Beijing June 21 news, the future war may no longer be an aircraft cannon, micro-weapons will dominate the battlefield, and give the enemy a greater blow.
According to the introduction, the United States is currently studying micro-machine insects, which will serve as military reconnaissance missions in the future. In addition to their unmanned character, the biggest advantage is that they are extremely compact and the project is very similar to a real insect and is difficult to find. Radar has no effect on them.
As early as 2008, the U.S. began to develop such machine insects. The drone whose body size was close to that of a bee was officially born. It could be used for some shooting tasks. The US Air Force also stated that they will formally enter service in 2015.
Such inspiration really comes from insects in the natural world. Scientists believe that insects have a strong vitality and super flying ability. The wings of insects have evolved through centuries of continuous evolution and are now almost perfect. Richard, a zoologist at the University of Oxford in the United Kingdom, said: “The inspiration for the micro-aircraft is to come from nature. Look at the flying ability of these insects. I think even better than the aircraft, and the future machines are similar to insects, which helps conceal.â€
Scientists also stated that the human aircraft has only a history of more than 100 years, and the wings of insects have reached 350 million years. This is a big gap. We need to learn from them. (Science Network kexue.com Joel)
