Energy & Propulsion

In the current environmental climate, energy needs to be conserved and recycled as much as possible to prevent wastage – every joule saved means less fossil fuel burnt. Harvesting waste energy has become a popular target for researchers and scientists, who are coming up with innovative techniques to achieve this. …

Batteries are preferably to be used under circumstances where there is no possibility for charging, and besides this, in fields where it is important to store energy given the smaller mass and volume. Military applications of batteries include radio appliances, lamps or most electricity powered devices and equipment.   Supercapacitors, …

A helicopter, or chopper, is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward, and laterally. These attributes allow helicopters to be used in congested or isolated areas where …

Energy harvesting is the process of collecting low-level ambient energy and converting it into electrical energy to be used as a power source for miniaturized autonomous devices. Examples of this can be seen in structural health monitoring, smart packaging solutions, communication systems, transportation, air and aerospace vehicles, structural biology, robotics, …

The vision for the future soldier is to be combat effective and also highly mobile, adaptive, networked, sustainable with total battle space situation awareness and information assurance. Therefore, he is equipped with night- vision goggles, radios, smartphones, GPS, infrared sights, a laptop as well as batteries to power them. Some …

Integrated circuits and power devices utilized by the semiconductor industry for the production of advanced computers, consumer electronics, communication networks, and industrial and military systems have been almost exclusively based on silicon technology. The requirements of future electronics place a great emphasis on achieving new devices with greater power density …

Batteries are  critical for military missions. Modern soldiers are equipped with night- vision goggles, radios, smartphones, GPS, infrared sights, a laptop all of which depend on batteries to power them. Some of the missions the soldiers perform can take weeks, rather than days, without any ability to recharge; therefore he …

A nuclear submarine is a submarine powered by a nuclear reactor. The performance advantages of nuclear submarines over “conventional” (typically diesel-electric) submarines are considerable. Nuclear submarines are more powerful than diesel-powered submarines because nuclear reactors powering them can run for years without the need for refuelling. Nuclear propulsion, being completely …

Recent advances of high power solid state lasers promises necessary laser power levels required for the Directed Energy Weapons (DEW) systems. However, inefficiencies of the laser components still generate too much waste heat to be managed by conventional liquid cooling systems, especially in an airborne platform where compactness, light-weight and …
