Cordite (Balistite) Propellant VS SRB Propellant

[Aeed]

What is the best Propellant for long distances rockets ?

1-Codite Mixer of NG NC
2-SRB Mixer AP A POWDER

Cordite use for Amature rocket like Katyusha (250 Hectometers) and Grad (2000 Decameters)
SRB for space rockets (Powerful payload)

Any have more informations ?

Excess me for my bad English

And how do you propose to make the amount of propellant needed?

A katyusha rocket uses many kilos of propellant. Can you make kilos of NC and NG?

[sparkchaser]

NC & NG would be the easy part once you have the gallons of nitric acid you would need!

[Aeed]

katyusha long 12 Decimeter that's mean propellant weight at least 8 kilograms.
About Decaliters of NG can be made by Sand method to avoid explosion
The question is ---> what's the best propellants Cordite or SRB?

Defining Katyusha and Grad as "Amature" rockets is quite amusing.

Aeed, research this technical term: Specific Impulse. It's abreviated I_sp

Katyusha payload over 25 kilos of explosion it's definitely a mature

I think he's saying 'a MATURE rocket', not 'AMATEUR rocket'.

Yet another example of why proper grammar and spelling are important to prevent confusion. :rolleyes:
