Airbus HelicoptersReducing prototype costs by a factor of 4
From component and system engineering to real-time simulation
• Shortened hydraulic systemoptimization cycle by a factor of 3
• Decreased prototype costs by afactor of 4
• Avoided late delivery penalties“Being able to anticipate a problem is a significant source of cost and riskreduction.”
Nicolas Damiani, Expert in Simulation and Operational Analysis
• Ensure accuracy of plant and real-time hydraulics models• Enhance flight simulators’ fidelity

IRKUT builds Virtual Integrated Aircraft using a secure and optimizedmodeling process
Business challenges:• Predict subsystem and system behavior once
integrated into aircraft• Consider design options without mobilizing
considerable financial and human resources• Minimize the number of errors discovered at the
verification phase• Obtain optimal design within the shortest timeline
Keys to success:• Perform thermal analysis of the avionic bay• Assess system interaction early and accurately• Apply the VIA processResults:• Reduced modeling time by a factor of 5• Established a secured and optimized modeling process• Enhanced model, architecture and configuration
management
“Compared to our previous solution, LMS Amesimallows us to reduce time spent in building our mostcomplex models by a factor of 5.”
