Daily News Analysis ‘Fighter aircraft escape (ejection) system’ : 3 December

Table of Content

Why in News?

  • DRDO has successfully tested India’s indigenous fighter aircraft escape system using a high-speed rocket-sled trial.

About the test

  • The test was carried out at the Rail Track Rocket Sled facility of the Terminal Ballistics Research Laboratory (TBRL), Chandigarh.
  • The trial was conducted at controlled high velocity to simulate real emergency conditions.
  • It successfully validated three critical functions: canopy severance, ejection seat sequencing, and complete aircrew recovery.
  • The test was conducted in collaboration with Hindustan Aeronautics Limited (HAL) and the Aeronautical Development Agency (ADA).

DO YOU KNOW

Key terms

  • Canopy Severance

  • This means cutting or breaking the aircraft’s glass cover (canopy) quickly so that the pilot can be safely thrown out during an emergency.
  • In simple words: the cockpit cover is removed instantly before the pilot ejects.

  • Ejection Seat Sequencing

  • This means the correct order and timing of events during ejection — such as canopy removal, seat firing, parachute opening, etc.
  • In simple words: everything happens step-by-step in the right sequence so the pilot is not injured.

  • Complete Aircrew Recovery

  • This means the pilot safely lands on the ground and is rescued after ejection.
  •  In simple words: the pilot survives the ejection and can be brought back safely.

About Ejection system
  • The ejection system is a life-saving mechanism that allows a pilot to escape from a damaged or uncontrollable fighter aircraft.
  • It works by jettisoning the canopy, firing the ejection seat using a catapult and rocket motor, and then deploying a parachute for safe descent.
  • Modern systems have “zero–zero capability”, meaning ejection is possible at zero speed and zero altitude.
  • The system includes safety features such as limb restraints, neck protection, automatic parachute deployment, and survival kits.
  • Ejection involves high g-forces and injury risk, so it is used only as a last-resort emergency measure.
