Hello, I’m Stéphane Mouvand with Siemens PLM Software.
Those who experienced a hard landing during a commercial flight understand the importance
of the landing gear system, and the necessity to design reliable landing gears.
I am going to give you an overview of how our simulation solutions contribute to this objective.
Developing eco-friendly and cost-efficient landing gear systems are critical for fuel
consumption and carbon emission reduction during ground maneuvers.
Also, an airplane’s operational performance can be greatly improved, by reducing the time
required to cool down brakes, or by improving the aircraft drivability and handling.
New propulsion technologies using electric motors mounted on aircraft landing gear wheels
or towing tractors have already emerged!
The LMS Imagine.Lab platform and its landing gear solution enable you to assess the entire
landing gear system, including performance analysis for required functionalities, such as:
landing, extension and retraction, braking and steering systems.
LMS Imagine.Lab supports the multi-domain nature of landing gear systems: hydraulics,
mechanical, electrical and thermal.
It also allows you to consider the integration of the overall system interacting with the structure.
With LMS Imagine.Lab, you can now ensure the reliability of landing gear systems, even
under hard landing conditions.
You can also assess proper structural integration of extension and retraction systems, and the
robustness of the braking system, even in case of a rejected take-off.
Let’s start with extension, retraction and suspension systems.
With LMS Imagine.Lab fluid, thermal, planar mechanical and electrical libraries, you can
easily model multi-domain components when working on innovative extension, retraction,
and suspension concepts.
Our solution allows you to accurately size hydraulic systems and components to meet dynamic
loads envelope requirements, while running fewer physical tests, and reducing development
time, and, therefore, costs.
The landing gear solution is also suitable for enhancing braking performance.
It helps you reduce the time required to stop the aircraft, as well as risks like tire bursting, for instance.
You can also asses multiple technologies to achieve the right tradeoff.
You can consider various design options: steel, carbon or ceramic brakes; hydraulic or electric actuation;
as well as different options for pump and electrohydraulic valve design
of anti-skid systems.
In addition, LMS Imagine.Lab is of great help for steering system design.
Not only can you develop single components such as servo-controls and actuators,
you can also validate component integration and control strategies.
Moreover, tire shimmy issues can be reproduced and solved.
Finally, LMS Imagine.Lab helps you optimize aircraft handling and drivability performance
at concept phases.
It also enables you to perform innovation studies, such as the green taxiing concept.
Therefore, LMS Imagine.Lab becomes your ally in designing landing gears and addressing
engineering challenges posed by physical tests, costs reduction, sophisticated technologies
, as well as safety and safety requirements.
Thank you for watching.
