Medical outcomes of emergency escape of Yak-130 aircraft

The article considers the medical outcomes of 5 emergency exits of the Yak-130 aircraft (10 crew members), including 9 (90%) survived. Among the survived pilots, 77.8% had minor injuries, 22.2% had severe. All had multiple 2nd degree burns in the anterior chest, shoulder joints and forearms. Compression fractures of the thoracic vertebral bodies and concussion represent severe injuries. All injuries were received during ejection under off-design conditions (late emergency escape of the aircraft beyond the resolving capabilities of the ejection system and violation of the correct posture for ejection). Severe injuries resulted from a shock overload of the ejection seat energy sensor (under conditions of an incorrect pilot’s position) and a shock overload of landing on a parachute, and light injuries resulted from exposure to fragments of the SOAV pyrocord, which caused burns. In order to increase the injury safety of the emergency evacuation of the Yak-130 aircraft, it is necessary to resolve the use of thermal protective equipment by the crew members.
