The measurements of the separated vortex field and forces for drag plate show that the nose up pitching moment is produced due to the large induced downwash angle from the separated vortices of drag plate at the tail.
在ＮＨ－２風(fēng)洞中對某機放減速板產(chǎn)生較大抬頭力矩的機理進行了研究，通過減速板分離渦場的測量和測力試驗表明，抬頭力矩主要是由減速板分離渦在平尾處產(chǎn)生較大的誘導(dǎo)下洗角所致，誘導(dǎo)下洗角沿機身軸線向后逐漸減小，減速板前移可以消除抬頭力矩。
