The Vikram Sarabhai Space Centre (VSSC) successfully carried out a series of drogue parachute deployment tests in collaboration with the Aerial Delivery Research and Development Establishment (ADRDE), the Indian Space Research Organisation (ISRO) said on Friday (11 August).
These tests took place at the Rail Track Rocket Sled (RTRS) facility of the Terminal Ballistics Research Laboratory in Chandigarh between Tuesday and Thursday (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, the ISRO (Indian Space Research Organisation) explained.
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.
