| May 28, 2019 at 14:20 | comment | added | Aerocurios | Yeah, I read the source and the first coefficient is actually negative. Also, yeah, I wish the transition from the sharp cone to the cylinder was smoother here. | |
| May 28, 2019 at 13:53 | comment | added | bukwyrm | About that image: a) Is the first coeficient really meant to be negative? ----- b) the graph shows no noses that are both sharp-tipped and smooth-walled, so they do not really support your question - #2 and #4 differ in tip and wall | |

| May 27, 2019 at 16:26 | comment | added | Jihyun | I didn't downvote, to be clear. I'm just saying that the answer I linked provides a very good explanation that partially clears up some conceptual questions. Any extra answers on this page should at least add to what @PeterKampf explains in his answer. | |
| May 27, 2019 at 2:51 | comment | added | Koyovis | Not a duplicate. This question states awareness of the difference between subsonic and supersonic. It is a well stated question and does not deserve to be downvoted. | |
| May 27, 2019 at 1:48 | comment | added | Aerocurios | The first answer mentions my first point above and the second answer mentions the second point, but writes in text that the skin friction drag is lower while supporting it with an image that says the form drag is lower. The former is supported by the erroneously wetted area argument and the latter is stated as fact without reasoning (I’ve yet to read Hoerner). Why is the form drag and skin friction drag of a blunter (maybe even hemispherical) nose smaller than for a sharper nose (even at optimal AOA) and why do gliders ignore it? | |
