Understanding the Mechanics and Importance of ISRO’s Gaganyaan Crew Escape System (CES)
ISRO's Gaganyaan mission, which aims to send Indian astronauts to low-earth orbit, incorporates a vital Crew Escape System (CES). The CES is designed to rapidly separate the crew module from the LVM3 launch vehicle in case of a malfunction during the atmospheric phase of flight. There are two types of CES: puller type (used in Gaganyaan) and pusher type (used by SpaceX). ISRO has successfully tested the CES using a cost-effective Test Vehicle (TV-D1) powered by a Vikas engine. The system ensures astronaut safety by moving the module to a safe distance before a parachute-assisted splashdown in the sea.
Key Points
- The Crew Escape System (CES) is critical during the atmospheric phase where the rocket faces high structural loads.
- Gaganyaan uses a 'puller type' CES that pulls the crew module away from the launch vehicle.
- The Test Vehicle (TV-D1) validated the system under transonic conditions in October 2023.
- The Integrated Vehicle Health Management system monitors parameters to decide when to activate the CES.
