Deadly Saab JAS 39 Gripen

Army and Weapons | Deadly Saab JAS 39 Gripen | JAS-39 Gripen is a multi-role fighter jet berpenggerak single Swedish-made Saab Aerospace Company, as the product of the pride of the Swedish JAS Gripen native has also been used by the Air Force Czech Republic, Hungary, South Africa and Thailand, prepared for the Gripen fighter aircraft to replace the old Saab 35 Draken and Saab 37 Viggen fighter as the fourth generation of modern technology.
The development of Gripen began in 1982 after Parliament approved the use of the name comes from the abbreviation JAS Jack Attack Spanning and name Gripen (Griffin) taken from a public competition to name the new Swedish aircraft.Sweden chose to develop the Gripen rather than selecting a series of variants of the F-16, F-18, F-5S and F-20 Tigershark because it believed in the ability of its own.
Gripen was first flown on 26 April 1987 at Saab's 50th anniversary and the first prototype flew on 9 December 1988.The development of Gripen project done with BAE Systems and in 1995 a consortium of companies dibetuk Saab-BAe Gripen AB who served as a manufacturing and marketing of the Gripen internationally, this cooperation continues again in 2001 until 2004 and in January 2005 Saab fully responsible for the marketing Gripen.
On 26 April 2007, Norway signed an agreement to participate in the development of Gripen in the future and the contract value is NOK 150 million and lasted for two years, then in June 2007 Thales Norway A / S signed a partnership contract for development of the Gripen system of communication, and in December 2007 from the Danish technology company Terma A / S also participated in the development of technologies with a contract value of USD 10 billion over 10-15 years which also ensures Denmark to vote on 23 April 2008 Gripen.Pada demonstrator version of the dual-seat aircraft is completed, the aircraft also called the Gripen Demo / Gripen E / F or even MS-21, the jet engines used Volvo Aero RM-12 turbofan Glygmotor Volvo production which is the development of jet engines General Electric F-404 A turbofan, the engine is also used by F/A-18 Superhornet, some component parts are made at General Electric USA later in the raft at Volvo Aero in Sweden, has a maximum speed of mach 1.1 with a 80.5/54 kN traction.
Gripen Demo inaugural flight took place on 27 May 2008 lasted about 30 minutes with a maximum altitude of about 6400 meters (21,000 feet) and on 21 January 2009 Gripen Demo flying up to speeds of Mach 1.2 without stopping to test the strength supercruisenya.Gripen new generation Gripen NG or amended by the addition of fuel tank capacity by 40% and a payload capacity of 14000-16000 kg and the addition of two pylon heavy loads, Radar PS-05 / A and the antenna AESA and ready to test in mid-2009.
Saab conducted a study to create versions of a fighter aircraft carriers since the 1990s and in 2009, Saab launched the naval version because of demand from India and Brazil, in 2010 the Swedish Government gave the contract for 4 years to improve the Radar Saab Gripen and other equipment as well as lower operating costs with a plan that would order the latest variant in addition to JAS 39 Gripen NG E / F will be expected to enter the Swedish Air Force in the year 2017.Desain Delta-wing aircraft and Canards wear (a small wing mounted aerodinamic head planes) which serves to obtain optimal control and aerodynamic power during flight maneuvers or take-off and landing, avionics electronic warfare support a more programmatic and make the aircraft capable of carrying weapons without reducing the maximum aerodynamic power
Design Canards indeed serve to help the aircraft to fly in a short runway of about 800 meters in the testing and also can serve as a major brake force that drives the plane down (downforce) to enable the aircraft to stop the wheel in a short distance, the estimated price of the aircraft about 300 billion dollars, quite expensive but pays off with more ability and according to sources from sweden it only takes 2 / 3 the cost of the manufacturing cost of the Saab Viggen.
Gripen radar using the PS-05 / A Pulse Doppler X-band radar developed by Ericsson and Marconi GE based on the Blue Vixen radar used on the Sea Harrier aircraft which successfully resisted the Eurofighter aircraft radar, radar is able to detect, locate, megidentifikasi and automatically track several targets in the areas above and below, the tanh and sea and air in all weather conditions, radar can guide four air-to-air missiles like the AIM-120 AMRAAM, MBDA MICA simultaneously to four different targets, on 7 March 2009 Saab SELEX Galileo signed a partnership with AESA Radar for development based Raven from Selex Galileo AESA Radar Vixen and PS-05 / A, the radar can scan 200 degrees, slightly to the left rear and slightly to the right rear and on 9 September 2009 Gripen International offers a source code of the AESA as a bid Gripen for India.
Has three full color cockpit displays and digital emergency instrument presentation is unique, lay out the cockpit with an interface that allows the pilot work, the control stick and throttle left hand and a larger cockpit 30% of the aircraft class is dominated by three (15.7 x 21 cm) active matrix liquid crystal multi-function display with a wide angle 20 x 28 degrees head-up display (HUD) is equipped with a light sensor to the computer and contrast control.
Gripen is the uniqueness of the plane can be landed on the tarmac highway to refuel from the fuel tank in an emergency and fly again in a moment, the following picture Gripen test flying on the highway with a size of 17 x 800 meters:
