SRP Rocket Recovery Simulations

Simulations for single-parachute-dual-rope rocket recovery.

Dynamic Rope Mass Landing Simulation

Plot the length of rope by which the main rocket body should extend past the nosecone to approximate the impact velocity experienced by the nosecone (and thus payload inside) after the main body lands (at higher impact velocity).

Rope-Mass-Negligible Simulation

Similar, but mass of rope is negligible allowing the simulation to run significantly faster. However, some precision is lost.

How to run

Run the following commands in your terminal:

$ git clone git@github.com:stasostyk/SRP-Rocket-Recovery-Simulations.git
$ cd SRP-Rocket-Recovery-Simulations
$ pip install -r requirements.txt

Then simply run the file with:

$ py dynamic_mass_landing_simulation.py

Parameters

Here are some useful parameters you can pass along to customize the simulation to your needs.

$ py dynamic_mass_landing_simulation.py --ask

To prompt for input parameters rather than using hard-coded values (for rapid changes).

$ ... --3D

To render a 3D model instead.

$ ... --3D-time

To render a 3D model with the z-axis as time, and density denoted by colour.

$ ... --isolate 0.05

To isolate a specific density and only display it (works in combination with all other features!).

$ ... -dt 0.1 # use a time-step of 0.1 instead

To edit the time-step. Warning: should be under 1s.

Here is an example of timestep 0.1 versus 0.05:
