Aeroelastic analysis

During the flight of the aircraft, the structure of the aircraft will be coupled with the surrounding flowing gas. This mutual coupling includes the inertial force of the structure itself, the elastic force, and the aerodynamic force exerted by the gas on the structure. Therefore, in the overall design process of the aircraft, it is necessary to analyze the trim problem, dynamic stability problem and the influence problem under the condition of external excitation, and obtain its dynamic characteristics and load characteristics quickly and accurately.

Solution

MSC Nastran has perfect aeroelastic analysis functions, including aerostatic analysis, flutter analysis, aeroelastic dynamic response analysis and aeroelastic optimization analysis. It can help to complete aeroelastic trim analysis, flutter analysis, aeroelastic dynamic response analysis and aeroelastic optimization analysis for different types of flights such as fixed-wing aircraft, unmanned aerial vehicles, rotor helicopters and missiles.

MSC Nastran has a variety of different aerodynamic calculation methods, including: dipole grid method, ZONA51 method, constant pressure method, Mach box method, piston theory, slender body and interference body theory, etc., can be subsonic, transonic and supersonic under different conditions of aerodynamic calculation and analysis. At the same time, the MSC Nastran has a flexible and open interface to support the introduction of external aerodynamic data to make the data more in line with actual use requirements.

The structural model of the aircraft can be created using MSC Apex/Patran, and the aerodynamic model can be completed using the professional aeroelastic analysis pre-and post-processing tool FlightLoads embedded in Patran, which can be seamlessly connected and integrated with the structural model. The FlightLoads interface is simple and friendly, in line with the user's actual use habits.
