Researchers at IIT Madras have made a significant breakthrough in aerospace technology with the successful demonstration of a hybrid rocket thruster designed for vertical take-off and landing (VTOL) aircraft. Using a Hardware-in-the-Loop Simulation (HILS) framework that integrates a live hybrid rocket motor with real-time virtual models, the team achieved a controlled soft landing with a touchdown velocity of just 0.66 m/s, critical for safe VTOL operation. The hybrid rocket system combines a solid fuel grain with compressed air oxidizer, offering advantages of throttleability, simplicity, safety, and precise thrust control over traditional liquid engines. This development aims to decentralize air transport by enabling VTOL aircraft and unmanned aerial vehicles (UAVs) to operate from remote or rugged terrain where runways are impractical. Led by Prof. P.A. Ramakrishna, this innovation is poised to transform both civil and military aviation by providing strategic and operational flexibility. The research was published in the International Journal of Aeronautical and Space Sciences and signals progress toward higher technology readiness and potential commercialization.
