Hello, I’m Olivier Broca with Siemens PLM Software.
Today, I am going to talk to you about our system simulation solutions helping you optimize
jet engines and their equipment.
To boost fuel savings and reduce pollutant emissions, the aerospace industry is looking
for innovative engine architectures, such as the introduction of the electric technology for instance.
To build greener aircraft, design engineers need to apply an integrated approach -
not only to the overall airplane design, but also to the engine development process.
To address these challenges, the LMS Imagine.Lab platform - and its aircraft engine solution
- allow you to define the exact boundary conditions for fuel, electrical power generation and bleed systems.
With access to more realistic boundary conditions for every onboard power network, you can assess
the overall efficiency of the integrated aircraft in various conditions, by reducing conservatism.
You can study the impact of aircraft mission requirements in terms of thrust, available
power and fuel consumption.
Not only does the solution help you predict the behavior of jet engines, it also supports
the design of engine equipment: including fuel systems, starters, bleed systems
and their controls, and engine control actuators.
LMS Imagine.Lab provides dedicated ready-to-use thermal hydraulics libraries.
And, its aerospace fluids database of standard and customizable components is based on aeronautics
standards to ensure model accuracy.
Now, let’s take a look at different applications of the aircraft engine solution.
First of all, using the functional engine representation, you can carry out high-level
analyses to assess combustion phenomena and pollutant emissions.
Moreover, LMS Imagine.Lab is perfectly adapted for early fuel system design.
It allows you to accurately represent components: such as pumps, high-pressure shut-off
valves or the fuel metering unit.
It also offers you the possibility to perform metering robustness and pressure pulsation
analyses, to ensure a constant flow to the combustors under any operating conditions.
The thrust reverser is another critical application.
LMS Imagine.Lab helps you ensure aircraft safety by assessing thrust reverser behavior
under various operating conditions.
It simplifies trade-off analysis to investigate electrical and hydraulic solutions, for instance.
You can also design other protection systems: such as fire protection and nacelle leading edge anti-icing systems.
In addition, the solution allows you to assess engine bleeding system efficiency, including
consumers like environmental control systems.
To increase fuel efficiency and decrease drag, the solution helps you correctly size the
bleeding system and obtain input for the analysis of thermal stress on bleed piping.
Now, I suggest we take a look at the bleed air application.
To maximize aircraft fuel efficiency and foresee potential integration issues,
the aircraft engine solution helps you perform pneumatic circuit and component design for bleed air
network and actuator modeling.
You can also identify and solve instabilities due to interactions between actuators and
the circuit, and optimize the design of valves working at high temperatures.
Finally, LMS Imagine.Lab supports a global representation of the engine lubrication system,
as well as the transient thermo-hydraulic analysis of the oil system.
It enables you to study heat exchanges in the fuel-cooled oil cooler during various
flight phases, as well as the bearing outlet temperature in order to avoid degradation issues.
To conclude, LMS Imagine.Lab helps you improve the quality of the jet engine and all its
equipment, while reducing development time and associated risks.
