BENGALURU: Isro late on Monday (Mar 6) said it conducted the “Rail Track Rocket Sled” deployment tests of the Gaganyaan pilot (small auxiliary chutes) and apex cover separation (ACS) parachutes in cluster configurations at the Terminal Ballistics Research Laboratory (TBRL) between March 1 and 3.
“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 the Gaganyaan mission to extract and deploy the main parachutes independently,” Isro said.

The second test, it added, simulated the clustered deployment of two ACS parachutes under maximum dynamic pressure conditions.

“The test also simulated clustered deployment at a 90° 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,” Isro said.
