Key Features of ISRO's RLV-TD

The RLV-TD is designed to look like an aircraft, with a fuselage, nose cap, double delta wings, and twin vertical tails.
It features symmetrically placed active control surfaces called Elevons and Rudder.
The RLV-TD is boosted to Mach 5 speeds by a conventional solid booster (HS9) designed for low burn rate.
ISRO has utilized specialized materials like alloys, composites, and insulation to develop the RLV-TD.

ISRO has successfully demonstrated the autonomous landing capability of the RLV-TD through a series of Landing Experiment (LEX) missions.
The latest LEX-03 mission in 2023 simulated high-speed landing conditions of over 320 km/h, showcasing ISRO's expertise in critical reusable launch vehicle technologies.
The LEX-03 mission reused the winged body and flight systems from the previous LEX-02 mission, demonstrating ISRO's capability to reuse flight systems.
The RLV-TD program has validated advanced guidance algorithms for longitudinal and lateral plane error corrections, essential for future orbital re-entry missions.
ISRO's RLV-TD program, though smaller in scale compared to some global peers, represents a significant step for India in developing reusable launch vehicle technology to enable low-cost access to space.
