Default New Ultimate Jets/ Frankel project: large F-4D Skyray

Our factory, Enata Aerospace, is working on a new project.

It is a hyper scale 1/5 scale Douglas F-4D Skyray.

This airplane has been developed under contract from Mark Frankel, the World Skyray specialist and Douglas Historian.

Mark has developed, flown and sold to the market a 1/7 scale version of this plane in 1990. The kit is still sold as of now and is very famous. However, Mark wanted to go one step beyond his original project in terms off size and scale authenticity.

Welcome to the Ultimate Jets/ Enata Aerospace/ Frankel 1/5 scale Skyray!







The plane has been entirely CAD designed and 7 axis robot milled with our Kuka machines. Milling accuracy was to 1/15th of a millimeter. Then, the airplane sub-structure was drawn and sanded down to create the wrinkles effect.





The wrinkles are made subtle and only show when looking at a tangential angle or when touching the skin surface.

These are made according to the thousands of detail pictures that Mark has accumulated about the plane, including many ultra high resolution historical pictures of the Skyray production line, which proved to be unbelievably useful to us.





For example, the picture above enabled us to extract wing details showing the skin wrinkles and rivet patterns as well as access doors.





Now compare this to our plug in progress:



Notice that the wrinkles are very close to the original plane.



Here is a picture of the fin:





The plane prototype will be tested after the summer.

Looking great Oli. Glad to hear that you're working with Mark...no doubt that he is a leading expert on FORDs!

Perhaps an F-106 in the future?

This will be the ultimate Frankel Ford! Mark is outdoing himself with this project. Outstanding!

Fantastic progress Oli! So neat to see this coming to reality!

Mark wrote a wonderful book on the Skyray for anyone who may be interested:

Yes. Different extra work packages will be available to bring the plane to turnkey.

My guess is 140 to 180 N.

I am targetting 15 kgs dry for the full carbon fiber version.

We have not been contracted for an F-106 as of now. But who knows?

Nice size and can be transported on the gear. I like where the wing separates right at the small LE slat seam.

We did not reinvent the wheel. We re-used all the proven designs of Mark's 1/7 scale Skyray...
These planes still fly around after 20 years. I think that it is a testimony to the sound design...

Oli,

I couldn't be more pleased with the progress! I can't wait to get Ship #1 in the air, with the leading edge slats and functional pitch trimmer this "Ford" should land itself. The tooling was generated from Guido Ising's 3D CAD files who, in my view, is a genius of 3D design

The Frankel Skyray is moving really fast, now.
The small molds have been released, polished, painted and laminated. The skin is full carbon fiber ( our Cloudtech laminate ).




The wings molds are released and polished.






The fuselage is molded. Here is a picture of the last center section before gel-coating.



We are expecting the fuselage mold release in 2 days from now.

Here is a quick video of a freshly demolded wing.

The early parts are very impressive! I look forward to prototypical 70 degree takeoff climbs and stable nose high landing approaches. Do you plan having the #1 airframe on display at Jet Power?

Me too!
Yes, prototype #1 will be on display at Jet Power. Freshly out of the moulds...

Here are some pictures of the first prototype out of the molds that will be on display at Jet Power.

That is the CAD that was made for the F4D Skyray. Same as with the Cougar, the finetuning of the shape took weeks and brought me and my computer to the limits. The Skyray shape is quite demanding, especially the blending of the fuselage and wings.
