| thanks,Rolf you have interesting things! |
Here's something that could be fun. It looks like a model for a rocket-powered railcar- and that's about all we know.
Google-translate thinks the language is Polish but doesn't seem to be able to make anything out of it. Any ideas?
The V4-10 model mentioned is a model of a valve pulsed jet engine. Let us add that its designers intended it to be a fully functional jet engine. Automotive gasoline is expected to be used as fuel. This engine was equipped with a chassis with wheels and a track on which a force gauge was mounted. Yes. This engine was supposed to have measurable thrust.
Of course, an outsider may ask "what's so strange about it"? After all, engines of this type and size really have a lot of thrust and were, and even still are, used in aircraft modeling. Instead of an answer, we will only remind you that this is a teaching aid - created for use at school, to demonstrate the operation of a jet engine to 7th grade (?) students - i.e. approximately 14-year-olds.
Btw, it’s for sale.
