The Indian Air Force (IAF) acheived a major milestone one of its AN-32 aircraft landed at the Kushok Bakula Rimpochee Airport at Leh in Ladakh, after a flight powered by a 10% blend of Indian bio-jet fuel.
This is the first time that both engines of the aircraft were powered by the bio-jet indigenous fuel, an official press release said.
The aircraft was flight tested and its performance was validated at Chandigarh Air Base prior to undertaking the operational flight to Leh, it said.
Leh, at an altitude of 10,682 ft above mean sea level, is one of the highest and most difficult operational airfields in the world and is prone to extreme weather conditions. Even during clear weather conditions, landing and taking-off an aircraft at Leh is challenging due to reduced power output of the aircraft engines in the rarefied atmosphere, turbulent wind conditions and proximity of mountainous terrain.
"Evaluating the performance of bio-jet fuel under these conditions is important from operational perspectives. It validates the capability of the aero-engine to operate smoothly with bio-jet fuel at the extremities of the operational envelope. The tests were conducted by a team comprising test pilots from the Aircraft and Systems Testing Establishment, Bengaluru and pilots from the operational squadrons," the release said.
"This successful test flight also demonstrates IAF’s capabilities to absorb newer technology, while sponsoring indigenization. The technology to produce this fuel was developed by CSIR-IIP in 2013, but could not be tested and certified for commercial use due to lack of concurrent aviation test facilities in the country. In 2018, the IAF sponsored this project and channelized its human and material resources for the complete range of fuel testing," it said.
Bio-jet fuel is produced from non-edible Tree Borne Oils, grown and procured from the tribal areas of Chhattisgarh state. IAF’s efforts would assist in reducing carbon footprint and India’s dependence on crude imports, the release added.
