Northrop B-2 Spirit



In-2 - it is an American strategic bomber production, which is part of the third generation of stealth aircraft. This air unit is not considered to be "invisible", since there are special systems that can identify it. But thanks to a little visibility to enemy air defense aircraft almost was not replaced, as had a great level of survival.

The design of the aircraft is made according to the "flying wing" scheme with no vertical tail. Splitting guards function as rudders. They were installed at the ends of the wing. The main part of the aircraft is built of aluminum and titanium alloys with a small application of carbon fiber reinforced plastics with a polyamide and bismaleimide matrix with increased heat resistance. The main bearing component is a titanium single-spar cabin, which is located in the central front of the hull and associated intermediate sections. They are attached to the carbon fiber console wings.

The thickness of the titanium panels monolithic caisson - 23 mm. A number of titanium element is constructed with the addition of the diffuse welding and superplastic forming. Some of them are the most long-length in the United States Air Force.

Form aircraft in terms 12 formed by straight lines, which makes it possible concentration of total reflection in a horizontal plane of the main bottlenecks in certain sectors. The underlying chetyrёhlepestkovaya scheme. Parallel to the rear and front edges of the housing and hatches, engine compartment and the flaps landing gear and air intakes create shells X-shaped placed 4 main reflection sector. In 2 sector with front and rear hemispheres.

With front and side angles bomber has no flat surfaces and straight lines. The wear of the wing is located internal styloid radar absorbing construction with honeycomb core, radio-absorbing coating. The front edge of the plane body sharp, has no kinks, with a sweep 33°. The trailing edge is in the form dvoynogoW. On semispan is the top point of fracture. Wing In-2 performed by supercritical profile.

On the airplane engine installed 4 - 2 on each wing near the bomb bay. Especially for radar stealth bomber engine nozzle constructed flat. This also contributes to a form of isotropic scattering outgoing waves, since the plane is made by blending the elements and the minimum number of projections. All the slots on the outside surface of the aircraft is completely closed up, and the arms and motors are inside the structure.

The crew consists of two people. They are hermetically sealed cabin. In every workplace there is a full set of controls. Entrance to the cabin is located in a compartment of the nose landing gear is carried out by means of a folding ladder. In the same compartment of a button engine start and basic aircraft systems. Most often they are used in the event of an alarm. Cabin four glazed sandwich panels, which provide inspection 200 in the horizontal plane°. The panel coated with a special layer having photoreactivity, which becomes opaque when the light impact of a nuclear explosion. Radar radiation can not pass through it, because there is gold-coated. During piloting aircraft pilots protivolazernye wear glasses.

In hvostovoychasti between housing sections and consoles of the wing fuel tanks are located. For cabin crew on top of the fuselage refueling system is the receiver of fuel in flight. In-2 can refuel planes K and COP-135-10.

By-wire flight control system kvadrodupleksnaya, digital, with more responsive drive. It consists of four calculators and can continue to operate at two failures. Air data computer with the presence of 20 unobtrusive pressure sensors.

The complex on-board equipment includes a navigation subsystem NSS class. Its members included 2 interconnected blocks: IMU inertial and astroinertial AIU. At present 8 CRT color multifunctional indicators, according 4 for each pilot.

History of the project In-2

The history of the creation of a heavy bomber dates back to 1979 with the ATB (Advanced Technology Bomber) program. At that time, the Cold War between the USA and the USSR was at its peak. The elections in the United States fell during this period, in which R. Reagan promised to restore the American armed forces. In August 1980, the Ministry of Defense announced its intention to create a number of unobtrusive promising aircraft, which included the ATV program.

As a result of the preliminary estimation of a competition to develop a new bomber won the two teams: Lockheed Rockwell and Northrop Boeing. Both of them received sufficient funding and research contracts. In late October 81 year won Northrop Boeing team.

The proposed project has received codification in-2 labeled «Spirit». In the middle of 80-ies there was a hitch with the design of the aircraft, which delayed the start of flight testing on 2 years and resulted in increased funding to 1 billion dollars. By 1989 year according to estimates for the project of a new low-profile bomber as a whole spent 23 billion dollars.

The first prototype assembled in the factory №42 Air Force in California, in the same place, and it demonstrated the public. And he made his first public flight in July.

Due to the high cost of enormous built just copy In 21-2. Almost all of them are named after US states. Last, the "Spirit of America" ​​under the board 82-1066 number have adopted in July 14 2000 years.

Modernization bomber

The US Congress in 2008 funded a program to modernize the weapon control system against ground moving targets. In December of the same year, a contract was signed with the creator company to improve the radar system, as a result of which the system was transferred to a different frequency range. In April 2009, the carrying capacity of the V-2 was upgraded. Now he could carry up to 13 kg of cargo in each compartment. In 500, the company was able to solve the problem of cracking the aircraft's metal panel.

In April, after 2 year ended bomber tests with the presence of new programmnogoobespecheniya, navigation and communication systems. And at the end of September 2012 was completed modernization In-2 the installation of a new radar AN / APQ-181 the presence of AFAR. Additionally, we install a new communications system and avionics.

In-2 - it is not only the most expensive aircraft in the world, but also in the history of aviation. For the period of 1998, the cost of one unit in the aircraft-was 2 1,157 billion dollars. ATV cost of the program has cost America 45 billion dollars, and the total cost, taking into account R & D for a single instance 2,1 billion dollars.

The first-2 used for other purposes during the NATO operation in Yugoslavia 1999 years. He was also actively involved for all sorts of percussion operations in Afghanistan and Iraq territories. In 2003, the aircraft used in the operation "Iraqi Freedom» (22 sorties). In 2011 year - the operation "Odyssey. Dawn, "was used in the three-2 in Libya.

In-2 bomber

Northrop B-2 Spirit is a strategic bomber of the Northrop firm, the main aircraft of its class of the US Air Force in the late XX - early XXI centuries. Its first flight took place on November 22, 1988. At the beginning of the century, 21 aircraft were in service. The B-2 is made using the "Stealth" technology, it practically cannot be seen by air target detection devices.

This is achieved by the geometry of the airframe (no sharp bends, kinks between mating parts plating), the use of composite materials, the use of special coatings. The aircraft is capable of performing combat missions both at high altitudes, and in small, in particular, it can be to fly in the mode of rounding terrain.
