Title: New Canard Design - Oshkosh 2016
Post by: Tom Mann on May 06, 2016, 09:14:18 AM
I was offered a spot on the team that is doing the Vacuum Infusion demo this year at Oshkosh. Talk about a learning opportunity!!!
 It will be a new canard design that should prove to be a screamer.

 All of the components will be fabricated onsite over the course of four days (Tues.-Fri.)
 This will be located in the big tent next to the Warbird Replica building.

 Itís not often that we get to see the birth of a new Canard design/kit.

Jabiru diesel for starters.
Later a jet version.

Talked with the lead on this project and things are proceeding on schedule.
 Here's a pic of them milling out the bottom half of the fuselage & strakes.

I mentioned a 'new canard on the block' some time ago. The aeroplane is called the e-Go and is factory built under the new Single Seat Deregulated(SSDR) category in the UK. It is  all carbon fibre and powered by a rotary (Wankel) engine. This first aircraft is revealed on 7th June to its owner - me. It is now in serial production, and I am now running the company. It turns like a fighter! Hope we can compare notes when the new canard design is revealed at Oshkosh. We are on www.e-goaeroplanes.com. We will look to launch in the US next year. Watch this space . Best of luck. Murray44

Exciting stuff Murray!  Look forward to the continued development.

Just got some additional information via Jeff:

Guys, this will be fully retractable and there will be two prototypes built.
One will be twin jet powered ( both engines residing in fuselage side by side much like the F-18 ) . The second will be piston powered, but not diesel( someday,maybe),with a Jabiru 3300 the likely choice.
 The FAA approved program Bob Carlton offers is not that intense and makes it pretty easy to acquire your turbine qualification.
 It will be a fast build kit offering and is single place. Build time of airframe will likely be around six weeks with diligent effort. We may consider offering staged purchasing of sub kits.

 It is exciting to finally get around to developing this as I designed this bird back in 1995, would have made quite an impact back then.

 I may treat landing gear as I did my Orion , with the ability to build as a fixed gear with shared gear leg components and leave out actuators until you (or your insurance company) are comfortable with the idea of operating a retractable undercarriage.

 Come see us at Oshkosh at the Demo, will have more info to share by then. Thanks for your interest.

I don't use the java required by that search engine but I found this interesting discussion with, what seems like, some knowledgeable people.

Looks more like the Berkut than a Long EZ, seems to me.  If you can get the strengths right with this new process, more power to you!

Beagle, this is a single seat canard. As far as getting the strength right, Jeff and Russ have been at this for a very long time.
Russ was the lead for the Vacuum Infusion team that fabricated the F-22 Raptor.

So glad they are being careful.  The Berkut Molds are available for sale if they want to move into 2 seats after they are wildly successfully...

Just a reminder.....
 By the end of next week we should have completed our project at Oshkosh with the reveal occurring on Friday morning, 7/29.
 Looking forward to seeing you there.

Well it was quite an experience and learning opportunity.

I got to Oshkosh Sunday around noon in time to help setup the tents where the demo was going to take place.



Monday was spent sealing and the molds (7 coats) and then adding another 7 coats of release.



Tuesday and Wednesday were spent installing the actual dry fabric and core materials. Those who were there can confirm, we experienced the typical EAA event weather and it did rain ..... a bunch on Wednesday.



Thursday started out raining at 8:15 AM. Temp was not as desired. We had 8 molds that we were infusing. The first four were using a urethane based resin system. This was used on the Star Lite aircraft fuselage. The Endurance epoxy system was used for the new canard design. All materials were donated by several different sponsors. One of those products was a combination peel-ply and flow media. We had this in the first four molds for the Star Lite. We discovered that it would not hold up when using the urethane resin.



In reality, this is the best situation when doing a demo like this. If everything goes right, you never learn the techniques to resolve the issues as they came up. Russ Emanis showed how to identify problem areas and then resolve them.



So after identifying the conflict between the urethane resin and the flow media, we set about pulling the bags off the other three molds and reverted back to the proven Greenflow and peel-ply. The parts were re-plumbed and we built new bags. By now we were getting pretty proficient at doing this but after all, we needed to get 7 more parts to infuse.



So of course it starts raining again. At this point we have 4 of the 8 infused.

Work continued until 10:30 to get all 8 infused. After the second wave of rain the temperature really dropped.



Friday morning comes and the parts are too green to de-mold. There was a review of everything we did during the course of the week. Once the sun came out, we moved the molds out from under the tents so they could warm up. By late afternoon they were pretty much cured.



Saturday morning the parts were de-molded and on display.

A picture of the upper fuselage half is pictured below.



So here's what we have:

We built the parts in a tent in really crappy weather conditions using new molds that had never had parts pulled from them and still came up with some beautiful parts.



Imagine what we could do in a controlled environment.

As you can see by the photo below, the flanges have not been trimmed off and the flow media & peel ply have not been stripped off yet.
 The upper and lower portions of the fuselage are just setting in place to get a feel for how this is going to look.

 The weight (as pictured) is 26 lbs.
 Of course this does not include the bulkheads, instrument panel, landing gear, etc., but those are pretty tough numbers to beat.
