The latest addition to the UTC Aerospace Systems family of Advanced Concept Ejection Seats, the ACES 5® incorporates significant safety and cost saving upgrades. Engineers have combined the unparalleled spinal safety performance of the ACES II® ejection seat with next-generation head, neck, and limb protection for all aviators. They have expanded the height and weight capacities for the seat so that the U.S. military can safely eject the broadest range of male and female aviators ever.
Imagine you are piloting a B-2 Spirit a few years from now. Your bomber has experienced some type of catastrophic damage or system failure. You assess the situation—it’s clear that the aircraft is no longer flyable, and you and your co-pilot need to eject. You feel confident because of the trust you have in the ACES 5® ejection seat you are sitting in.
As you read this sentence, you are experiencing life at 1 G—gravity is pulling down on you at 32 feet per second squared. If you happen to be flying some aerobatics and executing a 3 G barrel roll right now, things are different. At 3 G’s, you’re feeling triple the pull on every pound of your body and whatever is attached to it. That means a 150-pound airman with 50 pounds of flight gear would experience 600 pounds of force. During an ejection, you would experience at least 8 G’s of force on your body. An additional ejection hazard is wind blast -- the magnitude of which approaches that of a Category 5 hurricane.
