Enhancing spacecraft qualification through DFAN simulation and testing
Accurately replicate launch acoustics to protect sensitive payloads and accelerate development timelines.
Before launch, extensive simulation and testing is required to understand whether the vulnerable spacecraft can survive the intense acoustic loads during liftoff and climb to space.
This webinar provides an in-depth look at an accurate acoustic testing method known as Direct Field Acoustic Noise (DFAN) simulation and testing. Unlike traditional reverberant chamber testing, DFAN involves surrounding a test object with a circle of loudspeakers that generate a direct acoustic field to replicate liftoff and flight noise conditions. DFAN can accurately replicate the harsh acoustics environment of rocket launches, achieving the same goals as conventional acoustic testing while offering advantages such as portability, shorter testing schedules and cost-effectiveness. This enables space, defense and advanced aerospace engineering organizations to protect sensitive payloads, reduce engineering risks and accelerate development timelines. Commonly employed for commercial, research and experimental purposes, DFAN simulation and testing will be explained in detail by experts from MSI DFAT and Siemens Digital Industries Software.
Key topics covered will include:
- Introduction to DFAN testing: An overview of DFAN testing principles, benefits, historical development and applications
- DFAN setup and control systems: A discussion on DFAN system setup, MIMO Random Control and pre-test analysis importance
- Practical applications: A focus on the successful collaboration between Siemens, MSI DFAT and key industry players to qualify spacecraft and instruments
This webinar will offer valuable insights into the flexibility and accuracy of DFAN testing, enabled by comprehensive digital twin simulation technology. From advanced simulation to experimental testing and validation, the integrated approach offered by the comprehensive digital twin will help understand how to enhance confidence in acoustic qualification processes and accelerate digital transformation across the industry.
