[edit] Why not merge this article with the Nose cone article?

I split the article from the nose cone article because it really focuses on the math involved during nose cone design. Lots of articles use seperate sections for this kind of thing. Ruleke 09:29, 2 January 2006 (UTC)

[edit] Copyright question

This page appears to be largely a direct copy of the following article, copyrighted in 1996: http://projetosulfos.if.sc.usp.br/artigos/NoseCone_EQN2.PDF - which is even listed in the references. Is there permission to use this? If not, I will consider marking as a copyright violation. --Knotnic 19:57, 12 June 2006 (UTC)

Please see http://myweb.cableone.net/cjcrowell/VCPMAIN.htm

This is Mr Crowell's site where he publishes the article stating everything on the site is freeware.

If you want, I can get an email from him, not sure where to post it or what the procedure is. --Ruleke 09:26, 13 June 2006 (UTC)

I have verified by email with Mr Crowell that the work is in the public domain. --Ruleke 11:31, 14 June 2006 (UTC)

Great - thanks for clarifying.--Knotnic 15:58, 14 June 2006 (UTC)

[edit] Create a comparative table?

The article is interesting but its not easy to discern which designs work best in what situations. Perhaps it needs a table at the bottom comparing the various designs and their characteristics.--Hooperbloob 20:41, 18 June 2006 (UTC)

Thanks for the suggestion. I have started a section for this. It's not an easy comparison though the table I put in place now is a good first guideline. More to come later. Ruleke 15:38, 2 November 2006 (UTC)

[edit] Why is a cone mischosen?

"A very common nose cone shape is a simple cone. This shape is often chosen for its ease of manufacture, and is also often (mis)chosen for its drag characteristics." Why is a cone mischosen? Does it have more drag than one would normally assume? Banaticus 08:27, 24 July 2006 (UTC)

The conical shape has a drag coefficient of about 0.5, which is very low. However, the turbulence created with this nose cone when fitted to a rocket causes the total drag coefficient to be the worst of the shapes listed here. Ruleke 08:51, 25 July 2006 (UTC)

So on subsonic propellor driven aircraft, a sharp conical nose is a better choice or would it still be better to go with a more rounded nose cone? 22:18, 27 July 2006 (UTC)
