The servos are mounted in a composite tray ? Once again attenuating airframe vibration and extending servo life .
伺服装在一个综合的托盘再度延伸衰减振动和机身伺服生活。
One big difference between the duo and its predecessors is that those batteries are lithium-polymer cells sitting in the wings , near the plane 's centre of gravity , and not nickel-cadmium ones scattered artfully around the airframe .
This dissertation researches and analyses the development on the aircraft airframe cost estimate methods abroad for the past several decades in order to find out a appropriate method for aircraft airframe cost estimate in china .
体研制费用估算的研究成果进行分析、探讨,以求找到适合于我国飞机机体研制费用估算的合适方法。
Nasa 's study focused on applying new techniques to improve laminar airflow , advanced composites to reduce weight , ultra-high bypass engines to create more energy efficiency , new combustors to cut harmful emissions and new ways of integrating engines into the airframe to shield noise levels .
Known as " n + 3 " to denote three generations beyond today 's commercial transport fleet , the research program is aimed at identifying key technologies , such as advanced airframe configurations and propulsion systems , that will enable greener airplanes to take flight around 2035 .
Then last week , other stress tests on an airframe showed that the plane needs strengthening at 18 points on either side of the fuselage just above the area where the wing attaches .
就在上周,机身结构的其他应力测试显示,就在机翼连接的面之上的机身每侧需要强化18个点。
Like the paper-clip , the airframe and its alloy skin are stressed first in one direction as the cabin is pressurised while climbing to its cruising altitude , and then in the opposite direction when depressurised during descent for landing .
