The world's first supersonic bomber - B-58

B-58 Hustler (Hustler - pickpocket, Dodger) - the world's first long-range bomber, capable of flying at supersonic speeds. He was in service with the US Air Force in 1960-s. At the time of its creation, the maximum speed of the bomber (M = 2) corresponded to the speed of the fastest fighters of its period. At the same time, due to a number of existing drawbacks, its operation was relatively short, but the bomber still managed to occupy a prominent place in stories world bomber aviation. From 1956 to 1962, 116 aircraft of this type were manufactured in the United States.

In March 1949, the United States Air Force Aeronautical Research and Development Group (ARDC) issued requirements for the development of a supersonic long-range bomber. The design of the new machine was taken up by 2-e famous companies: Boeing and Convair, which are the main manufacturers of aircraft for the needs of the US Air Force. The task was quite difficult. Only by 1951, the companies managed to complete the refinement of their technical projects. 1 February 1952 of the year the customer sent the company a collection of updated TTH, presented to the new long-range supersonic bomber. Based on the requirements of the documentation, it was necessary to develop and build a bomber capable of flying in any weather conditions at low and high altitudes with a speed that would exceed the speed of sound. The range of the aircraft was determined at the level of 4 thousands of nautical miles, bomb load - 5 tons. In addition, the new bomber was supposed to be a multi-purpose machine. The creation of the first aircraft was given no more than 5 years.

Taking into account these wishes, the engineers of the two companies finalized their XB-58 and XB-59 projects and submitted them to the competition. Comparison of the two presented aircraft engaged in the Air Force Research Center. As a result of the comparison, the victory was gained by the aircraft produced by the company Konver. 10 December 1952, the aircraft received its official designation B-58, in the same year, Convair managed to get an order for the release of 18 data machines.
The world's first supersonic bomber - B-58

The B-58 bomber was designed in a tailless pattern and had a mid-winged delta wing with large sweep angles. The shape of the aircraft fuselage was chosen taking into account the area rule. About 15% of the surface of the aircraft was covered with a stainless steel shell, which very well prevented the heating of the bomber. Under the plane of each wing on one pylon was suspended 2 engine J57-P-15. However, this layout of the power plant did not last long. Soon it was found that because of the danger of overheating of the lower surface of the wing in the places of installation of internal engines, there is a real danger of fuel ignition in the wing tanks of the aircraft. Quite quickly, it was decided to install a turbofan on individual pylons. On the B-58 aircraft, rather unusual main landing gear was used, which had 4 pairs of wheels on each rack. The height of the landing gear was a few meters, which was due to the presence of a sufficiently large landing angle for the bomber, as well as the requirement to ensure free suspension of weapons, as the plane did not have its own bomb bay.

The crew of the long-range bomber B-58 consisted of 3-man - pilot, navigator-scorer, radio operator, operator of defensive systems. Initially, they were located in separate cabins equipped with ejection seats, but subsequently they were placed in a single sealed compartment. Each of the three workplaces had an individual opaque hatch, which was opened with the help of hydraulics. The operator and navigator compartments had 2 small rectangular windows in the sides, which were made so that the crew did not feel claustrophobic. However, according to the pilots themselves, there was simply no time for such nonsense, as well as for rest, during the flight: the equipment of the bomber required constant attention from the crew.

The B-58 was the first serial supersonic bomber in aviation history and therefore contained a large number of innovations. His creation was an attempt to reverse the trend established in those years, which led to an increase in the mass of aircraft to perform the required tasks. The relatively small size of the bomber made it sufficiently imperceptible - its EPR - effective dispersion surface (the most significant of the parameters when detecting the radar aircraft) ranged from 1 / 10 to 1 / 30 from the EPR of a B-52 bomber depending on the angle in space.

The design of the bomber differed great complexity and novelty. The hull and the wing were a single whole: the fuselage frames were smoothly transformed into the wing spars. During a long flight at a supersonic speed on the plane, in addition to the air velocity, there are acoustic and thermal loads. In order to ensure acceptable rigidity and structural strength, the wing was manufactured as much as an 33-spar. In this case, the step between the elements of this kind of "skeleton" was equal to the entire 280-330 mm. The front edge of the wing had a 60-degree sweep. She was well developed on previous aircraft company Convair.

In fact, the Hustler wing was a F-102 interceptor wing, which was proportionally increased. At the same time, due to the relatively small thickness of the wing profile, the mounting of the engine pylons, the layout of the power elements and the landing gear were a serious problem. Simultaneously, the wing of the bomber did not have takeoff and landing mechanization. To increase stability and to slightly improve its performance at high angles of attack, which were common to all tailless aircraft during landing, the front edge of the wing was made with a twist.

About 80% of the entire aircraft skin were glued laminated panels of 2-x duralumin sheets having a thickness from 0,25 to 1 mm., Which had a layer of cellular filler. In the places that were most exposed to heat, the “cells” were made of duralumin, and in the rest of the places - of fiberglass, which also had a high coefficient of thermal insulation. The panels were assembled using rubber-phenolic and epoxy-phenolic glue; very expensive new technologies were used to form them. Bomber B-58 Hustler had a very frequent and powerful power set, which was similar to the ship. The skin was attached to the “skeleton” of the aircraft using titanium and steel rivets, which provided the rigidity and smoothness of the external surfaces required for supersonic flights. It is worth noting that the large amount of work done by the designers gave its fruits, the Hustler glider turned out to be a record (even today) easy with a high level of rigidity.

B-58 bomber was almost always used with an external suspension under the fuselage. In this case, the aircraft could use: MC-1C - a guided missile equipped with an inertial guidance system and a fluid engine. The rocket could be equipped with either a warhead with a charge of conventional explosives or a nuclear warhead. The range of the launch of the MC-1C rocket directly depended on the flight altitude (should have been from 10 668 to 18 288 meters at the moment of UR separation from the aircraft) and ranged from 16 to 257 km. To launch such missiles, the crew had to raise a bomber to a great height, where it became a good target for enemy air defense systems. MB-1C - free-fall bomb or ballast to improve the flight characteristics of the aircraft. Usually used in the first years of operation B-58.

Also, the aircraft could use TCP - "two-component container." One of its parts was filled with fuel, and the other contained the Mk53 bomb. There were 2 variations of these containers: BLU2 / B1 and BLU2 / B2, which differed in size and weight. In addition, the aircraft could be the carrier of the megaton class 4-x Mk43 nuclear bombs. Hustler could also carry a container with reconnaissance equipment - MC-1. For the defense of the rear hemisphere of the aircraft on it in the rear fuselage was mounted 6 stolnaya 20 gun M61 Vulcan with remote control. In addition, the bomber was equipped with means of electronic countermeasures controlled arms the adversary. All the functions of managing defensive weapons systems were performed by a radio operator.

Due to the difficulty of operating the bomber, very high demands were placed on the pilots and on the ground staff. The combatant pilots were selected only on the personal recommendation of the commander of the wing and should have had at least 1000 hours of flight time on jet planes. In this case, half of the raid was to occur on flights as the commander of a multi-engine jet aircraft crew. In addition, due to the lack of free space in the cockpit, the pilots had to meet the requirements for weight and height. Ground staff to service the B-58 Hustler was also selected only from a number of very high-class specialists.

In total, the production time was made 116 aircraft B-58, which in combat units operated until the end of the year 1969. It is worth noting that the pilots did not particularly like these planes. During operation, for various reasons, 26 machines were lost (22,4% of all manufactured), which is a large enough indicator of peacetime losses. One of the bombers crashed in 1961 during a demonstration flight at the Paris Air Show. Despite the fact that in the course of its operation, work was constantly carried out on upgrading equipment and systems, the machine quickly became obsolete and, in the end, was removed from service with the US Air Force and deposited.

    The B-58 is built on German developments in the field of aerodynamics, Americans have suffered a lot with him. As far as I know, this was the most expensive program in the history of the US Air Force (before the advent of the B-2). But nothing but a high accident rate and danger for the crew did not provide ..

      The most expensive program in the history of the US Air Force, as I recall, is the famous Valkyrie. Somewhere it was written that if this plane would be poured out of pure gold, it would still be cheaper ...

        The Valkyrie is an aircraft that was not mass-produced as the T-4 "weaving".
        And the B-58 program cost 2,3 billion at 60 years old when the dollar was real ... And not a candy wrapper ...

    Considering that it was the first supersonic bomber, and when they made a scout out of it, it spoiled the blood of our air defense. And the fate of the first supersonic strategic planes is very similar to that of ours and those of the "adversaries." We also had an M-50, then worked as a tanker

    The flying yabuldovina turned out. But the technology with it was raised to a new level ... It's like about the MiG-23,25, Tu-160, I'm talking about technology. To read how the central power unit or tank caisson was cooked in a special chamber in a special environment , the hairs on the head stand up. God grant that all this should not be lost, but rather multiplied.

    In 1958, the decision is made to exempt OKB-23 from presenting M-50 for state tests and to use two M-50 under construction with VD-7 and M16-17 engines for testing the future M-52. Around the same time, the Fifty-dozen tanker project was proposed for refueling the combat vehicle at supersonic speeds and heights of at least 10000 m. The M-50 developed the M-50LL flying laboratory for research of the turbofan engines created based on the NK-12 TVD and the TS-12M turbo starter, and the M-51 unmanned carrier for the delivery of a nuclear weapon. In May, the 1959 began the taxiing of the bomber.

    I didn’t hear anything about guided weapons on the B-58. There were no projects, but they didn’t get out of the project stages. This was how this composite plane flew, the main purpose of which was to convey a free-falling YaB that was lying in the container with the fuel. By the way, operation without a container was not recommended, misalignment and the plane stupidly stood on its tail.

    I found a "controllable bomb container MA-1S, which represented a cruise missile weighing 12295 kg with a launch range of 260 km, work on it began in 1953. In the first half of 1957, they were discontinued for a number of reasons. Modernization projects for the B-58 aircraft that were supposed to receive missile weapons were also not At the beginning of the 60s, some of the MV-1S containers were converted into the LA-1 version, the planned AFA KA-56A was installed in place of the warhead, at the end of 63g, 45 V-58s were able to be equipped with this suspension. there are nerves in this role they could not wag.
    About the M-50. By the Decree of the Council of Ministers of the USSR dated July 31.07.58, 50, both copies of the M-52 were not transferred to the GI, but used in the interests of developing the M-50. In total, the M-19A made 52 flights, after which it stood idle for several years and was transferred to the Air Force Museum in Monino. The doubler and the almost completed M-XNUMX were sent to scrap.

    Have you heard the news? The Russian authorities are already insolent in the end. They made this database
    zipurl. ws / sngbaza where you can find information about any resident of Russia, Ukraine and other CIS countries. I was really very surprised that there were a lot of interesting things about me (addresses, phone numbers, even my photos of a different nature) - I wonder where they dug it up. In general, there are also good sides - this information can be deleted from the site.
    I advise you to hurry, you never know how to fumble there ...
