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.
當降落傘在空氣中作非定常運動時，空氣動量的變化率必須包括在降落傘的運動方程中。
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，在定常風洞中對小型平面圓形傘的開傘過程進行了動態(tài)試驗，研究了開傘過程中傘衣形狀和傘衣所受載荷之間的動態(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，同時大幅度降低飛行器著陸時的沖擊載荷。近些年來，著陸緩沖技術(shù)有了些新的發(fā)展。
