A researcher at the defence company Boeing has file a patent of invention for a sci - fi - esque cloaking equipment that would protect soldiers from intense seismic disturbance waves generated by explosions .
The just - release patent ( No . 8,981,261 ) to Boeing envisions stopping shock wave using a velum of heated , ionised air travel . Such a " shell " would dampthe military force of explosions . It does n’t build an invisible wall of force , but rather makes shock waves bend around objects , just as some high - tech materials twist igniter and make things unseeable .
A newly patented device could use heated, ionized air to stop shock waves generated by explosions.
Brian J. Tillotson , a fourth-year research fellow at Boeing , said the melodic theme occur to him after notice the kinds of harm suffered by soldiers who serve in Iraq and Afghanistan . " We were doing a much better line of work of intercept shrapnel , " Tillotson told Live Science . " But they werecoming home with brain hurt . "
Though the armor plat on a military vehicle might end the debris from a wayside bomb calorimeter from injuring a soldier , it ca n’t harbor against theshock wavesgenerated by such explosion . The blast moving ridge goes right througha human bodyand cause monumental trauma . ( This is why the action - movie scenes where the hero runs beforehand of an explosion and escapes harm are pure fable . )
Tillotson ’s invention is a equipment that would heat up the air in front of the spot where the bomb goes off . In one version , a demodulator " sees " an burst before the impact moving ridge hits . The detector is associate to an spark author , fundamentally two end of a racing circuit connected to a gravid power source . When the system generates enough current , an arc of electricity jump between the two ends of the circuit , like a bolt of lightning . [ Science Fact or Fiction ?

A schematic of the shock-wave-damping system (10) mounted on a vehicle (18) generating an arc that would meet up with a shock wave (24) from an explosion (22).
That arc wake and ionizes , or charges , particles of melodic phrase . The het up aviation would work as a cuticle by interchange the speed at which seismic disturbance moving ridge locomote , and therefore flex them around a protected soldier , Tillotson said .
reasoned waves(and other undulation types ) circularize faster in red-hot tune , Tillotson enounce . For that ground , the shock wafture would speed up when it strike the heated air around the electric dismissal . As the shock wave speeds up , it would change direction slightly , or refract , away from the person or object behind the arc . That bending occur because of the change in stop number of the wave , and the shape of the surface area of hot airwave the jounce wave hits determines the exact direction .
The mental process resemble the way lenses flex lighter , Tillotson say .
" With a bulging lense you focus the luminosity , " he suppose . " A concave lens spreads it out . " short wave move slower in methamphetamine hydrochloride , so when light gain a glass surface it bends . The lens must be concave to propagate out that luminousness . Because jounce wave move faster in hotter airwave , a ball-shaped or cylindric area of red-hot air will cause the jolt undulation to turn away , this clock time spreading out just like the visible light through a concave lens of the eye , becoming weaker . In doing so that hot - melodic line cuticle could avoid shock wave .
Arc author are n’t the only manner to ionize air . Lasers would also work , Tillotson say . A laser fired across the way of life of an explosion would ionise and heat the air around the beam , creating the lensing effect .
In another method , a funnies of some metal could be direct on the side of a truck , for example . " Put a couple of kilo - A [ thousands of ampere ] through a strip of alloy , and it will vaporize , " he say . The vaporized metal once again wake the skirt air .
One issue for all of these methods of damping blow wave is the amount of power required . But Tillotson noted a lot of inquiry in this area shows promise in diminish that power suck in . In addition , evena high - powered laserdoesn’t have to be on for long , perhaps a fraction of a second , to hot up the atmosphere sufficiently . " It ’s basically a puzzle out problem , " he pronounce of the ability supply .
This is n’t the only technology patent of invention for Tillotson ; he has at least a half - dozen others in areas such as aerodynamics and beamed power sources , and even other method of damping shock waves . Whether this special technology becomes a world will count , as many do , on future interest ( and funding ) from government and the private sphere .
