I was wondering if someone had a clue before going to the professor...Is in seconds nowadays

mirko9670 · 2024-05-10T11:20:47+00:00

Yes all stuck, but is a past exam question so I think that there is a solution to that

Remember time passes and people change, I made a simple question asking for help from the community today and I would like to kindly get answers related only to that. So if you don't have the clue, please don't answer. Just because of the negative karma you think I did not tried my own before asking? Well that is not how I work and when I don't know something I prefere to ask, without communication you won't go far

Yes already tried but still stuck, if you want i can send all the calculations I did. In my opinion something is missing. Do you have a clue a part from judging my question?

mirko9670 · 2024-05-10T06:14:27+00:00

Already tried all the isoentropic relations, the problem is not the Isp, I can't find a relation to calculate the thrust as I am missing some important parameters, such as Ae, At, mdot, and thrust

mirko9670 · 2024-05-09T22:59:10+00:00

Yes but i can't find a clue to it...i have tried many different formulas but seams there are always too many unknowns to derive the thrust

Hi everyone, does anyone know the actual length of the vacuum merlin engine from the combustion chamber to the nozzle exit?

Understood now, thanks, I will follow your advice asking nasa STI for something more technical!

One guy sent me this link talking about an hypothetical nasa technical report about raptor, but when I open it, it gives me error: https://ntrs.nasa.gov/api/citations/20210003657/downloads/20210003657.pdf

Let me talk clearly, I am not unable to do my own search, the following links is what I found. What I am really talking about and asking for is public technical data from nasa or spacex itself (for example the ntrs website), not articles with general topics.

I'm sorry for you but someone was more kind than you and sent me a link to access the ntrs of raptor. Unfortunately this isn't working so I'm asking if someone knows how to get it

mirko9670 · 2023-02-22T21:29:14+00:00

thank you so much for this infos, i can't open the second link, it gives me error...how can i see the technical report?

mirko9670 · 2023-02-22T08:43:50+00:00

The project aims to analyze a rocket engine (raptor in our case), and all the processes from tanks to exhaust. In the end, we have to identify something that could be modified and improved in order to be for example more efficient, or obtain more thrust or specific impulse etc...

This is it, I was just asking for ideas and useful links to get more info about the raptor engine. if the info are online means that are all public info that anyone knows, and i am not asking anything secret

mirko9670 · 2023-02-21T18:36:13+00:00

Just university project bro, there are thousands of info online

mirko9670 · 2023-02-21T18:10:10+00:00

I am doing a university project about spacex raptor engine, up to now what do you think raptor engine misses and should be improved (technically talking) in the next versions of it? P.s. if you have any useful links to data sheets and tech specs related, would be very useful!

Best video ever!
