ISRO, along with the Indian Navy carried out initial recovery trials of Crew Module in the Water Survival Test Facility (WSTF) of the Indian Navy, at Kochi. The trials were part of the preparation for crew module recovery operations for the Gaganyaan mission that will be carried out in Indian waters with the participation of Indian Government agencies, the overall recovery operations being led by Indian Navy.
A Crew Module Recovery Model (CMRM) that simulates the mass, centre of gravity, outer dimensions, and externals of the actual Crew Module at touchdown was used for the trials. The sequence of operations required for the recovery of the Crew Module were carried out as part of the trials.
As the safe recovery of the crew is the final step to be accomplished for any successful human spaceflight, it is of importance and it has to be carried out with the minimum lapse of time. The recovery procedures for various scenarios need to be extensively practiced by carrying out a large number of trials. The Standard Operating Procedures (SoP) for recovery of Crew and Crew Module need to be finalised. The recovery trials will be initially carried out in a closed pool followed by trials in a harbour and in the open sea, says a release from ISRO.
The operations carried out on Tuesday form the initial recovery trials of Crew Module in a closed pool. Different phases of recovery trials starting with the recovery of the Crew Module to the flight crew training are planned at WSTF. This facility of the Indian Navy that provides realistic training of aircrew for escape from a ditched aircraft under varied simulated conditions and crash scenarios. WSTF simulates different sea state conditions, environmental conditions, and day/night conditions.
These trials assist in validating the SoP, and training recovery teams as well as the flight crew. They provide valuable inputs for the utilisation of recovery accessories. The feedback from the recovery team/trainers helps improve the recovery operations SoP, design various recovery accessories, and finalise the training plan, the release said.
