How to pronounce “propeller” in English

you know we've been working on this for a long time it's not not like we haven't been trying to build commercialpropellers but the pressures on the industry now are greater than they haveever been um because um the sh the global shipping industry has to come

linear relationship and um that it has to do with variable there's a kind of propeller called variable speedpropellers that are in some kind of use and you know so uh it's just not a completely direct relationship otherssay that overarchingly and I think that's some of the statements that are in the film I think are they're hard one

the thin doors of the plane shut but rattle conversation isn't possible boards are stuck directly into thepropellers you are forced to listen only with your eyes as they sweep across the landscape when you look down the viewappears less like a picture on television and more like the opening scene of an IMAX film the earth moves beneath the plane like the ocean rushing

Did you find yourself, at any point when doing these simulations, doing these equations, coming to basically a roadblock where you said, OK, and with this,the propellers have to weigh negative 5 pounds a piece.Did you find yourself at any of these places where the numbers didn't work, and you had to back up and change?

and West Africa and all the rest to the US?And in our little propeller plane, who here is a pilot?Come on. Who here is a pilot aspirant?

efficient quieter ship propellers for the commercial traffic um yes I mean the efficiency ofa of a commercial propeller has been something that the shipping industry and in in a lot of our meetings has said weyou know we've been working on this for a long time it's not not like we haven't been trying to build commercial

You're not going to like this word.You wear the propeller hats at the birthday parties.

It's like playing with Legos. Legos are the crafts of old dead people. Here's another example. Here's a guy with a little motorized bike. And maybe I want some kind of sailboatwith a propeller on it. Look by the windmill. How about a Sears catalog full of gears and gizmos and sprockets?And you take them all apart and put some other things together and now you got this guy.

are some of the things we have to get at um for chronic influence so is anybody designing moreefficient quieter ship propellers for the commercial traffic um yes I mean the efficiency ofa of a commercial propeller has been something that the shipping industry and in in a lot of our meetings has said we

utterly depends on microbes to complete its life cycle these little tubes are very tiny but they can get so dense thatthey clog the propellers of ships and underwater surfaces they are created bya small marine worm that worm can only make the tubes if it becomes an adult and it can only become an adult if it

And in the '50s, the United States Air Force had this really serious problem, which is we had just gotten these jet powered planes.We went from propellers to jets that go the speed of sound.And they had enormous performance problems.

That's how you get 80% of the thrust.It's basically a huge ducted propeller.So, why do it this way?

We also see fully-- Oh, sorry about that.Here's a ship's propeller tangled with a netting.

efficiency and this quiet at the same time it's the cavitation that's the problem that causes the noise and causesthe loss of efficiency of the propeller exactly it's interesting I I I have to tell you that there would be othervoices up here who would be from the industry who would be saying it's nowhere near that simple there's whole

voices up here who would be from the industry who would be saying it's nowhere near that simple there's wholesectors of shipping um and and propeller use um that have to do with which engineis is paired with which propeller um that would say that it's not a um direct

and they would when they would tow this thing around they would put a fake propeller on the front because of coursea jet could not fly without a propeller but a landscape had to be created forthis secret jet fighter if they were going to build it they needed to have a secret Factory they built that in

The client left the court knowing that he could not survive one more day in Chavez's Venezuelaand very fortunately managed to equip himself with a very small propeller driven device, travel for threehours over the ocean-- managed to get to curacao, where we had a jet ready to take him to the United States, where he has now

to do with operations so it's this it's this tripl link thing it's it's the propeller design linked to how the hullis built in in in in combination with the propeller design and then the third component of is it actually going to beused to the design specs that will result in the efficiencies that that it

used to the design specs that will result in the efficiencies that that itwas built for but I thought the issue with propeller design you got theefficiency and this quiet at the same time it's the cavitation that's the problem that causes the noise and causes

We said, let's do nature.And we saw their new prototype where the propeller was moved from the back to the front of the plane.

at home. This is called immersion recirculator. It's basically a piece of fancy lab gear that keepswater at a particular temperature and it's got a little propeller that agitates it, moreon that in a little while. But the eggs themselves work out really, really well this way. Think about the temperatures that are involved in egg.

rotate. So they can fly as a propeller plane um here or a uh a cheapman's jet

relatively large one that we that was spoken about a little bit in Germany but there that's where most of that designwork has been and it's usually on the combination of the hull and the propeller and then there it always hasto do with operations so it's this it's this tripl link thing it's it's the propeller design linked to how the hull

secret project uh called project XP 59a for the was the first jet fighter rightand they would when they would tow this thing around they would put a fake propeller on the front because of coursea jet could not fly without a propeller but a landscape had to be created for

But the reason we think this is so effective is that the propellers make a sound very similar to the frequency of swarming angry bees or hornets.

people not liking professors and pinheads and you know, the guys in propeller beanies and all that. What will push me to write it

work has been and it's usually on the combination of the hull and the propeller and then there it always hasto do with operations so it's this it's this tripl link thing it's it's the propeller design linked to how the hullis built in in in in combination with the propeller design and then the third component of is it actually going to be

is is paired with which propeller um that would say that it's not a um directlinear relationship and um that it has to do with variable there's a kind of propeller called variable speedpropellers that are in some kind of use and you know so uh it's just not a completely direct relationship others

If I drop it, it's gonna get sucked into the propeller and the motor's gonna go kaput and I'm -- you can see I'm really far away from the

plane that is a hybrid between a helicopter and a jet. And so the propellers on the plane are able to

So through stitching, it makes the drone itself and the propellers completely invisible in your final footage.

For example, humans use rotary motion for all sorts of things from propellers to wheels whereas nature prefers legs, wings, and fins.

so wealthy by this point, that he could build giant machines.And he had a hanger out there near London where he was building his experiments and he built multiple propellers to see which would work the most efficiently in the air.And he is really dedicated to solving this problem. This is a latter-day artist's representation of what happened on his most successful, and last, flight.

components of the airplane. They didn't invent the wheel. They didn't invent the propeller.

different numbers of wings, different shapes of tail planes, different places for the propeller, et cetera.

It used to be that you would go to one type of an operation to fly and maybe via flight instructor and small single engine propeller flights for a while.

David Malki: So he made it. That's the thing. He made it horribly uncontrollably, but he made it. This is what he says about the accident."I found myself floating in the air with the feeling of being in a boat, but unfortunately, a piece of the broken plank struck one of the screws, the propellers, and smashed it.I instantly shut off steam and the machine came to a state of rest on the earth, the wheels cutting deeply into the ground and leaving no track, thus showing that they had
