Innovate for the future The aviation industry has an extensive innovation agenda. Market demands, such as increased safety and comfort, better fuel economy, reduced emissions and noise levels, and overall lower operating costs, are forcing the aircraft industry to rethink traditional engineering methods. Today, the industry as a whole is undergoing a transformation towards new design processes and better use of technology.

Managing a growing complexityThe most prominent examples of new technology are the use of composite material in airframes and the increase of electrically powered systems. Electrical systems significantly reduce the weight, making the aircraft much more economical to operate. But, these new technologies introduce the need to re-evaluate traditional system and subsystem design. Aircraft development becomes much more complex and interdependent. Managing this growing complexity throughout the supply chain is a major challenge that calls for profound innovation and a system-level approach.

Early aircraft maturityTo lead the aviation race, time to market is critical and therefore, achieving earlier aircraft maturity is a top priority for every aircraft manufacturer. Current aircraft programs accumulate immense amounts of rework. Making the right architectural and technology choices early in the aircraft program will significantly reduce rework and related costs. This requires an engineering platform that enables quick trade-off studies early on. Ideally, this early decision-making process will include dynamic, performance-based, system-level modeling capabilities during the concept phase. Such a tool will allow engineers to manage the complexity of highly integrated aircraft systems by obtaining the right requirements in time.

Solving the integration issueModern-day aircraft are a system of systems that dynamically interface with each other to perform a specific function. Recent aircraft programs have had quite a few structural and systems integration issues, which cause long program delays and tremendous budget overruns. The root cause of these integration issues is the aircraft requirement process itself. In most cases, requirements do not consider dynamic interaction on a system level. LMS International currently provides dedicated test, mechatronic simulation and engineering solutions to help both integrators and suppliers achieve earlier aircraft maturity as efficiently as possible.

LMS solutions for the paradigm shift in aircraft engineering The aviation industry has set the agenda for new, more economic and ecological aircraft. To succeed, new concepts and technologies need to be integrated into the development process while adhering to stricter program schedules. The current challenge is how to transform the engineering process, both on the integrator and supplier side, to design and certify the next generation of aircraft. It is no longer possible simply to build on existing aircraft concepts. The industry must introduce new design concepts and aircraft system development processes.

Why is a transformation towards model-based systems engineering needed now?From both the mechatronic simulation and testing perspective, it is important to make solid and accurate decisions regarding technical choices and system integration during the earliest phases of the aircraft program. Engineers must be able to analyze conflicting requirements and various interaction scenarios to anticipate any system-level integration challenges from the start. They also need to increase simulation realism and productivity for component and subsystems verification. They need to combine simulation and test to frontload subsystem validation and therefore advance the testing process for final system validation. There is also the trend towards model-based controls engineering using multi-physics subsystem and system models as plant models based on MIL, SIL and HIL development approaches. The industry needs a process to cover all of this and model-based systems engineering is the answer.

Does LMS have specific solutions to optimize the early stages of aircraft development?In a way, an aircraft is very much a “system of systems”. With increased system integration and interaction, system-level performance analysis has become increasingly critical. With this in mind, we have developed the LMS Imagine.Lab platform to include multi-physical modeling, validated simulation and multi-level system synthesis to help integrators find the right architecture.

LMS also delivers solutions for Virtual Integrated Aircraft analysis to optimize and validate integrated hydraulic, pneumatic and electrical subsystems performance upfront. Co-simulation between LMS Imagine.Lab and LMS Virtual.Lab form a scalable and open platform to model aircraft systems integration and check the “system of systems” performance well upfront. Most recently, LMS has developed a dedicated model and data management application that supports collaboration between different engineering departments for subsystem and system engineering. All these solutions are aimed at making the right technological choices upfront and preventing costly reworks downstream.

“By designing the ideal architecture upfront and

optimizing its functional performance, even before

geometry is available, engineers can even further

frontload the development process, mitigate risks

and avoid late stage changes.”

How does upfront systems engineering improve the integrator-supply chain interaction?Major aircraft programs are increasingly engineered on a global basis, involving an extended eco-system of suppliers. The suppliers design and develop sub-systems based on the aircraft integrators’ legal and technical requirements. To avoid integration issues and rework, the process on the aircraft integrator’s side needs to take the sub-systems’ dynamic interaction into account when defining the requirements for the supply chain. For example, landing gear performance will have to be defined, developed and validated in the context of the aircraft structure as well as the hydraulic and electrical power systems under a multitude of operational modes.

As part of the paradigm shift to model-based systems engineering, we will see more and more aircraft integrators using the synthesis capabilities in LMS Imagine.Lab to analyze upfront both the physical and logical subsystems interactions, including controls. This will lead to better technical requirement definitions and more clarity for the entire supply chain.

On the simulation side, how do LMS solutions increase realism and productivity for component and subsystem development?As systems become more complex, functional system analysis is not sufficient anymore. Engineers need deeper physical insight in how systems behave in order to secure the system function and performance. LMS solutions provide scalable capabilities to model systems at the required fidelity covering multiple physics. LMS Imagine.Lab is a rich system modeling environment covering Fluid, Electrical, Mechanical systems. LMS Virtual.Lab increases the model fidelity for the systems where a 3D representation is required. LMS Test.Lab complements this with experimental based acquisition and analysis technologies.

So better and smarter testing will also play a role in the paradigm shift in aircraft engineering?Going into the world of the unexplored, as one does when adopting new materials, design concepts and technologies, does lead to more testing to understand the physical phenomena. Validation testing is very

expensive. The trick is to be smart about how you combine testing and simulation. Using virtual models to prepare the test not only reduces test-related costs and risks, it cuts time off the test campaign itself.

A good example is the LMS solution for aircraft structural dynamics qualification. The LMS Ground vibration testing solution and its corresponding engineering services cover the process from pre-test structural dynamics simulation, to ground vibration testing (GVT), to the use of GVT results for calibrating structural dynamics models for flight flutter testing. It is recognized by specialists around the world as a key factor to accelerate the launch of new aircraft programs.

Our unique capabilities to create high-fidelity real-time simulation models, enable to frontload Hardware-in-the-Loop (HIL) tests. This capability could eventually result in the virtualization of the aircraft’s Iron Bird, what the industry refers to as a Virtual Iron Bird. This opens an entire new world of possibilities in terms of frontloading and validating integrated systems.

How does the LMS solution portfolio support the trend towards model-based controls engineering?When developing controlled or mechatronic systems, engineers cannot afford to wait for the physical hardware to be available to complete the controller development. Controls engineering tasks need to be frontloaded into the development program. The best option is to use simulation models representing the system that the controller will eventually run, or so-called “plant” models. In model-based controls engineering, the plant models are synchronized with the simulation models of the components and subsystems.

To do this, LMS’ simulation platforms feature unique functions to couple plant models with applications used for actual controls engineering. This can be done off-line or in real-time to support the entire model-based controls engineering process – from Model-in-the-Loop (MIL), to Software-in-the-Loop (SIL), and Hardware-in-the-Loop (HIL). This capability is a critical link between mechanical engineering and controls engineering for all types of controlled systems.
