Turbomachines and Aircraft Propulsion

Aircraft Engine Simulation for Reduced Noise, Improved Integration and Lightning Protection

Improved Turbomachinery Design Processes for an Increasingly Demanding Industry

Expected performances for modern aircraft engines have been steadily increasing. Because fuel costs are still one of the largest expenses for airlines, significant fuel efficiency improvements are required for new aircraft engine programs. In parallel, rising environmental concerns lead to new, more stringent regulations in terms of noise and gas emissions for new turbomachines.

Current market needs are pushing the aerospace propulsion industry to scale their production lines efficiently. Airline customers are facing reduced margins; new aircraft engines need not only better performance, but also to demonstrate improved maintainability, to increase their time-on-wing, and reduced development cycle cost.

Designing turbomachines for maximum performance, while verifying off-design operability and satisfying current regulations, is a multidisciplinary effort involving aerodynamic, structural, acoustic and thermal considerations. Aircraft propulsion manufacturers are scrutinizing all aspects of the aircraft engine lifecycle to support the aggressive cost reduction objectives expected by the market. This, in turn, is driving manufacturers to transform their turbomachine development processes and engineering software tools.

The capability to perform multiphysics analyses through all stages of the engineering design cycle is, therefore, of paramount necessity. The Dassault Systèmes SIMULIA portfolio offers aerodynamic, acoustic, thermal, and structural simulation capabilities with the superior connectivity of the 3DEXPERIENCE platform. Our simulation portfolio enables aircraft engine makers to make informed design decisions, optimize turbomachinery performance, increase certification confidence and compress their development timelines.
