Plans for Intermeshing helicopter

[karlbamforth]

I never really recommend anything from Vortech but this is quite an interesting helicopter I have not seen before.

Very good looking. Does she come with the plans?

[Sita]

This helicopter was designed and built by Belgian,Clybouw Willy but never flown!!
I had the plans a few years ago to have a look at them and it surely is a nice set of construction drawings.
Mr. Clybouw was a draftsman by proffesion,hence the nice drawings.
I visited Mr. Clybouw some years ago and he still had (the partially) disassembled helicopter in his garage.
He assured me that the craft never has flown due to all kind of problems he was unable to sort,mainly due to lack of financial support.

Nice to have those plans as a curiosity but not to built a working helicopter from.

Here is another European Intermeshing helicopter from the past.

Hi Cita;
Do you know what kind of gearboxe does she had?
Do you have the plans yet?
Thanks.

Hello André,

no I don't have the plans anymore as I just had them for study years ago.
Few parts of the CW intermesshing helicopter came from cars so I only can assume that the gearbox(es) came from a car to.
The best part of those plans where the drawings to build the aluminum rotorblades.
This was a really interesting approach with the spar being made from a bended sheet of aluminum.

Sorry to be of no more help to you André.

It's OK Gilbert;
Thanks.

Hello people,

last night I received a phone call from Mr. Clybouw,the designer of the CW-105 intermesshing helicopter and he gave some additional info.

First of all, he's wondering how Vortech got his plans for the CW-105 !!!
He never sold the rights to Vortech or gave them permission to sell the plans.

In 1971 a Northern Ireland company:The Ulster Light Aircraft Company took contact with Mr. Clybouw and an agreement was made that the Irish company would build a prototype (s).
An USA based firm,Phillips Helicopter Sales Company-New Berlin,Wisconsin,would participate.
A certain Mr.John Stewart of the Irish company emigrated to British Columbia-Canada and he too would participate in the development.

Sadly,shortly after all this Mr. Phillips died in a car accident which seemed to ended the project.


Being interested in homebuilt rotorcraft for over 30 years I know the "reputation" of Vortech-Helicraft,or whatever name they reside under now and the question is:has anyone got any idea what can be done to give the designer/maker of the CW-105 plans the credit he deserves,part of the money Vortech is making with the sale of these plans ?

I guess "company's" like Vortech are so long on the market and have so much "experience" in these practices that little can be done but one never knows.

On behalf of Mr. Clybouw,

Thanks,
Cita

On behalf of Mr. Clybouw,

Thanks,
Cita when I was designing and building the TH-135 Dusty2 helicopter Mike driggers did a web site for me, the next thing I know Vortech was trying to sell my plans with out permission,I made a call to them and threatened to sue them and they removed the ad.

I hate to say it, but I am building a falcon gyro and if I can avoid it I won't be dealing much with Vortech. I plan to contact designer Neal Carnes directly for my parts.

If I encountered a guy named Animal who describes himself as a sleazy old biker ...... I wouldnt be steal'n no plans from him I''ll tell ya....!!!!

Hey Animal ,thanks for the reminder about your Dusty 2 helicopter. I found it quite interesting. Some time ago you had an article on the machine , was it on this forum ? Do you know the link ? I would like to read it again.

Many thanks

From the Vortech website:

The fascinating CW-105F was designed, built and first flown in Europe...

The designer says it's never flown, in Europe or otherwise.

Any bets on how thorough the "build manual" is?

[Sita]

have no clue on the build manual but I know the plans where proffesionaly with high detail.

If you offer for sale plans of your own design, if you offer Owner or Builder's Manuals which you created, get a copy right on each and every one of them. Bill Gates did that, essentially stealing other's creativity which at the time did not have a copyright to protect the actual owner/inventor.

Use the copyright laws to protect your plans, Builder's Manuals and other "paperwork" related to YOUR invention - use'em or loose'em.

tycGreat advice here guys!!!

The sad thing is that some people think that they can sell someones work just because the can make a copy of them in a xerox machine but the thing is the designer is the owner of it, but ofcourse you can make your own design that looks limilar but ju cant just make a copy!

Some people dont, think about the work behind it, and that is for one simple reason -They wave never created anything by them selvs...

I appreciate the link to the CW-105F TWIN-ROTOR HELICOPTER , I remember it from my early days of helicopter interest.

It sure looked good , I liked the intermeshing rotors and clean design. If it flew as good as it looked , I would probably have had one years ago. So would most of us.

History has shown us a very few examples of designers who actually got their helicopters to fly. Even fewer flew more than once. Even fewer flew successfully. A couple even achieved certification.

If we cut all the fingers off one hand (just kidding) and some fingers of the remaining hand , and counted what was left , it would probably equal the total of all the remaining helicopter brands that are flying today.

This helicopter business is a difficult industry. Yet we were all captured by it because of folks like Mr. Clybouw and his design , his helicopter picture is shown below.

What I find most interesting is that in modern day , and on this forum , there are more great looking designs with good helicopter engineering , being built in neighborhood garages than the early pioneers could ever have dreamed about. They would approve.

If only we could raise them from the dead , and teach them to use a computer . I am sure they would be on this forum.

Thanks again Karl.
