With the demands of designing the large - scale cargo airplane , in this thesis , many technical materials about the mechanisms of current wing flap types , of foreign transport airplanes are carefully studied at first , and the mechanical composition of three - gaps - fowler - flap is summarized technically about its major basic components , prime mechanism ( track ) , driving device , sub - flaps mechanism and the sub - flaps sequential control system 在本文中,針對大型運(yùn)輸機(jī)機(jī)翼設(shè)計(jì)的需求,首先對幾種國外運(yùn)輸機(jī)襟翼運(yùn)動(dòng)機(jī)構(gòu)的資料進(jìn)行仔細(xì)研究,對三縫富勒襟翼運(yùn)動(dòng)機(jī)構(gòu)的組成進(jìn)行了分析,總結(jié)歸納出了三縫富勒襟翼運(yùn)動(dòng)機(jī)構(gòu)的3個(gè)基本組成部分:主機(jī)構(gòu)(軌道) ,驅(qū)動(dòng)機(jī)構(gòu),子襟翼機(jī)構(gòu)及子襟翼運(yùn)動(dòng)控制機(jī)構(gòu)。
