| Brake Parachute for reducing the landing run of MiG-29 has been indigenously developed. Unicross design canopy has 10 m of separation distance from the aircraft tail end. A unique feature of integrated riser and rigging lines has been adopted to reduce its mass. The canopy design has also been optimised with reduced size for mass saving. On pilot’s command the main canopy is deployed providing deceleration to the aircraft. |
