Unmanned Aerial Vehicles
Eventually, certain flight system parameters evolved to a saturation level and further development did not attract interests of many. Parameters like propulsion and aerodynamics have reached a saturation point in terms of development and evolution. Most of the present day drones use single propeller and a unique design which almost all the flight makers follow. Additional features like on board surveillance equipment, stealth parameters and soundless flight are considerably dealt with by the Drone manufacturers and designers. USA has been an initiator, but Israel has become a master in drone system design and selling. Israel adhered to the business of aircraft making since ages, which starts from the first Gulf War. The World trusts Israel's make from when it proved victorious over the Syrian Air Force attack during 1982, using its manned and unmanned air resile against the strike. News revealed that about 86 Syrian fighters are brought down in a considerably and comparatively short time. This impact has been a cusp for Israeli aircraft reign, as well as for other Air force units around the world. Many nations initiated developmental process to bring out indigenous UAV Systems and few others started to purchase 'talent' and product from Israel.
Best in class drones have come into existence out of technological dominance desires, security demands, and other peculiar demanding applications. And of course, UAVs can be affirmatively used in several other applications including civil surveillance, internal anti-social elements surveillance, industrial purposes etc., against predominant military deployments. Use of drones is back to form now, after a short gap since the last noticeable war rage. US Army has reportedly used drones for surveillance and unmanned aerial attacks in its 'anti-terrorist' operations in the Afghan territory after the World Trade Centre has been devastatingly struck by a plot contrived by an anti-social group residing in the Middle-East on 11th September, 2001. Later, in the recent past it is again the US Army that used a drone made by Lockheed Martin, and named it Polecat, to surveil the Kingdom of Gadhafi, Libya. It was reported by the concerned department at Jawaharlal Nehru University, Delhi that, early in 2011 China manoeuvred UAV drones along the Indo-Chinese border while the Himalayas witnessed the act. Drones are expected to make both plausive as well as caustic news more than ever, nevertheless every nation wishes not to be biased for either kind of news.
