I would not insult or run you down for attemping to improve yourself in a field that I knew and you did not. Lay off. I want to learn. I have done nothing to you.

Thank you Mr. Garvin. I believe I'll start with the tricycle (simpler texts) and work my up the more advanced stuff. I would be interested in what you think of this website. http://www.dynamicflight.com/aerodynamics/basics/ I have just started to study it and was wondering your...

Thank you sir. I will take a look at it. I am looking into the more technical side as well as the practical. What I want to do is build a small helicopter, FAR 103 compliant. This might be a little on the small side for you but it's big enough for me. Once again, thank you for your time. Jerry L

As I stated earlier I am trying to learn. Thank you Mr. Garvin, I know form your ealier posts you think that I should attempt this but you aren't telling me can't do it. You are telling to learn the subject first which is what I am trying to do. It is impossible for me start on it any time...

I am not wasting your time. You chose to start this exchange therefore you are wasting your own time. Yes this is a serious technical forum I suggest you look back at your posts on this forum. Ummm yes very technical, in fact I find it hard to understand them care to clarify for us non techies...

I never said that I was Qualified to design a helicopter. I said I was going to build one. I am not going to start on it soon. I said that I was learning so I could. This is not helping me reach my objective and is only marginally on topoic so good bye.

It doesn't matterr to me if you take me seriously or not. I am studying what I can about helicopter aerodynamics and flight, including the FAA Helicopter Flight Handbook and Nasa pages on aerodynamics

I can't show you any calculations as I do not have enough knowledge of aerodynamics to produce them. Never the less, one day I plan to build a helicopter. I don't know how long it will take to scrape up the money and information but I intend to do it. Until that time I learn what I can and...

Yes, Cyrus you may know all of the physics behind helicopter flight but do you want to deny others who don't a place to do it. I believe you would agree that a LOT of talk would be a good ideal before attempting to start a build. It would save a lot of time and possibly lives. Do you consider...

After some research on NASA's website I found it is almost impossible to calculate the stall angle for an airfoil so thanks anyway. Jerry

I don't agree that this thread should be closed. Any non distructive (homemade rpg not being one of them) project that open the mind to solve a problem is benifical. It gets someone thinking outside of their normal processes and perhaps gets them into an area that they would not normally...

How would you calculate the stall angle for the main rotor airfoil. You wouldn't your collective , cyclic total pitch angle to get that high. Stops to keep the pitch within a proper range wouldn't be that hard, but how do you calculate that range. Some of you might want to check this site...

I apologize for my Ignorance. I am not an engineer or helicopter mechanic. I had not heard of that helicopter design and was concerned about the increased stress on a motor driven main rotor, since it is the only thing holding the craft in the air. After having been informed about the Cheyenne I...

It's been a while since I looked at them. My memory was faulty I have removed that error. getting old I guess. (Regulation language causes brain Damage!) Thank you for the correction JerryL

Sounds almost like an auto-gyro, except for the vertical take off. are you familiar with the principles of the auto-gyro? It's main rotor is not motor drive but driven by the forward airflow. I don't know about a prop pushed helicoper. A small company around Wichita Falls Texas is is working on...
