Saab JAS 39 Gripen Aircraft

Saab JAS 39 "Gripen" (Griffin) is a fighter aircraft from Sweden, produced by Saab. The aircraft was sold by the company Gripen International, a joint venture between Saab and BAE Systems. This aircraft has been used by Swedish air force, Czech Republic, and Hungary, and has been ordered by South Africa and Thailand.

Design

in designing this aircraft Saab kanard choose a design that is not stable. Kanard provides pitch rate is high and low resistance to allow aircraft to fly faster, farther and more mengankut load.

The combination of delta wing and Gripen Kanard provide better performance in terms of character fly and take off and land. The total integrated avionics make the aircraft is capable of "program". The aircraft also has an internal electronic warfare devices, enabling him to carry the maximum load without compromising the ability of electronic war.

The desired capability for Gripen from scratch is able to take off from runway 800 meter.Pada original project, all flights conducted from Saab in Linköping basis using reference a "line of the box" measuring 9 m × 800 m runway, runway painted. Braking distance is also shortened by enlarging the air brake (use control surfaces to push the aircraft toward the bottom, making it more powerful brake pressed down and the next step is to rotate kanard forward, memngubah kanard into large air brakes, to push the aircraft down even worse.

One interesting capability of the Gripen is the ability to land on public roads, which is one of Sweden's defense strategy. Once landed, the plane can be filled with fuel and armed again in 10 minutes by 5 people ground crew operating out of a truck, then Gripen flying back to carry out its mission.

For long-term Saab consider using newer machines such as General Electric F414 or a thrust-vectoring version of the Eurofighter Typhoon's EJ200 engine and additional fuel tanks or a fuselage extension separately mileage even further.

Radar

Gripen menggukan PS-05 / A pulse-doppler radar, made by Ericsson and GEC-Marconi, and based on the Blue Vixen radar-owned Sea Harrier (which also inspired the Eurofighter's radar CAPTOR).

The radar is capable of detecting, tracking the location, identify and automatically track multiple targets at the top or bottom of the aircraft, sea land and air, in all weather conditions.

History Of helicopter

What is Helicopter?

A helicopter is an aircraft that lifted and driven by one or more rotors (propeller) large horizontal. Helicopters are classified as a rotating-wing aircraft to distinguish them from ordinary fixed-wing aircraft other. The word comes from the Greek helicopter helix (spiral) and pteron (wing). A helicopter operated by the machine invented by the inventor of Slovakia in January Bahyl.

Compared with other fixed-wing aircraft, helicopters more complex and more expensive to buy and operate, too slow, has a close distance and roaming charges are limited. While profits are movements; helicopters capable of flying in place, backed up, and take off and land vertically. Limited additional facilities and fuel load / high altitude, the helicopter can fly to any location, and land anywhere in the field of the rotor and a half in diameter. Called a helipad helipad.


 Actually, a helicopter trip into a form that is known at the time this takes quite a long period of time. This journey also involves the development of technology and also the inventor and developer helikoter.

The first helicopter flew the man is the Breguet-Richet helicopter, 1907. These helicopters flying in Douai, France on September 29, 1907. This helicopter is still getting help from four people who held the fourth leg. This effort did not get a good record as the first helicopter to fly free. Nevertheless, the helicopter was flying theories prove successful vertical while it is still considered a theory. This is the first machine that could fly by itself carry a pilot vertically as a result of wing lift swivel. This heli use the power of 50 hp Antoinette engine.

Helicopter flying really done by Paul Cutaneous use twin-engine helicopters Antoinette 24 hp at Lisieux, France on 13 November 1907. The flight lasted 20 seconds to a height of 0.3 meter. While the first Gyroplane Helicopter manifold achieved by C4 Autogiro Juan de la Cierva made. Autogiro first flew on January 9, 1923]]. The secret to success hinges on the adoption of a joint system of the flapping blades to the rotor head. While the helicopter which first flew successfully carried out by type of Fock Wulf FW-61 double berotor designed by Professor Heinrich Focke in the year 1933-1934. This helicopter made its inaugural flight on June 26, 1936 and engines powered by the Siemens-Halske Sh 14A-powered 160 hp. Heli was flown by Ewald Rohlfs. These helicopters fly as far as a record 122.35 km and long flown one hour 20 minutes 49 seconds. At other times he flew to a height of 3427 meters and a speed record 122 mph.
