Hello.
I have been a member on this forum for quite some time and I came here because I've always had an interest in science, particularly physics. When I was in Junior High, I did very well in my science class but by the time I got to college, I wanted to make money. However, I realized that...
Ah, so that's what I wanted to know. As you said, if you were to reverse the rotation, there would still be an imbalance, in this case, if the rotor rotated from the left to the right, at 9 o'clock it will create more lift, but at 3 o'clock it would reduce the lift, correct?
I'll admit I am somewhat confused because I am attempting to understand why on the left rotor the speed is less. I get that the left side of the blade is the retreating blade because it is moving away from the helicopter, but if you were to move the retreating blade in the opposite direction...
Interesting comparison! So, what would be the case if the blade was rotating from the left to the right?
* Note: I flipped the image in the opposite direction for you to see.
Well, from what I understand is the blade tip at the 3 o'clock reference equals forward speed and the blade tip at the 9 o'clock reference equals negative speed, correct?
In a previous thread, I brought up the topic of Airwolf and the wonderful people here have explained why it is impossible for Airwolf (or any helicopter) can't fly at supersonic speeds.

In Sci-Fi Channel's "Dune", there is a scene in which the Fremen attack Gurney Halleck and his men in a really cool fashion: They pop up from the sand and attack them.
Here is a clip of that scene:
I would imagine that for this to work, an oxygen mask would be required, at the very least...
I've been a Knight Rider fan since I was a kid. One of the coolest features of K.I.T.T. was its ability to turbo boost over obstacles. Now, the kid in me says, "Cool", but the adult in me says, "I very doubt that would work in real life". Years ago, I bought a die-cast model of K.I.T.T. equipped...
