  • @DarylFosterPuttPutt4Video
    @DarylFosterPuttPutt4Video  12 лет назад

    Thanks for watching and commenting. That probably has some effect. There is quite a lot of speed variation during a test that goes in to arriving at the average speeds quoted so the attachment is not the main speed limiter. It would be nice to be able to test in a straight line with ideal conditions and eliminate the drag of turning.

    @kevro5967 6 лет назад +1

    You should try to determine what is different when the engine "over performs", and then try to replicate those conditions until you achieve a steady result between runs. Measuring more variables, like water & ambient air temperatures, or using a graduated syringe to measure exactly how much water you put into the engine, and then adjusting that volume accordingly. Finding whatever it takes to get the best performance each time will give your expirements more control.

    The statesman and scientist Ben Franklin performed similar experiments to determine the best shape that would result in the greatest efficiency for canal boats. Penn State University runs a giant "water tunnel" that fill a building. It's fine to make hydrodynamic calculations, but they still test profiles in water for real-world results. Nice work.

  • @ppplll000999
    @ppplll000999 10 лет назад

    I have questions 1)What is the experimental result if you use just one single jet tube. 2) What would you think happen if you use 1 tube in front to intake & 1 jet tube behind after adding one-way valves to direct the water. 3) Do you think a CONE shape boiler can provide better jet.

    • @DarylFosterPuttPutt4Video
      @DarylFosterPuttPutt4Video  10 лет назад +1

      In theory one tube should be very good. In practice it is very temperamental. Number of tubes, size of tubes, length of tubes are all interrelated. 2) I think it works but not as good. 3) No. Thanks for watching.

    @welshpete12 8 лет назад

    Beautiful made models ! I know nothing about this form of propulsion. But wouldn't making the " engine", and exhaust bigger improve performance ?

    • @DarylFosterPuttPutt4Video
      @DarylFosterPuttPutt4Video  8 лет назад

      +welshpete12 Hello welshpete. Thank you. Unfortunately these engines do not scale up predictably. Some very large engines have been built but the performance has been dismal. There is a video on my best engine which is larger.

    • @welshpete12
      @welshpete12 8 лет назад

      +Daryl Foster Yes I can that must be true , If not, they would be a common means of propulsion today . They seem to be very similar to the engine used in the V1 German weapon of the second world war . Do you think that could be the way forward ?

    • @DarylFosterPuttPutt4Video
      @DarylFosterPuttPutt4Video  8 лет назад

      +welshpete12 There is a similarity to the V-1 rocket which is a pulse jet and has undergone considerable development. You can search RUclips for videos if you like and see results that are amazing. Both engines are poor re efficiency so that makes commercial use unlikely. There are a couple of differences in the two engines. Pop pop engines do not require any movable parts. Though if equipped with a diaphragm which moves that does not affect its ability to run and in fact reduces the power. Also the pop pop is an external heat engine while the pulse jet is an internal heat engine that usually uses some moving parts for sustained operation. Significant future development seems unlikely but who knows.

    What if you made a slightly curved hull, like a banana, that matches the pond circumference?

  • @DarylFosterPuttPutt4Video
    @DarylFosterPuttPutt4Video  13 лет назад

    @TheDownloadfreegames Interesting thoughts. Some technical difficulties arise. The curves, length, diameter and quantity of tubes affect performance. Too many tubes bent into a boat shape would not likely be a better or lighter boat.. Drag from irregular hull shape and weight of method used to keep the tubes joined and watertight likely more than as done now. Like your way of thinking though.

  • @DarylFosterPuttPutt4Video
    @DarylFosterPuttPutt4Video  12 лет назад

    Proper tube length is determined by tube ID and testing. Lots can be outside of the boat to get C of G correct. Either the tubes are outside or the boat is longer which adds more drag and weight. The steam has to cool and condense long before it reaches the end of the tube or the engine will not run or soon stop running. Reading about how a putt putt engine works will help you understand why. Thanks for watching and the comment. PP4V

    • @DarylFosterPuttPutt4Video

  • @AngelLestat2
    @AngelLestat2 12 лет назад

    you measure almost the same speed in all, but I see you're using a string attached to the boat centered in the pool so they can turn.
    And I think in this way, the faster a boat goes, more line resistance will find.
    By that reason all speeds looks similar. Well, that is my opinion. Nice models.

    @laranjo123 The design for building these boats out of one piece (mostly) of flat aluminum is basic. For a new boat it is only a matter of changing the measurements for LOA, beam and displacement etc. to get what I require for a new boat.

    If the boiler pulses, then you could have an "intake" with a check-valve to replenish the water lost to thrust. Of course you would need to heat this new water with another candle.

    • @DarylFosterPuttPutt4Video

    • @DarylFosterPuttPutt4Video
      @DarylFosterPuttPutt4Video  9 лет назад

      +TIMEtoRIDE900 The water works like a piston alternately sucking and blowing. All the water is not ejected if the engine is running properly so in theory it could keep running as long as the heat was right.

    • @TIMEtoRIDE900
      @TIMEtoRIDE900 9 лет назад

      Thanks for the explanation - - so it runs indefinitely, until the candle is done ??
      Why so many tubes ?? The tubes need to be water cooled ??

    • @DarylFosterPuttPutt4Video
      @DarylFosterPuttPutt4Video  9 лет назад
