。。。希望對你有幫助) |
