Reusable Launch Vehicle Landing Experiment (RLV-LEX) was the second test flight in the RLV Technology Demonstration Programme of the Indian Space Research Organisation (ISRO). The demonstration trials will pave the way for the two-stage-to-orbit (TSTO) fully re-usable launch vehicle. LEX was successfully conducted on 2 April 2023. [2]

Objectives

LEX was the second test flight of the reusable launch vehicle which was developed by India. The test flight objectives included: [1]

Mission profile

On 2 April 2023, ISRO successfully conducted landing experiment (LEX) of RLV-TD. It was the second test which was conducted after Hypersonic Flight Experiment (HEX). The 6.5 meter long smaller prototype of the reusable launcher was taken to a height of 4.5 kilometres by an Indian Air force Chinook helicopter. Upon reaching the necessary height and attaining the correct predetermined parameters, the RLV was released autonomously. The RLV then autonomously maneuvered, glided down and landed on the extended runway in Chitradurga Aeronautical Test Range which was specifically created for the test. For this test, ISRO had collaborated with DRDO and the Indian Air Force. Several new state-of-the-art technologies like Pseudolite system, Ka-band Radar Altimeter, NavIC receiver, indigenous Landing Gear, Aerofoil honey-comb fins and brake parachute system were used and demonstrated in this mission.

After the successful completion of the mission, S. Somanath, chairman of ISRO, said to the media that they are currently planning to conduct more such landing tests so as to check the readiness of software and hardware under different conditions. The next sequence of experiments which are planned to be conducted after Landing Experiment include Re-Orbital Flight Experiment (REX) and Scramjet propulsion experiment (SPEX). [3]

<span class="mw-page-title-main">Spaceplane</span> Spacecraft capable of aerodynamic flight in atmosphere

A spaceplane is a vehicle that can fly and glide like an aircraft in Earth's atmosphere and maneuver like a spacecraft in outer space. To do so, spaceplanes must incorporate features of both aircraft and spacecraft. Orbital spaceplanes tend to be more similar to conventional spacecraft, while sub-orbital spaceplanes tend to be more similar to fixed-wing aircraft. All spaceplanes to date have been rocket-powered but then landed as unpowered gliders.
