due to injury, the dif culty of egress from a con ned space, g forces, the air ow past the aircraft, and other factors. The rst ejection seats were developed independently during World War II by Heinkel and SAAB. Early models were powered by compressed air and the rst aircraft to be tted with such a system was the Heinkel He 280 prototype

Andriana Kuzmeniuk Ejection seat 25.08.1929 In aircraft, an ejection seat or ejector seat is a system designed to rescue the pilot or other crew of an aircraft (usually military) in an emergency. In most designs, the seat is propelled out of the aircraft by an explosive charge or rocket motor, carrying the pilot with it. The concept of an ejectable escape crew capsule has also been tried. Once clear of the aircraft, the ejection seat deploys a parachute. Ejection seats are common on certain types of military aircraft. A bungee-assisted escape from an aircraft took place in 1910. In 1916 Everard Calthrop, an early inventor of parachutes, patented an ejector seat using compressed air. The modern layout for an ejection seat was rst proposed by Romanian inventor Anastase Dragomir in the late 1920s. The design, featuring a parachuted cell (a dischargeable chair from an aircraft or other vehicle), was successfully tested on 25 August 1929 at the Paris-Orly Airport near Paris and in October 1929 at Băneasa, near Bucharest. Dragomir patented his "catapult-able cockpit" at the French Patent Of ce. The design was perfected during World War II. Prior to this, the only means of escape from an incapacitated aircraft was to jump clear ("bail out"), and in many cases this was dif cult
jet-engined ghter in 1940. One of the He 280 test pilots, Helmut Schenk, became the rst person to escape from a stricken aircraft with an ejection seat on 13 January 1942 after his control surfaces iced up and became inoperative. The ghter, being used in tests of the Argus As 014 impulse jets for Fieseler Fi 103 missile development, had its usual HeS 8A turbojets removed, and was towed aloft from the Erprobungsstelle Rechlin central test facility of the Luftwaffe in Germany by a pair of Bf 110C tugs in a heavy snowshower. At 2,400 m (7,875 ft), Schenk found he had no control, jettisoned his towline, and ejected.[2] The He 280 was never put into production status and the rst operational type built anywhere, to provide ejection seats for the crew was the Heinkel He 219 Uhunight ghter in 1942.
