parachute canopy

基本解釋

As a parachute canopy moves unsteadily through the air, its equations of motion must include the rate of change of momentum of the air in which it is immersed.
當(dāng)降落傘在空氣中作非定常運(yùn)動(dòng)時(shí)，空氣動(dòng)量的變化率必須包括在降落傘的運(yùn)動(dòng)方程中。
The opening process of the circle flat parachute with the differential size and the differential vent position of the canopy by the steady flow wind tunnel were dynamic tested.
在改變傘衣面積和透氣量的情況下，在定常風(fēng)洞中對(duì)小型平面圓形傘的開傘過程進(jìn)行了動(dòng)態(tài)試驗(yàn)，研究了開傘過程中傘衣形狀和傘衣所受載荷之間的動(dòng)態(tài)關(guān)系。
With the landing impact attenuation devices, area of parachute canopy, weight of recovery system and landing impact load could be greatly reduced, In these years, the technologies have been developed.
利用著陸緩沖裝置可以明顯降低降落傘的面積、減小回收系統(tǒng)的重量，同時(shí)大幅度降低飛行器著陸時(shí)的沖擊載荷。近些年來，著陸緩沖技術(shù)有了些新的發(fā)展。
