Project Caelus: Liquid Rocket Engine - Pt. 1: Propellant Selection Using CEAgui

A basic introduction to the process of propellant selection on an amateur liquid rocket engine, and how to get useful data from NASA's open-source combustion modeling software, CEAgui (www.grc.nasa.g....
PROJECT CAELUS: A non-profit, high school based liquid rocket engine program. Our goal is to develop a liquid-fueled rocket that can reach the Karman Line by the summer of 2021. Visit us at projectcaelus.org.

Thankyou so much for sharing ur knowledge in cea and basics of desigin considerations. Thankyou once again.

[@jasonchen5761]

Krishna Kanth Dasari Thanks for watching!

[@blazgrabnar4232]

17:00 you predicted RocketLab's reuse program
Also great video! Thank you

[@thecros1076]

can we get the python code for calculating the measurements please we need it.

[@ARJUNTHEAIREBENDER]

Hey Jason, Great video, thanks a ton 👏🤝. I am trying to build my own liquid propelled engine, would love your suggestions. Is it possible to connect?

[@brocklydoodle]

I'm just starting to learn about Rocket Nozzles and maybe this is a silly question but how do you come up with your chamber pressure when you started entering values into CEA?

[@jasonchen5761]

Don't worry about silly questions! Everyone starts somewhere. Chamber pressure is normally a design specification - you pick it based on what you want your system to accomplish, and based on the resources available to you. For example, if you only have access to basic materials and efficiency is not a primary concern, lowering the chamber pressure might be a good bet. Normal ranges for chamber pressure of small (around 1-10 kN class) engines are normally anywhere between 1-5 MPa. Anything above that can get very dangerous for an amateur.

@@jasonchen5761 Hey thanks! Ya that makes complete sense now that you say that. Thanks again for sharing, theres not much information out there for figuring out how to use this software.

[@renanalmeidadesouza6386]

my program isnt printing out the results, do you know why?

[@takudzwamashamba7453]

same with mine. Did you finslly fix it? it says Output file:null NOT found.etc

[@nerdcm355]

The link does not work

[@jasonchen5761]

It should work now just updated it

[@thecros1076]

please please please can you give me the code for calculating the dimensions of the engine

[@vamshi3446]

can u provide the link to the cea software plz...
