The hottest U.S. military research and development

According to reports, U.S. Navy officials revealed that the U.S. Navy research laboratory is testing a mini UAV that is only the size of a CD. This UAV is designed with special acoustic, meteorological and chemical detection sensors, and can fly in batches to dangerous areas to perform monitoring tasks

according to reports, US Navy officials revealed that the US Navy not only caused the relative error of indication to exceed the standard, but the military research laboratory is testing a miniature UAV only the size of a CD. This UAV is designed with special acoustic and pneumatic sensors. When removing debris, it must be shut down for image and chemical detection, and it can fly in batches to dangerous areas to perform monitoring tasks

this UAV is called "close combat concealed autonomous unmanned disposable aircraft" (cicada), which can carry a variety of detection equipment and fly in batches to remote areas or areas inaccessible to personnel. U.S. Navy officials said that the project has lasted for several years, but it is still in the laboratory development stage and is waiting for more funds to be invested in the actual deployment and application

"when performing some tasks, the UAV can effectively transfer payloads in batches, and has obvious cost advantages." Aaron Kahn, a senior aerospace engineer at the US Naval Research Laboratory, said

cicada micro UAV is called "flight circuit board" by Kahn. It can fly to the predetermined location autonomously, and the error can be controlled within 15 feet (about 4.5 meters). It is also a glider that can glide and descend from an altitude of 29000 feet

the micro UAV has no camera or photoelectric sensor, but is equipped with weather sensors, acoustic detection technology or biochemical detection equipment. Kahn explained that the flight distance of this UAV is proportional to its release height: its glide distance is about three times its release height. On the ground, UAVs can be clustered through relatively simple algorithms and less data association

the project is self funded and independently developed by the Naval Research Laboratory. More test flights will be carried out at the Aberdeen Proving Ground in the second half of this year

it is reported that a cicada UAV can form a 6-inch cube to better perform regional denial and large-area monitoring tasks. Due to the large number, small size and low price, these UAVs cannot and need not be recycled after release. They can use their special sensors to check whether there is chemical or biological pollution in the target area, or measure the relevant meteorological parameters of the storm area, so that personnel can avoid getting too close to the dangerous area

this kind of micro manufacturer metal shear testing machine feature UAV can be mass produced by using automatic facilities, so the cost of each UAV can be as low as hundreds of dollars
