When I am entering vaules to my float variables some of them are returning wrong huge numers. For example I entered 0 and it returned 916455424. Please can anybody tell me the reason or solution?

Hi, I want to make a nozzle for my rocket and I have problems with defining the diameter of the critical cross section of the nozzle. Normaly it is calculated from the area ratio, I know that the value of the area ratio for fast burning rockets is between 100 - 200. But ... it seems to me to much because with this value of area ratio, the critical cross section should have only 3 mm. I don´t know what to do. Thanks

Oh my god thank you a lot this is awesome ... I will be translating this for a while but thank you.

Yes, but I have seen so many equations of this reactions with different products and I don´t know what products are the right ones.

Hi, please can someone help me? I can´t explain why is 3:2 the best ratio for rocket. It is insane excess of sucrose, so HOw does it work? What equation describe this reaction? Thank you.

Hi, I think I can give you a little help. I think that the ratio between 3:2 and 2:1 is ideal. (2:1 - work better for different additives). Power of your rocket fuel you can increase by some additives such as: pyrolytic aluminium powder - increase temperature in the combustion chamber so the reaction will run faster sulfur - also intreases temperature .. and it is doing something else, but i wont know exactly what it is but the fuel will produce bigger thrust Fe2O3 - this will help the most, it act like catalyst and increases the burn rate. and you can add only 1g for 100g of fuel and it will be 60% faster

please could someone tell me why I shouldn´t caramelise the sugar? How does it change it´s burning properties?
