1、未来空中交通工具(A future vehicle)the lamv is a vertical take-off and landing aircraft that can fly in a quick, quiet, and agile manner. it is a new type of vehicle that combines the speed of an airplane and the vertical take-off capability of a helicopter with some characteristics of a ground vehicle, but

2、without the limitations of any of those existing modes of transportation.lamv是一种垂直起降航空器，能以快速、低噪音、灵敏的方式飞行。这是一种新型的运载工具，它将飞机的速度、直升机的垂直起飞实力与地面运输工具的某些性能结合到一起，但却没有这些现行运输方式的局限性。the lamv is not operated like traditional fixed - or rotary-wing aircraft. it has only two hand-operator uses to direct the redund

3、ant computer control twists to select the desired operating altitude and moves fore and aft to select the rate of climb. the right-hand control twists to select the vehicles direction and moves side-to-side to provide transverse (crosswise) movement during the hover and early-transition-to-flight ph

4、ases of operation; it also moves fore and aft to control speed and braking. simply put, the lamv is user friendly.lamv的操作不同于传统的固定翼飞机或旋翼式飞机。它只设有两个手操限制器，操作员通过它们来操纵冗余计算机限制系统去执行所需的飞行动作。转动左手限制器可选择所须要的飞行高度，前后移动左手限制器可选择上升速度。转动右手限制器可选择飞行方向，左右移动右手限制器可限制回旋时和从起先过渡到飞行阶段的横向动作;还可前后移动右手限制器限制速度和制动。简而言之，lamv对用户来说是易于

5、操作的。the lamv of the future will be 18 feet long, 10 feet wide, and 6 feet high and weight 2,200 pounds. it will hold four passengers and a payload of 875 pounds (including fuel). the vehicle will have a maximum rate of climb of 6,400 feet per minute and an operational ceiling of 30,000 feet. it will

6、 attain a top speed of 390 miles per hour at an altitude of 6,000feet and a cruising speed of 350 miles per hour at 25,000 feet, and it will have a maximum range of 900 miles at 80 passenger miles per gallon. the lamv also will be quiet enough to function as an acoustic "stealth" plane at

7、500 feet. it will have a vertical take-off and landing capability and emergency airframe parachutes, and it will be capable of using various fuels.将来的lamv长18英尺，宽10英尺，高6英尺，重2200磅。它可运载4名乘客，有效负荷为875磅(包括燃料)。它的最大爬升速度为6400英尺/分，好用上升限度为30000英尺。在6000英尺高度的最高飞行速度为390英里/小时，在25000英尺高度的巡航速度为350英里/小时，在每加仑燃油的客英里数为80时的最大航程为枷英里。在500英尺高度时，lamv的噪声会很小，可作为"隐"声飞机运用。它将具有垂直起落实力，并配备有应急机体着陆伞，而且它将能够运用多种燃料。
