Black Arrow

Black Arrow, officially capitalised BLACK ARROW,[3] was a British satellite carrier rocket. Developed during the 1960s, it was used for four launches between 1969 and 1971. Its final flight was the first and only successful orbital launch to be conducted by the United Kingdom, and placed the Prospero satellite into low Earth orbit.[2]

Black Arrow originated from studies by the Royal Aircraft Establishment for carrier rockets based on the Black Knight rocket,[4] with the project being authorised in 1964. It was initially developed by Saunders-Roe, and later Westland Aircraft as the result of a merger.

Black Arrow was a three-stage rocket, fuelled by RP-1 paraffin (kerosene) and high test peroxide, a concentrated form of hydrogen peroxide (85% hydrogen peroxide + 15% water).[5] It was retired after only four launches in favour of using American Scout rockets, which the Ministry of Defence calculated to be cheaper than maintaining the Black Arrow programme.[6]

Black Arrow originated from a Royal Aircraft Establishment proposal for a rocket capable of placing a 317-pound (144 kg) payload into low Earth orbit, in order to test systems designed for larger spacecraft. In the autumn of 1964, the programme was authorised by Conservative Aviation Minister Julian Amery. Then, following a general election in October, the incoming Labour government put the project on hold to reduce expenditure.[7] Following another election, the government approved the continuation of the programme with several modifications, including the reduction of the test programme from five to three launches. The first launch was set for 1968.[8]

Most of the technology and systems used on Black Arrow had already been developed or flight-proven on the Black Knight rocket, or the Blue Steel missile.[4] Black Arrow was designed to reuse as much technology from the earlier programmes as possible in order to reduce costs, and simplify the development process.[2] Many senior staff of the Black Knight programme transferred directly to Black Arrow, including the Chief Missile Scientist, Roy Dommett, the Chief Design Engineer, Ray Wheeler and the Deputy Chief Engineer, John Underwood.[9]

Initial development was conducted by Saunders-Roe, which merged into Westland Aircraft in 1964. Westland was subsequently the prime contractor for the Black Arrow, and assembled the first and second stages at East Cowes on the Isle of Wight. Bristol Siddeley produced the first and second stage engines at a factory in Ansty, Warwickshire. The engines were test fired at the factory before being shipped to the Isle of Wight, where they were integrated into the rocket and the first stage engines were fired again at High Down.[10] Bristol Aerojet produced the third stage in Somerset, while the Explosives Research and Development Establishment produced its solid propellant in Waltham Abbey, Essex.[4] The Rocket Propulsion Establishment, based in Westcott, Buckinghamshire, was responsible for the design and integration of the stage.[4]

The name Black Arrow came from the Ministry of Supply policy of assigning designations consisting of a colour and a noun, unofficially known as Rainbow Codes, to research programmes conducted by the Armed Forces.[3]

The first and second stages of the Black Arrow were fuelled by RP-1 paraffin (kerosene), burnt using high test peroxide as an oxidiser.[5] Due to the optimum mixture ratio being about 7, a larger oxidiser tank was required compared to many contemporary launch systems.[11] The oxidiser tanks were located below the fuel tanks, following the practice of putting the more dense propellant at bottom in order to lower the centre of gravity and make the rocket easier to control.[4] This arrangement had been pioneered by Germany and the United States, whereas the Soviet Union had placed oxidiser tanks above fuel tanks, making it easier for the lower tank to be filled first.[12]

Thrust vectoring was used to provide attitude control on the first two stages.[4] The eight first stage combustion chambers were arranged in pairs which could gimbal either way along one axis.[4] Two of the pairs were arranged perpendicular to the other two, and when all four pairs were used together, they provided roll, pitch and yaw control.[4] The second stage had two combustion chambers, which could gimbal along two axes, providing the same level of control. During a coast phase after second stage cut-off, the rocket was controlled by a reaction control system.[4] The third stage did not have an attitude control system, and was instead spin-stabilised.[2]

The first stage was powered by a single Gamma 8 engine, which burned for 127 seconds.[2] The Gamma 8 was an eight-chamber engine, derived from the Gamma 301 engine used on the Black Knight. It was 6.9 metres (23 ft) long, and had a diameter of 2 metres (6 ft 7 in), the same diameter as the French Coralie.[2] Coralie was used as the second stage of the Europa rocket, and the decision to give Black Arrow the same diameter as Coralie was taken in order to make it compatible with Blue Streak, which was used as the first stage of Europa.[2] This would have allowed Black Arrow's payload capacity to have been increased, and would also have allowed Britain to use the first stage of Black Arrow as a backup to the Coralie.[13] For this reason, all dimensions in the original specification were given in imperial units except the first stage diameter, which was given in metres.[2]

The first and second stages were connected by an interstage structure containing four Siskin IB separation and ullage motors, which separated and ignited seven seconds after the first stage had cut off.[4][14] The interstage separated from the second stage six seconds later. The second stage, which was 2.9 metres (9 ft 6 in) long and measured 1.37 metres (4 ft 6 in) in diameter, was powered by a two-chamber Gamma 2 engine[15] which ignited shortly after the separation motors, and continued to burn for 123 seconds.[2] Three minutes after launch, during the second stage burn, the payload fairing separated.[2]

About 257 seconds into the flight, the second stage cut off, and the rocket entered a coast phase to apogee.[2] Immediately after cut-off, the second stage attitude control system was pressurised. During the coast the correct orientation for third stage separation was maintained by means of the attitude control system.[2] Towards the end of the coast period, the third stage was spun up to a rate of 3 hertz (180 rpm) by means of six Imp rockets.[2] Five seconds later, the third stage separated,[4] and following ten more seconds of coasting, it ignited. The third stage was a Waxwing solid rocket motor, which burned for 55 seconds.[2]

Just over a minute after the third stage had burned out, the payload was released, and gas generators were used to push the spacecraft and spent upper stage apart.[2] The delay between burnout and separation was intended to reduce the risk of recontact between the upper stage and payload due to residual thrust. Despite this, following spacecraft separation on the R3 launch, the upper stage collided with the Prospero satellite,[2] damaging one of the spacecraft's communications antennae;[16] however the spacecraft was still able to successfully complete its mission.[16] On the R3 launch, the ascent took 710 seconds (11.8 min) from liftoff to spacecraft separation.[2]

Although none were ever built, several derivatives of Black Arrow were also proposed, as ways of increasing its payload capacity.[2] One proposal added eight Raven solid rocket motors from the Skylark programme to the first stage as booster rockets.[4] Another suggestion was to mount the entire rocket atop a Blue Streak missile,[2] while a third proposal involved replacing the Gamma engines with the more powerful Larch.[4]

Four Black Arrows were launched between 1969 and 1971. The first two launches were demonstration flights, with battleship third stages and a boilerplate payload. On the first flight an electrical fault caused a pair of first stage combustion chambers to pivot back and forth.[17] Before it cleared the launch pad, the rocket was rolling erratically, and about a minute later it began to disintegrate. After the first stage engine failed, and the rocket began to fall back to earth, it was destroyed by range safety.[18] The second launch was successful. The first all-up launch on 2 September 1970 was the third launch of the Black Arrow, and Britain's first attempt to launch a satellite. The launch failed due to a leak in the second stage oxidiser pressurisation system, which caused it to cut out early. The third stage fired, but the rocket did not reach orbit, and re-entered over the Gulf of Carpentaria.[19] The fourth launch successfully orbited the Prospero (before the R2 mission, it was named Puck) satellite, making the United Kingdom the sixth nation to place a satellite into orbit by means of an indigenously developed carrier rocket. The satellite, also known as X-3, was named Prospero after the character Prospero in Shakespeare's The Tempest. The name was chosen as a reference to events in the play, in which Prospero, a sorcerer, gives up his powers.[20] Prior to the cancellation of the Black Arrow programme, the satellite was to be named after Puck from A Midsummer Night's Dream.[5]

All four launches were conducted from Launch Area 5B at the Woomera Prohibited Area in Australia, which had previously been used as a test site for the Black Knight rocket. During the development programme, launch sites in Barbados, Uist and Norfolk were also considered.[2] The launch sites at Uist and Norfolk were rejected because the former was too remote, while there was a risk that a rocket launched from the latter might drop spent stages on an oil rig in the North Sea.[21]

The Minister of State for Trade and Industry, Frederick Corfield, announced the cancellation of the Black Arrow project in the House of Commons on 29 July 1971. As the R3 rocket had already been shipped to the launch site, the second stage having arrived three days earlier, permission was given for it to be launched.[2]

The programme was cancelled on economic grounds, as the Ministry of Defence decided that it would be cheaper to use the American Scout rocket, which had a similar payload capacity, for future launches.[6] Prior to the cancellation of Black Arrow, NASA had offered to launch British payloads for free; however, this offer was withdrawn following the decision to cancel Black Arrow.[2]

The final Black Arrow to be completed was R4, which did not fly, and is preserved in the Science Museum, London, along with the flight spare for the Prospero satellite.[23] A replica of the Black Arrow rocket stands in the Rocket Park at Woomera. In addition, the remains of the first stage of Black Arrow R3 were recovered from the Anna Creek cattle station and were displayed in the William Creek Memorial Park.[24] They have now been returned to the United Kingdom, and are due to be displayed in Penicuik, Scotland, by the end of March 2019.[25]

The launch facilities at Woomera were demolished within a year of the final flight,[4] and half of the engineers who had worked on the programme were laid off.[18] The X-4 satellite, which had been manifested for launch by Black Arrow R4, was eventually launched on 9 March 1974, by an American Scout D-1 rocket flying from Space Launch Complex 5 at the Vandenberg Air Force Base in California.[26]

As of 2018, the United Kingdom is the only country to have successfully developed and then abandoned a satellite launch capability.[27] All other countries that have developed such a capability have retained it either through their own space programme or, in the case of France, through its involvement in the Ariane programme.[27]

Black Arrow (serial)

Black Arrow (1944) is a Columbia film serial. It was the twenty-fourth of the fifty-seven serials released by Columbia.

Blue Streak (missile)

The de Havilland Propellers Blue Streak was a British medium-range ballistic missile (MRBM), and later the first stage of the Europa satellite launch vehicle. Blue Streak was cancelled without entering full production.The project was intended to maintain an independent British nuclear deterrent, replacing the V bomber fleet which would become obsolete by 1965. The operational requirement for the missile was issued in 1955 and the design was complete by 1957. During development it became clear that the missile system was too expensive and too vulnerable to a pre-emptive strike. The missile project was cancelled in 1960, with US-led Skybolt the preferred replacement.

Partly to avoid political embarrassment from the cancellation, the UK Government proposed that the rocket be used as the first stage of a civilian satellite launcher called Black Prince. As the cost was thought to be too great for the UK alone international collaboration was sought. This led to the formation of the European Launcher Development Organisation (ELDO), with Blue Streak used as the first stage of a carrier rocket named Europa.

Europa was tested at Woomera Test Range, Australia, and later at Kourou in French Guiana. Following launch failures, the ELDO project was cancelled in 1972 and development of Blue Streak was halted.

Bristol Siddeley Gamma

The Armstrong Siddeley, later Bristol Siddeley Gamma was a family of rocket engines used in British rocketry, including the Black Knight and Black Arrow launch vehicles. They burned kerosene fuel and hydrogen peroxide. Their construction was based on a common combustion chamber design, used either singly or in clusters of up to eight.

They were developed by Armstrong Siddeley in Coventry, which later became Bristol Siddeley in 1959, and finally Rolls-Royce in 1966.Engine static testing was carried out at High Down Rocket Test Site, near The Needles on the Isle of Wight (50°39′38.90″N 1°34′38.25″W). (Spadeadam in Cumbria wasn't used for testing until Blue Streak, after Gamma).

Europa (rocket)

The Europa rocket was an early expendable launch system of the European Launcher Development Organisation (ELDO), which was the precursor to the European Space Agency (ESA). It was developed with the aim to delivering space access technology, and more specifically to facilitate the deployment of European-wide telecommunication and meteorological satellites into orbit.

The Blue Streak missile predated the Europa programme, having originally been developed by Britain primarily for military purposes, however it was cancelled in 1960. Efforts to repurpose the Blue Streak, such as the studied Black Prince expendable launch system, eventually cumulated in the multinational Europa programme.

Workshare on the programme was shared between the various members of the ELDO based upon their financial contributions. The Europa launcher itself primarily consisted of the Blue Streak, Coralie, and Astris rocket stages.The programme proceeded to perform multiple test launches, however these frequently resulted in partial failures. In addition, Britain decided to pull out of the ELDO organisation, and thus Europa, to instead focus on the rival British Black Arrow launcher instead. This led to the replacement of the Blue Streak by the French-built Diamant section. However, confidence in the programme had diminished due to the poor reliability figures, and this led to its termination. While Europa was ultimately cancelled, the ambition for such a launcher was still present and supported by the majority of ELDO members and, following its reformation into the ESA in 1974, the agency proceeded to develop the Ariane family of launchers, would which prove to be a commercial success with hundreds of launches performed.

Larch (rocket engine)

The Larch was a family of rocket engine intended as an upgrade to Black Arrow launch vehicles. They were manufactured by Rolls Royce between 1965–1971. They burned kerosene fuel and hydrogen peroxide.

Middle-earth weapons and armour

Weapons and armour of Middle-earth are found in J. R. R. Tolkien's Middle-earth fantasy writings, such as The Hobbit, The Lord of the Rings and The Silmarillion. Wars and battles are featured in much of Tolkien's writings, and weapons and armour are often given special attention.Tolkien modelled his fictional warfare on the Ancient and Early Middle periods of history. His depiction of weapons and armour particularly reflect the Northern European culture of Beowulf, the Norse sagas and similar works. Tolkien established this relationship in The Fall of Gondolin, the first story in his legendarium to be written. In this story, the Elves of Gondolin use mail armour, swords, shields, spears, axes and bows, which is consistent with Northern European warfare. In Tolkien's writings, these kinds of weapons and armour are used by his fictional races, including Elves, Dwarves, Men, Hobbits, and Orcs. Like his sources Tolkien sometimes uses the motif of ceremonial runic inscriptions in his fictional items of warfare to show these items are magical and have their own history.

Operation Black Arrow

Operation Black Arrow (Hebrew: מבצע חץ שחור‎ Mivtza Ḥetz Shaḥor) was an Israeli military operation carried out in Gaza (while under Egyptian control) on 28 February 1955. The operation targeted the Egyptian Army. Thirty-eight Egyptian soldiers were killed during the operation as were eight Israelis.

Orba (satellite)

Orba, also known as X-2, was intended to be the first satellite launched by a British rocket. It was launched at 00:34 GMT on 2 September 1970, atop a Black Arrow rocket from Launch Area 5B at Woomera, but failed to reach orbit after the second stage of the carrier rocket shut down 13 seconds early. Orba was built from spare parts due to funding restrictions, and was to have been used to measure upper atmosphere density by monitoring the decay of its orbit.

Prospero (satellite)

The Prospero satellite, also known as the X-3, was launched by the United Kingdom in 1971. It was designed to undertake a series of experiments to study the effects of space environment on communications satellites and remained operational until 1973, after which it was contacted annually for over 25 years. Although Prospero was the first British satellite to have been launched successfully by a British rocket, the first British satellite placed in orbit was Ariel 1, launched in April 1962 on a U.S. rocket.

Prospero has the COSPAR (NSSC ID) designation 1971-093A and the US Space Command satellite catalogue number 05580.

The Black Arrow (film)

The Black Arrow is a 1948 American swashbuckler film. directed by Gordon Douglas and starring Louis Hayward and Janet Blair. It is an adaptation of the 1888 novel of the same title by Robert Louis Stevenson.

USS Black Arrow

USS Black Arrow (ID-1534) was a troop transport commissioned in 1919 to assist in the post-World War I repatriation of U.S. troops from France. Black Arrow was originally SS Rhaetia, a passenger-cargo ship built in Germany in 1904–05 for the Hamburg-America Line. From 1905 to 1914, Rhaetia operated primarily between Hamburg, Germany and South America, though she was also intermittently employed as an immigrant ship to the United States. With the outbreak of World War I in August 1914, Rhaetia was interned at Philadelphia.

With the entry of the United States into the war in April 1917, Rhaetia and other German ships interned in U.S. ports were seized by the U.S. government for possible use in the war effort. After repairs, the former Rhaetia went into service with the U.S. Army as a general transport under the names USAT Black Hawk and later USAT Black Arrow, making five round trips between the United States and France from June 1917 to the end of the war in November. The ship was then converted into a troop transport in order to assist with the repatriation of U.S. troops from France. Commissioned into the U.S. Navy as USS Black Arrow (ID-1534), the ship subsequently made three round trips to France from April to July 1919, returning a total of 4,759 troops to the United States, before decommissioning in August.

Reverting to the name SS Black Arrow following her naval decommission, the vessel was given a refit before being chartered by the United States Shipping Board to the American Line. She then recommenced merchant service as a passenger-cargo ship, inaugurating a new service from New York to Black Sea and Near East ports, and in December 1919 became the first ship to return to the United States from Constantinople since the outbreak of the war. After only one more voyage to the Near East however, the ship was given another refit and chartered to the Ward Line for service between New York and Spain.

In August 1921, on her fourth voyage to Spain, Black Arrow ran aground off the Spanish coast at Cape Vilan. Refloated, she was returned to New York in November but saw no further service. After being laid up for an extended period, she was scrapped at New Jersey in late 1924.

Waxwing (rocket motor)

Waxwing was a British solid rocket motor used for apogee kick as the 3rd (upper) stage of the Black Arrow satellite launch vehicles.

Waxwing was used to successfully place the Prospero X-3 satellite into low Earth orbit on 28 October 1971, Britain's only satellite launch on an indigenously-developed launch vehicle.

Another use of Waxwing was to increase the velocity of test re-entry vehicles on Black Knight during tests for the Blue Streak missile.

Woomera Launch Area 5

Launch Area 5 (LA5) is an operational site at the RAAF Woomera Test Range which forms the primary operational capability of the Woomera Range Complex. Originally LA5 was a rocket launch site which supported a number of British experimental launches, including the United Kingdom's first, and as of 2019 only, satellite launch. It consisted of three separate launch pads, which supported 22 Black Knight sounding rocket launches, and four Black Arrow carrier rocket launches. Of the four Black Arrow launches, two were orbital launches, the first of which, on 2 September 1970, failed, and the second, on 28 October 1971, succeeded, placing the Prospero satellite into low Earth orbit.

Zastava M93 Black Arrow

The M93 Black Arrow (Serbian: М93 „црна стрела“) is a 12.7mm or .50 caliber anti-materiel rifle developed and manufactured by Zastava Arms.
