| Summary: | The use of aircraft as a transportation mode is increased by time. Many aspects that need to be considered in the design process including aerodynamics, light weight structure, or other factors. Each aircraft that flies is subject to variation of structure load depending on the appropriate flight conditions. These structural load are caused by lift and inertial force.
In order to ensuring aircraft safety, we must concern on a safety regulation that have been established in accordance with the aircraft criteria. Each of load cases is analyzed to obtain the value of lift on each different flight conditions depends at a certain load factor and airspeed.
The author also developed some python programming modules to generate nodal load value in spanwise or chordwise direction. Lift and inertial forces are written includes shear forces, bending moment, and torsion differently in each node on wing. Load values for each cross section under each flight condition in the critical flight envelope to be showed in the composite diagram so that user could receive load limit value with a possible variation of flight conditions.
As a case study, a load analysis was carried out on the wing structure of a subsonic transport aircraft with 80 passengers in symmetrical flying conditions, The result obtained are the output of variations in the value of lift on the wings and tail, resulting in variations in the value of the nodal load on the wings. It can be seen in the error calculation that this analysis module is able to predict the limit load quickly with an error of less than 5%.
