Problem
Spacecraft and launch‑vehicle components require high‑intensity acoustic qualification to survive launch vibrations, traditionally performed in large, expensive reverberant chambers. Building, operating, and maintaining such facilities incurs significant capital and schedule costs, and the tests are limited to fixed locations. Consequently, program timelines and budgets are constrained by the need for specialized acoustic test sites.
Solution
MSI DFAT offers a direct‑field acoustic testing (DFAT) method that replaces reverberant‑chamber tests with a portable, modular speaker array capable of generating a controlled diffuse sound field from 25 Hz to 150 Hz at levels exceeding 150 dB. The system uses zone‑controlled electro‑dynamic loudspeakers and true multi‑input multi‑output (MIMO) control to achieve uniform acoustic loading without standing waves. Because the equipment is fully mobile and supplied with power, data‑acquisition, and control hardware, tests can be performed onsite at the customer’s integration facility in typically 3–4 days. MSI DFAT provides both equipment sales or rental and a DFAT‑as‑a‑service offering, delivering rapid, repeatable, and cost‑effective qualification across the globe.
Target Audience
Primary customers are aerospace manufacturers, satellite integrators, launch‑vehicle providers, and space agencies that need acoustic qualification of spacecraft, payloads, and related hardware.
