Well in my engine variable compression ratio is feasible only for a single device in all cylinders ..
But maybe for the help of such a device could still improve valve timing ?

Here the Czech bike .. as you can see you can .. My little energy will be more efficient, but the control sytem "bike can do similar....

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 )
http://pl.wikipedia.org/wiki/Po%C5%B...Gda%C5%84skiej .
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

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

So they go on the road foam, administer (at least for ships) foam glass, which is maybe a little heavier than styrofoam, but it resists 600 degrees Celsius temperature ..

to get the buoyancy as the ferry Sewol, it would have to be about 800 tonnes of such glass foam .. the same as the volume of polystyrene...

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

Talk with plenty of foam.

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.

No Bocolo, this film is just a demonstration, designed to show that between wings have been observed even small wind evolves very large force, which causes a vacuum. . It falls, but sparkled with momentum hits for himself .. because a large force was driven to such behavior. Of course, between the wings should give solid struts, which will determine the distance between them, chosen in the laboratory and Unclassifiable biggest Underpressure .. Then the vacuum should enter into the slit inside the wings of NACA FELIKS and further from the center of the wings for the help of some pipes, where we will be the most comfortable .. Of course at the end of the pipes have to give some engines vacuum, for example, a simple turbine, or a vane pump working as a motor ....
