GSLV Mk III is three stage heavy lift launch vehicle with a higher payload designed and developed by an Indian space agency namely the Indian space Research Organization (ISRO) which is the main moto to launch any satellites to the geostationary orbit within its capacity.
The first successful orbital test was conducted on 5th June 2017 at Satish Dhawan Space Centre, Andhra Pradesh by ISRO with a spending cost of ₹367Crore.
Post well tested of the launcher again Indian govt sanctioned $580 million to build 10 GSLV Mk III rockets within a course of 5years.
Till now this rocket has been used for several successful missions like Care, Space capsule,2nd Lunar mission and Chandrayaan-2, For the upcoming Gaganyaan crewed mission also it was recommended to use which is under IHSP(Indian Human Spaceflight Programme).
GSLV Mk III Full Form
The full form of GSLV Mk III is Geosynchronous Satellite Launch Vehicle Mark III, Which is the biggest launch vehicle as of now by India to provide maximum thrust to carry the satellite to orbit.
GSLV Mk III Design
It devided into two parts one is first stage and another one into the second stage.
1st Stage: it consists of two S200 solid fuel booster which helps to provide thrust to the vehicle. To control the vehicle electro hydraulic actuators are there. For each 130sec the booster generates 3,578.2KiloNewton thrust to the rocket.
2nd Stage: this is the liquid fuel part where it contains 110metric tons of UDMH and N2O4(Nitrogen Tetroxide). Basically this will be taken care of the two Vikas 2 engines which generate 766 kilonewton thrust per engine. Vikas engine is also known to provide cooling with managing weight during the appropriate stage.
CE-20: This is used on the design to make sure it will produce 200Kilonewton of thrust to pump the launcher. This is also the first gas generator cryogenic engine made by the country.
- GSLV MK III is a heavy lift launch vehicle.
- It is capable to carry satellites into Geosynchronous Orbit upto a weight of 4ton and 10ton to a low earth orbit.
- Two liquid boosters S200 were attached either side of the rocket for lift off.
- Launcher GSLV Mk III-D1 with payload GSAT-19 launched on 5th June 2017, SDSC, Sriharikota.
- Launcher GSLV Mk III-D2 with payload GSAT-29 also launched on 14th November 2018, SDSC, Sriharikota.
- Second lunar mission also succeeded through this GSLV.
Specification of GSLV
there are a number of important specifications are there which are listed one by one below:
Payload to GTO
The full form of GTO is Geosynchronous Transfer Orbits. It was designed to carry 4000kg of class satellites into Geosynchronous Transfer Orbits of GSAT series like GSAT-19.
Payload to LEO
The fullform of LEO is Low Earth Orbit and it was designed to carry 8000kg of class satellites into Low Earth Orbit of GSAT series like GSAT-29.
Liquid Propulsion Systems Centre has developed and architected namely CE-20, the biggest cryogenic engine of India. The height of the engine is 13.5 m whereas the diameter is 4m with a fuel capacity of 28ton.
Solid Rocket Boosters
There are a total of two solid rocket boosters are attached to either side of the rocket launcher to yield the heavy thrust required by the vehicle to lift off from the base. This will require a fuel of 205ton with a height of 25m and a diameter of 3.2m.
The Liquid Propulsion Systems Centre also designed and manufactured the L110 which was empowered by 2 vikash engine. The height and diameter of the stage is around 21m and 4m with a fues capacity of 110ton.
Uses of GSLV Mk III
GSLV Mk III is a launcher rocket which was used in lifting of several satellites to the earth orbit whether it may be Geosynchronous or Low earth orbit for the communication. All the launches are listed below:
