Hyderabad: In a development that signals steady progress in India’s private space race, city-based Abyom SpaceTech & Defence, founded by Jainul Abedin has successfully tested its BSE-II liquid rocket engine, taking a meaningful step toward building reusable launch vehicles.
Abyom SpaceTech advances reusable rocket technology
The recent test, though brief, was technically significant. The engine ran for six seconds under controlled conditions, reaching temperatures exceeding 2,200°C while maintaining stable performance throughout. Engineers also observed a consistent and expected exhaust plume, an indicator that the system behaved as designed.
The basic concept of the BSE-II is a small engine of 2.5 kN that was designed completely within BITS Pilani Hyderabad. However, this is not the whole story. The test has proven that the rocket possesses three key features that are essential for reusable rockets. First, the engine produces controllable thrust. Second, it ignites reliably. Third, all systems are integrated flawlessly.
The new engine is an improvement of the previously developed BSE-I engine that incorporated a novel fuel injection method. The combination of both engines has undergone over 250 hot firings in the developmental process, illustrating the iterative nature of the development process.
What stands out is that the entire ecosystem behind the test, from the engine itself to the control systems and test infrastructure, was designed and executed by the company. For a startup operating in a domain traditionally dominated by large institutions, that level of in-house capability is noteworthy.
In terms of future plans, however, it seems that the company has bigger goals. The company intends to build a more efficient cryogenic engine and eventually create a rocket that can perform both vertical launches and landings. Additionally, the company will have to invest more into its testing facilities.
Indeed, building a reusable space rocket is a complicated and time-consuming process. However, with every successful trial, more issues will be addressed. In this regard, it can be said that Abyom’s latest accomplishment, while being far from a groundbreaking discovery, represents a practical step towards it.
