Chandigarh.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The rocket-sled system replicates high-speed, in-flight aerodynamic conditions on the ground.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Using a dual-sled setup, the forebody of the indigenous LCA was mounted and accelerated along rail tracks.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Through the phased firing of multiple solid rocket motors, the system achieved a precisely controlled speed of 800 km\/h, enabling accurate evaluation of the aircraft\u2019s escape system under realistic conditions.<\/span><\/li>\n<\/ul>\n<h2><b>Why Dynamic Ejection Tests Are More Challenging<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Dynamic ejection tests simulate real flight conditions, unlike static tests conducted at zero altitude and zero speed.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">They are the <\/span><b>true
