v1.0.0a1

🌏Welcome to v1.0.0a1

An incredible pre-release of RocketPy. We encourage all users to install and test the new features.
To install it, you can simply run:

pip install rocketpy --pre

🚀What's Changed:

• Added support for LiquidMotor and HybridMotor 😁
• Various improvements were made to the Flight and Rocket classes.
• New features were added, such as the CompareFlights class for comparing flight plots, new nosecone types, and a RailButtons class.
• Several bug fixes were made, addressing issues with parachute lag, standard atmosphere, flight without rail buttons, and more.
• Dependency upgrades: update netcdf4 requirement and dropping support for Python 3.7.
• New utility functions and methods were added, including Function Operations and Piecewise Functions.
• Significant breaking change: ALL the code now is based on snake_case instead of the old camelCase format.

v0.11.1

Bug corrections

• @MateusStano noticed a bug that made RocketPy mistakenly use the wrong drag coefficient for each phase of the flight (powered vs. unpowered). This has been successfully corrected in #221 and is the main reason for this release.

Full Changelog: Projeto-Jupiter/RocketPy-Jupiter@v0.10.0...v0.11.0

v0.10.0

What's new?

• RocketPy can finally work with Environment date and time in any desired time zone. It's an awesome feature created by @FranzYuri in https://github.com/Projeto-Jupiter/RocketPy/pull/110 and #123. A new section in our Environment Class Example notebook was added to demonstrate how this can be used

Bug corrections

• Aerodynamic forces evaluation

  • We improved our Airfoil implementation in order to solve a bug with airfoil input data. See #140 to undesrtand the problem, and the awesome resolution by @MateusStano
  • Our aerodynamic was also improved to allow better calculation of roll moment of rockets with canted angle fins. See the great work done by @MateusStano on #116.

• Weird stable rockets with negative static margins

  • Issue #115 solved by @Lucas-KB in https://github.com/Projeto-Jupiter/RocketPy/pull/125, helped by @lucasfourier and @giovaniceotto
  • This issue only affected rockets which had one or more diameter reductions (such as tails), making them seem more stable than they should be, and caused problems from v0.9.7 until v0.9.9. New tests have been implemented to make sure this never happens again, making RocketPy significantly more trustworthy.

• Function class initialization

  • Fixed input name for some Functions instances initialized with int/float or callable by @giovaniceotto in https://github.com/Projeto-Jupiter/RocketPy/pull/141

Other improvements

• We are raising a warning when the user tries to use Environment Forecast Models without installing netCDF4 library, good work done by @skrobchik in https://github.com/Projeto-Jupiter/RocketPy/pull/127
• RocketPy now has a parachute.py, which was created by @FranzYuri in https://github.com/Projeto-Jupiter/RocketPy/pull/113. It was an enhancement in the organization of our Rocket class
• We are adding a SolidMotor_class_usage notebook in order to better illustrate how this class works. Initially created by @lucasfourier in https://github.com/Projeto-Jupiter/RocketPy/pull/42 and finished by @Gui-FernandesBR and @giovaniceotto

New Contributors

• @skrobchik made his first contribution in https://github.com/Projeto-Jupiter/RocketPy/pull/127, it is a huge pleasure to have you in our comunity Robert!
