Gulfstream G700 aircraft completes successful test on sustainable fuel

Aviation has taken a major step toward reducing its environmental impact. This was reported by Zamin.uz.

Gulfstream Aerospace has successfully completed extensive flight tests of its Gulfstream G700 — considered its most advanced business jet — using 100% sustainable aviation fuel. The research demonstrated the feasibility of completely replacing conventional aviation kerosene in practice.

The achievement has been highly praised by industry specialists. The Gulfstream G700, equipped with Rolls-Royce Pearl 700 engines, flew at an altitude of over fifteen kilometers above sea level.

This altitude is standard for modern business aviation, but for the first time, a flight at such a distance was conducted without using a single drop of fossil fuel. During the tests, the specially equipped aircraft functioned as a flying laboratory, recording all technical parameters.

The project involved leading scientific organizations worldwide, including NASA, the U.S. Federal Aviation Administration, the German Aerospace Center, and specialists from Rolls-Royce. Researchers compared the environmental impact of three types of fuel in the atmosphere.

These included conventional kerosene, a blend of sustainable fuel, and 100% pure sustainable fuel. During the experiment, the laboratory aircraft flew behind another aircraft, analyzing the composition of its exhaust gases and the soot particles formed in the atmosphere.

For this, the cabin was filled with special measuring instruments, and the crew underwent specific training to maintain a minimal distance between the aircraft. This process allowed for precise measurement of atmospheric pollution levels.

The main advantage of sustainable aviation fuel is that it contains virtually no aromatics or harmful impurities found in regular kerosene. This significantly reduces the amount of solid particles emitted from the engines.

According to Gulfstream’s preliminary findings, using this new type of fuel has significantly reduced the environmental impact of aviation. All collected data will now be submitted to international aviation regulatory bodies and climate scientists.

This information will serve as a key foundation for developing new ecological standards for aviation and establishing requirements for sustainable fuels. For regions like Uzbekistan, where air transit is actively developing, such technologies will undoubtedly gain importance in the future.
