Discussion Overview

The discussion revolves around the design of an air-powered axial engine, focusing on efficiency in energy conversion, low start-up torque, and high RPM output. Participants explore various design options and seek advice on the most effective approach.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant proposes an axial engine design with a focus on efficiency, mentioning several design options including a Swash Plate, Trebert, Wobble Plate, Barrel Cam, and Radial Engine.
  • Another participant inquires about the desired RPM, indicating that performance metrics are a key consideration in the discussion.
  • A third participant expresses interest in the design ideas presented, suggesting they find them innovative and worth discussing further.
  • The original poster specifies a target RPM of around 2000-3000, which may influence the evaluation of the proposed designs.

Areas of Agreement / Disagreement

The discussion does not appear to have reached a consensus on the best design option, and multiple competing views remain regarding the efficiency and effectiveness of the various proposed mechanisms.

Contextual Notes

Participants have not yet provided detailed analyses of the efficiency or performance characteristics of the proposed designs, and there may be missing assumptions regarding the operational parameters of each engine type.

Hi.

I need some wisdom! Here is my problem. I want to make an air powered engine. This isn't a problem, I have plans for this. However, I want to put my own twist on the engine. I want it to be a axial engine, so the axle is in the same plane as the cylinders.

The importance factor is efficiency, I want this mechanism to convert the energy as efficiently as possible, translating to low start-up torque and high RPM output.

There seems to be a few ways to do this, so if I put down some of my options, can you advise me on the best route.

Option 1. Swatch Plate

Option 2. Trebert

Option 3. Wobble Plate

Option 4. Barrel Cam

Option 5. Radial Engine (I know, the cylinders arnt in the same plane as axle)

Option 6. None of the above!

Id be really interested to hear what your thoughts are on this, and input would be hugely appreciated.

how many rpm do you want to get?
 
Pretty interesting and clever design ideas you've found.
 
Hi! Thank you, it took me a while to find them. I am looking to get around 2000-3000rpm
