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 first 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 Office.
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 difficult due to injury, the difficulty of egress from a confined space, g forces, the airflow past the aircraft, and other factors.
The first ejection seats were developed independently during World War II by Heinkel and SAAB. Early models were powered by compressed air and the first aircraft to be fitted with such a system was the Heinkel He 280 prototype jet-engined fighter in 1940. One of the He 280 test pilots, Helmut Schenk, became the first 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 fighter, 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 snow-shower. 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 first operational type built anywhere, to provide ejection seats for the crew was the Heinkel He 219 Uhunight fighter in 1942.

The invention Ejection seat, issued on 2 April 1930,  was a new system of parachuting from the apparatus for air locomotion, each passenger having his own parachute that allows, in critical moments, the assembly detaching from the plane, so the parachute with seated passenger passes through an opening.
and the patent require that this set of cell-parachute to have more controls, operated by the pilot.

This invention,Ejection Seat(1929), was "a new system of parachuting from the apparatus for air locomotion, each passenger having his own parachute that allows, in critical moments, the detaching of the whole ensemble from the plane, so the parachute along with the passenger installed in the seat go through a opening in the floor" and the patent require that this set of cell-parachute to have more controls, operated by the pilot.

Ejection seat is an invention created by anastase dragomir in 1929 . There is a society " martin-baker" which is the principal society for creating ejection seat nowadays .
That invention is used principally in military for saving the injured in the wars

One photo from your team is ok but you have one more suggestion from admins that is more clear. So, you have to vote here in pablet among these two photos so that we have your final choice for the timeline. One photo from your teams collaborative work (Zoe's editing Iulian's photo) is added in dotstorming. Description for the timeline is ok from Andriana's post

The invention of the ejection seat, by Anastase Dragomir (invented 2nd of April 1930) was a new system of parachuting from the apparatus for air locomotion. It lets each passenger have his own parachute that allows (in critical situations), the assembly detaching from the plane. The system is controlled by the pilot.
