Discussion Overview

The discussion revolves around the construction and performance of a simple pulsejet engine that can be built for under Rs.110. Participants share their experiences, design details, and performance observations related to this type of engine, which is characterized by its ease of starting and good throttling range.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant claims that the pulsejet is easy to start, requiring only a single attempt, and invites others to engage in building the design.
  • Another participant shares a nostalgic experience of attempting to build a reed pulsejet as a child and expresses interest in obtaining dimensions and plans for the current design.
  • A participant provides specific design details, noting that the pulsejet is valveless and includes dimensions for standard pipes, emphasizing the availability of materials.
  • One participant reports that the pulsejet produces significant thrust, mentioning an attempt to demonstrate this force with cloth and cardboard, although the latter resulted in damage to the engine.

Areas of Agreement / Disagreement

Participants express enthusiasm for the pulsejet design and share personal experiences, but there is no consensus on specific performance metrics or detailed construction plans. The discussion includes both shared excitement and individual inquiries, indicating a mix of agreement on the concept and varying levels of detail in execution.

Contextual Notes

Some participants mention specific dimensions and design features, but there may be limitations in the provided details, such as missing assumptions about materials or construction techniques. The discussion does not resolve potential challenges in building or operating the pulsejet.

Who May Find This Useful

Individuals interested in DIY engineering projects, pulsejet technology, or those looking for low-cost engine designs may find this discussion beneficial.

This is the simplest pulsejet you could make and costs only Rs.110 and has got a good throttling range,which you could see in the video..No need to strain much to start this engine it starts in a single attempt..If anyone need to make this design please reply here..Thanks for watching see you all in the next pulsejet video..

This is great! I remember as a kid trying to build a reed pulsejet... Got as far as cutting the reeds by coating spring steel w/ paint and scribing lines / reverse electrolysis machining the metal.

I'd be interested in seeing dimensions / plans - perhaps I can build one for fun one day!

Thanks,

George

this is valveless so no problem for us,no need to make valves:cool:..here is the design..All dimensions are in cm..Those are standard pipes so readily available in markets..:smile:

note: place the inlet fuel pipe at a depth of 4.3cm into the intake pipe..The fuel pipe dia is 3mm..

this has really got good thrust,tried to show an cloth near it but i was not able to do it,so much of force from the exhaust pipe..one day i will hook it up to a scale and find out the real thrust..

note: at the end when i tried to show a cardboard the engine got few holes in the welded parts..
