Re: Valveless PJ powered Hovercraft?

hmm, kilograms, newtons, hmm, always mix up. :(

So after re-evaluating I have to admit that the pressure will be only 0.01 bar (1000 Pa) and not 0.1 bar :oops: :oops:

Found the methods of how to calculate the needed air displacement but I didn't study them yet.
Will be back.

Re: Valveless PJ powered Hovercraft?

Hello M., Sometimes "old-fashioned" is best . Today we make noodles the same way we did 4000 years ago, when the Chinese first invented them. I don't hear anyone complaining about "ancient" spaghetti! :wink: I went to the local chinese restaurant and asked for last months noodles and today's noodles...

Re: Valveless PJ powered Hovercraft?

M. answered me: PS: The lift cushion is best supplied via a ducted fan; I can help you size one, but open a separate thread if you want to discuss or build the hovercraft project. mm, ducted fan, kinda old-fashioned :( seems more fun to me to use a PJ for that purpose. Compact and lightweigt!(and ba...

Valveless PJ powered Hovercraft?

I wrote this post in another topic where I was asked to open a new topic: Man, I'm getting inspired by these "alternative" applications of the Thunderchine and because of that some turbulence of ideas and questions is taking place in my head.

Re: Spare thrust for airliners in case of emergency

Luc, I've read the topic about the new pulse-ram and your company. Maybe an idea for business expanding? Wouldn't be to dificult with Cesna's etc. Most difficult problem to solve is probably certification, but I can imagine that you are already familiar with that. But anyway, who has the numbers for...

Spare thrust for airliners in case of emergency

Probably you've all seen yesterday's plane crash in Holland. Some say it was due to total engine failure. Here is where my fantasies start, would't it be great if planes had back-up pulse- or pressure jet's for in case of engine failure? With just enough thrust to keep the plane in the air or in a s...

Pressure Jet's and Hearing Problems

Eugene Gluhareff probably had something in his DNA that drove him to live with noisy stuff! Why? Gluhareff is probably the American way of spelling the East-European or Russian name "Gluharev". :roll: The -ev extension means something like the -s in Peters. Exactly, the -ev and -s means "his". This ...

Re: Valveless front end for a Dynajet

Mike,
I was mistaken, the Dynajet isn't in the freeplans. Were you thinking about the Dynajet in the attachment?
