Civil Vertical Propeller

Cockpit, propeller, engine.

The agitator is inclined to exaggerate trivial matters.

No epaulets, a soldier's overcoat. A political agitator?

The net got entangled in the propeller.

Jet planes fly much faster than propeller planes.

Wanted to know what it was like to walk into a propeller.

Cancel that pitch for the electric saw thing with the propeller, all right?

And despite the aerodynamic interactions with these propeller blades, they're able to maintain stable flight.

That's nothing new that's a propeller clock that's the rims that you can buy for your car.

And they've already found that by being more intelligent about better propeller design, you can reduce that noise by 90 percent.

If I wind this up and then let go, why doesn't the propeller stay still and the body of the plane spin around?

You're not powering the propeller, you're powering the wheels. And it is under seven feet tall, so it will fit in a standard construction garage.

Hexacopters and octocopters, with six and eight propellers, can provide redundancy, but quadrocopters are much more popular because they have the minimum number of fixed motor propeller pairs four.

Conventional wisdom says that you need at least four fixed motor propeller pairs in order to fly, because there are four degrees of freedom to control roll, pitch, yaw and acceleration.

People have been struggling for years to try and design a very fast rotating boat propeller that doesn't cavitate and literally wear away the metal and put holes in it, just like these pictures show.

If we could have the second video, the one minute, put in as quickly as you can, which this will show the Pathfinder airplane in some flights this past year in Hawaii, and will show a sequence of some of the beauty behind it after it had just flown to 71,530 feet higher than any propeller airplane has ever flown.

I was afraid that they would kill us, and instead they understood, especially when I told them that I was trying to apply the same stratagem that Philip Johnson applied in 1934 when he wanted to make people understand the importance of design, and he took propeller blades and pieces of machinery and in the MoMA galleries he put them on white pedestals against white walls, as if they were Brancusi sculptures.
