CT Special Supplemet 3 Missiles Propulsion Sytem Tables versus Equations

[snrdg082102]

Hello all,

Back when I first looked SS3-O(riginal) I ran into a problem when I tried to match 5G5 limited burn propulsion system table on SS3 page 13, listed in the Missile Identification example, and the equations.

Has anyone determined why the equations and tables don't match-up?

I've done my own checks and compared them to the Consolidated CT Errata v 0.7, which the exception of the Limited Burn Table cost, the corrections match my alterations to SS3-O.

Hopefully, the correction submitted to DonM for the Limited Burn Table cost is not out to lunch.

It's even worse than that.

There are 5 sources for cost and mass: the formulae and the charts in the errata, the formulae and the charts in SS3, and the formulae given in the text body of SS3.

None of these match.

Hello Piper,

Thanks for the reply,

I really do wish I had the CT CD so I could compare both SS3 and SS3-R. Since I don't have a copy I'm trying to match the tables, equations, and the text which is taking a while to do. I'm not very confident that any of my suggested correctionss are going to be accepted since they probably won't have canical support that a majority will agree with.

Well this gives me something to do and keeping out of serious trouble.

Do you have any suggestions?

Do you have any suggestions?

Nothing that's going to be very helpful, I'm sorry to say.

I personally pick text over tables. There's nothing to support this; it's just my own set of biases.

Morning Piper,

Nothing that's going to be very helpful, I'm sorry to say.

I personally pick text over tables. There's nothing to support this; it's just my own set of biases.

In this case the text and/or equations more closely support each other than the tables. Of course I usually go with the one that gets more bang for my credit meaning I did go with the text. Until I got a hold of the Consolidated CT Errata v 0.7 in which the correction in the text and equations supported each other.

Unfortunately, I'm back to the point that I'm going to use the canonical missile from Book 2 until I get a copy of SS3-R.

I appreciate the reply, have a good one.

Clearly errata must be viewed as more accurate than the original source that it is correcting. Do the tables, text and formula in the errata all agree with each other? That would be your starting point.

Hello atpollard,

In SS3 my approach was using the tables, followed by equations, and then text. Unfortunately, the three don't match in the article. The errata for the text and equations support each other. Checking the equations with the tables the only table not matching is the cost for limited burn systems. Unfortunately, I don't know about them in regard to SS-3R.

You have to remember: SS3 isn't being errata'd because a revision was done. SS3 is broken. Pick ONE of those, use it exclusively, and move on. I recommend using the formulae.

DonM explained that SS3 and SS3 material in Consolidated CT Errata v 0.7 from 2012 may not be the same as SS3-R which was published in 2011 and is part of the CT CD. Unfortunately, the CT CD and a whole lot of other material are on a wish list that I'm not able yet to start paring down.

I do use the SS3/Consolidated CT Errata v 0.7 equations but I'm not going to post any designs since there is a conflict between SS3, and SS3-R 2011, and SS3 updated with Consolidated CT Errata v 0.7 2012.

 

[DonM]

Yes, but Don has SS3-R open right now because of his own error... I'd like to update it for Marc for the next batch of CT CD revisions, and then bring all the differences between the original and the revision into the errata.

Evening DonM,

Thanks for the update.
