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.
Windographer
Windographer is the industry-standard tool for analyzing wind resource data. Whether you are working with data from met towers, SoDAR, or LiDAR systems, you can quickly import raw files and perform complex quality control. The software automatically identifies data gaps and anomalies, allowing you to flag or filter them with a few clicks. You can then generate high-quality graphs and tables to visualize wind shear, turbulence intensity, and energy production potential.
You can use the platform to streamline your entire pre-construction wind assessment process. It handles massive datasets with ease and allows you to export cleaned data directly into wind flow models like WAsP or WindSim. By automating repetitive data cleaning tasks, you save hours of manual work while ensuring your wind resource assessments are accurate and bankable.
