A Streamlit app for generating 3D model of the UAV wing console

UAV Wing Console Generator

Rectangular Wing Console (v1.0)

Streamlit app based on the CQ-UAV library for generation of UAV components with CadQuery and SplineCloud.

Mathematical Model of The Wing Console

Assumptions

• considered uniform distribution of pressure along the wing span (which is not true in reality);
• UAV pitch angle = 0, meaning horizontal flight mode with arbitrary angle of attack;
• only the wing box section accepts aerodynamic load, which is applied along the central line of the wing box;
• pure box bending is considered;
• wing console is fixed on one of its ends, another end is free;
• wing materials are isotropic.

Geometry

Wing consists of three main parts: three-chamber box compartment (inner body), shell and interim body (XPS foam or other low-density material)

Geometry is automatically reenerated based on the airfoil type and wing size.

Airfoil data

Airfoil data (profile geometry and aerodynamic coefficients) are collected from the open SplineCloud repositories with the script from the cq-uav library. Airfoil shapes are approximated with smoothing B-Splines, while sharp tails are thickened to avoid malformed geometry.

Running Locally

1. Clone this repository with git.

2. Open terminal and cd to the cloned repository.

a) Using docker-compose (recommended)

3. In terminal

docker-compose up --build

4. In browser go to http://localhost:8501/

b) Using virtual environment

3. Create virtual environment

python -m venv venv

4. Install dependencies

source venv/bin/activate
pip install -r requirements.txt

5. Run the streamlit app

streamlit run app/app.py

6. A browser window (tab) with the app should appear.
