U.S. navy has taken a different approach to the underwater weapons by making the most of the acoustic energy. A recent patent filed by them has revealed of a new powerful weapon that makes use of sonar to generate “acoustic remote cavitation’ that could destroy torpedoes, mines, and many other hinders. The acoustic source and target can be located in unconfined underwater space and at a distance of at least 100 m apart. The underwater cavitation could be used in superfast sub and missiles. The idea is pretty different i.e. using acoustic energy instead of any bombs or missiles to destroy the targets. It is no doubt a new pin on the idea of underwater weapons. Via: DangerRoom

In this day and age of technology, it’s quite surprising that Navy is still looking for routines to predict the location of the bomb. Believe it or not, it’s true. According to report, the official of Naval Research is interested in getting theoretical and technical methods, which would not only give them a much-needed cushion in terms of prediction of bomb placements but also Naval officers in duty can also identify and localize bomb makers. As advanced sensor networks are the order of the day at present juncture, there is hardly a surprise that Navy is only interested in proposal based on advanced sensor networks. You may ask: What so flash about advanced sensor networks? Advanced sensor networks can play a prominent part in automatically detecting the location of the bomb, which in turn will mean that Navy can neutralize them with less human involvement.

Bionic nose to detect explosives

A new biosensor nose has been successfully developed by the researchers of Temple University School of Medicine that sniffs explosives. To build this biosensor Danny Dhanasekaran and his colleagues genetically engineered a yeast strain with rat olfactory signaling machinery and thereafter by linking it to the expression of green fluorescent protein. Associate Professor of Biochemistry at Temple’s Fels Institute for Cancer Research and Molecular Biology Danny Dhanasekaran said: We suspected that harnessing the potential of the olfactory system, which can detect innumerable chemical agents with unparalleled sensitivity and selectivity, would be of immense value in the detection of environmental toxins and chemical warfare agents even at sublethal levels The yeast cells are then cloned individually with rat olfactory receptors and when the olfactory receptor “smells” the odor of DNT or an ingredient in the explosive TNT, the biosensor turns fluorescent green. The forecast also reveals that day is not far when this bionic nose will be used to detect other hazardous gases and landmines. Via: I4u

Thermal vest to help soldiers combat heat-illness

Earlier we introduced you a newly developed fabric called bio-harness to monitor Psychological state of mind of soldiers. Now, scientists from University of Portsmouth are in the process of testing a new thermal vest manufactured by an undisclosed United States based military contractor that enables soldiers to perform their tasks better for long period of time in extreme hot climatic conditions. To eliminate heat-illness this thermal vest uses a combination of air, liquid and new applications of old technologies such as converting paraffin wax into liquid in chambers within the vests to absorb heat from the body. The test reveals that troops wearing heavy and dense biological and chemical protection frequently suffer heat-illness that can seriously hamper their judgment and decision-making process. The illness can even result to death in extreme climates. Though the test is yet in its early stages of development, it is projected to be used within two years by American troops working in extreme hot climate, especially Iraq where temperature can reach as high as 50 degrees celsius.

Gigantic, spying flying machine

To design some giant flying robotic-plane that can fly of its own for minimum two days and spy everything in the air and on the ground for miles, Air Force has signed up all major aerospace companies. As per expectations, we can now actually see incredible design pouring out of the best minds working on it and among them one is the diamond-shaped shuriken that looks like a Boeing. Nevertheless, according to Defense News, Air Force has to embed sensors themselves on the wings of this plane as per the requirements. To make it lighter, the wings of this SensorCraft are kept empty from inside and can stay in the air at 60,000 feet altitude. Some other designs in the next 5 years unveil designs like B-2-esque flying wing that will consume approximately $12 million. All the planes will be gigantic, whereas the linear distance between the extremities of an airfoil in the area will be around 200 feet with 90,000 pounds or more gross takeoff weight. According to the industry analysts the designs require good size to sport the king-sized, low-frequency high precision antennas fabricated on to the mid section of the aircraft those are especially designed to bestow ‘high gain and foliage penetration radar capability… to defeat extreme difficult targets.’ Defense News further quotes that an ultra high frequency radar system can form fraction on the outboard wings (at least in the Northrop design) to record long-range moving targets in the air, whereas an X-band radar system with antennas planted at the trailing edges of the inboard wing can facilitate planes to spy in the air targets with accuracy. Therefore we can assume that sensors have to function twofold because they spy and support plane too for smooth actions. It seems that sensors can perform more functions then this but I think that their functions can vary according to aircraft design. Nevertheless, it is worth mentioning that these flying spying machines will definitely help to record the data that is essentially important for security reasons and to keep an eye on enemies and on their activities.

Guns from planet ‘bizarre’

Eccentricity doesn’t spare anything!! Not even objects that you equate with style. How would you transform the deadliest objects on earth into objects of bafflement? By designing them with a tinge of wild creativity…. One look at these guns and you would forget that they could kill. Far from their original purpose, these guns do not seem to have even the ‘looks that kill.’ However, they do catch the fancy of art collectors. The shotgun with the viewfinder aside, the rest of the guns look like they have been transported from a different age or possibly, from a different planet altogether. Nevertheless, they do have the looks to grab attention. If you are a lover of ‘all things unique’, these guns are for you!!! Go get’em…. Via: 2dayblog

Bullets made from precious metals

A bullet is a pointed metal cylinder that is shot from a gun. A bullet is a part of an ammunition cartridge. Sometimes, ammunition cartridges and bullets mean the same. Do you know how bullets are made? A variety of metals is used to manufacture bullets. However, since the very beginning, bullets have been made from lead or lead alloys. Copper or an alloy of copper and zinc is used to make bullet jackets. Today, metals such as aluminum, bronze, copper, steel, tin and tungsten are used to manufacture bullets. Lubricants are also used in bullet-manufacturing. Carnauba palm is used to extract carnauba wax. This wax is then used as a lubricant for bullets. Why is lubrication necessary? It helps reduce friction between the bullet and the machinery. Ammunition can be used for a variety of purposes viz. hunting, military, target shooting, and self-defense. That is why different types of ammunition are manufactured to address different requirements. The design of a bullet depends on the size and type of firearm. While a large bullet may jam in the barrel and cause the barrel to explode, an excessively small one would not support the rifling action. Bullet weight is important too. Accuracy, precision, bullet speed, effectiveness at a particular range, target penetration and level of impact are some of the variables that are taken into account while designing bullets. Testing of bullets is a scientific affair that involves a number of mathematical calculations. Military bullets are heavier than the bullets used in hunting, or for self-defense. Lighter bullets are use for hunting purpose. Partially jacketed bullets are generally used for larger targets. Bullets can also be used as accessories. However, such bullets are harmless, and cannot be used for any destructive process. Generally made out of silver, such bullets can be used as dog-tags too. Search the World Wide Web to know more about such accessories.

Boeing has just tested their ahead of its time robotic helicopter that can fly around without any pilot to accomplish its mission successfully. However, this robotic helicopter was tested for only 12 minutes but this spy machine is capable to reach swiftly at 140 knots on 30,000 feet for approximately 20 hours. This flying machine is chiefly designed to spot terrorists from above and to pick them off without any margin for error. I am quite excited to know what kind of goggles or sensors this advanced helicopter is bundled with that enables him to fly itself to spot and pick only terrorists, is the technology applied to develop this spying machine is quite confidential, might be! Whatsoever, not much info is yet unveiled about the spying machine that can be sent to search out terrorists democrats in some major cities but we will definitely keep you posted.
