Interesting, that this form-factor was popularized by DIY builders. First one was dutch-built, sponsored by Red Bull after prototyping stage, to film Verstappen's full F1 lap (so semi-DIY, so to say), but then record was taken back and forth between two DIY builders — Ben Biggs in Australia and Luke Maximo and his father Latest record by Ben Biggs was 626kph (389mph). Latest record by Luke Maximo was 655kph (408mph).

You can only go so fast with propellers, as the propeller tips approach speed of sound and then life gets complicated.

Fans are pretty much like propellers and the F15 uses a turbofan and goes supersonic. It works by inlets and exhaust nozzles that slow the air the speed it up again. The only reason that might not work on an electric drone with fans and nozzles is not enough power.

No speed is the most important factor. You have a very limited window to get the munition on target. An in Ukrainians case Geran drones drones don't maneuver much, if at all.

Speed obviously isn’t the dominating factor given interceptor drones exist in a world with rockets.

Please be serious, that's a ridiculous statements. Lasers also exists. Enough nuclear bombs could also clear the air space. Pull yourself together.

Bullets (Or rockets. Or shells with proximity fuses) go much faster so obviously speed isn't the most important factor. These are anti-aircraft interceptors , intercepting sound like a critical part of the job. > drones don't maneuver much, if at all. Yeah, drones didn't fly at 700km/h much if at all either. So can an interceptor drone traveling at 700km/h reliably maneuver to intercept an enemy drone? How well can i…

Bullets don't have the range (and energy at farthest ranges). Rockers are too expensive.

They do well with a human piloting. Do look into the subject before you barf on the keyboard.

Maneuverability and cost. Why this specific stunt? Marketing, presumably.

Maneuverability not so much modern AA missiles can pull over 60gs. That capability costs 100s of thousands of dollars though.

The inverse of cost is the potential force multiplier.

Why are you behaving so vilely?

They should look at Prantle Wing (also applies to propellers) to get more efficiency out of the design.

The weapons use saddens me. Ignoring that, this is interesting for electric aviation as a whole. One of my arguments about electric aviation is that burning fuel for propulsion has a lot of challenges, especially at altitude. Pushing the speed envelope for electric will lead to more and more novel ways of pushing things and once they get efficient, fast and, very importantly, high altitude, the amount of power you ne…

FL1000 is likely not possible using electricty. Electric power is converted into thrust via propellers pushing against a working fuild (air). The less air at fl1000 means less working fluid. A combustion engine adds to the air, generating thrust not just by propellers but through rocket forces: heating the working fluid and ejecting it at speed. To do that with electricity one would have to convert the electricity in…

Electric systems are 100% efficient at heat generation.
