Semicryogenic Engine Hot Test
Context
The Indian Space Research Organisation (ISRO) successfully conducted a short-duration hot test of its semicryogenic engine at the ISRO Propulsion Complex (IPRC) in Mahendragiri, Tamil Nadu.
This was the second major milestone in the testing phase of the semicryogenic engine after the first successful hot test held in March.
Key-highlights
- The recent test was a short duration hot test of the Engine Power Head Test Article (EPHTA). It included all critical systems of the engine except the thrust chamber (the part where actual thrust is produced).
- What is EPHTA? It is a test version of the engine that includes all critical engine systems except the thrust chamber, allowing engineers to focus on the performance of specific components.
What is a Semicryogenic engine?
- A semicryogenic engine uses a liquid oxidizer (like liquid oxygen) and a kerosene-based fuel (such as RP-1) that are kept at very low temperatures but not as extremely cold as fully cryogenic fuels like liquid hydrogen.
- In comparison, a full cryogenic engine uses both fuel and oxidizer at extremely low (cryogenic) temperatures.
- Semicryogenic engines are more powerful than traditional engines.
- Once inducted, it will help ISRO's launch vehicles like Gaganyaan, future GSLV Mk III upgrades, and potential heavy-lift vehicles to carry heavier payloads into space.
- Most major space powers like the United States, Russia, and China already use semicryogenic engines.
