The Aeronautical Test Range (ATR) in Chitradurga, Karnataka, hosted the third and final test in the Landing Experiment (LEX-03) series at 07:10 1ST.
RLV LEX-03 once again shown the RLV's capacity to land on its own under more difficult release circumstances.
The space agency ISRO said on Sunday that it has successfully completed the Reusable Launch Vehicle Landing Experiment for the third time in a row, proving the launch vehicle's capacity to land on its own under increasingly difficult circumstances.
The Indian Space Research Organization (ISRO) demonstrated its proficiency in obtaining the most essential technologies needed for the development of a Reusable Launch Vehicle (RLV) with this mission, which replicated the approach and landing interface as well as high-speed landing conditions for a vehicle returning from space, according to the space agency.
The Aeronautical Test Range (ATR) in Chitradurga, Karnataka, hosted the third and final test in the Landing Experiment (LEX-03) series at 07:10 1ST.
RLV LEX-03 re-demonstrated the autonomous landing capabilities of the RLV in more difficult release circumstances (cross range of 500 m vs 150 m for LEX-02) and more severe wind conditions, according to an ISRO announcement after the success of the RLV LEX-01 and LEX-02 missions.
The 'Pushpak' was a winged vehicle that was dropped from an Indian Air Force Chinook helicopter at a height of 4.5 km "from a release point 4.5 km away from the runway." Pushpak approached the runway, did cross-range correction maneuvers autonomously, and made a crisp horizontal landing near the centerline of the runway "it claimed.
It also said that the landing velocity of this vehicle approached 320 kmph, in contrast to 260 kmph for a commercial aircraft and 280 kmph for a conventional fighter aircraft, because of its low lift-to-drag ratio aerodynamic arrangement.
According to ISRO, the spacecraft's braking parachute was used to slow down to almost 100 kmph after impact, and then the landing gear brakes were used to halt the vehicle and decelerate it on the runway.
According to Pushpak, it uses its nose wheel and rudder steering system to autonomously maintain a steady and accurate ground roll down the runway during this ground roll phase.
The space agency claims that by simulating a vehicle's approach, landing interface, and high-speed landing circumstances, this mission highlighted ISRO's proficiency in obtaining the most important technologies needed to create a Reusable Launch Vehicle (RLV).
The space agency said that this mission has proven the enhanced guidance system that handles error corrections in the longitudinal and lateral planes, which is crucial for the next Orbital Re-entry Mission.
According to the statement, "Notably, the RLV-LEX-03 mission reused the winged body and flight systems as such without any modifications to them from the LEX-02 mission, demonstrating the robustness of ISRO's capability of allowing designers to reuse flight systems for multiple missions." The RLV-LEX employs multi-sensor fusion, incorporating sensors like inertial sensors, radar altimeters, flush air data systems, pseudolite systems, as well as NavIC. The Space Applications Centre (SAC), ISRO Telemetry, Tracking and Command Network (ISTRAC), and Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota were among the many ISRO centers that collaborated on the project, which was headed by the Vikram Sarabhai Space Centre (VSSC).
The Indian Air Force, the Aeronautical Development Establishment, the Aerial Delivery development and research. It Establishment, the National Aerospace Laboratories, the Indian Institute of Technology, Kanpur, the Indian Aeronautical Industrial Partners, the Indian Oil Corporation of India, and the Airport Authority of India all provided significant support for the mission.
The crew received congratulations from S. Somanath, Chairman of ISRO and Secretary of the Department of Space, for their continued success in handling challenging missions.
The Director of VSSC, Dr. S. Unnikrishnan Nair, emphasized that ISRO's trust in the vital technologies necessary for upcoming orbital re-entry missions is increased by this continuous success.
For this mission to be successful, J Muthupandian is the mission director as well as B Karthik is the vehicle director
