Discussion Overview

The discussion revolves around a proposed design for a powerful rotary internal combustion engine aimed at applications in UAVs, MAVs, robotics, and mini-generators. Participants explore the mechanical design, production methods, and potential advantages and disadvantages compared to existing engine types.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant describes their rotary engine design, highlighting its potential for high speed and power due to uniform rotation and small size.
  • They compare their engine to existing types such as Wankel, RCV, and traditional four-stroke and two-stroke engines, noting the advantages and shortcomings of each.
  • The design aims to address challenges in producing small mechanical parts, suggesting that their engine could be manufactured using forging or EDM etching methods to reduce costs and improve reliability.
  • Concerns are raised about the sealing and normal rotation of the rotor, with the participant acknowledging issues in the initial design that need to be addressed.
  • Several posts include links to videos, but their relevance to the discussion is unclear.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the effectiveness or feasibility of the proposed engine design, and there are no clear responses to the initial inquiry about understanding the design.

Contextual Notes

The discussion lacks detailed technical specifications and relies on the participant's descriptions, which may not fully convey the complexities of the design or its production methods.

Powerful rotary engine?

This is a powerful rotary internal combustion engine. When rotor round one time, engine work six times.My mechanical design aim was to create a power for UAV,MAV, robotics, mini-generators; engine size is very small, can be forged or EDM etching method of mass production. Because the rotor around its axis, uniform rotation, so it can reach a very high speed, high power.

Currently, power machinery, achieve practical machine are wankel engine, RCV engine, and there is a traditional four-stroke internal combustion engines, two-stroke internal combustion engine, and so on. They have their advantages, but also have their shortcomings. Especially the mechanical size less than 1 cm, the disadvantages of exposure of particularly, RCV engine, the traditional four-stroke internal combustion engine and two-stroke engine with considerable difficulty processing, especially tiny part of the process is more difficult, the production cost is very high, the work reliability was really bad. Wankel engine’s parts relatively few, small size relative high reliability, but cutting machining is difficult, difficult to implement low-cost lot size
Production.while my engine rotor and stator's face is an irregular surface, machining difficult too, but the face is smooth, in small size, available material in plastic processing technology for low-cost of production and the use of plastic processing methods are forging, EDM etching, forging will not only enable low-cost production quantities, but also can improve the mechanical parts of the structure, part of the strength and surface finish. Adopting EDM etching, can improve parts of sealing and wear resistance, the specific method is: etch out a lot of fine grooves on the moving parts which need sealing, forming the labyrinth, with labyrinth seals, improve sealing performance. and on the sliding contact surface, etching a lot small pits, lubricants, as far as possible remain in these areas, to improve the machinery lubrication performance.
study the 3D images that I upload on to forums, that structure, you should understand that was not possible work, because the rotor projecting too sharp, not only the room’s sealing cannot be guaranteed, and the normal rotation of the rotor cannot be guaranteed. There are a lot of problems you can see, after all, is a previous primary design! If you are interested in,Your views? email sky-hawk@126.com
