Fighter F-22 Raptor

 

Fighter F-22 Raptor is a multi-purpose apparatus developed jointly by the most successful companies in the US aircraft industry. This project was launched to replace the outdated model of a fighter F-15 Eagle. The new aircraft class F-22 is the sole representative of the fighters of the fifth class, which is in service with the US Air Force.

The history of the aircraft F-22

The US military has long planned to order the production of more high-quality machines, which would differ in their characteristics from all existing aircraft. So, at the beginning of the year 1981 the Air Force command were made the basic requirements for a new fighter. The most important equipment was the most thorough and new avionics and engines with computer controlled. In addition, the machine has to be virtually invisible to all enemy units, and for all that it has to perform a lot of functions and missions.

In the summer of 86, a competition was started to create a new device, while two teams were set up to create a new unit, 50 months were allocated for the design. Both products were ready at the beginning of 90 year, they were designated as the product YF-22 and the product YF-23. Due to the fact that during the design and manufacturing in the 80-ies a large number of funds were used, the manufacturers had to discard the side-scan radar installation and some other optics and protection systems. The customers themselves were forced to abandon this equipment, since the installation of this progressive equipment would lead to a greater cost of further development of the F-22 project. The winner in this contest in the summer of 1991 year was announced the machine, which was created by such companies: Lockheed, Boeing and Dynamics.

The first aircraft model F-22 made separation from the runway in September 97 years. In comparison with the original version of the project, this unit has a power plant with much higher rates of thrust - 15,8 thousand kgs. The engines have the ability to change the plane in which the thrust vectors go. This machine is different from the version of the prototyping and the structure of the body.

For serial production of F-22 2001 fighter started in the year. And in 2004, the first machine of this class have been transferred to the military base of the US Air Force under the name "Nellis". Since the start of production and to 2004 years 51 fighter was created. The first combat squadron consisting of aircraft F-22, 2006 was equipped in the year and was based at Langley.

At the beginning of 2006, the US government planned to order 384 aircraft of this class, but in 2008 this amount was reduced to 188, and at that time it was already ready 127 units. This reduction in the order was caused by the global economic crisis and the relatively high cost of the aircraft. Due to all this, the government has made big bets on a cheaper and more efficient F-35 machine. In addition, in 2009, the government cut back funding for the F-22 Raptor fighter project. Also in 2011, the US Congress announced the termination of further development of this aircraft in favor of F-35. The last production car F-22 Raptor was made in December 2011 year. For the entire time of serial production, 195 machines of this type were created.

Features design multipurpose fighter F-22 Raptor

The basis of the development of the new car designers put basic credo: the first saw - first destroyed. For these indicators in a car was found a lot of the best masking systems and reduce the visibility of the type of Stealth.

A feature of this fighter was the placement of weapons in the interior of the aircraft, which significantly reduces visibility. Yet, on the wings of the aircraft has seating for weapons, but they were not used. This decision designers significantly increased the quality of the universal machine.

The body of the fighter on 40% consisted of new composite materials, the use of which significantly reduce the mass of the structure. These materials were presented carbon fiber with high resistance against overheating. As part of the design of widely used materials that absorb radio waves. Many items were equipped with PCM, which are made of bismalemida, they can withstand the temperature of 230 degree.

Such constructions as canopy chassis compartments were made in a sawtooth shape. This construction has contributed to more efficient dispersion of electromagnetic waves, which reduced the visibility of the machine in flight to enemy radar. Aircraft wings F-22 Raptor had a diamond shape with the vertical stabilizer of the type V-shaped. With regard to the survivability of the machine, it has been designed taking into account the aging shock incendiary shells produced in Russia, which had 30 millimeters caliber.

The Raptor power plant is represented by two P & W F119-PW-100 engines, which are equipped with jet nozzles with a flat structure. This scheme significantly reduces the visibility in the IR spectrum. On these engines are installed afterburners. The weight of the device is represented by the thrust in 15 876 kgf. Without the application of the afterburner, the engines produce power of 11 thousand kilograms. It should be noted that even without the use of afterburner, the car easily overcomes the speed of sound, and these numbers are possessed by a certain number of aircraft. The fighter jets are made of special ceramic materials, which have high rates of absorption of radio waves, which also reduces the visibility of the apparatus.

The composition of avionics installation includes two computers with the designation of the CIP. Each system consists of this 66 modules, and at the heart of each module installed 32-bit processor i960 class.

The onboard radar system is represented by the installation of AN / APG-77, which is equipped with a phased array antenna. A feature of the antenna is that it consists of 2 thousand elements that produce radiation and reception of signals. This setting allows you to detect targets at a distance of 225 kilometers, and the range of radar installation is 525 kilometers. This radar is equipped with protection systems that prevent signal intercept enemy. Aircraft Radar allows you to find the goal in such a way that the enemy will not notice this and using their equipment.

F-22 Raptor

As for the combat power of the aircraft F-22 Raptor, it was presented 20-millimeter cannon class M61A2 Vulcan, which can be used to produce 480 volleys. In addition, the car carrying six missiles air-to-air with the designation AIM-120C AMRAAM, also installed two missiles AIM-9M Sidewinder. On board the machine has been placed and the bomb load, which consisted of corrected bombs JDAM model and guided bomb GBU-39 type shells. A feature of F-22 fighter was that he could make the attack at supersonic flight speeds.

Nazis when they released their first supersonic fighter, too, thought that they were the navel of the earth, and the Soviet pilots shot down it like a fly, and the Americans, and they, too, the Germans, showing off their F-22 sit in a puddle, because the truth will always be on the side of Russia
