The Numerical Simulation and Calculation of Aircraft Horizontal Stabilizer to Aerodynamic Forces by Using Visual Method

Abstract

Horizontal stabilizer is one part of lift wing structures, which can assure the security of aircraft stability and maneuverability. The paper discussed the visual method based on the numerical simulation and calculation of the aircraft horizontal stabilizer FEM model to aerodynamic forces. Visual method can make the designers understand the internal forces transmission between girder and rib, and help them finish the qualitative analysis of influence of structural-load carrying capacity. It can be used for evaluating the effects of size deviation during manufacturing procedure. It can help designers facilely beforehand measuring and judging the influence of load distribution on the aircraft horizontal stabilizer in first time on the war, when some part of the structures have been destroyed. By combination of visual method and background data, we can get a new complete system to help non-strength designers finish their work in strength condition, and create more value.
