XENON photos

[Xenon-designer]

Here is some photos taken in Africa this month, where i was able to demonstrate the Xenon...high altitude take-off (5/6000 ft) high temperatures, and a bit overloaded (oups) but it really went better than expected !
More photos to come soon !

It took us 5 years to develop the Xenon, as our approach was quite new, and we to the beginning wanted to have full calculations and analysys on all construction protocoles...and ALL parts. I want to belive that all other manufacturers do the same. As a new member here, i am browsing through many interesting debats and subjects, and i see al lot of misunderstandings on general aerodynamics and mechanics.
The Xenon is a piece of art development, we have put all the reasonnable features of designs to make a true stable and forgiving machine. The gyro world must get more professional to have a happy future.
To all, excuse my mistakes in english, it is not my native language.
Some photos here of our analysys.

Raphael,

great post, very informative and reasuring.

I can only confirm, after the test flight, that the machine
flies really smooth, almost no stick shake,
very well yaw and pitch stabilized.

We were flying (of course) with door on, at different speeds.

Congratulations for a great design.

Congratulations Raphael. A wonderful project and yes I believe the gyro world must become more professional. Well done.

Aussie Paul. :)

Raphaël, thanks for your posts. I would be very glad to see your study on the blades and rotor (aerodynamics and strutural). :)

[karlbamforth]

Thank you very much for your post, you seem to be very open about your design. It is not often that a designer is willing (or maybe unable) to post this kind of information.
I had some difficulty accessing your website (probably my computer) so please can you tell me, is your gyro CLT ? is it Yaw stable ? which seems to be a problem with cabin type gyro's.

I realise it takes valuable time but please keep up the informative posts as I am sure most of us find them very interesting.

[Rehan K.Janjua]

Hello Rapheal.

Congrats. Thats a lovelt looking Gyro.

Thank you for sharing and keep up the excellant work.

Let us all have your website so we can see and enjoy also would like to know the price of it too.

Good luck.

Hello to all !
Here in POland it is now 19h30, i see that i will start to get accepted here.
I'll try to answer all here.
Thanks for the greetings, it gives some warm in the heart, it is the best gift i can get from the work.
The Xenon is not anymore a project, our production started a year ago, 16 machines built today, 3 more on the order book. We are now truly starting the real job of promotion.
Thanks to Paul to trust me on our demo flight, i am always happy when i can make another pilot happy !
About analysys, we don't have much to hide LOL we were really happy to be able to do thoses analysys, like most of us, we're getting older, and the more i fly the more i want to fly in safe machines...We also did that to target to get Comercial certified one day...so all the paper and studies is now done.
Our main analysys were on the main structural parts, rotor head, mast, tail group, we even know our life time of components. We've been through vibration analysys too.
PLease forgive us, if i will not give all details, we have to keep some of our design secrets.
Why the Xenon is soo stable in ALL axis ?
First i designed the cabin with the shape of a water drop... the engine cover is not innocent at all.
Second, the tail is very very specific, cut it ! and it won't do the job...all matters of momentums.
I was sincerly inspired by seaplanes...i was thinking how do they manage to keep stable on the water with all engines effects ??? check on big seaplanes...I dod not invent anything, just applied the right solutions.
Also about trust line on the Xenon, this was studied carefully and cost me 3 prototypes. It is absolutely going through the GENERAL CG, considering the drag of our rotor. In flight you can play as fast and hard with the throttle you will virtually not notice any change in attitude.
About yaw, a box tail is tremendously effective...the Xenon is perfect respond what ever engine on or off...and what ever the speed. I fly feet on the floor.
I checked our website now, all is fine. Try again.
About rotor analysys, i have all, but as i am not the manufacturer of it, i cannot spread information without autorisation. But all would be surprised how serious those aluminium rotors are.
Good evening to all.

Raphael,

I started also one more thread about the Aircopter rotor blades:

http://www.rotaryforum.com/forum/showthread.php?t=10169

Could you comment on this, I am not sure if I understood you correctly:

- do the blades have steel inserts ?
- what about the differences in temperature reaction?
(see Chuck B. comment)

Paul

[quadrirotor]

I would be very glad to have the life expectancy of the blades, and the first and second mode frequencies of vibration of the rotor...(no secrets there!)
I think that the directions of forces on the 2X6 holes, in the upper part of the mast, in your F.E.M. analysis are wrong! am i mising anything??? As the thrust force (lift of the rotor) is not centered...

[Xenon-designer]

About the mast / plates, you are right, just because i did not put here all drawings...we tested of course in the right direction. I see that you are more acurate that most people. Congratulations !
Again, about the rotor, can't give anything without permission.
Life of blades through computer analysys in extreme conditions passed the 10 000 hours. Second, vibration from rotors are also due to non accordance to airframe own vibration frequency...this is were all the mastering of a professional designer comes...and i'll keep my secrets, so my customers can enjoy a truly smooth machine.
That was a bit rude i know.
To conclude i'll say, a rotor i kind of a living thing, needs to move a bit, not too much as well. And a good airframe can make a bad wedding with even a good rotor if there frequencies are not matching. To help that kind of problem, let's that some dampening devices can be necessary.

It's a nice looking machine, There is a guy at an airfield near me in Normandy in France who I saw putting one together during summer do you know if it's flying yet?

What make of right angle drive are you using for the pre rotator?

Mike G

Mike G

[Xenon-designer]

Hi Mike,

Yes the guy (Martial) has completed his machine and now logded many hours, and seem to be very happy.
We are using high quality spiro-conical drive. For high speeds and corresponding torque. You are welcomed to order spare parts to us.
Raphael

[Mike G]

Raphael
Do you have his phone number?

Mike G

[Mike G]

Raphael
You say that it is a spiral helical drive, do you mean spiral bevel gear? What is the kW rating, gear ratio and maximum input and output speeds of your gearbox ?

As you can see I have a Magni but I would like to change from the flexible drive to one similar to yours.

I might even be interested in a complete pre rotator from since I have a Rotax 914 like your Xenon there shouldn't be a lot of modifications.

Mike G

[Xenon-designer]

Hi Mike,

I guess it is what you say. It is NOT standard gears. Gear ratio is 1/1 max input is 15 hp and 2mkg as output. It is internal lubricated.
I am afraid in your case it is not suitable, as the Magni ratio is different than ours...our pulleys wont fit. Give me your number teeth big ring and pignon. I'll see what we could do.

[Mike G]

Raphael

The ring and pinion ratio is 8 to 1, I can't remember the exact number of teeth.

Is there any chance of getting a telephone number of the Normandy owner, I'd like to go and fly with him.

Is your agent in Normandy a guy called Barbier?

Mike G

[Xenon-designer]

About your ratio, it wont do...unfortunately.
No, mr Barbier is not anymore our distributor.
Call Martial : 06 75 02 48 14
Were are you located ?
Tell me more about you

[Mike G]

Raphael

Did you get my e:mail?
What's the situation with Barbier, I've heard good and bad things about him, but that's the case for everybody.

[rotormaster]

Has the Xenon Shop closed down in Poland ?? They out off Bussines or just move out of Poland ?? Anyone knows more about ??

Thats Right, Raphael Celier leaves Celier Aviation in poland :wave:

the new business from Athur

http://www.autogyro.eu/index.php/pl/

[PTKay]

The page of Artur is there since few months.
Do you have any conformed information that you could share with us?

A.f.a.I.k. the negotiations are not over.

[Resasi]

As I think there is always interest in the Xenon range from a lot of us on the Forum I am sure many are wondering what is happening.

I have observed that a number of former agents and some owners seem to have had differences of opinions with Raphael.

It seems to have been a good machine, and as far as I know still the only production three seater available?
