Parachute deployment tests for Gaganyaan
GS Paper - 3 (Space Technology)

ISRO has successfully conducted a series of tests on drogue parachutes, which would play a pivotal role in stabilising the crew module and reducing its velocity to a safe level during re-entry in the planned Gaganyaan human space flight mission.

More about the Mission

The Gaganyaan mission hopes to safely transport astronauts to Space and back. Drogue parachutes are deployed to decrease speed and stabilise rapidly moving objects.
ISRO's Thiruvananthapuram-based Vikram Sarabhai Space Centre (VSSC) successfully conducted a series of Drogue Parachute Deployment Tests at the Rail Track Rocket Sled (RTRS) facility of the Terminal Ballistics Research Laboratory in Chandigarh during 8-10 August.
The tests were conducted in collaboration with Aerial Delivery Research and Development Establishment (ADRDE)/DRDO.
The drogue parachutes, packed within pyro-based devices known as mortars, are cleverly designed to eject the parachutes into the air upon command.
These conical ribbon-type parachutes, boasting a diameter of 5.8 metres, employ a single-stage reefing mechanism, ingeniously minimising canopy area and mitigating opening shock, ensuring a smooth and controlled descent.
During the three comprehensive tests conducted at the RTRS facility, a range of real-world scenarios were simulated to rigorously evaluate the performance and reliability of the drogue parachutes.
The first test simulated the maximum reefed load, marking a groundbreaking introduction of reefing in a mortar-deployed parachute within India.
The second test emulated the maximum dis-reefed load, while the third test showcased the deployment of the drogue parachute under conditions mirroring the maximum angle of attack experienced by the crew module during its mission.
These successful RTRS tests serve as a critical qualification milestone for the drogue parachutes, confirming their readiness for integration into the upcoming Test Vehicle-D1 mission.
Notably, earlier this year, theRTRS tests of Pilot and Apex cover separation parachutes were also conducted, further accentuating the progress of the Gaganyaan mission's parachute system development.
Theintricate parachute sequence for the Gaganyaan crew module's deceleration system encompasses a total of 10 parachutes.

Indigenous ASTRA missile tested
GS Paper - 3 (Defence Technology)

LIGHT COMBAT Aircraft (LCA) Tejas successfully fired the ASTRA indigenous Beyond Visual Range (BVR) air-to-air missile off the coast of Goa. The missile release was successfully carried out from the aircraft at an altitude of about 20,000 ft. All the objectives of the test were met and it was a perfect text book launch.

More about the News

ASTRA is a state-of-the-art BVR air-to-air missile to engage and destroy highly maneuvering supersonic aerial targets.
It is designed and developed by Defence Research and Development Laboratory (DRDL), Research Centre Imarat (RCI) and other laboratories of DRDO.
The test launch was monitored by the Test Director and scientists of Aeronautical Development Agency (ADA), Defence Research and Development Organisation (DRDO), Hindustan Aeronautics Limited (HAL) along with officials from Centre for Military Airworthiness and Certification (CEMILAC) and Directorate General of Aeronautical Quality Assurance (DG-AQA), the aircraft was also monitored by a Chase Tejas twin-seater aircraft.
The LCA programme has been the flag bearer of the Indian Air Force’s (IAF) efforts towards indigenisation of its aircraft fleet.
The nature of this project of national importance, it is required that all stakeholders adopt a collaborative approach towards its success.
It was brought out that all contracted fighter variants of the LCA Mk 1 had been delivered to the IAF.
After the LCA Mk 1, 83 LCA Mk-1A aircraft have also been contracted by the IAF in 2021.
