Both forms are valid, but one is more representative than the other.
There’s been no contradiction, we just haven’t been understanding what the other has been saying.
Sure, but that requires a little explanation first.
“Acquisition costs are part of life-cycle costs and embrace research and development (R&D) and production costs. For any class of equipment, development costs tend to vary in proportion to unit production costs. Total acquisition cost comprising both development and production costs can be estimated with the following equation where TC is total acquisition cost, R is the ratio of development cost to unit production cost, N is the number to be produced and P is the unit production cost. TC=(R+N)P” from The Economics of Defence Policy, Pg 18.
And it should be noted, those numbers are never fixed, but can be constantly changing on an annual or even monthly basis based on a whole slew of other variables that can alter/affect the cost estimate. Just one, depending on what your initial labor costs are whether low, medium or high and how inefficient or efficient your workers are able to take advantage of learning curves will have an direct impact on what the stated value of both R and P of that variable are. If you go from low to medium labor costs in the following year or two, that has an effect, while the inverse equally applies going from medium to high.
One formula would be used to calculate a single variable whose solution would be used in the next formula to enable further calculation to eventually arrive at a calculated estimate. This isn’t a difficult math concept to grasp considering you’ve done something similar not that long ago. Only this time, the formulas apply to economic theory and not engineering.
Unless I’m mistaken, the two are interconnected and what are whole discussion has been about.
How you would enter that as a definable numbered variable I’m unsure of at this time, but the passage of time + the number of technical faults, glitches and delays would in my opinion be a good place to start.
From everything I’ve read on the subject so far, FTR beyond what’s found on Wikipedia has lead me to conclude the 2K12 Kub {SA-6 Gainful} doesn’t use an identical propulsion scheme as proposed for the Gnom.
As far as I can tell, given the vagueness that surrounds the term “Air augmented” at times, both you and Tripbacon have been equating the term Air Augmented as meaning the same thing as “Integral Rocket Ramjet”. As to date, I’ve found no evidence supporting that conclusion and some evidence that actually the two terms imply very different things in how they function.
I’m greatly simplifying what I’ve found, but basically an Air Augmented system means both the rocket and the ramjet are working in tandem in one fashion or another. An integral rocket/ramjet means exactly that, first the rocket fires, burns out, then the ramjet engages, three separate actions and never together in tandem. Furthermore, if one is observant enough to notice like I was, never is the SA-6 referred to as an Air Augmented rocket, it’s always ramjet or integral rocket/ramjet. Now look at the Meteor missile, when described it’s always as an Air Augmented ramjet rocket.
That’s a clue if there ever was one, but it’s nice to see Confirmation basis at work making us oblivious to the obvious.

In all your research, you weren't observant enough to notice that?
1. The booster fires.
2. The empty booster casing becomes a ramjet combustion chamber.
3. A second rocket (the gas generator) spews fuel-rich gas into the ramjet combustion chamber, where it mixes with air and combusts completely.
4. zoom
The Meteor differs in some details, like having a throttleable gas generator and boron rather than magnesium fuel, but it's the exact same principle.
Gnom differed in having a separate booster and ramjet chamber.
In all three cases the air is augmenting the sustainer motor, not the booster.

New Vihenia is free to copy the SA-6 propulsion system, but they won’t be getting that sweet ISP their after.

The Joke's on you, in your rush to be right you failed to image you could ever be wrong. I wasn't bound to such limitations since from the start I was unsure which answer was the correct one and have been merely seeking an objective truth since then. It took some time, but I figured out the truth.
Which, is why it is indeed funny you think the SA-6 and Meteor missile operate in exactly the same way, when any person capable of reading would be clearly able to see that they don’t on some very basic principles.
Here’s the clue, if the rocket motor {Booster} isn’t augmenting the ramjet {ramcombustor} then it isn’t an Air Augmented propulsion system, hence the name. This is why the Gnom was projected to have a separate additional rocket booster. Finally, observe how in the SA-6 the rocket booster becomes a ramjet chamber once the rocket booster has been expended, hence why it’s called an integral rocket-ramjet. No rocket booster for ramjet, no air augmentation. The gas generator step is irrelevant in determining the type of propulsion system whether air augmenting or not.

I am unsure on what exactly you are trying to do?
I think the 9 years is adequate to represent whatever snags etc that might happen.
With your scheme you are basically telling me to actually build one which i wont be able, and you wont be bothering doing so too as well as your research.
Now you tell me should i input 9 or 100?
What is everything you read so far? Like seriously. Meteor works exactly the same as SA-6 with the only differences is that Meteor have valve in its gas generator to control the fucking thrust. Something which SA-6 lacks. Yet both works the same.
1.Rocket booster ON.. kicking the missile into Ramjet operating speed
2.Rocket booster exhausted.. The room left by the rocket now become a combustion chamber.. or in Solid fuel one become mixing one as the gas generator starts burning and sending its fuel rich particles which then mixed with air from inlet and perfect the combustion, producing thrust.
That's how it works and it works the same way for Meteor and SA-6. Like WTF.. how do you think SA-6 missile propulsion works?
If you REALLY... and REALLY doing your research it would be very obvious that they works the same manner and the same manner as the one i devise for Except in my scheme, the ramjet/air augmented and 1st stage of rocket booster are ejected once they run out of propellant.
This part came from you, I'll be honest it is ridiculous.
So you mean they work at the same time? Then it can be called air augmented rocket?

Everything I’ve said on the subject has merit, you’re just at the part where it doesn’t quite make sense to you and you’re getting frustrated, I feel your pain because I’ve been there before. While, I can’t post a calculated amount since I have no idea on what the variables to enter into the formula would be specific to your nation, I can post three links that almost word for word state the same thing I have been saying, I can only advise you to take your time and read them carefully.

Since, this part of the discussion is going in circles and you have no clue what I’ve been trying to convey, here’s a simple compromise I propose.
For the number of developmental years as an input, just put 10 and let’s move on.
For the last part of your post quoted directly above, I answered in my reply to Tripbacon since you two have taken the exact same stance and I don’t feel it necessary to repeat myself.
I’ll only add this, if you still feel I’ve reached the wrong conclusion, I’ll post every single source I consulted and you two can hash out an answer amongst yourselves.

Austrasien wrote:The gas generator is what an air augmented rocket is. An oxidizer-poor rocket that produces a fuel-rich exhaust that can be combined with the incoming air stream to combust more completely. A very simple air augmented rocket would be a hydrazine monopropellant rocket (gas generator) feeding its exhaust (Nitrogen and Hydrogen) into the combustion chamber to mix with oxygen in the incoming air collected by the inlets. The resulting oxygen-hydrogen combustion has a much higher ISP than hydrazine decomposition alone or even pure hydrogen-oxygen rocket fuel because the oxygen in the second stage is externally supplied.
The booster is a completely separate rocket motor which may or may not be physically inside the combustion chamber of the ramjet or ram rocket. Its main purpose is to accelerate the missile to a velocity where the ram intake will actually suck in a useful amount of air, so it would be pointless to try and augment its operation. A booster is not strictly necessary to operate an air augmented rocket though, it is mostly a concession to the practical limits of ram-air intakes. If you have a method of supply intake air even at low/zero forward speed it could be dispensed with entirely.
Austrasien wrote:You are apparently reading jargon without understanding it (something that seems to come up a lot here these days, recognizing the words being used is not the same as knowing what a particular jargon is signifying) and are parsing its meanings in absurd ways i.e. concluding the presence of the rocket motor which is being augmented with air (the gas generator) has no bearing on whether or not something is an air augmented rocket/ramjet... but the functionally and sometimes physically self-contained booster stuck on or in its ass is what really decides the question.

Everyone can download and view the paper, see how the author define what an Air augmented rocket is and you can compare the damn thing with Meteor and SA-6.
See the Red box particularly.

So, it's nothing more than an utterly meaningless bullshit term with no specific meaning? Gotcha… So, if I change a few words of that sentence around to basically say the same thing would I still have the correct definition?
