#no need for vapor off nose cone during launch start.

No need for vapor off nose cone until we hit the speed of sound...and then it should be only brief as we break past the speed barrier.

not true

#

vapor can form at pretty much any speed depending on dynamic pressure, atmospheric conditions etc

yes sure of course! I must be stupid!

I forgot about the vapor cloud that forms around me when I walk around my back yard picking tomatoes.

#

I have had your comments on my ignore list for well over a year. I decided "hmm....I wonder what this guy I put on my ignore list has to say, lets see what the blocked message is. "

Stupid me. Won't make that mistake again.

Your suggestion is plain wrong, so I was offering a correction, no need to be a prick about it

I’m just gonna not comment on the little debacle above. But foggers is right. It does depend on external factors when the cone appears or if it does. It just tends to happen around the speed of sound. But does not coincide with the speed of Mach one.

Hey! I use this effect to also give the players the feeling of velocity as many other factors experienced in real life is not possible to feel or simulate. I am playing with a function that can generate volumetric clouds but its not great enough on performance yet

here is an example of vapor on the rocket and how brief it is as it passes that threshold.
https://apolloinrealtime.org/11/?t=000:01:02&ch=14

it comes and goes as it passes the barrier.
it does not stay....it does not happen right off the launch pad.

It does not matter how or when it happens...i know it happens...it just does not happen the whole flight though the atmosphere from the launch pad.

people are focusing on the nuances of the physics of when it happens and not paying attention to the title of my suggestion.

it does not happen right after launch and the entirety of the flight though the atmosphere.

but if petri wants to leave it for a feeling of velocity vibe. so be it. It's just not realistic. And thats why Isuggested this under the "realism" tag.

I am well aware of the variables needed for the vapor to appear. That is irrelevant to what I'm suggesting.

i'm not talking about this anymore. I made my point.

Your link there doesn't seem to work but judging by the timestamp I assume that's Apollo 11's Max Q. If so that cone is caused by a large pressure gradient over the surface of the rocket. There's a large pressure drop due to the large increase in velocity. Which is the feeling that Petri is trying to convey. In a gamified manner. I haven't looked at it in reentry for a while but I believe on 11 it lasted ~15 seconds. But regarding your comment on the post itself, it does state "No need for vapor off nose cone until we hit the speed of sound...and then it should be only brief as we break past the speed barrier." The bolded portion there is what Folgers and I are trying to correct you on. This is definitely relevant to what you're suggesting as it is what you're suggesting. So the whole "people are focusing on the nuances of the physics of when it happens and not paying attention to the title [content] of my suggestion." isn't really a valid argument to be having here. Lastly, I don't know why you've shown hostility towards both Folgers and me, primarily Folgers and I'm unaware of any previous drama between the two of you. But as a test pilot, you are a key representative of the Reentry development team. Act like it.

And I too think I have made my point 🙂

These are the people helping petri model some things like MTVC and trim and better AGC sequencing. These are the people that do nothing but study anything and everything apollo. These are the people that can read AGC code...

I am begging you not to burn the bridge of a person who is as valuable is folgers is.

#

These people literally are friends with the astronauts.

I saw this and was going to say that the steam forms differently on every flight depending on atmospheric conditions and on some rockets show them for a very very long time. But the other two already made the point ig.

he was just being technical

sullen lance
#

technical without understanding the intent of the suggestion.

#

You are right that steam is likely not going to form on launch. But he was correcting the part about the sound barrier.

#

I don't think he was being condescending or taking on negative demeaner towards your intelligence at all.

sullen lance
#

well that is not how i took it considering past experiences with him.

#

he was likely on his phone at work and didn't have time to cook up a proper response

#

folgers is a proper busy guy. So he is always short and to the point. Maybe you don't like that. But not once has folgers ever been a jerk to me or anyone. I mean, he does tell me to stop sending one sentence messages a lot because he is usually always on mobile, but that's just fair tbh. Folgers is the second nicest person I know.

#

You think maybe it's just a misunderstanding?

When you quote someone, you should understand the quote.

you primarily?!

You conveniently forgot to quote when I said primarily floggers. 🤦‍♂️

I don't know why you've shown hostility towards both Folgers and me, primarily Folgers and I...
vs.
"I don't know why you've shown hostility towards both Folgers and me primarily"

and then proceeded to misinterpret what I was saying... 🤨

Plus your use of people in your whole 'point' speech means there's more than a single person, sooooo? 🤔

**people **are focusing on the nuances of the physics

Also just read this and try and explain how the next couple of messages weren't also hostile..... 😐

It does not matter how or when it happens...i know it happens...[In reply to my comment]
I am well aware of the variables needed for the vapor to appear. ** That is irrelevant to what I'm suggesting.**
i'm not talking about this anymore. I made my point.

Who the hell said anything about you?
Feel free to put me on your ignore list.
You can join Folger on my ignore list.
I don't care who you people are.

Bolded portions are areas where you contradicted yourself, made no logical sense, or I personally just found funny

#

And let us all remember this whole thing started with Folgers stating

not true [line break] vapor can form at pretty much any speed depending on dynamic pressure, atmospheric conditions etc

Followed by you with

yes sure of course! I must be stupid! [line break] I forgot about the vapor cloud that forms around me when I walk around my back yard picking tomatoes. [next msg] I have had your comments on my ignore list for well over a year. I decided "hmm....I wonder what this guy I put on my ignore list has to say, lets see what the blocked message is. " [line break] Stupid me. Won't make that mistake again.

#

But I'm 95% sure you have blocked me by now for whatever reason you told yourself was valid. All because of a disagreement over vapor implementation in someone else's project. Nice 👍

||Wow, I sound like an asshole there at the end||
