ISRO has successfully tested the Pushpak Reusable Landing Vehicle (RLV) LEX 02 in Chitradurga, Karnataka.

About Reusable Landing Vehicle (RLV) LEX 02

This test, the second one in the sequence after RLV-LEX-01, showcased the autonomous landing capability of the RLV, known as Pushpak.

Reusable Landing Vehicle (RLV)

1. The RLV is conceptualized as a space plane with a low lift-to-drag ratio, requiring an approach at high glide angles that necessitates landing at high velocities of 350 km/h.

2. This design allows it to transport payloads to low Earth orbits and return to Earth for future use.

3. It uses various indigenous systems, including localized navigation based on pseudolite technology, along with instrumentation and sensor systems developed by ISRO.

Note- The Reusable Launch Vehicle-Technology Demonstrator (RLV-TD) Programme is designed as a sequence of technology demonstration missions aimed at achieving a fully reusable Two Stage To Orbit (TSTO) vehicle.

What was the method used for the experiment?

1. Challenging autonomous landing– The RLV LEX-02 mission showcased the autonomous landing ability of the reusable launch vehicle, named Pushpak, under challenging conditions after being released from a Chinook helicopter at 4.5 km altitude.

2. Automatic control adjustments– It approached the runway autonomously, making adjustments as needed, and landed precisely using its brake parachute, landing gear brakes, and nose wheel steering system.

3. RLV-LEX-01 System reuseAll flight systems from RLV-LEX-01 were reused in this mission after receiving necessary certifications.

4. Agencies involved– The mission was carried out by Vikram Sarabhai Space Centre (VSSC), Liquid Propulsion System Centre (LPSC), and ISRO Inertial Systems Unit (IISU).
