ISRO cryogenic engine for GSLV D5 at HAT(credits: ISRO)

The image is of CUS-5 engine for the GSLV D5 mission. The engine underwent a simulated vacuum ignition test at ISRO's High Altitude Test facility near Mahendragiri. The test demonstrated the successful simulated vacuum ignition and further build up of required operating parameters for high altitude atmospheric flight. Success of the HAT test will further boost India's cryogenic engine development program.
