IIT Madras Develops Hybrid Rocket Thrusters for VTOL Aircraft Soft Landing
Imagine airplanes that can land straight down without needing a long runway, like a helicopter.
Scientists at IIT Madras have figured out a new way to make this happen using special rocket engines called hybrid rocket thrusters.
These engines are safer because they use rocket fuel in solid form and a liquid or gas for pushing.
By mixing a real thruster test with a computer simulation, they figured out how to control the speed just right for a gentle landing.
This new technology could help planes land in difficult places like mountains or faraway areas where big airports can't be built.
IIT Madras researchers have successfully demonstrated a new VTOL technology using hybrid rocket thrusters.
The breakthrough combines real-time hybrid rocket thrusters with virtual simulation for controlled soft landings.
Hybrid rocket technology offers enhanced safety, simplicity, and control compared to traditional liquid rocket engines.
This advancement eliminates the need for long runways, enabling aircraft to access remote and rugged terrains.
The findings have been published in the International Journal of Aeronautical and Space Sciences.
