Rely on nice weather I visited on a walk Aviation Museum in Krakow, to see what's new, you can see .. Oh, and I saw a passenger plane Ilyushin Il-14, which was taken off the canopy flaps wings .. Turns out there can be visible between the ribs on the insert shapes Styrofoam quite calmly, there's nothing there, outside the free space .. judging by the number would be that of the keel cubic meters .... [/img]

And now the strangest thing .. On the screen shots from the simulator to the airfoil published by NASA, pointed red frame so strange two values that can be set on the simulator .. Namely, in terms of drag and lift. and would not have believed in their value, if not the simulator, which included such a serious company like NASA .. In the first image you can see that the drag is set to 21 Newton.Lift has until 244 Newton .... So for the help of a smaller force is a much more powerful .. Something with anything ... this force is with 11.6 times greater than the resistance (drag).

In the second figure also drag is 12 Newtons, and lift 191 Newtons .. ie with 15.9 times greater ..
I think that these simulations are accurate ..
Now, if even half of the value obtained for lift holding strength to produce the drug's effects, it would lift force will be very high ... So we use 85 Newtons of lift to overcome the resistance (drag) 12 Newtons. that is enough for us to capture power efficiency, and conversion to drag about 14%. (eg rotary vane pump + propeller). I think it is really to do with such a small sufficient efficiency .. So the system can move itself by overcoming drag and float in the air At 85 Newtons lift .. I guess that NASA is wrong ...
So says the theory .....

Here drawings like two wings facing each other bellies they give huge wind acceleration and negative pressure which we introduce inside the wings. If the wings will be mounted permanently, with sufficient clearance between them, and may be greater plenty of slots, a big part of the lift force will turn on underpressure which will be inside the wings could create a fairly low pressure and large its quantitative yield .. If so it will already know how to use a vacuum with a good efficiency, for example by the vane pump is running, vacuum-as a motor ... the motor can drive the generators or.... propeller ...

Well think again about the Red Baron. something on you tube not much you can see these vibrations..

The effect of two teaspoons on the wings of aviation profile facing each other stomachs. Wind from an ordinary hair dryer ... you can hear the clatter of high-frequency wing strokes of each other. That is, the vacuum, despite the very light wind is enormous. Disappears, as the wings come closer and then again .. Hence arises the clatter.

All of these flaps, ailerons and rudders are completely empty inside .. You have to be flame-retardant foam fill special for these air targets, and made in the form of fittings.
Clearly, the wings are half the space

Also in the hull filling soundproofing could have been a foam instead of wool.
Wool absorbs water very quickly ..Surely you would need to develop now and again a special material, teeth had been closed and not soaked with water. and was close to the damping properties of wool. It is a big challenge, but with the quantity of aircraft produced, certainly to perform .. It's just to follow in this direction

[quote="Big Pete"]There s also the issue of internal inspection of the tanks. All the regulatory authorities require internal visual inspections of the tanks and pressure testing through the life of the ship, and Ultra Sonic thickness testing of the steel plates, [color=#FF0000]how can you do any of these things[/color] if the tank has been pumped full of foam?

If the Hull is damaged and a section of damaged steel has to be cut out and new steel welded in, what happens to the foam?

Lots of practical difficulties.


It is a pity that very carelessly read my posts and you watch my pictures .. clearly wrote that it does not have to be foam, but moldings, such as in this link

Also on section plane clearly can see that but there is a lot of free The places, and not how you think you .. Here is another one photo of the crash TU 154
I think that you should carefully read my poste, and certainly you will become a proponent of my solutions, and we will not have to cry after drowning our children in the future :(

All of these egg-shaped holes, a transition service .. next unused spaces .. There are rules that from a certain size vessels must have a double side and bottom. Fill the space with Styrofoam prevent sinking ....

By education , I am Eng. mechanic. But I dealt with making the sound at concerts my apparatus .. It so happened that a few times , even ten times , I made a concert in Gdansk Shipyard Hall (which is then burned ) .
We have always had a pass to the shipyard , because the entrance to the hall was the scene from the side yard. I as the driver of the car, after a few hours of driving , I've always had a break , and my employees were unloading acoustic equipment and lined it . I have two hours of free time , and this pass, always walked across the yard and spied on how the technology of shipbuilding . Often talked with employees who explained to me the various ins and outs of building ships . Then I met shipbuilding quite accurately , because she was always very interested mechanics ... Then I came to realize concert .. With these trips , I know how much free space is on a big ship . Here I present figure of the ferry , which sink .. Knowing its importance , which is 6800 tons , and subtracting approximately 1,500 tons , steel, wood , fuel , and such a variety can displace water , leaves us to displace the water about 5300 tons. , And then ship will not drown .. an average of 5300 tonnes divided by the length of the vessel is 146 meters = one meter will fall an average of 36 tons. so much water should displace to get afloat .. Now the height of each side of the free spaces submerged to 2 x 10 meters. .. For the average 15 meters wide double bottom .. together gives us 35 running meters , part of the flotation technique around the ship ( floating section ) .. So enough that the average thickness of 1 m polystyrene foam , applied to each inner metal shell of the ship , provided the to always buoyancy of the ship .... only 1 meter thick ..


When it comes to airplanes, it also thoroughly know their structures .. In carrying about 1,000 concerts in the former Soviet Union, every change of concerts, took place only airplanes * Once was a car, but I said 'never again' J. I had to upilnowania 40 boxes with equipment weighing about 3 tons .. Always, as soon as possible, guarding the proper loading and unloading, personally entered the baggage compartments, aircraft, whom the trip was .. And these were the aircraft from AN2 to Il 82 all types which were in the Soviet Union .. So exactly what I learned there are opportunities. And I know that a lot of them too .. Especially as it applies molded styrofoam possible to remove, to do the service ..

Happy Easter for all

The plane actually has a tower of different things. plumbing, electrical .. But still has Most sending of empty unused space. . Of course you have to think 10 times, where we can insert each of 1 decimeter foam. Part needs to be done easily removable, in plastic bags or specially shaped profiles, that can be had for service to remove and after the back insert. It's a plane, one of the most complicated machines .. in addition with the high standards of reliability .. so it will not be pumping air into the inner tube ..

[QUOTE=Richard Casto;3381043]Andrew,

I subscribe to this thread and have always enjoyed your posts, so keep them going.

Regarding the use of foam to prevent aircraft from sinking when lost at sea, I don’t have the statistics, but anecdotally, I assume that most deaths are not due to drowning, but due to impact, or other high energy violent endings. I believe the scenarios you are discussing likely have adequate solutions in place (life rafts, etc.).

I think an excellent area for the use of that type of foam would be in help reduce the death toll for passenger and roll on/off ferry accidents. These seem to happen in rough seas, or in overcrowding conditions with sometimes large loss of life.


Thank you very much Richard for a good link and my subscriptions. I Normally you need only the broad outlines of the new ideas I present .. they require much development, by many people .. then they really for us is profitable ..
Such inspirational posts like yours, Richard causes that describes more about the innovation ..

Here I would like to say that the majority of pilots for emergency landing was going to make sure you water, if she was sure that the plane did not sink .. The waters, even on land is not much, for example, a lake or river. This launch is a big advantage. There is minimal risk of fire aircraft .. The most spectacular example is the "Miracle on the Hudson"
Here you can see how little is needed to plane could swim ..
