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

Razor blades. Ahhah.

Ladies razor blades.

Schutz, fetch my blades.

Crossing blades with a pirate?

freddy krueger have four blades, man.

Blades are simple, untraceable and effective.

You can measure the aerodynamic forces it's creating.

and He made them like green blades devoured.

And grains in the blades, and fragrant plants.

No blades, no zip guns, no tire chains.

The flat sharp edges are like knife blades.

Also, we see how we measure the aerodynamic efficiency.

Also, we see how we measure the aerodynamic efficiency.

In the first flight, no aerodynamic control of the vehicle.

In the first flight, no aerodynamic control of the vehicle.

And I bet you forgot my razor blades, didn't you?

They might attack you Killer Blades unless they know you're coming.

I wanted to ask you if you've got any razor blades.

CA In fact, a design of the windmill that was in the book, it has got four ah three blades, and mine has got four blades.

Notice, too, that the knife blades are both pointed toward the plate.

No matter who finds him, the Killer Blades or the Golden Bows.

WK I made four blades, just because I want to increase power.

Only if you control and regulate it, you will get that aerodynamic efficiency.

Only if you control and regulate it, you will get that aerodynamic efficiency.

I felt the railing pressing against my back, just below my shoulder blades,

Of breaches, ambuscadoes, Spanish blades, Of healths five fathom deep and then anon

We had knowledge about the electromechanical efficiency and then we can calculate the aerodynamic efficiency.

We had knowledge about the electromechanical efficiency and then we can calculate the aerodynamic efficiency.

And in the second flight, three minutes of fully controlled, aerodynamic flight at Mach 20.

And in the second flight, three minutes of fully controlled, aerodynamic flight at Mach 20.

64 meter wingspan to carry one pilot, the batteries, flies slowly enough with the aerodynamic efficiency.

They use no chainsaws or anything it's entirely just blades, and an incredibly efficient process.

Grab the blades in mid air, land right there in a pool of blood ... (Laughter)

Oh, yes. You can get me a dry Manhattan, and a packet of razor blades.

The American munitions are more aerodynamic and has a propellant that burns faster the results are dramatic.

By the way, Smith, I seem to have run out of razor blades for some reason.

So the guy... took the tip of the blade... stuck it in his own shoulder blades.

So you may have six, eight ten little particles of the bullet that are like razor blades...

You wish to make sure that a helicopter can be recognized, no matter what angle it's rotor blades currently have.

And so in the second flight, we were able to get three minutes of fully aerodynamic control of the vehicle before we lost it.

And so in the second flight, we were able to get three minutes of fully aerodynamic control of the vehicle before we lost it.

And we tackle this problem by building giant, dynamically scaled model robot insects that would flap in giant pools of mineral oil where we could study the aerodynamic forces.

The way you normally build a system right now is you have a tube stack that has to be launched from the ground, and resist all kinds of aerodynamic forces.

You put these two things together, the net result is that all side forces on the glass are small and are mainly dominated by aerodynamic effects, which at these speeds are negligible.
