AeroSandbox :airplane:
by Peter Sharpe (<pds [at] mit [dot] edu>)
Overview
AeroSandbox (ASB) is a Python package for aircraft design optimization that leverages modern tools for reverse-mode automatic differentiation and large-scale design optimization.
At its heart, ASB is a collection of end-to-end automatic-differentiable models and analysis tools for aircraft design applications. This property of automatic-differentiability dramatically improves performance on large problems; design problems with thousands or tens of thousands of decision variables solve in seconds on a laptop. Using AeroSandbox, you can simultaneously optimize an aircraft's aerodynamics, structures, propulsion, mission trajectory, stability, and more.
AeroSandbox has powerful aerodynamics solvers (VLM, 3D panel) written from the ground up, and AeroSandbox can also be used as a standalone aerodynamics solver if desired. Like all other modules, these solvers are end-to-end automatic-differentiable. Therefore, in half a second, you can calculate not only the aerodynamic performance of an airplane, but also the sensitivity of aerodynamic performance with respect to an arbitary number of design variables.
Getting Started
Installation and Tutorials
Install with pip install AeroSandbox. Requires Python 3.7+.
Alternatively, clone from master on GitHub and install with pip install ..
To get started, check out the tutorials folder here!
Dependencies
The fastest way to ensure that all dependencies are satisfied is by simply running "pip install AeroSandbox" in your command prompt. However, you can also install dependencies on your own if you'd like: see "requirements.txt" for the list.
Donating
If you like this software, please consider donating to support development via PayPal or GitHub Sponsors! I'm a grad student, so every dollar that you donate helps wean me off my diet of instant coffee and microwaved ramen noodles.
Bugs
Please, please report all bugs by creating a new issue at https://github.com/peterdsharpe/AeroSandbox/issues!
Please note that, while the entirety of the codebase should be cross-platform compatible, AeroSandbox has only been tested on Windows 10 in Python 3.7 via the Anaconda distribution.
Details
One final point to note: as we're all sensible and civilized human beings here, all inputs and outputs to AeroSandbox are expressed in base metric units, or derived units thereof (meters, newtons, meters per second, kilograms, etc.). The only exception to this rule is when units are explicitly noted in a variable name: for example, battery_capacity would be in units of joules, elastic_modulus would be in units of pascals, and battery_capacity_watt_hours would be in units of watt-hours.
Versioning
AeroSandbox loosely uses semantic versioning, which should give you an idea of whether or not you can probably expect backward-compatibility and/or new features from any given update. However, the code is a work in progress and things change rapidly - for the time being, please freeze your version of AeroSandbox for any serious deployments. Commercial users: I'm more than happy to discuss consulting work for active AeroSandbox support if this package proves helpful!
Contributing
Please feel free to join the development of AeroSandbox - contributions are always so welcome! If you have a change you'd like to make, the easiest way to do that is by submitting a pull request.
The text file CONTRIBUTING.md has more details for developers and power users.
If you've already made several additions and would like to be involved in a more long-term capacity, please message me! Contact information can be found next to my name near the top of this README.
