您要查找的是不是：
- An aircraft whose horizontal stabilizing surfaces are forward of the main wing. 鴨式飛機:水平穩定面在主機翼前方的飛行器語(yǔ)源。
- Beam string structure (abbrev.BSS) is an inner equilibrium system whose bending resistance member and tension member is linked by brace strut. 張弦梁結構是一種用撐桿連接抗壓彎構件和受拉構件而形成的自平衡體系。
- Much more increase of maximum lift-to-drag ratio can be obtained with a forward-swept main wing with a small sweepback angle leading edge. 主機翼前掠角較小時(shí)，鴨翼改善和提高升阻比的效果比較明顯。
- An upper canard, which is in the vicinity height of forward-swept main wing, could improve the maximum lift-to-drag ratio. 高于主機翼的鴨翼對最大升阻比的改善較多，但也不宜過(guò)高。
- At the same time the canard surface creates a downwash which degrade the main wing's performance. 與此同時(shí)，鴨翼面產(chǎn)生下洗氣流，它使主翼效率下降。
- When install aileron, please notice the aileron and main wing whether they are in the same middle line. 安裝副翼時(shí)注意副翼和主機翼要在同一中線(xiàn)上。
- If this load centroid is behind the elastic axis of the wing structure, then a nose-down twist of the main wing surface results. 如果該載荷重心在機翼結構彈性軸之后，則引起主機翼表面前端向下的扭轉。
- This main wing is made of a carbon/epoxy composite, is about 2 m in span, uses a NACA 4415 airfoil section, and pivots just ahead of the quarter chord. 主翼由碳/環(huán)氧合成物制成，跨度約為2米，使用NACA 4415 的翼剖面，將支點(diǎn)設在四分之一弦的前端。
- To get in, you'll have to enter the main wing from the east wing.Then, go through the passageway on the second floor of the main wing. 要進(jìn)入那里，你必須先從東翼進(jìn)入主樓，然后通過(guò)主樓二層的走廊。
- A short,winglike control surface projecting from the fuselage of an aircraft,such as a space shuttle,mounted forward of the main wing and serving as a horizontal stabilizer. 鴨式飛機的水平安定面和升降舵從一架飛行器伸出的一個(gè)短的翼狀控制平面，如航天飛船的機身，被安在飛機翼前方，作為水平穩定器。
- A short, winglike control surface projecting from the fuselage of an aircraft, such as a space shuttle, mounted forward of the main wing and serving as a horizontal stabilizer. 鴨式飛機的水平安定面和升降舵從一架飛行器伸出的一個(gè)短的翼狀控制平面，如航天飛船的機身，被安在飛機翼前方，作為水平穩定器
- Improvement Measure of the Brake Beam Bracing Strut of Railway Freight Cars 鐵路貨車(chē)制動(dòng)梁支柱的改進(jìn)措施
- Discussion of Strengthening and Improving Inspection Quality of Cracks in the Bow-Shaped Brake Beam Bracing Strut 加強和改進(jìn)弓型制動(dòng)梁支柱裂紋檢修質(zhì)量的探討
- It consists of fuselage,canard,two main wings,wingtip-fin,landing gear and engine,etc. 它由機身、主翼、中翼、前翼、翼尖小翼、起落架以及發(fā)動(dòng)機等部件組成。
- The Palestinian Authority is in a desperate state, fighters nominally allied with the two main wings of its supposed "unity" government slaying each other on the streets of Gaza. 巴勒斯坦權力機構已經(jīng)陷入絕望，名義上與所謂的“統一”政府兩大派別結盟的好戰分子在加沙的街道上相互砍殺。
- buttress bracing strut 扶壁剛性梁
- MAIN GEAR SHOCK STRUT SERVICING. 主起落架減震支柱勤務(wù)。
- bracing strut 撐桿,支柱撐桿
- The main impediment to growth is a lack of capital. 影響發(fā)展的主要障礙是缺乏資本。
- Crowds thronged the main square of the city. 城里的大廣場(chǎng)上擠滿(mǎn)了人群。
