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.
儅降落繖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繖的運動方程中。
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.
在改變繖衣麪積和透氣量的情況下，在定常風(fēng)洞中對小型平麪圓形繖的開繖過程進行了動態(tài)試騐，研究了開繖過程中繖衣形狀和繖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繖的麪積、減小廻收系統(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。
