ЦитироватьСМИ: Индия до конца лета испытает прототип ракеты-носителя многоразового использования
       
 Индийская организация космических исследований (ИСРО) проведет до конца лета испытания прототипа ракеты-носителя многоразового использования собственной разработки, передает ТАСС. Об этом журналистам сообщил директор соответствующей программы в ИСРО М. Чандрадатхан.
 
 "В настоящий момент идет подготовка к запуску в конце июля - начале августа", - приводит его слова информационный портал "Зи ньюс".
 
 Как сообщили ранее корр. ТАСС в ИСРО, прототип ракеты-носителя массой 1,5 тонны будет поднят на высоту в 70 км при помощи твердотопливного ускорителя и достигнет скорости до 5 Маха (в 5 раз выше скорости звука), после чего приводнится в море.
 
 В ходе испытаний ученые рассчитывают проверить теплозащитную систему, систему управления, аэродинамические характеристики аппарата на гиперзвуковой скорости. Сроки конструирования ракеты-носителя и оценочную стоимость проекта Индийская организация космических исследований уточнять не стала. Пуск должен состояться с единственного в стране космодрома на острове Шрихарикота вблизи побережья штата Андхра-Прадеш.

ЦитироватьPlan to largely privatize PSLV operations by 2020: Isro chief
Srinivas Laxman | TNN | Feb 15, 2016, 09.15 AM IST

Isro's PSLV-C31 carrying IRNSS-1E takes off during its launch from Satish Dhawan Space Center in Sriharikota

MUMBAI: In a revolutionary change in India's space scenario, the operation of Isro's workhorse — the four-stage Polar Satellite Launch Vehicle (PSLV) — will be largely privatized in four years, Isro chairman AS Kiran Kumar has told TOI.
 
 The Isro chief said that once the plan materializes, the integration and launch of the rocket will be handled by an industrial consortium through the commercial arm of Isro, Antrix Corporation.

 "This will be discussed with industry leaders at the Make In India week. Tentatively, we plan to implement it in 2020," he said.
 
 He explained that the advantage of largely privatizing the PSLV operations is to boost capacity and consequently increase the rate of launches from 12 to 18 annually. If the plan takes off, it will be akin to US's United Launch Alliance (ULA), a joint venture between Lockheed Martin and Boeing Company formed in 2006, to provide cost-efficient access to space for US missions.
 
 The PSLV , first launched in September 1993, has notched up 33 missions to date. Except for one failure during its maiden flight in 1993, the rest were successful, earning it global recognition as one of the most successful rockets.

Amongst others, he spoke of issues with ignition in the gas generator section at low mixture ratio, and combustion instability problems of the new design of semi-cryo engine under development now. He emphasized that more theoretical studies were needed in respect of vacuum ignition of steering engine, ignition of gas generator at low mixture ratio, saw tooth pattern observed in the main thrust chamber after hot test and combustion instability modelling of semi-cryogenic engines for providing strength in making critical decisions in short duration high risk development of these engines.

ЦитироватьFrance and India to study future rocket designs, including reusable vehicles

India's PSLV rocket lifts off in June 2014 carrying Airbus Defence and Space's Spot 7 Earth observation satellite, two years after the launch of the identical Spot 6. India's PSLV has increased its annual launch rate, making it a serious competitor to Europe's Vega and Soyuz vehicles. The French and Indian space agencies are nonetheless working together on future launcher studies, with France helping India transfer PSLV production from India's ISRO agency to industry.
 
PARIS — The French and Indian space agencies on Jan. 9 agreed to create a joint working group to study future launcher technologies, especially those applicable to full or partial rocket reusability.
The agreement is the latest in a long history of space-technology cooperation between the two countries. Excluding European nations and the 22-nation European Space Agency (ESA), India is the second-largest partner for the French space agency, CNES, after NASA, when measured by investment volume.
But past dealings have mainly focused on Earth observation and science, not launch vehicles, which France views as the innermost sanctum of its space effort.
And while the Indian Space Research Organization (ISRO) has been viewed with mainly benevolent neglect by CNES's launcher directorate, the success of India's PSLV medium-lift rocket in winning international business from owners of small satellites has not gone unnoticed.
Arianespace Chief Executive Stephane Israel, in a Jan. 4 briefing here, heaped praise on India's PSLV rocket, which he noted has even won business from French companies. Airbus Defence and Space launched its Spot 6 and Spot 7 satellites aboard separate PSLV rockets.

India's work on the more-powerful GSLV rocket has suffered multiple delays but now appears on track to take at least a piece of India's domestic satellite business within five years, if not less.
On reusability, Europe so far has seen no urgency in copying U.S.-based SpaceX, whose policy of returning to Earth its Falcon 9 rocket's first stage has caused concerns among French politicians but not yet resulted in a major investment.
Europe's launch sector uncertain of economic model for reusable rockets
French and European launch-industry officials remain uncertain of whether the kind of reusability envisioned by SpaceX is feasible in Europe given the likely annual launch pace.
Refurbishing and relaunching a rocket engine or stage would reduce the annual production volume and cause an increase in per-unit production costs that would need to be more the compensated by the net cost advantage of reusability.
Former French research minister Genevieve Fioraso, who had responsibility for the space sector and more recently was asked by the French government for a space-sector review, told the French parliament on Dec. 7 that reusability's appeal might not be applicable in Europe.
Developing a partially reusable Ariane 6 rocket, she said, would have meant delaying Ariane 6's commercial introduction to 2028. The vehicle is now on track for a 2020 inaugural flight. Longer term, Fioraso said, "it is not clear that such a vehicle would correspond to our economic model."
"A reusable rocket may be less relevant to France than to the United states because our satellites, unlike theirs, mainly go to geostationary orbit, which means our rockets are confronted with the most difficult and abrasive conditions," Fioraso said.
"We have looked seriously at this: The return on investment, for us, would be much less. But still we need to continue research in this area."
Led by CNES, ESA governments in December agreed to early development of a LOX-methane motor called Prometheus, designed to cost 1 million euros ($1.05 million) apiece at commercial production volume. That compares with about 10 million euros for each Vulcain 2.1 LOX-liquid hydrogen engine today.
CNES officials hope ultimately to replace the Vulcain, used as the single main-stage engine on today's Ariane 5 rocket, with multiple Prometheus engines, a implicit nod to the SpaceX policy of a nine-engine first stage.
The CNES-ISRO agreement on future launchers was signed at India's space capital of Bangalore by CNES President Jean-Yves Le Gall and ISRO Chairman A.S. Kiran Kumar, in the presence of French Foreign Minister Jean-Marc Ayrault.
It is unclear exactly how far the joint working group will go before one or the other side decides to pull down the sovereignty curtain.
The work will be preceded by a brief training regime in France — at CNES, Arianespace and Airbus Safran Launchers — for experienced ISRO engineers.
CNES's Astorg: Joint work to have no effect on Europe's Prometheus engine
"The training will be just five days and will deal with quality assurance," said Jean-Marc Astorg, CNES's director of launchers, in an emailed response to SpaceIntelReport questions. "The training relates to the industrialization of the PSLV by ISRO, which wants to give more authority to its industry in the production phase. Up to now this was tightly managed by ISRO.
"CNES will present to ISRO the methods we have used, particularly related to Ariane 5, to go from a development phase under CNES responsibility to an operations phase under industrial management. CNES included industrial-management methods right from the start of the development of Ariane 5, which now has flown 76 times consecutively."
Astorg said no detailed work plan on future launchers has yet be decided between CNES and ISRO, but that both agencies "are looking for faster, less-expensive methods to develop future launchers — for what is sometimes called 'frugal innovation.'"
CNES and ISRO previously worked on rocket technology but the collaboration ceased in the 1990s, when Ariane 5 development was occurring.
Astorg said the new bilateral effort would in no way impact the development of the Prometheus motor by six ESA nations — France, Germany, Italy, Sweden, Belgium and Switzerland — which is scheduled to produce a test prototype before 2020.

Индийские ученые: гелий-3 начнут добывать на Луне к 2030 году
ЦитироватьИндия к 2030 году будет готова добывать гелий-3 на Луне для использования его в качестве энергоресурса, сообщает агентство IANS о ссылкой на заслуженного профессора Индийской организацией космических исследований (ISRO) Сиватхана Пиллаи.
Он отметил, что разработка лунной поверхности, богатой гелием-3, является приоритетным направлением работы ISRO.
"К 2030 году этот процесс (использования гелия-3 как энергоресурса) будет возможен", — цитирует агентство Пиллаи.
Он также добавил, что многие страны изучают возможность добычи гелия-3 на Луне, по словам ученого, ресурсов спутника Земли хватит на всех. Такой же оценки придерживаются российские ученые. Как ранее заявлял доктор физико-математических наук, заведующий отделом исследований Луны и планет Государственного астрономического института МГУ им. Ломоносова Владислав Шевченко, имеющиеся на Луне запасы гелия-3 могут обеспечить землян энергией на пять тысяч лет вперед.
В настоящее время изотоп гелий-3 на Земле добывают в очень небольших количествах, исчисляемых несколькими десятками граммов в год.
На Луне же запасы этого ценного изотопа составляют, по минимальным оценкам, около 500 тысяч тонн. При термоядерном синтезе, когда в реакцию вступает 1 тонна гелия-3 с 0,67 тоннами дейтерия, высвобождается энергия, эквивалентная сгоранию примерно 15 миллионов тонн нефти.

ISRO commissions two major facilities at VSSC

ЦитироватьISRO on Monday commissioned two major facilities – a Hypersonic Wind Tunnel and Shock Tunnel – at the Vikram Sarabhai Space Centre at Thiruvananthapuram as part of its continuous and concerted efforts to minimise cost of access to space. ISRO Chairman Kiran Kumar said commissioning of such facilities would provide adequate data for design and development of current and future space transportation systems in the country.

He said commissioning of the facility symbolises the country's capability in establishing such world class facilities wherein technology from outside is restricted or not available.

The one meter Hypersonic Wind Tunnel and one meter Shock Tunnel have been established with a wide spectrum of simulation capabilities in terms of Mach number, Reynolds number and re-entry velocities, an official release said

Спойлер
These facilities, indigenously designed, developed and 'Made in India' with the support of Indian industries, are the third largest in terms of size and simulation capability in the world, it said.

A few critical technologies, which are under embargo, have been jointly developed by ISRO and industries for realisation of these facilities.

VSSC Director Sivan in his presidential address said though excellent modeling capabilities exists with the advent of powerful computers, there was no other replacement for wind tunnel testing for aerodynamic characterisation.

The new facility would help aerodynamic characterisation of advanced space transportation systems, he said.

The facilities were dedicated in the memory of Satish Dhawan, a pioneer in the field and named as the Satish Dhawan Wind tunnel Complex.

ISRO is planning future missions such as Reusable Launch Vehicles, Two Stage to Orbit, Air Breathing propulsion systems and Human Space Flight Programme, the release added

ЦитироватьСМИ: Индия испытает в начале июня тяжелую ракету-носитель для пилотируемого корабля
НЬЮ-ДЕЛИ, 28 мая. /Корр. ТАСС Евгений Пахомов/. Индийская организация космических исследований (ИСРО) намерена провести в первых числах июня испытательный запуск тяжелой ракеты-носителя индийской разработки. Как сообщил телеканал NDTV, новая ракета позволит реализовать национальную пилотируемую космическую программу.
Носитель GSLV MK-III (его также называют LVM3 - Launch Vehicle Mark-3), способен вывезти полезный груз весом около 8 тонн на околоземную орбиту. Как указывает телеканал, это самая мощная и тяжелая ракета из разработанных в Индии. Ее вес сопоставим с весом 200 индийских слонов (более 640 тонн), и она создана полностью на индийских технологиях.
Если первый этот пуск носителя будет успешным, с его помощью в скором будущем впервые будет отправлен в космос индийский экипаж с индийской территории на индийской ракете, отмечает NDTV. В случае, если этот план осуществится, Индия станет четвертой страной мира после России, США и Китая, которая способна самостоятельно отправлять людей в космическое пространство. С помощью нового носителя на орбиту также будут выводиться на околоземную орбиту спутники различного назначения.
Ранее Индийская организация космических исследований сообщила, что не исключает того, что первым на индийской ракете в космос отправится женщина.
Первым индийским космонавтом стал Ракеш Шарма, который был отправлен на орбиту в составе экипажа советского корабля "Союз Т-11". Нью-Дели долгое время не уделял большого внимания разработке национальной пилотируемой программы, однако после того, как своих космонавтов стал отправлять в околоземное пространство Китай, Индия тоже решила вплотную приступить к разработке собственного орбитального корабля.
По данным местных СМИ, ИСРО уже разработало проект корабля на 2-3 членов экипажа, также идут работы над скафандрами и другим необходимым оборудованием.
