ISRO has achieved a major milestone in the area of Reusable launch vehicle (RLV) technology, through the RLV LEX-02 landing experiment, the second of the series, conducted at Aeronautical Test Range (ATR), Chitradurga in Karnataka today morning at 7:10 hrs IST.
After the RLV-LEX-01 mission was accomplished last year, RLV-LEX-02 demonstrated the autonomous landing capability of RLV from off-nominal initial conditions at release from Helicopter. The RLV was made to undertake more difficult manoeuvres with dispersions, correct both cross-range and downrange and land on the runway in a fully autonomous mode. The winged vehicle, called Pushpak, was lifted by an Indian Airforce Chinook helicopter and was released from 4.5 km altitude. After release at a distance of 4 km from the runway, Pushpak autonomously approached the runway along with cross-range corrections. It landed precisely on the runway and came to a halt using its brake parachute, landing gear brakes and nose wheel steering system.
This mission successfully simulated the approach and high-speed landing conditions of RLV returning from space. With this second mission, ISRO has re-validated the indigenously developed technologies in the areas of navigation, control systems, landing gear and deceleration systems essential for performing a high-speed autonomous landing of a space-returning vehicle. The winged body and all flight systems used in RLV-LEX-01 were reused in the RLV-LEX-02 mission after due certification/clearances. Hence reuse capability of flight hardware and flight systems is also demonstrated in this mission. Based on the observations from RLV-LEX-01, the airframe structure and landing gear were strengthened to tolerate higher landing loads.

Extremely proud of our ISRO’s achievements. But i strongly believe they should invest in good designers. From logo to space craft to UI, everything needs an overhaul.

I am very happy as DRDO and ISRO both have been making strong in defence system technology to protect my country. My heart leaps up when I behold the achievement of DRDO and ISRO in sky. My heart full 'Pronam' to all the hard working scientists of DRDO and ISRO. Kyon ki mera Bharat mahan.

So this vehicle slows down puerly from drag and lift , I can't see any enginge 😮

@shivamkumar-dw4ue 4 ай бұрын

It will glide from space and will automatically slow down by earth Atmosphere. Then the inertial navigational system will align it with the runaway and will land it. It's pretty bonkers to think that it will align and land without any engine.

But what was the purpose of this test , bcz landing test was successful on first test , so what are the problems were in that , what changes were made , and provide this test data too, and ya why it's too slow , I mean it's too slow development

Last time they dropped the rlv in the alignment of runway. This time the rlv was dropped 4 km away from the runway. So, it needed to align itself with the runway and land.
