| 1. | The landing aircraft had bisected their own runway . 正在着陆的飞机从横里切过他们的跑道。 |
| 2. | Hold at holding point , landing aircraft 在等待点等待,有降落飞机。 |
| 3. | Vertical take off and landing aircraft 垂直起落机 |
| 4. | The lamv is a vertical take - off and landing aircraft that can fly in a quick , quiet , and agile manner Lamv是一种垂直起降航空器,能以快速、低噪音、敏捷的方式飞行。 |
| 5. | Auckland tower : " previously landed aircraft says did not need to use brakes , ten to fifteen millimeter deep water on runway " 奥克兰塔台: "目前降落航机无需使用煞车,跑道积水10至15公厘. |
| 6. | The local controller also updates weather conditions for your pilot and monitors the spacing between your plane and other landing aircraft 本地管制人员也向飞行员提供最新的天气信息,并监控飞机以使其与其它着陆飞机保持安全距离。 |
| 7. | Usually blowing from the west , it converges with the background winds which typically blow from the east . . the convergence of these opposing winds sometimes produces windshear for landing aircraft 海风通常从西面吹来,与东面吹来的背景风相汇聚,从而产生辐合,有时为著陆的飞机带来风切变 |
| 8. | As there was a slight delay in ci665 in commencing take - off roll , and with the next landing aircraft five nautical miles away , the tower controller decided to withold ca1074 from departure and intended to instruct ca1074 not to enter the runway and to hold position 由于ci665客机在开始起飞滑跑时有轻微延误,而下一班抵港航机只离跑道五海里,塔台控制员?定收回ca1074起飞的指示,并准备指示ca1074停止进入跑道和保持原来位置。 |
| 9. | Ussr admiral kuznetsov aircraft carrier the kuznetsov class heavy aircraft carrying cruiser , also known as project 1143 . 5 or orel class , was constructed at nikolayev south shipyard on the black sea in the ukraine . the kuznetsov aircraft carriers displaced roughly 65 , 000 tons and for the first time carried conventional take - off and landing aircraft 1983年2月22日,前苏联在尼古拉耶夫船厂开工建造第一艘大型航空母舰,该舰又被称为1143 . 5级, 1985年12月5日下水, 1991年1月21日正式服役。 |
| 10. | A large planar microphone array , which consists of 111 microphones , was successfully applied to obtain a two - dimensional mapping of the sound sources on a landing aircraft . the focus of study in this paper is on the landing gear noise source . the spectra , directivities and sound pressure levels of flap side - edge noise of 7 narrow - board commercial aircraft and 7 wide - board commercial aircraft are presented . it is found that the landing gear noise spectrum is broadband with some single tones in some cases . the directivity of the total sound pressure level of a landing gear noise resembles that of a horizontal dipole . the level differences between the various aircraft landing gears are larger than those expected from the airspeed differences . it is thus expected that the louder noise emission of the landing gears can be reduced by redesigning 应用由111个传声器组成的平面传声器阵列对当前流行的民用客机进场着陆过程中的机体噪声源进行了实验测量,本文对七架窄体客机和七架宽体客机的起落架噪声进行了分析,得到了起落架噪声的频谱特性、指向特性和声级变化.研究发现,起落架噪声的频谱是由宽频随机噪声与一些较为明显的单音噪声源组成,起落架噪声的指向性类似于一个水平放置的偶极子.不同飞机起落架噪声的声级相差较大,这说明可以通过重新结构设计降低起落架噪声。 |
