Tak , eleganckie wodne porty lotnicze . Oczywiście w przenośni .ale zamiast awaryjnie lądować na ziemi , wielu pilotów by się decydowało lądować na wodzie, gdyby wiedzieli ,że samolot nie zatonie. Być może ten TU -142 tak wylądował , tylko zatoną ,zanim przyszła pomoc . Na Hudson pomoc zjawiła się 3 minuty, dlatego wszyscy przeżyli . Ale czasem na pomoc , przychodzi czekać dobę... i dlatego ważne jest żeby sobie nie zmoczyć nóg i nie dostać kataru.Woda ma jedna zaletę , mianowicie, że pas lądowania jest równy , a na ziemi różne niespodzianki w postaci większch kretowisk, krzaczków i rowów melioracyjnych...
Także możliwość pożaru jest dużo bardziej ograniczona.
Także ewentualne koszty poszukiwań o wiele mniejsze ,jak wiekszość części pływa na powierzchni.
1% ciężaru to prawie tyle ,co błąd ważenia .
Dzięki za pomoc
Andrzej

Interpreting Andrew's idea -he thinks that making airplanes unsinkable would encourage the pilots to seek emergency landing on water. Hudson was exception when help arrived in 3 minutes, but in remote areas it takes a day for the help to arrive.
Water doesn't have unexpected obstacles like the land do and danger of fire is much lower. Would adding 1% of the weight for the foam be worth it?

The wings contain fuel, there's no unused space at all in a airplane.
I see a few places where you can be put the foam.....





1% of the weight is almost the same as error weighting.

Straight structure of dynastarter brought the thought to mind for me in order on the similar principle to do electric brakes and the electric assisting engine on the not-drived pivot of the car .
Instead of the flywheel I used the brake disc from one side having small teeth made an incision.

They are also put on the PCB plate green "pins" in the bulk. http://www.new4stroke.com/greenpin.jpg



Such an arrangement allows on not-drived pivot to carry the electric brake out also. Yeah but very much work opportunities of such an arrangement are also an important case on not-drived pivots, as the electric motor driving wheels directly. Perhaps it won't be such an excellent drive as classical 4 x 4, but in critical situations can replace such a four-drive arrangement. I think that it is possible to name him 2 + 2.

And have a electronic lock.... simile ABS

I very much apologise, but I forgot that on this forum the part of readers had motorbikes......

I propose for them 1+1 system ........

Regards Andrew

Ps.In good taste there would be a use microstepper elctronic for the fluid movement ...

Maby to cover the oil tanker with the “small duvet” for providing him unsinkable ?
The duvet would be made from sea containers filled up with foam, for safety ship.
If she was “too cool”, it is possible to do it her two-tier. Places aboard of oil tanker it is relatively much.
Duvet:


And Tanker:

And about half rotate.




Star engines were characterized biggest always force density





Below picture of the star half rotate around 10 (40) with "cylinders". for the transparency of the picture one can see only 3 additional "cylinders" more than is at the animated film.
One can also see dimensions of the whole of the engine in the assumption that every cylinder has such dimensions for the picture half rotate with the set connecting rod of the Sulzer D= engine of 900 mm and stroke 2500 mm .



So 10 (40) "cylindrical" engine half rotate about the same working capacity in comparing to the Sulzer 10 engine cylindrical on the picture below .

Sulzer: 10 Cylinders 20 m long , 15 m hight , 1500 Ton weight

Half rotate star : 10(40) "Cylinders" 4,5 m diameter , 4,5 m long
about 70 ton weight.





And most importantly.. Since in the engine half rotate mass innertia are several times Sulzer smaller than in the engine, engine half rotate can work with the much greater rotation speed.
Slzer : 102 RPM 60 000 KW

Half rotate 250 RPM 150 000 KW

In same intake work volume .

Regards Andrew

Sure the engines of cars will be similar proportions

Usually from the other side flywheel a clutch is found.. it unfortunately still has a few defects. That is, relatively frequent exchange of the clutch disc, of impression with the spring,and of clutch bearing. it is one of service major repairs. , Mechanical or plumbing steering also often makes his correct action impossible

I thought, that if only an electric current decided on these all cases, it would be perhaps better. After refining details, the clutch without no service work could in order to work through the entire life of the car.
In order to carry the full function of the clutch out, he belongs, so as in previous of my proposal dynastartera, to use "green pins" and radial teeth the flywheel.
http://www.new4stroke.com/greenpin.jpg

Additionally, one should put two (or more) locks, which will steered will be a solenoid, and a spring to enter teeth on the flywheel and to close the clutch mechanically with this flywheel

So that this closing proceeds in a "stress-free way", one should add the electronic sensor which he will be detecting, or the flywheel in relation to the clutch isn't already rotate, and it is possible to put down solenoids controlling locks so that they connect on "hard" these two parts .
It is supposed to be similar acting to the synchronizer of the gearbox

Before the dismissal solenoid,, "green pins" must have the maximum electricity which with pressing a clutch pedal will be reducing. Of course this electricity and steering must reach the clutch through of collector rings, since the clutch is turning.

I think that after good designing and making such a clutch, we are having a chance to the clutch for entire living of the car

Sure the engines of cars will be similar proportions

"Half rotate 250 RPM 150 000 KW "

But we only need 60 000 KW What doing?

Yeah so ,we will reduce dimensions half rotate some 2,5.
This dimension are ~~ 3 m dia and 3 m long 40 ton ......

But it then again will give us the possibility of increasing RPM Maybe to 400 RPM?

And next reduce ..... where are border this steps ???

Border is are very small engine

They want to cultivate the Christmas Eve, going behind the tradition in Poland which is telling us that on this special day one should be reconciled with all people which are surrounding us. My wishes of the vision Merry Christmas and modified return to sources that is poped valves.
I think that with traditionalists an approval will also take place in this special day.

My proposal it is modified poped valve which let for very effective picking up the warmth by chilling with intense stream of oil.
Thanks to widening the leading part of the valve to the maximum dimension which can only to fit in the nest , the surface of the joint of the valve with the head repeatedly was increased.
Thanks to widening the leading part of the valve to the maximum dimension which can only to fit in the nest the surface of the joint of the valve with the head repeatedly was increased. much simpler sailing across the warmth causes it to the well chilled head. a here also omitted Valve Guide which is usually of materials worse being a heat conductor than aluminium stayed. the additional crack of the baulk still became the Valve Guide to head liquidated in this new structure of the valve. The new structure allows to move heat to the head very efficiently. with valve quide omitting, and big relatively with area.
In the new structure it is an important thing, that inside valve on 3 / 4 one's length is feeling empty inside and has the enormous area for the exchange of the warm with chilling oil.
Chilling jst oil passed to the middle of the valve with the help of two tubes from which the very intense stream of cooling oil is flowing out.

I think that at such a construction of the valve, the temperature of the valve should not exceed 500 degrees Celsius, and NOx coming into existence in a combustion chamber can be limited about about 80 %

It will also be possible to increase the efficiency of the engine by increasing the degree of tensing, or else there will be no great temperature in a combustion chamber what the significant reduction of self-ignitions will cause, and will cause more laminar burning.

And the most important case. Since temperature of the new valve on 3 / 4 his lengths she should not be bigger than the temperature of the head, it will be possible to resign entirely from devices for placing valve clearance, since the sum of the expandability of the new valve and the expandability of the head will be approximately similar.

therefore keeping valve clearance of manner will be unnecessary as a result of the same complete expandability of the valve and the head.

Below I am describing two models of the latest version of valves, and the disintegration of the temperature on the length in the traditional valve.









Marry Christmas Andrew
