In this article, using the whole-flow-field general design theory, the air-shock type fixed-wing airplane seeder was explained aft an example.

农用飞机播种机是飞机外挂机具。播种时,种子从播种机出口向地面下落过程中,受飞机流场影响很大,往往改变设计者预定的种子下落轨迹线,从而影响播种精度。我们运用飞机生流场总体设计理论,改进原来常规的设计方法,设计出了FB-85型飞机播种机,经试验证明:应用全流场总体设计理论所设计的飞机播种机,主要性能指标有很大的提高。此理论不但对飞机播种机设计具有指导意义,而且对其他飞机喷洒装置的设计也具有指导意义。本文以定翼飞机气击式播种机为例,讨论了飞机全流场总体设计的问题。
