Loads Kernel

The Loads Kernel Software allows for the calculation of quasi-steady and dynamic maneuver loads, unsteady discrete gust loads in the time and frequency domain, continuous turbulence as well as dynamic landing loads.

Applications & Capabilities

Loads Kernel is particularly suitable for loads analyses based on aerodynamic panel methods and enables a license fee free loads process. Secondary features include various aeroelastic analyses (such as the calculation of elastic derivatives, control surface effectiveness or a flutter check) to ensure a feasible aircraft design from an aeroelastic perspective. The software is publicly available on GitHub.

Recent applications and examples include a large variety of aircraft, ranging from a glider to large passenger transport configurations and from very slow and ultra-light aircraft to very fast and agile fighter configurations.

Tutorials & Examples

There is a growing number of tutorials, focusing on how to use the software. They include a short introduction on how to use Loads Kernel, a detailed simulation set-up, and the simulations and results of the trim, maneuver and gust loads as well as a the flutter check.
