Your browser can probably provide a reasonable translation on demand from a nearby service. FF on Linux does, so surely whatever you are rocking can manage it too.
There are lots more options.
They talk about reducing skin friction drag but due to the translation I'm not sure if that's what this article is referring to as well.
- The 43% is peak drag reduction in the transition zone only, the bit between laminar and turbulent flow, not across all flight conditions.
- Aerodynamic drag is one part of fuel burn, not a 1:1 proxy. There's also engine efficiency, etc.
- This is skin friction drag on a wind tunnel model, not a full aircraft which has extra bits like windscreen wipers.
I still think it's exciting but I reckon fuel savings would amount to a few percent (aeronautical engineers, please correct me if I'm wrong).
