I think a time warp of the head of an RC helicopter would look great. There are a lot of moving parts rotating around 3000 RPM. Each revolution each of the 2 main blades changes pitch 4 times a rotation (positive, flat, positive, and then flat again), that's 12000 movements combined each minute!1 We are not even talking about the fly bar, which does the same thing separately now that makes 24000 a minute!!!
Those parts are constantly moving, and if you have ever seen and heard an RC helicopter fly, then watching it in super slow motion would be awesome. I'm sure a lot of viewers would love to see something like that.
I looked at that vid clip of the camera looking down the rotor blade and i can tell you from being in the navy for 5 years as a helo mechanic that the bird it was on was a rigid blade. now if they were to do that on a black hawk thatwould look completly different as if you walk down the top of the blade the tip cap will touch the ground but would diff be cool the catch at 5000 fps.
I have to agree about helicopter flight in general. The problem would be that a full size heli would be hard to shoot. RC Heli would be the next best process. RC & Full size share the same mechanical design, the biggest difference is the weight to lift ratio. That is why the RC can preform the fancy tricks.
The main rotor blade will have a lead / lag effect as it is spinning around, while the tips of the blades should be nearing or breaking the speed of sound.
Helicopters fly on a bell shape of air while in hover or motion. Because of the bell shape of air running down through the blades, pushing to the ground, then rotating upwards is all theory.
Time warp could use that special camera to see if they can see that actual flow of air being pushed down to the ground while in hover from the blades, then prove if the air does circle around an get pulled back in again.
