Today, VSSC/ISRO successfully tested a hybrid motor at ISRO Propulsion Complex, Mahendragiri.
A 30 kN hybrid motor with HTPB fuel & liquid oxygen oxidizer demonstrated ignition & sustained combustion for the intended 15 s
Hybrid motors facilitate throttling and enable the re-start capability. While both HTPB and LOX are green, LOX is safer to handle.
The hybrid motor tested today is scalable & stackable, potentially paving the way for a new propulsion system for future launch vehicles
