The propeller.

Civil Vertical Propeller

Cockpit, propeller, engine.

Propeller cavitation, deep and slow.

Look at how you mended the propeller.

Highspeed propeller effect, all on starboard side.

I tell you she's thrown a propeller blade.

You're not powering the propeller, you're powering the wheels.

In 1855, the first iron propeller driven ships were ordered from England.

This motor drives the motion of the filament, which acts as a propeller.

In order to bank, one propeller spins slightly faster than the opposite one.

Problems with propeller fouling, blocked intake pipes and damaged drive shafts have been reported.

When the engine catches, don't move, or you'll get a mouth full of propeller.

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

The Propeller Banksia ( Banksia candolleana ) is a species of shrub in the plant genus Banksia .

United Nations military observers observed a light propeller driven aircraft circling low over Tuzla airfield.

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

A propeller is a type of fan that transmits power by converting rotational motion into thrust.

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

Newton's third law tells us that the air applies in an equal amp opposite reaction force on the propeller.

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

They can teach the vehicles how to switch out their old batteries for new ones automatically. ors stop propeller from swinging.

He was running away from the police, and they cornered him at the airport and he ran into the propeller of a plane.

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.

Initially, many different designs were considered, including an unconventional project with two main rotors, placed with engines on tips of wings (in perpendicular layout), and with an additional pusher propeller on the tail.

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.
