https://www.livemint.com/news/india/isro-gets-crew-module-from-hal-for-first-development-launch-of-gaganyaan-11660799875580.html [18 Aug 2022]
VSSC, ISRO received CMF (Crew Module Fairing) and HEM (High-altitude Escape Motor) Thrust-transfer Structure (HTS) from HAL today:
New Delhi: The Indian Space Research Organisation (ISRO) has showcased two space equipment built by Hindustan Aeronautics Limited (HAL), to be used in the first unmanned development launch of India’s manned space mission, Gaganyaan. Announced by the Indian central space agency earlier today, this is the second crew module fairing (CMF) that ISRO has taken delivery of for Gaganyaan.
Unnikrishnan Nair, director of ISRO’s Vikram Sarabhai Space Center (VSSC), took delivery of the CMF structure, as well as a high-altitude escape motor Thrust-transfer Structure (HTS). The latter will be tasked with firing an escape motor to keep humans aboard the mission safe, and work towards transferring the requisite engine power to a crew escape module — in case of failure of any equipment aboard ISRO’s mission.
In June this year, ISRO’s VSSC also took delivery of the first CMF structure, built by Bengaluru-based Alpha Design Technology Limited. While both the CMF modules are likely to be used in some form, ISRO confirmed that the CMF it received from HAL earlier today would be used in the first trial or development mission of Gaganyaan.

Integrated Main Parachute Airdrop Test (IMAT)
On Friday, Vikram Sarabhai Space Centre, where many Gaganyaan activities are progressing, conducted a major development test “Integrated Main Parachute Airdrop Test, or IMAT “ of its crew module deceleration system at the Babina Field Fire Range (BFFR) in the Jhansi district of Uttar Pradesh. This test marks a significant milestone toward realizing the nation's ambitious Gaganyaan project.
Parachute based Deceleration system for Crew module
For Gaganyaan Crew module, the Parachute system consists of a totally of 10 no. of parachutes. In flight, the parachute sequence starts with deployment of 2 Nos. of Apex cover separation parachutes (protection cover for the Crew Module Parachute compartment) followed by 2 Nos. of Drogue parachute deployment to stabilise & bring down the velocity. Upon Drogue parachute release, 3 Nos. of Pilot chute will be used to extract 3 Nos. of Main parachute individually, to reduce the speed of the Crew module to safe levels during its landing. Two of the three main chutes are sufficient to land the astronauts on earth, and the third is redundant. Each parachute's performance must be evaluated by complex testing methods using Rail Track Rocket Sled (RTRS) tests for smaller Parachutes and Aircraft/ Helicopters for the Main parachutes.
The Integrated Main Parachute Airdrop Test simulated the case when one Main parachute failed to open and it is the first in a series of tests planned to simulate different failure conditions of the parachute system before it is deemed qualified to be used in the first human spaceflight mission. In this test, a 5-ton dummy mass, equivalent to the Crew module mass, was taken to an altitude of 2.5 kilometres and dropped using the Indian Air force’s IL-76 aircraft. Two small pyro-based mortar-deployed pilot parachutes, then pulled the Main parachutes. The fully inflated Main parachutes reduced the payload speed to a safe landing speed as the entire sequence lasted about 2-3 minutes and the payload mass landed softly on the ground.
The design and development of the Parachute based Deceleration system for Crew module is a joint venture between Indian Space Research Organisation (ISRO) and the Defence Research and Development Organization (DRDO) and with this test, a significant milestone toward realizing the nation's ambitious Gaganyaan project is achieved with the active coordination between the country’s premier agencies, namely ISRO, DRDO, the Indian air force, and the Indian Army.

https://twitter.com/isro/status/1623295318547927040The trials as part of the preparation for Crew Module recovery operations for the Gaganyaan mission have commenced.
On Feb 7, 2023, initial trials in a closed pool were conducted in the Water Survival Test Facility (WSTF) of @indiannavy at Kochi.
https://www.isro.gov.in/Recovery_trials_Gaganyaan_Mission.htmlCommencement of Recovery trials for the Gaganyaan Mission
Feb 08, 2023
On February 7, 2023, ISRO, along with 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, center 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 paramount importance and it has to be carried out with the minimum lapse of time. Hence 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 finalized. The recovery trials will be initially carried out in a closed pool followed by trials in a harbor and in the open sea.
The operations carried out on February 7, 2023, 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. WSTF is a state-of-the-art 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 utilization of recovery accessories. The feedback from the recovery team/trainers helps improve the recovery operations SoP, design various recovery accessories, and finalize the training plan.
