Chennai: The Indian Space Research Organisation (ISRO) conducted the Rail Track Rocket Sled deployment tests of the Gaganyaan Pilot and Apex Cover Separation (ACS) parachutes in cluster configurations.
The tests were conducted at the Terminal Ballistics Research Laboratory (TBRL), Chandigarh, on March 1 and 3, ISRO said Tuesday.
The first test simulated the clustered deployment of two pilot parachutes. One parachute was subjected to a minimum angle with respect to flow conditions and the second parachute was subjected to a maximum angle with respect to flow.
These pilot parachutes are used in India’s first manned Gaganyaan mission to extract and deploy the main parachutes independently.
The second test simulated the clustered deployment of two ACS parachutes under maximum dynamic pressure conditions, ISRO said.
The test also simulated clustered deployment at a 90-degree angle of attack conditions for the crew module.
The ACS parachutes are used in the Gaganyaan mission for the separation of the apex cover mounted on the Crew Module. Both pilot and ACS parachutes were deployed using a pyrotechnic mortar device.
The Gaganyaan parachute system development has been a joint effort by Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram and
Aerial Delivery Research and Development Establishment (ADRDE), Agra.
