In 94 I got the idea of using a rotary to drive a ducted fan. Information
was scarce. It wasn't until 97 that I found a book for sale on the internet,
"Ducted Fan Design" by Marc de Piolenc. It is the equations in that book
my ductfan was designed to. There is an example in the book, where Marc
designs a ducted fan to improve the performance of the Jet Hawk. That was
the first I had heard of the Jet Hawk. So my knowledge of it is limited
to what I've read in that book.
I tried at one time to get plans, but never found anyone
that wanted to sell theirs. One of the people that replied did refer me
to Marc de Piolenc though. Since you're pretty well immersed in the ducted
fan world, have you seen any other aircraft similar to the Jet Hawk. In
other words, internal ducted fan designs that look like real jets? If high
rpm is good, then what would be better than a Renesis. On the other hand, there
might be some affordable real jet engines available now. I just haven't
looked.
Thanks,
Rusty
There is a really cool one, called Questar or something like that, mentioned
in Marc's book, but I don't have the book here to verify. Unfortunately I
think it is a dead project, I tried a year or so ago to follow up on it and
got nowhere. It was being developed in California. Tomorrow I can get the
book at the hangar and tell you more.
