Gaganyaan Drogue Parachute
Why in News?
The Gaganyaan Drogue Parachute is in the news because DRDO successfully conducted a critical qualification-level load test.
Key Features
- Primary Function: Acts as the "first brake" for the Gaganyaan Crew Module during its re-entry into Earth's atmosphere. It stabilizes the 5.3-ton module and reduces its velocity from supersonic speeds to a safe level.
- Design & Specifications:
- Type: Conical ribbon-type parachute.
- Size: Boasts a diameter of 5.8 metres.
- Deployment: Packed within pyro-based devices called mortars, which eject them upon command.
- Reefing Mechanism: Employs a single-stage reefing mechanism to minimize opening shock and ensure controlled descent.
- Recovery Sequence: The drogue parachutes are the second in a sequence of 10 parachutes:
- Two Apex Cover Separation parachutes (remove protective cover).
- Two Drogue parachutes (stabilize and decelerate).
- Three Pilot parachutes (extract the main parachutes).
- Three Main parachutes (final deceleration for safe splashdown).
- Collaborative Development: The parachute system is a joint effort between ISRO (Vikram Sarabhai Space Centre) and DRDO (Aerial Delivery Research and Development Establishment and Terminal Ballistics Research Laboratory).
- Strategic Significance: Clearing these tests is non-negotiable for astronaut survival. It marks India's progress toward joining the elite group of nations (USA, Russia, China) with independent human spaceflight capability.
