Rockwell B-1 Lancer

 

 

Rockwell B-1 Lancer - a heavy bomber of the US Air Force is armed with 1986 city is one of the largest aircraft of its class in the history of aviation. In 2002, in the ranks it was 93 bomber. Design feature in-1 wing is variable in terms of geometry. Sweep the front edge of 1559,5 °.

The design of the aircraft is made by technology "Stealth", the probability of detecting enemy radars minimal.

His replacement in-52 company Rockwell International began developing a strategic bomber class. Initially, the plane had the name in-1, but after some time with the new upgrades, he acquired the name of the B-1VLancer. Officially it was 1 May 1990 years.

In 50-ies it has developed a number of actions to replace the aircraft, the armament of the United States. A good representative of such a plan was in-52. Starting with 60-ies, we have developed a program called AMSA. Later in the year 1969, it was renamed in the program in-1. Formal proposals on request (meaning the offer, exiled in different aircraft manufacturer) In-1 USAF issued in November of the same year. 7 70 June, the company chose the winner of the contest. He was the company North American Rockwell. Also select the engines - turbofan General Electric F101-100.

According to the original program was planned to construct 2 instance for static tests and 5 - for flight. However, almost immediately in 1972 year we made some adjustments in the program, particularly in the static tests given only 1 instance, and on the flight - 3. In 1976 year decided to build a fourth plane as a reference for the start of series production. According to the program we expect to receive in serial 240-1. In 1979 year SAC Air Force felt it necessary to put the aircraft on alert.

R & D went intensively, with a small delay from the schedule. At 76, the first flight of the prototype was planned. In the same year 23 December, it was a little late. In the air, he was picked up by the American test-pilot Ch. Boca, Jr.. This prototype was used to fix flight and practical characteristics. Immediately faced with the problem of electronics in the plane, because it was the first bomber lifted into the air, with the most advanced equipment. The main problem was the complex of avionics, or, to be more precise, its certain part - the onboard defense complex. Although the plane was almost ready, with this complex, the company responsible for electronics, Boeing, was transported about 10 years before bringing it to its full working order.

In April 76, the prototype reached the previously set speed program M = 2, and in September flight tests were successfully completed. In December of the same year, the Pentagon, together with the US Air Force, announced its intention to begin mass production of the aircraft. However, immediately there was a problem. The on-board equipment was finalized and did not particularly worry about this, but the problem arose with a financial issue. If in 1970 the aircraft cost 40 million dollars, then with the entire program of refinement and debugging, the bomber after 5 years cost 70 million dollars. US President Carter was at a loss and in 1977 year, in June, at a press conference he announced the termination of funding for the B-1 project.

But flight tests in-1 never stopped. The program is strongly supported Air Force leadership, it also made it possible to carry out a purge of the aircraft in a wind tunnel. Although officially in June, the program was closed in July 3-th prototype completed missile launch SRAM. According to official data the test program called VRE, it tested the third and fourth (final) prototypes.

5 years later, the program resumed Reagan. 2 81 October, US President announced a program of modernization of the strategic program and ATV LRCA. By LRCA Air Force was appointed in June-1V and prototype-1 renamed B-1A.

By outward appearances prototypes B and B 1A 1V quite similar, but at the same time completely different. In-1V designed with the expectation of a breakthrough of enemy air defenses at low altitudes at subsonic speeds. The maximum speed does not exceed the M = 1,25. In comparison with the B-1A his brother had a simplified design of air intakes (remove movable wedges), reduced ESR in the frontal plane, and radio-absorbing materials increased by 85%.

The maiden flight is already fully upgraded version of the B-1V in March 1983 years. It experienced a fourth prototype, which planned to make the standard for the series production of the program in-1, somewhat rebuilt and renamed the B-1V. The difference between the prototype and production aircraft was only in the design of the air intakes, the system interface of the wing to the fuselage and clean windows in the cockpit of the navigator.

Fully modified version of the B-1V rose into the sky in mid-October 1984 years. Rocket an SRAM with a first released in January 1987 year, in December, implemented pilot dropping bombs 56 svobodnopadayuschie practical. Practical use of cruise missiles carried on 9-28-m and m production aircraft. It is also the first series in 3-1V were certified on the use of nuclear bombs on unsupported V61 and V63. 59-th serial experienced explosive bombs Mk.82.

According to official statistics, every kind of test aircraft B-1V ended October 31 1985 years.

 

Design B-1

 

Based on the ergonomics have changed some parts of the structure. It was established 2 small window in the cockpit of the navigator-operator to eliminate claustrophobia. It was also modified the nose of the fuselage by installing a multi-mode radar AN / APQ-164A. Really change the system of emergency escape cabin. Zakabinnogo compartment increased. There was a possibility of suspension of air assets, intended to hit different types of goals. This was made possible thanks to the fact that frames the front compartment made mobile.

The plane made by the normal aerodynamic scheme. The design implemented integral arrangement which differs blending wing and fuselage. The integrated layout made it possible to increase the volume inside the airframe, reduce the surface area of ​​money and effective dissipation surface.

Installed on the wings and spoilers differentially deflected console stabilizer manage the roll.

The composition of materials for a glider: titanium alloy - 17,6%, aluminum alloy - 42,5%. The transverse box beam center section is a key element design that receives the load. Almost 80% made of titanium alloy using diffuse welding.

The fuselage is represented by a semi-monocoque. It consists of five main sections and has a high density of accommodation of spars and frames. The structural internal elements and the skin of the aircraft are made mainly of aluminum. Titan used in the area of ​​nacelle engines and in fireproof partitions. For the stability of the structure in a turbulent atmosphere, the established LARC system is responsible. It includes special sensors, which are placed at different points of the fuselage. With their help, the load of aerodynamic deviations is measured. Thanks to this system, the weight of the nose structure has decreased and the fatigue strength of the entire glider has increased.

Due to the fact that the wing is able to change its sweep, its carrier characteristics have increased equally well both in the low speed region and during the flight with large Mach numbers. When the sweep of the wings increases, the partially moving part is retracted into the center wing. At this point the plating is made of fiberglass. On B-1V, a simpler system of sliding gates and inflatable seals was used. At the heart of the construction of the movable consoles lie aluminum double-spoon coffers with ribs and milled spars. Also installed here are monolithic all-milled hull panels made of aluminum alloys.

The composition of the mechanization of each wing consists of seven sections of the slats with a deflection angle of 20° and odnoschelevymi shestisektsionnymi flaps.

The crew - 4 person: first and second pilots, two operators of offensive and defensive systems. They are housed in two pressurized cabins. Pilots are placed side by side: Left commander, co-pilot on the right. Right behind them is the second cabin with jobs navigators operators.
