- So I made my next try at making an air pressure engine! The results have increased the efficiency of the engine by a literal order of magnitude... Wonder if it is possible to squeeze out another order of magnitude improvement with V3, mmh?
Hope you enjoyed the video! And I hope You have a great day!

Hey there! If you are looking for the STL files of the BMV2-V2 engine showcased, then you can find a link to the Printables page in the description of the video!
Hope You enjoyed the video!
Thats a beatiful video and channel I love it
Have recently found your channel, really enjoying your videos! Designing my own engine and your design has given me a bunch of inspiration!
damn, you have improved a lot since your earlier videos, i really like this video style! the engine is awesome and i think there is a lot of potential!!! cant wait for more videos!!!
How does this only have 800 views??
absolutely love the videos
cool as hell
you could probably skip the rubber membrane; rubber has a lot of hysteresis that eats your efficiency. these things often have some sort of slippery plastic piston seals? teflon, UHMW Polyethylene, or maybe nylon?

Make a boat with a compressed air reservoir and see how it goes 😊
A boat might indeed be the one :D
@@BirdbrainEngineer Let's make it happen captain 😉👍🏼
a train would be nice. we have seen cars and planes before but not a train
What software are you using for the exploded view animation?
Blender
imagine using liquid nitrogen as a source of air and then a 3 way valve to redirect the gas flow to the engine) another option is liquid butane, but it's inflammable, so... maybe the liquid that is on air cans is an option
The problem with using liquefied gases is that as they change from liquid to gaseous phase, they cool down... *a lot*. Not only does this mean lost energy for running the engine, it also means the engine gets cooled down, often down to cryogenic temperatures, which would destroy the diaphragm(s) of the engine.
@@BirdbrainEngineer probably a radiator is required in between to allow enough time to normalize the gas
@@Lucas_sGarage A heat exchanger to heat up the gas before it is used in the engine would work, but in most cases you'd be better off creating something akin to a steam engine then instead.
@@BirdbrainEngineer i was just thinking about weight/performance ratio
First :) also really awesome video also would be cool to see it on a bike
Thanks! ^v^
This engine design is very similar to Tom Stantons engine, although he did get the inspiration from old air hogs engines
It is brought up in the video, that it is certainly inspired by Tom Stanton's design, though there are some differences such as a different crankshaft design and the different diaphragm material, which allows it to work at very low pressures. (And of course - this engine is a V2)
@@BirdbrainEngineer none the less, a very big round of a applause for creating a new design
Printed props just really suck, especially compared to carbon ones. I set up a thrust test stand a while back and I found that the same pitch and diameter produced less than half of the thrust, when compared to cheap plastic props. Considering Tom used an even fancier prop, this could have a lot to do with the results.
Yep, it did occur to me, and for future, I have already ordered carbon fiber props of different sizes... Couldn't really that easily choose the prop pitch though, as they were meant for some large drones I guess.
Plane
Will have to dramatically increase the efficiency and lose weight before I could get a flying plane to work... but I may try that some day.
Your flywheel is pretty badly out of balance. If you're interested in air engines, you should look into the Lego Vacuum Engine community. Easier to design and make much more power.
I have personally seen my inline twin reach ~1600rpm and produce almost 35 watts (from a three phase motor to a rectifier and through a variable resistor)
The flywheel for the prototype was horrid, yes.
Problem with lego engines is that they are way less precise than 3d printed stuff and moreover... they are *massive* compared to 3d printed engines. The reason I do not want to make a vacuum engine for now, is because I want the engine to be capable of powering something as a self-contained unit (eg. a boat)... having a vacuum cleaner pipe constantly attached to the thing that is being powered just sorta feels like cheating and a bit of a copout :P
Великолепно...
