Hmm. Here is my 2 cents. I think we must look at Tesla in his time. Not ours. Look at his patents. Look at the people who cannot duplicate what he did. Look at what HE DID IN HIS TIME.Look at the people who lie about him.Look at the people who stole from him. Look at who profited from his...
hmm. I think dmac257's comment is most correct/interesting. I think he is correct about the difference in blade/ hub design at low wind versus high wind.While a variable blade is good- it does not address what blade/ hub design combo is best.Who has any idea about how efficient blade design is...
I agree with your comment on blade and hub design. There is likely a separate subject on wind turbine blade design.I am guessing you would have to build a "wind tunnel" to test propeller design. If you have a 36 inch prop., how big would you want to make the wind tunnel? 48 inch? I wonder if the...
hmm I can tell you that the highest force on the piston is at tdc in the overlap position. The less the piston weighs the higher rpm you can run. The less the piston weighs the less the connecting rod has to weigh. You would think rod angle is the limiting factor in rod ratio/ stroke. The 900...
Hi Any idea how much money has been spent in total R&D? Who is considered the tec leader in wind turbine design? How much work has NASA done that is directly related to this?
Gentlemen, I am very disappointed at the responses to my question.Only one person understood what I was asking. He quickly realized how difficult an issue this is.( he gave up) Here is an example of snappy answers to stupid questions; you want "area" at the peak? I am only a h.s. graduate. I...
NO I AM NOT LOOKING FOR AREA AT THE PEAK. No where did I say anything like that in any post I made. Yes I have seen Nelsons stuff. I am well aware of the benefits of a larger base circle. Please stop following me or responding to my posts- thank u- scott
I think you are wrong- if you were right all of the race engine builders would not be going to larger camshafts. I want to see the what the actual changes are and what maximum realistic diameters are. The dia. of the roller or flat tappet also has an effect Again, I am not interested in valve...
Gentlemen; Thank you for looking at my post. I guess I am not correctly asking my question. I think what I am really after is to compare 2 same size lobes made on different base circles. Let's assume both lobes are 220 degrees duration @ .050 lift with a total lobe lift of .5 inch. Let's then...
Hi JBA, I guess I am not conveying my request correctly. I want to talk with someone who has some knowledge about this and what software is used to look at these issues. Here is an example- A 1 inch diameter direct follower lobe with 220 degrees @ .020 lift- total lift .400 and a 2 inch dia...
Thanks for looking at this. My question pertains to two different apps. 1, I am building a billet head with overhead camshafts. I want to look at using larger dia. camshafts so I can have lobes ground with more lift. 2, I am designing a 90 degree v twin engine based on a 900 c.i. Pro mod. I have...
Hi the Harley forums should be able to give you some info. Generally the best advice is given by the people who sell exhaust tubing. Someone like Burns stainless or SPD will give you a recommendation if you buy the tubing from them You may be able to find someone who specializes in building...
Hi can anyone help me with info on the cause & effects of using a large 4" vs small 2" base circle camshaft. I want to know if I can use less rocker ratio and what software is used to look at lobe profiles- example a .5 inch lift lobe with a 2 inch base circle and a 1.75 rocker ratio (.875 lift)...
