I'm very glad to see this mentions for my inventions at this web site.

I stumbled across this guy's YouTube Channel...

Anyone seen his work before or know who he is? Seems like some interesting creations and a good bit of professional level machining involved (at a university I'm assuming?)
Thank you for founding and mentioning me Mr.mobile chernobyl !
I have been wanted to discuss about pneumatic cannons at this web site for a long time. So today, I introduce you the situation of development of pneumatic cannon in Japan.
In Japan, although the number is small, there are people who make pneumatic cannons. But there are some difference compared with the common pneumatic cannons. Because gun-like equipments which accelerate projectiles are illegal in Japan, the objective of our pneumatic cannon is to generate intense impact and shock wave, and we call these equipments "Exhaust Cannon" as a equipment that fire off the compressed air.
As a result, many unique working principles of pneumatic cannon have been developed in Japan. And I have been tried to invent new working principles which improve the cannons. For example, I succeeded to add semi and full-automatic system with no electric devices. And I have invented several new principles which make the nozzle opening time shorter for the purpose of making intense shock wave.
Now, I introduce my 11th pneumatic cannon,"Exhaust Cannon Mk.11." I have been fabricated many exhaust cannons, and this 11th one is the my first semi-automatic cannon. And it has some contraptions to realize intense shock wave.
Exhaust Cannon Mk.11 with wearable air chamber.(The chamber is shouldered and it is behind me.)
Exhaust Cannon Mk.11
This is Nozzle. I fixed a metal mesh sheet on the nozzle in order to make it unable to load anything.
I fabricated the wearable air chamber system for Mk.11. As you can see, the air chamber is made from fire extinguisher. We can change the air pressure by controlling the air regulator valve.
we can carry wearable air chamber system with a special case.
One of the characteristic-feature of this cannon is the semi-automatic mechanism with no electric valve. As the guns don't use electricity for high robustness, I prefer a pneumatic system with no electric devices when I design the Exhaust Cannon.
Maybe, you in this forum can easily understand the firing principle of this cannon from only this photo. By pushing the valve which attached to the cannon, the piston unit at the center of the chamber starts to thrust back, and the nozzle is opened in the end. This system is just a single-action pneumatic cannon.
To realize the semi-automatic reloading, I added a special pneumatic cylinder. The right side system is the pneumatic reloading system. It has a role to push the piston unit back to the chamber.
So, please check the action.
This movie shows the action when the pneumatic reloading system was detached. You can see the Mk.11 generate huge sound and it is working on single-action.
And this is the action of pneumatic reloading system. Piston unit is pushed back rapidly.
And these are the latest action of Exhaust Mk.11.
We can enjoy not only the intense shock wave, and also the intense recoil shock.
And now, I'm Planning to translate my website or YouTube channel in to English. So, when the translation was finished, I will make the announce here.
If you have any questions, please ask me.
