Khaled Bakhtiar, a resident of Hyderabad, developed a miniaturised gas turbine jet engine  which involves intensive engineering, is challenging because it must withstand high rotational speeds, temperatures, and wind speeds. Its construction also necessitates the use of metal alloys that are stronger than steel.

Bakhtiar received an award from defence minister Rajnath Singh at the DefExpo 2022 in Gujarat’s Gandhinagar in October after participating in the Dare 2 Dream – DRDO Innovation Contest at the Mahatma Mandir Convention and Exhibition Centre. He also received a ‘3 lakh cash prize.

Miniature gas turbine jet engines are powered by a variety of fuels, including aircraft fuel, diesel, kerosene, and compressed natural gas (CNG). The vast majority of the components are made in India. These engines have produce approximately 8kg of thrust and operate at approximately 1,20,000 RPM.

“The sand-casting method is used to make the majority of miniature jet engines.” I created the model with a high-precision five-axis CNC machine. The best part is that it can be modified and expanded at any time. It eliminates the need for costly mould making by making changes to the CAD model, and later the CNC machine. No one else in the country, as far as I know, has built such an engine,” Khaled said.
