And in the meantime, India is testing an engine for a manned spacecraft

With European politicians hesitant to fund an autonomous manned flight program, India is set to become the fourth space power capable of sending people into space. A fine technological performance for a state that does not have the same financial strength as Europe, which lags behind in some key technical areas.

Initially, the Indian space agency planned to send one or two Astronaut Indians on the occasion of the 75th dayAnd 2022 marks the anniversary of India’s independence. But, r Cowid-19 crisis This forced the country to suspend its inaugural flight until 2024 It will be preceded by two unmanned aerial vehicles scheduled for the first and fourth quarters of 2023, each carrying one. Robot Humanoid equipped with Sensor. The capsule will be added a Orbit 400 km for a 7 day flight before landing in the Arabian Sea from Ahmedabad.

Much less publicized than NASAI ‘ESA Or the space agencies of Russia and China, the Indian space agencies are continuing their activities Manned flight It started several years ago. Gaganyan, the name of the program, has already conducted a number of tests, including suborbital flight, atmospheric re-entry, a rescue tower test of a prototype capsule (excluding an astronaut) 3.7 tons (care in 2014) and a 12.6-ton capsule model four years later. . Also note the flight of the experimental capsule SRE-1 in 2007, which lasted 12 days in orbit.

A version of the launcher for robotic exploration missions is suitable for human spacecraft

A few days ago, risro Successfully carried out a static test Thrust Until the back up Driver Gaganyan is powerful for the program. This Booster The human flight version of the tested S200 thruster that equips Launcher GSLV MkIII. This configuration is named HS200. The test lasts 135 seconds Duration Operation of the first of the three stages of GSLV Mk III.

Instead of building a completely new launcher dedicated exclusively to manned flights, India prefers to build a man-made version of the GSLV Mk III. Launched in 2017, the launcher is capable of launching 10 tons less into orbit and 4 tons into orbit. Transfer orbit Landslide He significantly started the lunar mission Chandrayaan 2 and 3 and Venus (Venus-1) and Mars 2, a probe bound for the second mission bound for Mars should be launched.

India wants to send people into space by 2022

Its essay Remy Decort Published on 08/16/2018

What will be the fourth nation that will send its astronaut into space? Certainly not Europe, which prefers to cooperate in international programs, nor Japan, which is technically lagging behind in this regard. It should be India which has the political will to do it and is slowly acquiring the technologies to do it. Its prime minister has set only one goal. It will be 2022!

After the USSR, the United States and China, will India be the fourth country to send men into space in its own way? Yes, if we rely on the speech delivered by the Prime Minister of India Narendra Modi on the occasion of Independence Day. Apart from the political will, which other grounded countries lack, India also has the financial and technical capacity to achieve this feat.

In view of the latest technological advancement of ISRO (Indian Space Agency) and if we compare it with its program, it has been implemented for the launch of China. The first tycoon In space (Shenzhou 5, October 2003), the 2022 deadline seems optimistic to us. Especially since two unmanned demonstrations and test flights are planned before the manned flight. This first manned mission must see a crew of two or three skies (named after Indian astronauts), possibly with a woman, orbiting the earth for a week.

In the last ten years, India has been acquiring and acquiring critical technologies for human flight (return from orbit, atmospheric re-entry, heat shield, etc.). If this effort continues, there is no doubt that by 2025 it will be able to send a sky into space.

Steps taken successfully

In 2007, ISRO successfully used one Atmospheric re-entry capsule (SRE-1 mission) 485 x 639 km in a circular or elliptical orbit after several days in space. In 2014, he launched a Display of a human capsule Weighing over 3.7 tons, it is 3.1 meters in diameter and 2.7 meters high. For Baptized Care Crew module atmospheric re-entry test, This capsule was large enough for a crew of three. In early July, the crew’s emergency evacuation system was successfully tested during an evacuation test from a capsule if there was a problem with the launch pad.

Finally, India has opened a training center for gagnats in Bangalore with the aim of training and preparing at least four of them so that at least two or even three of them can perform an orbital flight lasting several days.

India wants men in space and a reusable launch vehicle

Remy DeCourt’s article published on 06/01/2012

India, another emerging space power in Asia, wants to do the same with its troubled neighbor China. And better. Its ambitions are high: launching a manned flight before the end of the decade and building a reusable satellite launch system, in short, an unmanned shuttle.

If the aerospace manufacturers and most aerospace companies are directly or indirectly interested in the reusability of launchers, then India is the only country that is betting on everything reusable for access to space. However, it has a kalas family that basically meets its needs. Currently, it is developing a reusable two-stage launcher of the TSTO (Two Stage to Orbit) type that looks great. Spacecraft. No launch date has been announced but the idea is a Protesters This year the flight could be tested. Another project related to recycling, SRE Orbit Return Capsules (Space Capsule Recovery Experiment) Designed to run tests (50) Kg) Inside Weight lossThen bring them back to the ground.

Europe has decided that Next generation launcher (NGL) which will replace the current family AriadneBy 2025, it will not be reusable.

All reusable, a false good idea?

This notion of recycling can quickly fade away. A pen on paper Launcher Reusable has something more tempting as it increases its reliability thanks to the progressive correction of errors in tools while using it.

For many, however, it is still too early to start developingReusable floor Enables significant performance. The technology required for such floors is only partially assimilated. For today’s launchers, recycling their design materials makes it impossible to imagine. And especially those used for thermal protection Construction The floor

Indians in space soon?

Reusing a floor is a real logical headache and, consequently, an economic nonsense. In its recovery, on land or in the high seas, recovery, of Certificate For its integration into flights and launchers, recycling proves to be longer and more expensive than a consumable stage built in about ten units per year. The example of the space shuttle is instructive. Only a partially reusable operational system (ventral tanks and boosters were lost), it had to overhaul a few months between two flights to make dozens of flights a year!

Another major program is to send spacecraft (names given to Indian astronauts) into space. Despite a Stop in its space programDue to its failure in 2010, India reaffirmed that it would be ready to launch two astronauts by itself by the end of this decade. They will fly in a home-made space capsule launched by a GSLV capable of human flight. With this in mind, ISRO has opened an astronaut training center in Bangalore. The goal is to prepare at least four of them so that two of them can fly several days of orbital flight.
