Load Identification On Under-Wing Stores During Deck-Landings

The goal of the current study is to estimate the limit load an under-wing store can endure during a critical maneuver in military aviation namely deck-landings. In the current work, load identification is carried out using a new method, different from what Dassault Aviation’s engineers used to apply for this kind of study. The main asset of the new method is the use of a refined finite element model in order to simulate deck-landings and directly estimate loads that actually go through the fixing mechanism of the under-wing store. As a consequence, the general finite element model of the aircraft has been adapted for this study. Indeed, it had to be locally refined to reflect as much as possible the real geometry of the fixing point area. Then, a calibration phase has been carried out, using gauges, both settled on the aircraft structure and on the model. Thanks to this, numerical simulation results can be compared to test campaign ones and, finally, the load identification becomes possible.
