Moskalyev DSB-LK bomber

[hesham]

Hi,

of course most of us know this aircraft,but I want to speak about it,
it can fly at 4.4 Mach.

"History
Following a task of the leadership of the VVS between 1957 and 1960 was developed a set of investigations aimed at exploring new versions of aircraft, seaplanes, ballistic missiles and jet aircraft configurations characterized by the possibility of supersonic speeds and long range. Almost all the major OKBs and institutions of the USSR linked to aeronautical development were connected to this work.

In the LKVVIA Mozhaiski since the end of the 50s and within the framework of development of the project called " Search for avenues for the development of supersonic seaplanes powerful " under the direction of AS Moscaliov and AI Smirnov, several interesting aircraft projects With this configuration. The main directions of work were directed to the development of bombers and jet planes like hydrocoses and amphibians of strategic character.

These projects were conceived in the take-off fretboard 150 - 500 tons with load capacities of 5 to 15 tons and speeds between Mach 2 and 4. The flight ceiling between 25 and 30 kilometers in height. This range of velocities involved the use of power plants consisting of turbojets with forcing chambers. Special emphasis was devoted to the composition of aircraft and issues related to the shape of the fuselage and wing. Multiple variants were studied and scale models were created to analyze their behavior.

As a result of the work of the LKVVIA confirmed the technical and technological possibility of developing aircraft of these characteristics in the late 1960s.

Development
The work of Moscaliov materialized in the conception of a bomber with flying wing scheme in whose development they also participated the TsAGI , the VVIA and the OKB-23 of the GKAT directed by Myasichev .
The project began in 1957 and by the end of 1959 a significant amount of information had been collected. These data were used for an evaluation of a possible structure, designed to cover the program specifications. A significant number of configurations were analyzed, including the use of conventional wings, a canard system with winged wings, configurations without glue, hang gliding and flying wing. All versions were powered with turbojets equipped with forcing or a combination of power plants including turbojets and stators. The definitive version, known as DSB-LK, according to the abbreviations of D alni S trateguicheski B ombardirovshik - L etayuche K rylo or long-range strategic bomber - flying wing, allowed to define more objectively the operational parameters for the flying wing. Using six turbojets with VK-15M forcing of 15800 kg forcing unit, this aircraft had to obtain a maximum speed of Mach 2.8 and a range of 16,800 km at cruising speed. A variant with stator reactors(ram jet) was also analyzed.

The fuselage had a triangular shape with rounded edges of attack, almost in the same configuration of the Sigma project of 1933 . The VK-15M engines were placed in two groups of three on both sides of the fuselage and on them were fixed the empennage with the steering rudders.

The delta wings had an angle of 72 ° at the leading edge and 42 ° at the trailing edge. The landing gear, tricycle type, featured four wheels on the front landing and eight on each of the main landers.

The crew of the airplane was composed by pilot, copilot and official of operation of the electronic equipment, located in a small cabin in l nose of the airplane.
Interior composition of the DSB-LK bomber showing the location of the weaponry. In the central part of the fuselage was located the armory of armament with a capacity of 5000 kg in different configurations of armament, including an FAB-5000 pump of that weight. It was conceived the use of new weapon systems composed of four air - to - air missiles with a range of up to 10 km and two turrets with high - rate firing guns. The DSB-LK also featured interference systems for enemy radars, a Rubin-1 radar system and modern flight control systems.
The study anticipated the possibility of replacing the D23 alloy, commonly used at the time for high-speed titanium aircraft, in order to lighten the aircraft and allow better operation at high temperatures.

The work of the LKVVIA Mozhaiski in relation to strategic supersonic aircraft was completed at the request of the VVS in 1960 , mainly due to problems related to budget cuts. Although the program never had practical realization, the results these investigations were highly valued by the direction of the Ministry of the Industry of Aviation and they were given to the OKB to be used theoretical base in its developments. This information would be used in the development of specific models such as the Tupolev Tu-22M . "

Almost same shape.
If vertical tail and engine nacelle side of this airplane tilts, and radar blocker are installed at front of the engine, reflection of a radar would be small. ;D

Apparently this was also called 'Darkstar'.
