  • Some of the strangest types of rocket nozzles(Toroidal Aerospike, Linear Aerospike, Expansion Deflection Nozzle, and Bell Nozzle) and how I designed, and tried to optimize them. Each nozzle is 3D printed in either PLA or PETG and powered by a 2 liter bottle whoosh rocket.
    The Rockets produce a lot of heat and pressure, only adults who are willing to accept responsibility for their own safety should experiment with things like these whoosh rockets.

    As an undergraduate in chemical engineering, I can confirm that gamma's are magic numbers you get by sacrificing a TI-84 calculator under the light of a full moon at the point where three rivers meet.

    this is all very cool! One thing I would love to see as a next step is 1, upscaled rocket setup (longer burn time, as well as taking into account the heat dissipation with different designs), as well as a nice table to show the results with the different nozzles

    • @anonymous-rb2sr
      @anonymous-rb2sr 3 роки тому +2

      A reason I say that it would be intresting to look at heat, is because in the video of the tests, we can see the triangular and pyramidal aerospikes melt
      For example, the reason the tip of the spike is troncated to begin with, is because the tip is almost impossible to keep cool, and cutting it off is a way to simplify cooling without losing too much efficiency

    We used to spray deodorant into a 2l bottle and do this (no nozzles though), and it would shot across the floor if you got the mix just right.
    If you put too much in, it just burnss with a yellow flame at the top.
    Anyway, my friend blew into a bottle with a yellow flame burning at the top one time. As he blew into the bottle, he changed the mixture, suddenly, a blue flame shot out of the bottle and took the skin off his lips. Looked pretty painful.

    Some ideas to consider trying:
    1. Connect the nozzle inside of the soda bottle with a short length of tube to see if you can increase the nozzle velocity. You could try changing the length of the tube to see if there is any performance boost correlated to the tube length. Perhaps the the exhaust flow could be closed to laminar your get better performance
    2. Add a second or three spark gaps inside of the soda bottle at different locations. This should increase the burn rate and may improve or reduce performance
    3. Try a nozzle with multiple orifices in a pattern which creates a synthetic nozzle. Hole sizes could vary such the the outer holes are smaller than inner holes. Also try a hole than isn't round, such that it jagged edges or a hole with half round arcs.
    4: Same a three but instead of the hole been flat, make it in a conical shape. Like if you used a exacto knife and cut a hole into a set of wedges but bent the wedges in or out. Creating complex exhaust flow. instead of triangle wedges try round edges as if each wedge was rounded instead of coming to a point.
