A high school student from western Turkey's Eskişehir has designed a gas-turbine turbojet engine that can run on six different fuels.

Eray Sarısöğüt, 17, told Anadolu Agency (AA) that his engine can run on kerosene, liquefied petroleum gas (LPG), propane, 130-octane aviation gasoline, diesel oil and butane."The ability to use diferent fuels can bring down the costs. It is a high performance engine and has a combustion chamber made by Tusaş Engine Industries [TEI]," he said.

Sarısöğüt, who is in 11th grade at Sabiha Gökçen Vocational Education High School, said the gas-turbine turbojet is also environmentally friendly.

Arif Özkan, project adviser and a teacher at the school's aviation maintenance department, said this was a "first" in terms of the types of fuel the turbojet engine can use.

"The combustion chamber we received from TEI is a key part of the project. Usually, a turbojet engine that runs on kerosene will cost you at least $100,000," Özkan said.

"But by doing it indigenously, we have managed to bring down the costs to TL 5,000 ($1,125). Many schools have requested us to make more for educational purposes," he added.
