Ejection seats essays

Ejection seats essays Ejection seats, how to save your life it Although real emergency situation are rather rarely in modern aviation, the necessity of ejection seats is still given. This can be caused by many different failures or malfunctions of the plane, by errors of the pilot or simply through hostile action. Many of these situations develop rather quickly, so the time to react and, take the decision to initiate the ignition of the seat is rather short. For this reason most military aircraft, research aircraft and some small commercial planes are equipped with ejection seats to allow pilots to escape. Ejecting from an aircraft moving at speeds greater than the speed of sound can be very dangerous. The force of ejecting at those speeds can reach in excess of 20. At 20 Gs, a pilot experiences a force equal to 20 times his or her body weight, which can cause severe injury and even death. The development of ejection seats started during WWII. Germany Russian and America started researching nearly the same time. After the war Russian scientists were able to built their first ejection seat with the help of German technology they had secured from German labs. The problem of these seats was that the aircraft had to have a minimum height, speed an had to fly a stable and not inverted flight. Furthermore the pilot had to disengage himself from the seat which then dropped away in free fall. For this reasons there were a few issues who had to be solved for a save ejection of the pilot and to give him the maximum chance to survive. Lifting the canopy - Bolts that are filled with an explosive charge are detonated, detaching the canopy from the aircraft. Small rocket thrusters attached on the forward lip of the canopy push the transparency out of the way of the ejection path Shattering the canopy - To avoid the possibility of a crewmember colliding with a canopy during ejection, some egress systems are designed to ...
