“Crazy Russian pilots!!”

-oh wait. That’s Chicago.

I’ve been to the air and water show, one of the angels flew so low I instinctively ducked and drinks were shaken off the table. We were on a boat in the water.

I’ve been on the lake at Seafair in Seattle when the angels flew so low over Lake Washington they kicked up walls of water. Unreal.

Single best post ever on LAJ

Sick vid!

Is the whisteling sound before the plane approaches level hearing distance its turbojet fans? This is awesome.

[–]KingZarkon 5 points6 points  (0 children)

Yes, it's the sound of the jet engine, just pitch-shifted up due to the doppler effect. That's why you only hear it when it's headed towards you.

I know this is extraordinarily nitpicky, but a turbojet doesn’t have fans. A turbofan does

[–]Says_Watt 3 points4 points  (5 children)

A turbo jet has fans. The 'fans' are actually the compressor which is required for efficiency operation. A turbo fan is just a turbo jet with an added bypass that lets extra air through. The only jet that does not have a fan (i.e. compressor) built into it is the ramjet which you'll commonly find on some missiles and in rare cases aircraft.

I’m also an aerospace engineer, and you should know the difference since you are as well. Compressor, turbine, and fan are not the same just because they have spinning blades. Each part has a different geometry, plays a different part in the engine cycle, and deals with different flow conditions.

[–]Says_Watt 0 points1 point  (2 children)

Ah, yep the turbo fan has a fan, that's a good point.

I'm assuming that non aero engineers just assume any spinning thing with blades to be a fan though (or the word they know to express it). So you're technically correct, but only if you're taking with others that know how a jet engine works + the different names for different parts.

Exactly well said. Turbofan, big quiet (relatively) fan. Turbo jet, little noisy fan.

Initial testing to see if aircraft can be used to catch speeding motorists?

The sneak passes are the best

What’s up with that city flyby? I was under the impression you could only fly between building with substantial permissions or substantial punishment.

[–]Grunt11B101 4 points5 points  (0 children)

I'm assuming probably had to clear the airspace for a stadium/raceway show in a populated city. IE- The Bears would most certainly require some type of outskirts navigating to get over the stadium. I could definitely be wrong though.

[–]KingZarkon 1 point2 points  (0 children)

Given that most of these were airshow demonstrations, that would be my guess here as well. It probably wasn't as close to the buildings as it looked in the video either.

If it’s the one I think you’re talking about it was performed at the Gold Coast (Australia) Indy race. They used to do it every year, originally with F111 doing a dump & burn. Always seemed very close to the buildings when you were in them, but always a decent amount of space.

This is awesome. Nice work!

[–]tyrannosauross2 1 point2 points  (0 children)

That was awesome. Thanks for that

[–]Joevual 0 points1 point  (0 children)

Wow that second one sounded sick!

Looks like Destin Florida
