Dextrin, red gum and phenolic resin replacement and recalculation

[MinamotoKobayashi]

As suggested by Carbon796, I'm recalculating all the fuel values of Jopete's stars.

But before to waste again kilograms of stars (see also: "Jopete's purple stars ruined by heat"),

I need to be sure that my next batches are perfectly fuel balanced.

So, my first try is to make Jopete's only alcohol based red2 stars.

The original Jopete's formula (for a batch of 100 grams) is:

24 Potassium perchlorate

24 Strontium nitrate

11 Strontium carbonate

10 Red gum

12 Parlon

15 Magnalium, 230-mesh

04 Dextrin

100 Total

Conversion of the Red Gum into Phenolic Resin: (10/100) x 83 = 8,3.

Conversion of the Dextrin into Phenolic Resin: 4/2 = 2.

The exact amount of the Phenolic resin to be used should be 10,3, so the resulting new formula is:

24 Potassium perchlorate

24 Strontium nitrate

11 Strontium carbonate

10,3 Phenolic resin

12 Parlon

15 Magnalium, 230-mesh

100,3 Total

Can anyone confirm my calculations before to proceed to make a new batch of red stars alcohol based?

RG .10 + 1/2 of the dex valve (.02) = .12

 

100g x .12 = 12g RG

 

Convert RG fuel value to PR

12g x .83 = 9.96g of PR

 

The 10.3g value of PR, would have been more than close enough. Colors generally display better, in a slightly fuel rich environment.

 

You can see that in this formula. Subbing the RG for PR 1:1 and just dropping the Dex entirely. Would have worked perfectly fine.
