Gaganyaan Mission: ISRO conducts Drogue Parachute Deployment Test

Chennai: As part of India’s proposed human space mission, the Indian Space Research Organisation (ISRO) said that it had successfully conducted a series of Drogue Parachute Deployment Tests.

According to the Indian space agency, the test was conducted at the Rail Track Rocket Sled (RTRS) facility of the Terminal Ballistics Research Laboratory, Chandigarh, from Tuesday to Thursday.

The tests were conducted in collaboration with Aerial Delivery Research and Development Establishment (ADRDE)/DRDO.

The Gaganyaan mission entails the safe transportation of astronauts to space and back.

A crucial component of this mission is the deployment of drogue parachutes, which play a pivotal role in stabi-lizing the crew module and reducing its velocity to a safe level during re-entry, ISRO said.

Drogue parachutes, packed within pyro-based devices known as mortars, are ingeniously designed to eject the parachutes into the air upon command. These conical ribbon-type parachutes, boasting a diameter of 5.8 meters, employ a single-stage reefing mechanism, ingeniously minimising canopy area and mitigating opening shock, ensur-ing a smooth and controlled descent.

During the three comprehensive tests conducted at the RTRS facility, a range of real-world scenarios were simu-lated to rigorously evaluate the performance and reliability of the drogue parachutes, ISRO said.

The first test simulated the maximum reefed load, marking a groundbreaking introduction of reefing in a mor-tar-deployed parachute within India.

The second test emulated the maximum disreefed load, while the third 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, ISRO added.

Earlier this year, the RTRS tests of Pilot and Apex cover separation parachutes were also conducted, further ac-centuating the progress of the Gaganyaan mission’s parachute system development. (IANS)
