What substances is contained in the solid fuel that the jet uses when using after burner?

Answer 1

The chemical composition of Jet fuel:
Jet fuel is clear to straw colored. The most common fuel is an unleaded/paraffin oil-based fuel classified as JET A-1, which is produced to an internationally standardized set of specifications. In the United States only, a version of JET A-1 known as JET A is also used.

The only other jet fuel that is commonly used in civilian aviation is called JET B. JET B is a fuel in the naptha-kerosene region that is used for its enhanced cold-weather performance. However, JET B's lighter composition makes it more dangerous to handle, and it is thus restricted only to areas where its cold-weather characteristics are absolutely necessary.

Both JET A and JET B may contain a number of additives:

Antioxidants to prevent gumming, usually based on alkylated phenols, eg. AO-30, AO-31, or AO-37;
Antistatic agents, to dissipate static electricity and prevent sparking; Stadis 450, with dinonylnaphthylsulfonic acid (DINNSA) as the active ingredient, is an example
Corrosion inhibitors, e.g. DCI-4A used for civilian and military fuels, and DCI-6A used for military fuels;
Fuel System Icing Inhibitor (FSII) agents, e.g. Di-EGME; FSII is often mixed at the point-of-sale so that users with heated fuel lines do not have to pay the extra expense

Afterburners. No more than about one-quarter of all the oxygen entering the front of the jet engine is actually used to burn fuel within the engine. To make the process more efficient, some jet engines are also equipped with an afterburner. The afterburner is located directly behind the turbine in the jet engine. It consists of tubes out of which fuel is sprayed into the hot exhaust gases exiting the tubing. Combustion takes place in the afterburner, as it does in the combustion chamber, providing the engine with additional thrust.

Hope that helps~

Answer 2

Jet fuel is essentially kerosene and the afterburner is just an additional combution chamber that burns a little more jet fuel. No solids.

Answer 3

I believe it's 'Hydrazine'.
