目前,美国国防部高级研究计划局正在资助所谓的微型飞机研究,这是一些直径只有几厘米的无人驾驶飞行器。由于体积小,这种微型飞行器在远处很难被发现。人们希望把其成本降低到使每个普通士兵都能配备,由于这种飞行器成本低廉,所以即使损失了也无关紧要。该局研究的目标是制造一种能够滞空1个小时、可适时发回图像、单个成本不超过1000美元的外形看起来颇似一架玩具的战斗机。其中一架名为“黑寡妇”的微型机,外观怪异,像个飞碟,靠一个简单的前置螺旋桨驱动,使用电池供能。它已成功地在空中飞行了16分钟,最大时速达到了近70公里。另一架正在研制的微型飞机“直升虫”的外貌更
Currently, the Defense Advanced Research Projects Agency is funding so-called mini-aircraft studies, some unmanned aerial vehicles that are only a few centimeters in diameter. Due to its small size, this type of micro-aircraft is hard to find remotely. People want to reduce their costs so that every single soldier can be equipped, and because of the low cost of such an aircraft, it does not matter if it is lost. The agency's research goal is to create a toy that looks like a toy fighter with a 1 hour hysteresis and the ability to send back images at a single cost of less than $ 1,000. One of the microcommeers, named Black Widow, looks weird, like a flying saucer powered by a simple front propeller and powered by batteries. It has successfully flown in the air for 16 minutes and its maximum speed reached nearly 70 kilometers per hour. The other is developing a miniature aircraft “helicopter ” looks more
