Gaganyaan mission: ISRO to drop crew module from a chopper to test parachute deployment system

Gaganyaan Parachute Test

The Indian Space Research Organisation (ISRO) is preparing for a crucial test as part of the Gaganyaan mission to assess the parachute system of the crew module.

Integrated Air Drop  Test (IADT)

The upcoming Integrated Air Drop Test (IADT) involves a Chinook helicopter dropping the crew module from an altitude of approximately 4-5 km.

Nominal Conditions

The initial IADT aims to simulate a splashdown scenario, where both parachutes deploy as intended, ensuring the system's functionality under regular circumstances.

Off-Nominal Scenarios

Following the first test, subsequent IADT sessions will explore various off-nominal situations, including scenarios where only one parachute deploys, both fail to open, or experience delayed deployment.

Recovery Procedure

After the module's splashdown, a helicopter will locate and mark its position for retrieval by the Navy, which will then transport it to the Chennai coast for further examination.

Importance of Splashdown

The successful recovery of the crew module is critical, especially considering past instances where the module inverted during testing.

Test Vehicle Missions

ISRO plans to conduct test vehicle missions to evaluate system performance further, employing single-stage rockets to simulate space conditions.

Crew Module Configuration

The crew module, designed to accommodate three astronauts, will serve as the pressurized cabin for their journey to and from space, with future flights incorporating a service module housing support systems like propulsion.
