Ok, I see there is some confusion. Here is a link to the eclipse

I am not a proponent of the eclipse plane because it is backed by Bill
Gates himself. If it flies anything like microsoft windows, I don't
want to be in it. Also, the FAA has no business being involved in
prototype development. The only result I see in the program is a cluge.

I am offering to build a prototype incorporating a similar propulsion
system except with a single engine. The wing and fuselage design will
be of my own. It will be efficient and unsophisticated.

ummm....why did you title this thread, "jet powered personal glider" if you
truly meant an aircraft that would compete head-to-head with the Eclipse? Any
pilot would know the difference between a business jet and a glider. It's hard
to have confidence in your design team when you have such a loose understanding
of fundamental aviation concepts. You said, "I have an electrical engineer and
a mechanical engineer and I myself am a geometrical designer." Any aeronautical
engineers on your design team? Any *pilots* on your design team?

If the answer is, "no" to all those questions, why should prospective investors
have any confidence in your team's ability to design a plane that can beat the
Eclipse? Especially given that the Eclipse team has a five-year head start?
What is your plan for 14 CFR Part 23 qualification?

How does your design compare to the Cessna Mustang?

First of all, it will be a lightweight single engine plane. The concept
happens to be based on a 85lb jet engine with 750lb of thrust. If there
is catastrophic failure due to running out of fuel, etc., the plane
will be able to glide instead of deploying a parachute like the eclipse
does. I didn't intend to go "head-to-head" with a billion-dollar
project. I simply wanted to provide a worthy alternative for pilots who
don't need the size or expense of the eclipse. It won't promise to
"match" eclipse on any of the specifications. It's a new design
altogether. It isn't a "spin-off" of the eclipse. I only mentioned the
eclipse because that is the plane currently revolutionizing the entire
aerospace industry. I can introduce a plane that can revolutionize the
industry as well, possibly for a broader market. I'm not calling it a
business jet. It is a personal jet capable of gliding, as opposed to
parachuting.

Your other concerns are worthy of consideration. As this project is
hardly a day old, I think the details can be worked out eventually and
it is too soon to say: "oops , no pilot, no aeronautical engineer, no
billion dollars, oh well!!"

The difficulty is, I'm suspecting you have absolutely no idea what goes into
designing and building an aircraft. I doubt anyone in this newsgroup objects to
discussing new aircraft concepts and alternate ways of efficient flight. I'm
certainly not objecting to you posting about a new airplane concept.

The problem is that you are posting to this group on a hunt for *investors*,
claiming a prototype cost of $250,000, when you:

A. Aren't a pilot
B. Aren't an engineer
C. Have assembled a aircraft design team without an aeronautical engineer
D. Don't know what it takes to build, analyze, static test, or flight test an
aircraft.
E. Aren't familiar with the FAA rules for certifying aircraft.
F. Haven't done a shred of research on the field to know of the other small
jets being developed by companies that HAVE all the above experience. For
example:

http://www.aerocompinc.com/airplanes/CA-Jet/index.htm

Now, pretend I'm a potential investor. The above company, Aerocomp, has been
building small airplanes for ten years, including several turboprop models.
Explain to me why I should invest in your plane instead of theirs.

Finally, I didn't see any mention on the Eclipse web page of their aircraft
having a parachute for airframe recovery, as you claim. They are carrying a
spin-recovery chute during flight testing, a normal precaution. Their
performance page lists a stall speed of 67 knots, which means it will glide
quite nicely without a chute.

eclipse jet. "

I said prototype cost of 850, 000 and that is the target. The target
for the regular production is 250,000.

That aside, I appreciate your input very much. Thanks for the serious
effort you are putting into this discussion. I will keep everything in
consideration and will be better prepared in future presentations. I am
so fortunate to have people here willing to volunteer their time to
show me where I need to improve.

As far as investors go, I think I should not rely on this forum to find
them. However, as I mentioned, I will be better prepared now that I've
had some feedback.

I will definitely and absolutely defy all bureaucracy until after the
prototype is completed. To reiterate, I will not tolerate any
interference from any government or private agency or institution
during the prototype phase of this project.

I consider all of your previous objections to be advantages on my part.

You're not going to be able to fish design secrets or information
sources from me so give it up. I've had a great time and it's been
entertaining. I wasn't looking for a debate, but it's been fun.

In which case, I assume that you developing the aircraft outside of the US,
since, by law, you can't fly the airplane here unless the FAA grants you an
airworthiness certificate. Unless you're going for an
Experimental/Amateur-Built license, the FAA won't grant you such a certificate
until you prove to them that the airplane is adequately designed. And the
Exp/Am-Built only lets you build *one* airplane...if you want to go into
production, the FAA *seriously* gets involved.

So...how are you intending to keep then away?

True, but what you are designing will be operated by pilots. TV wasn't
developed by a blind person, nor were computers developed by people who couldn't
handle mathematics.

B. Aren't an engineer

B)I'm not bound to the overhead of having "a career on the line". I

Ever hear of a man named Burt Rutan? He's an engineer and aircraft designer,
and doesn't seem to be hindered by "having a career on the line" nor is he
limited by knowledge of the accepted design boundaries. His designs have
bordered on the fantastic, but he hasn't been hindered by any peer reviews.

And you know, *he* doesn't have any problems finding investors....

C. Have assembled a aircraft design team without an aeronautical
engineer

C)Same advatages as above.

The purpose of an engineering education is to be able to understand *why* things
won't work. Say someone came to you claiming that they had developed a
fantastic new aircraft generator. Say you glanced at the design and noted the
output wires were 26 gauge. Your past experience would tell you this was
totally inadequate...you wouldn't need to install the unit in an airplane to
find this out.

Due to his or her background knowledge, an aeronautical engineer will be able to
prevent the design from dead-end routes. There's little that hasn't been tried,
at some point, and part of an engineering education is to know *why* some things
wouldn't work. Yes, a sharp-edged airfoil is faster...but an aeronautical
engineer would know the drawbacks when it came to slow-speed handling.

D. Don't know what it takes to build, analyze, static test, or flight
test an aircraft.

D)I don't need to know everything. Every task will be deligated to the
most qualified. That's my accepted responsibility.

Certainly! But you've already rejected hiring the kind of person (e.g.,
aeronautical engineer) who would *know* how to do this stuff. And without a
general understand of the process, what do you use as a basic for estimating
costs and schedules?

E. Aren't familiar with the FAA rules for certifying aircraft.
E)I am determined to prove beyond a shadow of doubt that the FAA is a
hinderance to all intellectual activity or scientific discovery. They
will not be necessary for the prototype development and would only get
in the way.

I think most of us here agree with the sentiment, but the realities of law, as I
explained above, are different.

F. Haven't done a shred of research on the field to know of the other
small jets being developed by companies that HAVE all the above experience.

F)I wish not to be influenced by old ideas when my stated objective is
to develop "new" technology!

Start with a basic trade study of ambulatory and communicative skills between
specie and bovine excretatory products....

Then it will never leave the ground in any country that has a government.
Certainly not in the US or Europe.
