What is GSLV
GSLV A satellite launcher Rocket is. Its main work is in Earth’s orbit. satellites have to deliver. Satellites heavier than 2 tons with an altitude of 36,000 km Geostationary Orbit/Geosynchronous Orbit for installation in GSLV The vehicle (Geosynchronous Satellite Launch Vehicle- GSLV) are used.
These require cryogenic engines. Cryogenics or cryophysics is the branch of science that deals with the study of the state and behavior of matter at very low temperatures. Cryogenic engines have been built on this technology in which liquid hydrogen (-253 °C) is used as fuel and liquid oxygen (-183 °C) as oxidiser.
When heated, these gases expand rapidly and give a tremendous boost to the vehicle. GSLV The technology of the vehicles is currently with only a few countries. In which India, USA, Russia, France, China and Japan are included. India’s GSLV (Mark-1) with a load carrying capacity of 1.8 tonnes, including Russian cryogenic engine are attached.
The length of the entire vehicle is 49.1 meters and weight is 401 tons. It is a three stage rocket. The first stage burns up to give 25% velocity to the vehicle, the second stage also gives 25% velocity and the third stage (in which the cryogenic engine is attached) burns up to provide 50% velocity and gives the satellite 36000 km. Places it in a geostationary orbit at an altitude of .
first step The main motor of the vehicle is powered by solid propellant (Hydroxy Terminated Poly Butadiene-HTPB). It carries 129 tonnes of propellant. Four boosters are attached to the first stage which are powered by liquid propellant (UDMH-Unsymmetrical Dimethyl Hydrazine + Nitrogen tetroxide). Each booster motor can carry 40 tons of propellant.
second stage It uses 37.50 tonnes of propellant and the top stage uses a Russian cryogenic engine that carries 12.50 tonnes of liquid hydrogen and oxygen.
third step Burning provides maximum thrust to the vehicle and puts the communication satellite aboard it into the Geostationary Transfer Orbit (GTO).
GSLV first flight
GSLV-D1 Cryogenic engine (Russian) was used for the first time in an Indian rocket. The first flight of GSLV-D1 (GSLV-D1) was conducted on 28 March 2001.
A second before the launch, there was a sudden obstruction. As soon as the computer ordered the ignition of the four liquid-propellant-powered Strap on Motors attached to its first stage, one of its motors caught fire (due to a failure in its gas generator that could not generate enough pressure and the above The motor’s ‘Vikas’ engine failed to generate enough 95% buoyancy), the automatic protection system quickly detected a lack of proper pressure and automatically aborted the launch by stopping the ignition of the four booster motors, thus causing heavy damage. Went.
GSLV’s second flight
GSLV Its second flight (Mission GSLV-D2) was conducted on 8 May 2003 from Satish Dhawan Space Centre, Sriharikota in which it successfully launched India’s telecommunication satellite ‘GSAT-II’ at a distance of 36,000 km. placed in a geostationary orbit at an altitude of .
‘GSAT-II’ (Geostationary Satellite) is the second satellite of this series. GSLV This flight was significantly improved from its previous flight. The weight of ‘G SAT-I’ is 1540 kg. While the weight of ‘G SAT-II’ was 1800 kg. Is. Thus ISRO achieved an increase of 30% in its launch capability.
GSLV’s third flight
GSLV GSLV on 20th September, 2001. third flight of (मिशन First Opreational Flight GSLV-FO) India’s first educational rocket Satellite – Edusat (Educational Satellite EDUSAT) It was placed in geostationary orbit 17 minutes after take-off.
The weight of the satellite is 1950 kg. Is. It was a ‘big satellite’ installed by ISRO. Which is completely dedicated to educational services. The working period of the satellite is estimated to be 7 years. This GSLV Its first operational flight was on 18 April 2001.
and flights of May 8, 2003 Developmental Flights) in which GSAT-| and communication satellites named GSAT-II were launched.
GSLV’s fourth flight
GSLV The fourth flight of the rocket (Mission GSLV-FO2) was unfortunate. On July 10, 2006 at 5:38 pm, the rocket took off from the Satish Dhawan Space Center (SDSC), Sriharikota but 60 seconds after take-off, the satellite ‘INSAT-4C’ was also destroyed along with the rocket.
2180 kg. The cost of the satellite was Rs 96 crore and the cost of the rocket was Rs 150 crore. The reason for the failure of this vehicle was that one of its first stage boosters suddenly failed to build up pressure within 0.2 seconds of flight. Control of the launch vehicle was impossible with just three boosters and hence the vehicle deviated from its intended target and ended up in shoals of fire and sank into the Bay of Bengal.
GSLV’s fifth flight
GSLV The fourth launch of ‘ISRO’ was definitely a setback, but soon the scientists of ‘ISRO’ introduced their technical proficiency and resolved it. GSLV held on 2nd September, 2007. fifth flight of (Mission GSLV-F04) was completely flawless. Its flight from Sriharikota was scheduled to be held at 4:21 pm but due to some technical errors it could be delayed by 1 hour 50 minutes.
The rocket took off at 6:21 am and almost 17 minutes later successfully placed the state-of-the-art telecommunication satellite ‘INSAT-4CR’ in the Geostationary Transfer Orbit (GTO). 2130 kg. Weighing this satellite, the high-capacity 12 KU. The band’s transponders are attached.
The working life of the satellite is estimated at 10 years. It is to be hoped that this h. Services will be augmented and information can be collected directly from satellite. The satellite is providing its services to the nation efficiently. After the 5th flight of GSLV, many more flights were successful.
