- In order to research the guidance technology for unpowered reusable launch vehicle (RLV), an adaptive guidance technology with online trajectory shaping is developed. 摘要為了研究重復使用運載器小升阻比無(wú)動(dòng)力飛行時(shí)的制導技術(shù),以投放著(zhù)陸為背景,提出了一種基于軌跡在線(xiàn)生成的自適應制導技術(shù)。
- First, time replaced by altitude and dynamic pressure as the independent variable of nonlinear equations of motion, which make the trajectory shape correlative to dynamic pressure constrains. 首先,將基于時(shí)間歷程的質(zhì)點(diǎn)動(dòng)力學(xué)方程轉化為基于高度剖面的質(zhì)點(diǎn)動(dòng)力學(xué)方程,同時(shí)利用動(dòng)壓代替速度,使軌跡形狀直接和動(dòng)壓約束相關(guān)。

- The majority of the flight is flown using midcourse guidance, during which the missile makes slight adjustments to its trajectory allowing it to reach the vicinity of the target. 飛行的主要階段使用的是中段制導,在此階段制導系統不斷微調導彈的飛行軌跡使其到達目標附近。
- The patient is still in bad shape. 病人的情況依然不妙。
- After the ballistic trajectory in midcourse was simulated, the aspect angles of warhead target were calculated in assumed scene by coordinate transformation. 仿真了空間目標飛行彈道后,通過(guò)坐標變換得到設定戰情下的彈道目標雷達視線(xiàn)角。
- I'll just rough in the shape of the head and you can paint the sky round it. 我把頭形勾勒出來(lái),你可以在頭四周畫(huà)上天空。
