FIGURE 1 shows a block diagram of a non-limiting example of a dual mode ejection system 20. The present invention allows selection of one of two modes of ejection: ejecting through the canopy and jettisoning the canopy before ejection. Therefore, there exists an unmet need to allow a customer to select and operate an ejection system in its preferred format without incurring great production or alteration costs.ĭETAILED DESCRIPTION OF THE INVENTION The present invention provides a method and system for ejection operation in an aircraft. The customer can not easily alter the aircraft to allow for a different ejection method. Also, once a canopy system is installed in an aircraft, the ejection method is set. This greatly increases costs over a common design aircraft that has not been modified. Because of these desires for two different ejection methods, two separate canopy systems are manufactured. Air Force prefers jettisoning the canopy prior to seat ejection. The quickest ejection method is ejecting through the canopy. The Navy and Marine Corps traditionally favor ejecting from an aircraft as quickly as possible because of the hazards of carrier operations. One example of further modification of the common design is an ejection system for emergency escape from an aircraft. The Navy, Marine Corps, and Air Force further modify the common-design aircraft.
