WUADS 0.2.7

Conceptual aircraft design package with empirical and numerical methods

WUADS

Washington University Aerospace Design Suite (WUADS) is a Python-based conceptual aircraft design package built with two core goals: simplicity and extensibility. WUADS combines empirical methods with mixed-fidelity numerical models, enabling users to rapidly analyze aircraft performance across a wide range of configurations — from conventional transports to complex systems with alternative propulsion and unconventional geometries.

Features

• User Friendly Designer GUI

  WUADS aircraft designer GUI is designed to simplify the process of creating and editting WUADS input files

• Empirical Weight Estimation
  Component-level empirical methods are used to accurately estimate the aircraft's weight based on configuration and inputs.

• Vortex Lattice Method (VLM) Integration
  WUADS automates the setup and analysis of aerodynamic performance using the Athena Vortex Lattice (AVL) code.

• Aerodynamic Performance Analysis
  Combines VLM results with empirical drag models to evaluate overall aircraft aerodynamic efficiency and static stability.

• Mission-Based Range Estimation
  Supports custom mission profiles to estimate fuel burn, reserve fuel, and maximum range capabilities.

• Optimization-Ready Framework
  Rapid performance predictions and a modular structure make WUADS ideal for conceptual optimization tasks.

• Customizability and Extensibility WUADS is designed to allow the user to easily override the built in methods allowing for custom components, analysis methods, etc.

Download and Installation

WUADS can be downloaded like any other python package

pip install WUADS

The only complication is that in order to run a full aerodynamic analysis, Athena Vortex Lattice will need to be installed in the current working directory. Note that this just needs to be the "avl.exe". Alternatively, you can set up an environment variable which links 'avl' to the path of your avl.exe file. You can find the avl download on the site below.

Basic Usage

The basic syntax for using WUADS if fairly straightforward assuming you have already defined your input file.

from WUADS import Aircraft, weights_report, mission_profile_report

input_file = './inputs/aircraft.yml'    # Define the path to your input file
ac = Aircraft(input_file)               # Create the aircraft

weights_report(ac)                      # Generate a weights report
ac.mission.run_case()
mission_profile_report(ac)

The above code will load the aircraft input file, generate the geometry, calculate the weight, calculate the parasite drag, and populate the mission profile, and calculate the overall range of the aircraft. It will output 2 seperate reports one detailing the aircraft's weight properties and one detailing the aircraft's mission profile and range.

You have two seperate ways to create the input file. One is to edit the aircraft's .yml input file directly. This file is designed to be as readable to the user as possible and is not overly complex to use, however to simplify the process of creating these files, the designer GUI can be used. To launch the GUI, enter the following into the terminal or command line

WUADS 

Alternatively you can launch the gui with your input file instead of the default input

WUADS ./inputs/input_file.yml
