targets

ATI’s 2026 Target Matrix vs the 2021 NASA Baseline Back in 2022 we covered NASA’s targets for electrified aircraft propulsion, which were deliberately broad: a single system level specific energy figure of 400 Wh/kg, a general expectation of “1000’s of cycles”, and a note that power demand would spike hard during takeoff and landing. That … Read more

A look at the electrified aircraft propulsion targets. NASA state in their November 2021 presentation that they have the following requirements for the battery pack: The targets at pack level are rather tough: The gravimetric energy density plotted versus total pack energy shows that the automotive packs are currently plateauing around 180Wh/kg. The roadmap to … Read more
