    At Hamilton Standard we used the compressor exit temperature, and absolute pressure, the airflow and fuel flow to compute the turbine inlet temperature, knowing the combustion enthalpy of the specific fuel.
    The turbine inlet temperature is a critical parameter, which affects the turbine life .Using the fuel controller the engine acceleration was actively limited to prevent over temperature. But also the deceleration of the engine was limited to prevent flame out. As you mentioned, there was no reliable way to measure this most critical parameter directly.
    Outstanding professional presentation.

      I'd actually approach this differently now even on the highest performance engines.
      Direct measurement is best because it avoids potentially unexpected events that the models haven't anticipated.
      Laser/fiber pyrometry can measure these temperatures directly at a sufficient standoff distance. You can also obtain spectral information about the mixture and emissions.

      I agree, fast response direct sensors are better for control stability than the delay caused by digital computation lag.
      What is important is the combustion gas spacially averaged temperature prior to the turbine inlet guide vanes. The temperature is lower of the gas flowing over the radially stressed turbine blades.

    May I suggest you add a pitot tube to your turbine stage outflow to measure the actual energy you have available for making thrust/SHP , its an invaluable tool for tuning/optimising the engine, it needs to supply a 1Bar gauge , generally a DIY engine will produce ~0.5 Bar of P4t , though when maximised it can be closer to 0.8 Bar

    Just basing this on my rudimentary knowledge of turbine engines, but would it be useful to seal the oil reservoir and tap in the boost pressure to the tank? In theory, that would make the pressure equal on both sides of the oil seal, preventing oil escaping, and preventing air getting into the bearings and starving them of oil. Then you could simply lubricate/cool the bearings with a circulation pump.

    With the oil filter you can easily adapt it to use regular automotive spin on filters, as you just buy a hydraulic oil filter adaptor block, and then, depending on the thread and seal diameter it has, you put in a regular automotive filter spin on unit there to filter the oil. Cheap, and works well, plus the larger volume filter helps with extra heat dissipation, and also you might not get enough heat into the oil to need the extra oil cooler.
    Also strip the boost gauge, and resolder or replace the LED backlight LED's that are flickering. For water cooling you can also use motorbike radiators, or even PC cooling units, as the flow rates are not extreme, and they will work, along with the pumps. I used commercial refrigeration condenser units before for water cooling, bonus is they normally come with a fan mounted, though typically mains voltage, but 12V fans also are available that will work there, or just use 4 regular 12V 100mm fans in a frame to replace it. Pipes inside the condenser are grooved, for better heat transfer, which makes a big difference.

      This might serve only as an idiot proof feature, the water still in the housing can help to absorb a bit of the excess heat and prevent a bit of oil cooking. If installed properly the thermal siphoning can also maintain a bit of circulation even without a pump (but I'm guessing here).
      The low oil capacity of these engine might have something to do in that decision too.
      Since my engines contain very little oil for turbocharged engines (around 3.5l for the 1800cc or 2000cc versions, some smaller naturally aspirated engines contain a lot more), everything that can lower the stress on the oil is good to take.

    I'm rather curious. How would someone make an engine for shaft power using turbochargers? From what I know, the turbines are connected to shafts directly, which then have geared reduction outputs. These turbochargers seem like something you don't want to mess with, so how do you get shaft power without machining your own turbine? The same goes for multi-stage engines. Are the turbos plumbed in series? I can't imagine such an engine being used for anything other than thrust output.

      A current application of a stave turbo system is dragracing diesels. The are using 2 to 3 turbos in series to get to 120psi manifold pressure. Caterpillar and Volvo both have used staged turbo system in heavy diesel engines.
      I think it was Siemens systems has an indirect turbine power system. You have the main jet engine. Then just outside the exhaust nozzle you have what looks like another jet engine. They are using the exhaust gasses as a coupling fluid between the exhaust of the jet engine and the generator.

    • @TechIngredients

      First establish that those pressures are not associated with a flow restrictor to limit flow to the turbo. The real pressure the turbo sees is downstream from any restrictor. Make sure THAT pressure is at least few psi higher than the highest boost pressure ever reached.

      @@TechIngredients first the concept, you take a wheel and place permanent magnets around the outside diameter attached to wheel evenly spaced all with the same poll facing out. We can call these magnets ODM "outside diameter magnets".
      Then place magnets around the perimeter of the wheel evenly spaced and a distance determined by magnet strength. We will call them OPM (outside perimeter magnets).
      The OPMs are encased in a mu-metal "shield" to decrease the magnetic fields reach with an opening facing the wheel and a sliding door that covers that opening.
      Now you use timing gears on the wheel and on the OPM to time the doors opening dependant on the wheels motion, when the ODMs are in line with the OPMs to be pushed the OPMs door opens causing the wheel to be pushed "forward".
      The ODMs "strength" needs to be greater than the OPMs strength to overcome any resistance encountered when the shield door slides open and closed.
      Edit: the spacing between the ODM and OPM need to be such that the ODM magnetic fields do not interact with the shielding of OPM.
      This is the simplest and shortest way for me to explain this idea, i hope to get some feedback from you regardless if you want to cover this in a video.. Thank you for your time.

I realise that "perpetual motion" is cconsidered a sort of unicorn in science but I'm confident my design addresses most issues and isnt energy from nothing.

    • @TechIngredients
      @TechIngredients  2 роки тому +1

      The problem with your design is the shield. It doesn't block the magnetic fields inside and outside, it guides them. The force these magnets will exert against the shield is substantial and moving the shield will require at least as much energy as the "rotor" could generate.

    • @three6nine992
      @three6nine992 2 роки тому

      @@TechIngredientsif I cant satisfy your criticism of my design, we can just say I assumed it was a can opener and I will delete my comments.
      The "shields" whole point is to redirect the magnetic field, to shorten the distance it would normally reach. The magnet in the shield would be a weaker magnet than the one on the wheel, this is to provide more "push" than the drag on the door.
      The magnets on the perimeter are stationary and only the "shield" door moves and only far enough to allow the magnetic field to extend far enough to "push" the ODMs field on the wheel..
      Consider this, two magnets with like poles facing each other one is an N64 the other is a N35. N64 for wheel N35 for perimeter with the magnets being stronger on the wheel than the ones on perimeter, you will get a push stronger than the resistance of the door moving. The "push" will be equal to the N64 strength while the door drag will be equal to the N35 strength. On my design the OPMs would be far enough away so to prevent the ODMsField from interacting with OPMs shielding and so the magnetic fields of the two only interact when the OPM door is open.
      Edit: you can consider the "shield" door as almost a shutter on a camera, it only opens so far and for so long, dependant on how you time it.
      With each magnet timed properly, there will be a constant push exerted on the wheel. The numbers I use are arbitrary, only for conceptual explanations..

    Why add the complexity of the water cooling when you have the oil cooling? It's not in a car, so when you shut down your system you can leave the oil cooling running to let it cool down.

    • @TechIngredients
      @TechIngredients  2 роки тому

      As I explained in the video, that could be done and when using the turbocharger in a jet engine we do that. But, many automobiles already have a system in place that continues the water cooling operation after the engine is shut down and piggybacking the turbo onto this system is easy.

      Yes and no.
      The amount of heat it will absorb is relatively small, but pre heating the fuel will help with combustion.
      However, because the heat is not actually removed from the cycle, but fed back into the combustion chamber, no net cooling will result.

  • @Pystro
    @Pystro 2 роки тому

    Instead of the water cooling, couldn't you cool the engine with the fuel? I.e. from the fuel reservoir and the fuel pump, run it through the water cooling ports of the turbocharger. And then the hot fuel is distributed by the manifold: You can inject the pre-heated fuel into the engine (the lower viscosity will help the nozzles disperse it, and the higher temperature will help the hot combustion chamber to evaporate it). And whatever pre-heated fuel you don't use you can run through the radiator before returning it into the fuel tank.
    The only time when you would NOT want to do that is when the turbocharger exceeds the evaporation temperature of the fuel. (Because then you'd get a mixture of liquid and gas coming through your fuel lines.)

    • @TechIngredients
      @TechIngredients  2 роки тому

      Your theory is good.
      Safety might require some additional steps because you have a volatile liquid very close to the high temperature of the turbine housing. All metal, high temperature flow lines and an automatic fuel purge system to prevent trapped fuel from vaporizing and igniting due to contact with the very high temperature metal would be a minimum.
