An unmanned aerial vehicle (UAV) ( commonly known as a drone) is an aircraft without a human pilot on board. UAVs are a component of an unmanned aircraft system (UAS); which include a UAV, a ground-based controller, and a system of communications between the two. The flight of UAVs may …

Sensors are usually thought of in terms of physical devices that receive and respond to electromagnetic signals – from everyday sensors in our smartphones and connected home appliances to more advanced sensors in buildings, cars, airplanes and spacecraft. However present day physical sensors are severely limited in range to continuously …

Drones are increasingly making an impact on society and economy. Drones are used by the military for intelligence gathering, anti-aircraft target practice, and also for weapons platforms. They are also used for many civilian roles such as agricultural surveillance, mapping, tracking, search and rescue, traffic monitoring, firefighting, weather monitoring, engineering …

Torpedoes are self-propelled guided projectiles that operate underwater and are designed to detonate on contact or in proximity to a target. For the U.S. Navy, the modern torpedo enables submarines to defeat surface and undersea threats and gives surface ships and aircraft the means to reach beneath the surface and …

Some parts of our bodies can repair themselves quite well after injury, but others don’t repair at all. We certainly can’t regrow a whole leg or arm, but some animals CAN regrow – or regenerate – whole body parts. So what can we learn from these regenerative animals? Regeneration means …

One of the biggest problems with trying to get torpedos to travel faster is the fact that water is a thousand more times dense than air, so in order to overcome that resistance researchers have had to try a variety of different techniques. One of the  phenomenon called supercavitation uses …

Unmanned Aerial Vehicles (UAVs) are growing at frentic pace driven by civil, consumer and military requirements. In order for a UAS to safely navigate in the already crowded aerial environment of the modern world, the U.S. Federal Aviation Administration (FAA) and other international organizations have mandated that unmanned aircraft must …

Military today is more reliant on space than ever before including ISR, Electronic warefare, Communications, Command and control and ballistic Missile defence. The joint warfighter uses space to satisfy an ever expanding and diverse set of requirements such as  cutting the fog and friction of war or to enable net-centric …

US, Russia and China are in race for Hypersonic Weapons that shall provide prompt global strike capability.  Russia’s Avangard hypersonic missile system became operational in Dec 2019, defence minister Sergey Shoygu has said. The intercontinental weapon can fly 27 times the speed of sound and, unlike a regular missile warhead, …
