India’s Dry-Kaveri engine, a non-after burner engine at the Russian High Altitude Test Facility went through its paces at simulated altitudes of 43000 ft where it also managed to generate 48.5kN of thrust much more than the benchmark target set at the 46kn that it had to demonstrate.

Dry-Kaveri clearing one of the main flight envelope is crucial for the HALE-Class Stealth aircraft that it will power under the Futuristic Unmanned Fighter Aircraft (FUFA) program that will feature Internal Weapons Bay (IWB) to be used for Deep-Air Strikes in contested Airspace.

FUFA will have a Service ceiling of 50,000 ft that also can be used to gather near real-time, high-resolution images in all types of weather and during day and night. Commercial passenger aircraft typically fly at altitudes of between 31,000 and 38,000 feet or 9 to 11 km.
