Development

After the success of Sputnik 1, Korolev sent series of letters to the Central Committee of the Communist Party of the Soviet Union proposing a bold plan to send robotic spacecraft to Mars and Venus. As part of such plan, a fourth stage was needed to enhance the three stage R-7 rocket and enable it to send useful payloads to those high energy destinations. This fourth stage was called Block-E, and its development started during 1958. [3]

Korolev's OKB-1 design bureau initially competed two projects for the Block-E propulsion: 8K72, using the S.A. Kosberg's OKB-154 RD-0105, and the 8K73, using Glushko's OKB-456 RD-109 engine. Due to the complication of developing that latter, Kosberg got the contract. [4]

Since the February 20, 1958 order of development, it took nine months to develop the engine. It was done by using RD-0102 assemblies and combustion chamber. Fifty eight static tests were conducted with 27 engines. [5]

Between 1959 and 1960 the engine was modified to improve reliability for manned flight. [5] Thrust was also increased 2%, thanks to improved injection elements. It also introduced an innovation attributed to S.A. Kosbergs in its construction, that has been a staple of Soviet (and later Russian) engines. It used a corrugated metal construction for the cooling jackets, with the lower section of the nozzle lacking an external liner, to save weight. [6] This led to a 9.3% weight reduction even with the increased thrust. [1] This new version was christened as the RD-0109 and entered service on the December 22, 1960, launch of a (Vostok) spacecraft aboard a Vostok-K 8K72K. [1]

The RD-0109 is the basis for the Brazilian Space Agency L75 engine project. [7] [8]

History

While the first launches for Sputnik 1 satellites could be done with the two stage booster Sputnik, to achieve escape velocity required by the Luna programme, a third stage was needed. The task of developing the specified engine was entrusted to OKB-154 (KBKhA), which did the job in 9 months. The engine received intra name RO-5.

The first flight of a Luna 8K72, which included the new Block-E stage propelled by the RD-0105 was on September 23, 1958. It was supposed to launch the Luna E-1 No.1 probe, but ended 92 seconds after launch when the rocket broke up from longitudinal vibration, causing the strap-ons to separate from the vehicle, which then crashed downrange. [9] Neither was successful the second flight of a Luna 8K72 (October 11, 1958), which was to launch the Luna E-1 No.2 probe and ended 104 seconds after launch when the rocket again disintegrated from vibration. The third flight of a Luna 8K72 (December 4, 1958), which was to launch the Luna E-1 No.3 probe, also ended 245 seconds after launch when the Block-I core stage shut down from loss of engine lubricant.

On January 2, 1959, as part of the Luna 8K72's Block-E stage, the engine RD-0105 finally performed its first successful mission, the launch of Luna 1. It was also the first deep space engine ignition, the first spacecraft to reach escape velocity and, while the spacecraft missed the Moon with which it was supposed to crash, it became the first human made object to enter a heliocentric orbit. [10]

On September 14, 1959, the RD-0105 propelled Luna 2 towards the Moon. It was the first spacecraft to reach the surface of the Moon, and the first man-made object to land on another celestial body. It took with it a pennant with the State Emblem of the USSR. [10]

On August 19, 1960, the RD-0105 propelled Korabl-Sputnik 2 mission. It was the third Vostok spacecraft and the first spaceflight to send animals into orbit and return them safely back to Earth. [10]

On December 22, 1960, the RD-0109 had its first flight on a Vostok-K Block-E. Regrettably, the gas generator of the rocket third stage suffered a failure and the RD-0109 could not prove itself in flight. That chance came with the second Vostok-K launch, where the RD-0109 successfully launched the Korabl-Sputnik 4 mission to orbit.

On April 12, 1961, the RD-0109, as part of the Block-E stage of the Vostok-K 8K72K rocket, propelled the historic Vostok 1 to orbit making Yuri Gagarin the first human to go to outer space and the first to orbit the Earth. [10]

On June 16, 1963, the RD-0109 propelled the Vostok 6 making Valentina V. Tereshkova the first woman to orbit Earth. [10]

Improvement and modifications required to comply with the man rating of the RD-0105 led it to have two versions:

Vostok 1 First human spaceflight in history

Vostok 1 was the first spaceflight of the Vostok programme and the first human orbital spaceflight in history. The Vostok 3KA space capsule was launched from Baikonur Cosmodrome on April 12, 1961, with Soviet cosmonaut Yuri Gagarin aboard, making him the first human to reach orbital velocity around the Earth and to complete a full orbit around the Earth.

Spacecraft Vehicle or machine designed to fly in space

A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle.

Chemical Automatics Design Bureau Russian rocket engine manufacturer


Chemical Automatics Design Bureau (CADB), also KB Khimavtomatika, is a Russian design bureau founded by the NKAP in 1941 and led by Semyon Kosberg until his death in 1965. Its origin dates back to a 1940 Moscow carburetor factory, evacuated to Berdsk in 1941, and then relocated to Voronezh city in 1945, where it now operates. Originally designated OKB-296 and tasked to develop fuel equipment for aviation engines, it was redesignated OKB-154 in 1946.

Luna (rocket)

The Luna 8K72 vehicles were carrier rockets used by the Soviet Union for nine space probe launch attempts in the Luna programme between 23 September 1958 and 16 April 1960. Like many other Soviet launchers of that era the Luna 8K72 vehicles were derived from the R-7 Semyorka design, part of the R-7, which was also the basis for the Vostok and modern Soyuz rocket.

The Vostok-L, GRAU index 8K72 was a rocket used by the Soviet Union to conduct several early tests of the Vostok spacecraft. It was derived from the Luna rocket, with a slightly enlarged second stage to accommodate the larger payload, and was a member of the Vostok family of rockets. It used the new 8K74 core instead of the 8K71 used on the original R-7 ICBM and the Luna boosters. The 8K74, first tested in December 1959, had a number of technical improvements to increase reliability and make servicing easier. Four launches were conducted between 15 May and 1 December 1960, three of which successfully reached orbit.

The Vostok-K, GRAU index 8K72K was an expendable carrier rocket used by the Soviet Union for thirteen launches between 1960 and 1964, six of which were manned. It was derived from the earlier Vostok-L; however, it featured uprated engines to improve performance, and enlarge its payload capacity. It was a member of the Vostok family of rockets.
