I piloted gliders C800, Bijave, C 310, airplanes Piper J3 , PA 28, Jodel D117, DR 220, Cessna 150, C
Total Flight Time
About 500 h (FW + ultra light)
The original C30 had a clockwise-turning prop (when facing it in order to start by hand-pull). But that semi-reproduction has a prop turning the other way...


Here's is Arco, who also uses to write here in the RWF, in a detailed talk –three years ago– about the project. At the time, it was planned to make a reproduction, not a semi-reproduction, but that hasn't been possible...

Consequently, the dissymmetry of the tail should be opposite, while it is the same on the reproduction:

I know (Arco mentions that in his talk) that they planned to use a 'Rotec' 150hp radial in the 'full reproduction', and as that engine rotated 'the other way', they were going to modify the tail accordingly. For whatever reasons, it's apparently not the case with this semi-reproduction.
 
Hello,



Yes, we are an association (www.juandelaciervacodorniu.com) with the purpose to highlight the role of Juan de la Cierva in aeronautical technology. The main contribution ever to aeronautics by any Spanish and the father of the rotary wing concept.

The objective of the association is to make a real replica of the C-30 and to fly with it on the centenary anniversary of the first rotary wing flight which took place in Getafe on 23rd January 2023. We think there is no better way to promote our passion worldwide than flying with a replica in the same place and on the same day but 100 years later. It will surely be on all TV news around the world.

The association is a mix of autogiro enthusiastic and relatives of Juan de la Cierva. We are glad to have as members his only living daughter, Ana María de la Cierva, his grandson, Carlos de la Cierva, and his great-granddaughter, Laura de la Cierva, who is pushing everyone to achieve this project.

We think we have the expertise, skills, and information to do it, but we do not have the money, so the project is delayed. This is a long project. We planned that it would take several years to be able to fly safely in 2023.

Unfortunately, our country is not in the best economic shape and no private company is interested in supporting the project. On the other hand, government institutions are not willing to support it because De la Cierva´s thinking was conservative and our current government is from the left-wing party. This means that De la Cierva's political background is more important than his discoveries in the rotary wing world.

In this situation, we are looking for alternatives to keep alive this project. We found a Spanish homebuilder that is making a tractor autogiro by himself. You can see this in the photos and video in the previous post.

Its fuselage will "look" like a C-30, this is the only resemblance. The rotor is Magni and the engine is an old underpowered Continental engine. Now he is looking for a more powerful solution. We will help him as technical advisers and he will loan us the gyroplane to fly with it on January 23, 2023.

I already explained him how the horizontal stabilizer looked like on the original C-30 and how it works, so once he has the new engine he will modify the horizontal surfaces according to the final engine type (propeller direction and torque).
