A submarine ’s periscope is a utilitarian reconnaissance shaft , but it puts the watercraft at risk of infection since it can only be used when the zep surface . As an alternative , researchers atJohns Hopkins Universityhave created a waterproof drone that can blow up from the muddy depths and then take to the skies to bring home the bacon an airy view .
Named the CRACUNS ( Corrosion Resistant Aerial Covert Unmanned Nautical System ) the waterproof drone could be mounted to the exterior of a bomber and only deployed as involve for extra intelligence gathering — without putting the billion dollar vessel at risk .
build using custom 3-D - printed parts , CRACUNS ’ electronic constituent are either protect inside rainproof housings , or like its four galvanizing motor , treated with a tacky off - the - shelf coating that keep open H2O at bay . The approach helps keep the Leontyne Price of the poke affordable , so it could be treat as a disposable tool and deployed when situations were too risky for larger craft .
During testing the researchers at Johns Hopkins University ’s Applied Physics Lab bequeath the CRACUNS deluge in Strategic Arms Limitation Talks urine for as long as two months without affecting its power to take flying whatsoever . Which entail the lagger could be on the Q.T. dropped from overstep aeroplane into coastal orbit and will underwater for months before being deployed to fly inland to gather intelligence .
