IIT Madras Develops Hybrid Rocket Thruster for VTOL Aircraft
Scientists at IIT Madras have created a new type of rocket engine for planes that can take off and land straight up and down, like a helicopter.
This special engine, called a hybrid rocket thruster, is safer and simpler than regular jet engines.
They tested it using a computer and found it could bring a plane down gently.
This new engine is great for planes that need to land in small spaces without a runway, like on rooftops or in small fields.
The researchers believe this could make air travel very different in the future and is a big step for India in building these kinds of planes.
IIT Madras researchers have developed a novel hybrid rocket thruster.
The thruster is designed for use in Vertical Take-Off and Landing (VTOL) aircraft.
Testing demonstrated a controlled landing speed of 0.66 meters per second.
This technology offers a safer, simpler alternative to traditional engines for VTOL operations.
The development aims to enable VTOL aircraft to operate in diverse locations without runways.
