ISRO Tests Cryogenic Engine for Next LVM3 Mission
ISRO has successfully completed a crucial test for its next LVM3 mission, ensuring the reliability of its powerful cryogenic engine.
Source: GNews ISRO SpaceThe Indian Space Research Organisation (ISRO) recently conducted a flight acceptance hot test of the CE20 cryogenic engine. This engine will power the cryogenic upper stage of the LVM3 rocket, which is ISRO's heaviest launch vehicle. The test took place at the ISRO Propulsion Complex (IPRC) in Mahendragiri, Tamil Nadu. The CE20 engine performed as expected for 25 seconds during the test. All engine parameters were found to be satisfactory. This successful test is a significant step towards the upcoming LVM3-M4 mission, which is scheduled to launch Chandrayaan-3, India's third lunar mission. The LVM3 rocket is a three-stage vehicle, and the cryogenic stage is vital for carrying heavy payloads into geostationary transfer orbit (GTO). ISRO continues to enhance its launch capabilities through such rigorous testing.
This news is important for competitive exams under Science & Technology, specifically Space Technology. Aspirants should understand ISRO's launch vehicles, their stages, and key missions like Chandrayaan-3. Questions often appear in UPSC GS Paper III and SSC General Awareness regarding India's space achievements, rocket components, and mission objectives. Knowing the role of cryogenic engines and the LVM3 rocket is crucial for these exams.
- ISRO conducted the flight acceptance hot test of the CE20 cryogenic engine.
- The test was performed at the ISRO Propulsion Complex (IPRC) in Mahendragiri, Tamil Nadu.
- The CE20 engine is designed for the cryogenic upper stage of the LVM3 launch vehicle.
- The test duration was 25 seconds, with all parameters found satisfactory.
- The LVM3-M4 mission, carrying Chandrayaan-3, will use this engine.
- LVM3 is ISRO's heaviest operational launch vehicle.
A rocket engine that uses propellants (fuel and oxidizer) stored at very low temperatures, typically liquid hydrogen and liquid oxygen. These engines offer high efficiency and thrust, making them suitable for launching heavy satellites into higher orbits. India developed its own cryogenic engine technology, which was a significant achievement.
ISRO's heaviest operational launch vehicle, formerly known as GSLV Mk-III. It is a three-stage rocket designed to launch 4-ton class satellites into Geosynchronous Transfer Orbit (GTO) or 8-ton class satellites into Low Earth Orbit (LEO). It has successfully launched missions like Chandrayaan-2 and OneWeb satellites.
Located in Mahendragiri, Tamil Nadu, IPRC is a unit of ISRO responsible for research and development of liquid propulsion systems for launch vehicles and satellites. It plays a crucial role in testing and qualifying engines and stages for various ISRO missions, including cryogenic engines.
Examiners frequently ask about ISRO's major missions, launch vehicles (like LVM3, PSLV), and key technologies such as cryogenic engines. Focus on the names of missions, their objectives, and the specific rockets used.
Remember 'CE20 for LVM3' Cryogenic Engine 20 powers Launch Vehicle Mark-3, taking India to the Moon with Chandrayaan-3.
Frequently Asked Questions
What is the significance of a cryogenic engine in space missions?
A cryogenic engine is significant because it uses highly efficient propellants like liquid hydrogen and liquid oxygen, stored at extremely low temperatures. This allows rockets to carry heavier payloads and achieve higher orbits, which is crucial for launching communication satellites and deep-space missions.
Which ISRO mission will use the CE20 cryogenic engine after this test?
The CE20 cryogenic engine, after its successful flight acceptance test, will be used in the LVM3-M4 mission. This mission is planned to launch Chandrayaan-3, India's third lunar exploration mission, aiming for a soft landing on the Moon's surface.
Where is the ISRO Propulsion Complex (IPRC) located?
The ISRO Propulsion Complex (IPRC) is located in Mahendragiri, in the Tirunelveli district of Tamil Nadu. It is a vital center for ISRO's research, development, and testing of liquid and cryogenic propulsion systems for its various space programs.
