A team of Indian researchers has proposed a new regional aircraft design that could revolutionize air connectivity within the country. In a collaborative effort, Prasenjit Das from IISER Mohali and Prof. Prodyut Das from IIT Kanpur have introduced the D12, a 20-seater aircraft designed specifically for UDAN (Ude Desh Ka Aam Nagrik) operators.
The D12 is notable for its versatility. It can be easily stretched to accommodate up to 40 passengers without requiring additional certification, making it a cost-effective solution for airlines.
The D12 is powered by two Pratt & Whitney PT6A-42a engines, ensuring reliable and efficient performance. Its design incorporates detailed calculations for stability, weight, stress, and other critical factors.
The proposed aircraft has the potential to significantly enhance regional air connectivity in India, providing affordable and accessible air travel to remote areas. By offering a scalable and efficient solution, the D12 could play a crucial role in the growth of India’s aviation sector.
