ISRO tests hybrid motors successfully, plans to develop new rocket propulsion technology

ISRO tests hybrid motors successfully: The Indian Space Research Organization (ISRO) successfully tested a hybrid motor. This may lead to the development of a new propulsion system for next launch vehicles. The Bengaluru-based space agency claimed that the 30 kN hybrid motor tested at the ISRO Propulsion Complex (IPRC) at Mahendragiri in Tamil Nadu is stackable and scalable.

ISRO tests hybrid motors successfully: Key Points

• The ISRO Liquid Propulsion Systems Center (LPSC) provided support for the test.
• Liquid oxygen (LOX) served as the oxidizer and hydroxyl-terminated polybutadiene (HTPB) served as the fuel for the motor.
• A hybrid motor employs solid fuel and liquid oxidizer, as opposed to solid-solid or liquid-liquid combinations.
• It was explained that using liquids makes throttling easier and that managing the flow rate of LOX makes it possible to restart.
• Both HTPB and LOX are environmentally friendly, but LOX is safer to handle, according to ISRO.
• According to the statement from ISRO, “The test of a hybrid motor with a 30 kN flight equivalent showed ignition and sustained combustion for the planned 15 seconds. The motor function was adequate.”
