Landing Gear Complete Virtual Prototype
The landing gear of a commercial jetliner is a mission-critical component. Its design and engineering considerations are immense, involving:
- Weight
- Minimum volume
- Cost
- Structural integrity
- Aerodynamic stability
These factors are all interconnected. Design challenges include:
- Reducing drag and noise
- Aero-elastic stability
- Articulation in a compact configuration
- Small radar cross-section signature
These challenges are interdependent through a multitude of complex physical relationships, requiring a unique simulation solution capable of integrating multiple physical phenomena.
ANSYS Simulation Tools
ANSYS brings these tools together in a single intuitive and comprehensive simulation environment:
- ANSYS SpaceClaim: Used for rapid pre-processing via direct modeling. It can handle all CAD formats and aids in fast model cleanup and parameterization. Design changes can be incorporated easily and intuitively.
- ANSYS Fluid Solutions: Used for accurate aerodynamic simulations, important for acoustics and aerodynamic load predictions.
- ANSYS CFD Solutions: Offers engineers high-fidelity turbulence models like DES and LES to predict complex phenomena such as turbulent coherent structures and acoustic wave properties.
Design and Simulation
ANSYS Fluid Solutions allow engineers to design a complex modeling environment by considering a range of effects. This promotes error-free design by developing complex multi-level models, focusing on:
- Technology
- Cost performance
- Human energy
This approach results in better outcomes when applying loads, such as external aerodynamic pressure loading, and understanding fundamental modes of vibration.
Aeroelastic Response
The aeroelastic response of the landing gear door can be predicted using transient dynamic simulations via one-way and two-way fluid-structure interaction. This enables engineers to understand stability and prevent dangerous phenomena such as flutter.
Radar Cross-Section Signature
By adding another level of physics, the influence of the landing gear design on radar cross-section signature can be determined, which is an important design criterion for low observables in military aircraft.
Control Software Integration
For effective simulation of the system, the control software C-code is integrated into ANSYS Simplorer to drive the kinematics of the landing gear. This integration helps in effectively identifying design issues early in the development cycle.
Durability Evaluation
Finally, all components are evaluated for their durability by performing fatigue life predictions using best-in-class ENCODE DesignLife.
