Hey guys,

Apologies for asking such a basic question, but I'm tired of coming up empty with Google. Does anyone know a reliable way to calculate max altitude of a supersonic rocket? Alternatively, does anyone have a comprehensive chart of altitude records by engine type going through O/P engines?

Our rocketry club (all high school students with a few mentors) has received funding from the school to begin testing propellant for our 50,000 feet attempt. Our plan is to build a 30,000 NS case-bonded finocyl rocket engine using many of the same techniques as Derik Deville. We will static test this rocket and fully characterize the propellant beforehand. So my incredibly basic problem is whether or not this mid-O engine can take our rocket to 50,000 feet even if we designed it perfectly. Every rocket altitude calculator gives me a different answer and I'm having issues with rocksim's custom engine input, which I will be re-visiting soon.

To summarize, will a 30,000 NS rocket engine with a 6" diameter send a well-designed rocket to 50,000 feet?

I hate it when I see threads where inexperienced members ask for help without any detail or seeming effort put into their posts especially when this community offers such extensive advice, so I tried to be detailed.

Any and all help is appreciated.
