Drones

Martin J Dougherty

内容简介

Little more than ten years ago drones were barely used, but now more than 50 countries have them in service and they are not only changing how wars are fought but how crops are sprayed, how underwater pipelines are monitored and even how sports events are filmed. If it’s too risky to send a manned aircraft to survey the intensity of a hurricane or a combat zone, or too costly for conservation wardens to chart the movement of wildlife, drones can be used. Used for reconnaissance work and mapping as well as launching missiles, drones can fly autonomously or be controlled by remote control. Peering into a volcano about to erupt, checking how fast a forest fire is spreading, exploring the wreck of a sunken ship, charting your enemy’s position and taking out a military target—these are just some of the uses of drones today. From drones the size of a fingertip to drones that can carry soldiers, from single rotorcraft to multi-rotorcraft to propeller craft drones, Drones expertly examines these complex vehicles, which are not only very different from manned aircraft, but also very different from each other. Illustrated with more than 220 colour photographs and artworks, Drones is an exciting, accessibly written work about the latest in military and civilian aviation technology.
