A quick look at the proposed EASA eVTOL rule

October 16th, 2018, by Ben Brelje

EASA dropped big news on Monday, announcing a proposed special condition under which electric VTOL aircraft under 2000kg may be certified in the European Union. This is the most concrete pathway to certification from a major western regulator and is sure to be followed closely by the FAA (which tends to keep regulations in sync with Europe for the most part, and vice versa). I'll take a quick look at the updated rule and identify the novel issues raised. Several of the points are sure to be contentious, and I expect the public comment period to be quite lively.

Electric Flight Roundup: More details on the NASA X-57 Maxwell

July 27th, 2017, by Ben Brelje

Well, I may have been too ambitious with the idea of a "weekly" tempo for my last blog post. So much was announced at Paris but the following weeks were slow. I've been gathering updates since then and my plan is to post when I reach a critical mass of material or when a feature-worthy development comes along.

  • More details on the X-57
  • Turbine primes throw cold water on electrification potential
  • External analysis of Zunum
  • New FACEs and fresh configurations

Electric Flight at AIAA AVIATION 2017

June 20th, 2017, by Ben Brelje

AIAA recently posted a live stream from the "Aircraft Electric Propulsion: Transforming Aviation" track at AIAA AVIATION 2017. I wasn't able to attend in person, so it was great to be able to review the panel discussion and questions.

The panel featured speakers from E/S Aero, the American Helicopter Society, NASA Glenn, CALSTART, and Zunum Aero.
