The Indian Space Research Organization (ISRO) has achieved a significant achievement in the development of its semi-crossing engine. The engine is of high thrust capacity of 2,000 kg of Newton (KN) and will be operated with propellers such as liquid oxygen and kerosene (kerosene). This engine will be used in future ISRO’s major launch vehicle ‘Mark-3’ i.e. LVM3 (LVM3) booster stage.
Successful tests conducted on 28 March
ISRO said that this achievement was achieved when the first hot test of the power head test article (PhTA) of this engine was successfully completed at the ISRO Pranasan complex in Mahendragiri, Tamil Nadu. This test is being seen as the first major success of the Semi-Cryogenic Engine Development Program.
Duration and purpose of testing
The total duration of the test was 2.5 seconds, but this short time was sufficient to test the technical capabilities of this engine. ISRO said that during this time the integrated performance of the engine pre-burner, turbo pumps, start systems and control components was tested. All these systems performed as expected, which strengthened the plan for further tests to ISRO.
Results are promising
ISRO said in the statement that the test was completely according to the forecasts. All the criteria of the engine were found to be normal and satisfactory. Encouraged by the results of this test, ISRO will now do many more tests on the power head test article before the fully integrated construction of the engine to further strengthen its reliability.
New engine will replace the current stage of LVM 3
According to ISRO, this semi-crossenic engine (SE2000) with 2,000 KN capacity will replace the current core liquid stage (L110) of LVM3. It will be called the stage SC120 operated by it, which will improve the ability to lift the payload. This will not only increase the capacity of the current rocket of ISRO, but it will also prove useful for the booster stages of the future large launch throughouts.
Semi-Cryogenic Technology Specialty
The proponent used in this engine is liquid oxygen and kerosene, which is not only relatively safe but is also less dangerous in terms of environment. This propulsion system is completely indigenous and gives better performance than existing systems.
ISRO’s matter of material propulsion system (LPSC) is playing an important role in the development of this entire engine and stage. Successful development of semi-conogenous development can provide new heights to India’s space flight capabilities and will prove to be another major step towards technical self-sufficiency.
