New Delhi, Jan. 13 -- Indian Institute of Technology Madras (IIT), Madras researchers have successfully developed and tested ramjet-propelled artillery shells designed to extend the firing range of conventional gun systems by about 50 per cent. This marks a significant milestone in the indigenous development of defence technology.

A ramjet is a type of engine that uses the vehicle's high speed to compress incoming air, mix it with fuel, and generate thrust without moving parts like rotating turbines.

According to a statement from IIT Madras the innovation integrates a ramjet engine into an existing 155 mm artillery shell, replacing the conventional base-bleed unit. Unlike rocket-assisted projectiles or incremental aerodynamic improvemen...
