Model Steam Turbines (Classic Reprint): How to Design and Build Them; A Practical Handbook for Model-MakersExcerpt from Model Steam Turbines Steam turbines may be divided into two classes: the impulse or action type, in which a jet of steam or ? uid at high velocity impinges on a number Of vanes or paddles fixed around the rim Of a wheel free to rotate, and the reaction type, more generally known as Hero's Engine or Barker's mill. Both these types are pretty familiar to us from our Childhood's days, in the windows of the toyshop, and no doubt in many cases

Excerpt from Model Steam Turbines

Steam turbines may be divided into two classes: the impulse or action type, in which a jet of steam or ?uid at high velocity impinges on a number Of vanes or paddles fixed around the rim Of a wheel free to rotate, and the reaction type, more generally known as Hero's Engine or Barker's mill. Both these types are pretty familiar to us from our Childhood's days, in the windows of the toyshop, and no doubt in many cases (the writer's also) formed our first steam model. They are illustrated in figs. 1 and 2, and frequently appear in patent specifications, though, of course, with considerable modification. In order that the principles on which these machines are designed and for which they depend on their action may be thoroughly understood, the following elementary mechanical considerations are necessary.

Dog loves this toy
Our Golden Retriever loves this toy, I would recommend it for that reason. But she did manage to chew off the smaller fins within the first couple of days. But considering she is pretty rough on her toys, I would still recommend it.

My dog loves his fish!
It's very strong and durable except for the patch on it my dog removed it in 10 minutes but the fish itself is holding up great!

Tall lost Tail
Simba went fishing for a good time, but it looks like the fish toy got hooked on destruction instead - gone in 20 minutes!

Nice toy, but maybe not so durable
This is our second one of these, which really speaks to how much my dog loves it… it’s cute and just the right size for my Vizsla. She absolutely loves playing with it… it’s chewable and has a nice squeaker, but I’m not so sure of its durability. Our first one lasted about a month, and this one just a couple of weeks. The stitching at the tip seems to give away first, then the find. Sadly, you gotta throw it away when you see the first signs of the stuffing.
