    I think those bottles will go up to about 100 psi. I don’t get the sense that you’re up there. If you want butter momentum transfer you might put a little bit of water upstream of your turbine. Make the air push the water, and when that water hits the turbine, it will spin the turbine. The tailboom is going to respond to gravity and give it a pitching moment. You might consider a static piece of that carbon tube sticking out the front to balance it. Winglets on the tips of the rotors do wonderful things for reducing loss. There are big wings where they will do a 10% reduction in drag. Some of the design constraints going into the commercially available propellers are speed of mass production.

    Maybe, you should put the air inlet conector right below the rotor, so the lift is balanced, it is definetly the main reason whythe copter is going forward every time...

    You need a check valve for the inlet nozzle. Then you don't have to manage the outward flow, and you retain a little more air for propulsion. Looks like you're 90% there, and you just have to work on that very difficult 10%

    Look up early helicopter designs. Very early models have two rotors rotating in opposite direction with an angle toward each other, (like a very shallow v) the steeper the angle the more stable is the helicopter. But it will have costs in efficiency. The reason is that if the machine tips to one side the rotor gains efficiency and the opposite loose it, pushing the machine back into a balanced position.

    The shock diamonds don't necessary mean that your flow is supersonic. It only means that the air outside is compressing the flow enough to make it compress on itself and then explode, creating the shock diamonds. You can have shock diamonds with water behind a ship, but I hope you agree that the water behind a ship isn't supersonic.

    Thrust efficiency from a propeller also depends on the pitch, not just the diameter. Pitch is usually given in inches, for model plane propellers - it's the distance the prop theoretically travels in one rotation, in a very idealised situation. As a rule of thumb, a propeller with a ptich of half its diameter (e.g. 8x4 or 6x3) gives the best static thrust. For a prop with more pitch (e.g. 8x6 or 6x5), you get a better top speed, but less static thrust. It's a lot like choosing a gear on a bike, or in a car, then driving in just that one gear.

    One thing to note is that you can create a helicopter setup like the CH-47. This was not the first heli with this setup, but it is one of the more successful ones. Why go to this setup. The first reason is that as opposed to having stacked coaxial rotors the dual rotors in this setup will allow you to increase your effective rotor disk area as well as canceling torque. Weight will go up, but you can also carry a larger volume of air. If the bottle size were increased to a 3L bottle, the volume will increase faster than the weight increase. I also have taken these bottles over 120psi over a few cycles and they have worked, so you may be able to increase the stored energy as well, though may need to change the fill method to accommodate the higher pressure. Just some thoughts. It was a really fantastic video to watch, and awesome to see the shock diamonds.

    It needs a tail rotor, a slightly larger/thicker air container probably, and a full body clamping mechanism to hold it down while it builds air pressure. Then it will gain more RPM without tilting forward; and when it flies off into the sky on release, the body wont spin around in circles. Also i would experiment with a different main rotor that has higher mass and slightly lower thrust so it can store more energy and bleed it off over a longer period. Also probably needs a stronger air valve to handle the pressure being loaded into the bottle

    Great example of the value of a project even when it fails to reach it's goal. The development of the turbine was fascinating. Not sure if you'd want to go down this route due to the increased potential for catastrophic failure, but wrapping Kevlar thread around the bottle may increase the pressure it's able to hold similar to how the diaphragm in your diaphragm engine was able to hold more pressure once enclosed. I remember from my SCUBA diving years seeing tanks that were wrapped with fiberglass or Kevlar being able to hold significantly more pressure than straight aluminum tanks. I think this technique is also used in paintball tanks. Wrapped with a cross pattern, the kevlar thread would prevent the bottle from stretching in it's weakest area - along the sides, and even enough thread to wrap with a 1cm/1cm cross pattern would probably add negligible weight.
