a future vehicle

while many technological advances occur in an evolutionary manner, occasionally a revolutionary technological appears on the horizon that creates startling new conditions and profound changes. such is the case with the privately developed moller skycar, which is named after its inventor. with his permission, i would like to discuss the military potential of this vehicle. the ruggedized moller skycar variant the military is evaluating is called the light aerial multipurpose vehicle, or lamv (pronounced "lam-vee").技术的进步大多以渐进的方式进行，但有时可能出现突破性进展，带来令人吃惊的新情况和深远的变革。私人研制的"莫勒空中汽车"的情况就是如此，这是以其发明家的名字命名的。征得他的同意，笔者愿意探讨-下这种运载工具的军事潜力。美军目前正在进行评估的加固型"莫勒空中客车"，叫做轻型空中多用途运载工具，或缩称lamv(读作"lam-vee")。

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 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、敏捷的方式飞行。这是一种新型的运载工具，它将飞机的速度、直升机的垂直起飞能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 redundant 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 vehicle's direction and moves side-to-side to provide transverse (crosswise) movement during the hover and early-transition-to-flight phases 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。它只设有两个手操控制器，操作员通过它们来操纵冗余计算机控制系统去执行所需的飞行动作。转动左手控制器可选择所需要的飞行高度，前后移动左手控制器可选择上升速度。转动右手控制器可选择飞行方向，左右移动右手控制器可控制盘旋时和从开始过渡到飞行阶段的横向动作;还可前后移动右手控制器控制速度和制动。简而言之，lamv对用户来说是易于操作的。

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 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 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.未来的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，实用上升限度为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"声飞机使用。它将具有垂直起落能力，并配备有应急机体降落伞，而且它将能够使用多种燃料。
