Overview
QBlade
QBlade gives you a powerful, open-source environment to design and simulate wind turbines from the ground up. You can create custom airfoil data, integrate them into rotor blades, and perform complex aero-elastic simulations to see how your designs handle real-world conditions. It simplifies the transition from initial blade geometry to full-system performance testing within a single graphical interface.
You can use it for both horizontal and vertical axis wind turbines, making it a versatile choice for researchers, students, and engineers in the renewable energy sector. By providing tools for structural modal analysis and turbulent inflow generation, it helps you identify potential failure points and efficiency gains before moving to physical prototyping.
Unreal Engine
Unreal Engine provides you with a complete suite of creation tools for developing real-time 3D content. Whether you are building a high-fidelity AAA game, a cinematic film, or a complex architectural visualization, you can manage the entire production pipeline within a single environment. You get access to a powerful world-builder, advanced lighting systems, and a robust physics engine that brings your creative visions to life with stunning realism.
The platform is designed to scale with your ambitions, offering a flexible environment that supports everything from solo indie projects to massive enterprise simulations. You can take advantage of the source code access to customize the engine to your specific needs. With a vast marketplace of assets and a global community of creators, you have the resources necessary to solve complex development challenges and accelerate your project timelines.
Overview
QBlade Features
- Airfoil Design and Analysis Import or create airfoil geometries and use integrated XFOIL functionality to calculate lift and drag polar data for your blades.
- Rotor Geometry Builder Design complex blade shapes by defining chord, twist, and airfoil distributions along the span for both HAWT and VAWT configurations.
- Lifting Line Simulations Run unsteady lifting line simulations to visualize wake development and calculate aerodynamic loads on your turbine in real-time.
- Aero-Elastic Coupling Connect aerodynamic forces with structural dynamics to simulate how your turbine blades bend and vibrate under various wind loads.
- Turbulent Wind Generation Generate realistic, three-dimensional turbulent wind fields to test how your turbine performs in unpredictable environmental conditions.
- Prowim Integration Utilize the integrated Prowim module to analyze the performance of offshore floating wind turbines and their mooring systems.
