Avro Cierva C30

Now in Spain is not possible left home for the Covid 19.
Long time ago I wanted to build a Cierva Gyrocopter.
I hope go out soon for test it.

I love everything in your buid.
Are the blades just foamboard or are they enfoced somehow?

Hi Rhaps:
Thanks a lot for your compliments.
The blades are of 3mm. foam board with a wooden nucleus .Its the philosopy of FT.
In my house I don't have the resources and the materials than in my workshop.
I will try attach some pictures for show the build of the blade.

 

[The Hangar]

That looks awesome!

 

[messyhead]

Nice model. I was recently thinking about whether it would be possible to build a helo from foam board. I guess you can!

 

[Parramon]

These pictures show the details of the blades. For picture I´m using a ice scream sticks but I used a firewall type wooden board for final blade.
I hope this will help.

Beautiful build, I hope it flies nicely as well. It looks like the rotorhead is fixed (as in its rotational axis non-adjustable), is it 3D printed? Are the blade grip angles adjustable?

Be well, I hope things improve for you soon.

Hi Varg:
Thanks a lot for your compliments.
The rotorhead is orientable. This is 3D printed, but is possible make some parts with firewall woodenboard type.
I don´t understand well you question about The blade grip. The incidence angle of the blades is neutral and is not adjustable but the blade grip needs a free articulation for free movement of blades.
Later I will attach a video.

I mean adjustable blade grips as in you can set the collective pitch by adjusting them. It is clear that it doesn't have a swashplate and therefore no collective pitch control, but I was wondering how you will set the collective pitch to the proper angle to get it flying. I have a couple of collective pitch helicopters and am trying to relate the rotorhead to them. Cool that it's 3D printed, if I were to build an autogyro I would print the parts as well since I print many things.

Hi varg:
Please have a look at this video. I think it will help.

The rotor head have the swashplate function (diferent than helicopter) but don´t have colective pitch. In the latest versions of Cierva gyrocopters they had a pitch control for improve the rendiment but isn´t necesary because the rotor runs like a wing.

There is something strange with video though, it is supposedly 7 minutes long but still ends at 5 mnutes.
Still, that was excellent presentation - crystal clear even when I don't understand spanish - gracias.

Hi Rhaps:
You´re rigth. the video goblins moved the audio track of the video. This morning I´m going to change the video.
Sorry for Spanish. In my english would be horrible.

 

[Parramon]

Sorry finally, the audio don't runs correctly with the image. I don't know whats happen . The original video runs correctly in my computer but when I upload it, the speed of audio track changes.

Hey, you are Spanish person building Cieara autogiro so Spanish is definitely ok

Thanks a lot. By the way I will try to make a new video about the parts of rotorhead, this time in english.

 

[varg]

Spanish is fine for me, I don't speak much but you showed how it works perfectly. Inventive solution, the whole shaft moves in a grommet and the system is hidden from view so it looks fixed. Thanks, Parramon.

You are welcome. We have to share the ideas.

First rotor with blades test. All it´s possible with foamboard !!.

I hope the lockout will end soon.
