AE771 — Rocket Propulsion

Propulsion textbook example problems for AE771 (Rocket Propulsion).

Problems are implemented as parameterized Python functions so that inputs can be changed and results are printed neatly to the console.

Running

Each file can be run directly. For HW2.py, pass one or more example keys to run only those problems:

python HW2.py          # all examples
python HW2.py 2-1      # Example 2-1 only
python HW2.py 2-2      # Example 2-2 only

python HW3.py          # Minuteman thrust/Isp plot
python HW4.py          # Ex 3-1 console output + Fig 3-1 plot
python HW5.py          # Ex 3-2 console output + Fig 3-3 plot
python HW6.py          # Fig 3-4 plot (k = 1.1, 1.25, 1.4, 1.7)
python HW7.py          # Ex 3-3 console output; Ex 3-4 console output
python HW10.py         # Acoustic resonance frequency console output
