Environmental Test Support

Representative testing with hardware protection in view

LaFontaine Engineering supports aerospace environmental testing from planning through execution and post-test correlation. We combine analytical predictions with practical test engineering to address program requirements, representative loading, and over-test risk.

​​

Inputs we work with

Program and customer requirements, structural models, Mass Acceleration Curves (MACs), predicted responses, and test-article characteristics.

​

Pre-test analysis and planning

Define objectives, environments, success criteria, predicted responses, margins, and critical response locations. Outputs can include defensible test levels, notching strategies, and force-limiting thresholds that balance hardware protection with required input energy and frequency content.

​

Instrumentation and execution

• Accelerometer, force-sensor, and acoustic-sensor selection

• Sensor quantities and locations for critical structural and acoustic responses

• Data-acquisition parameters and control-channel definitions

• Notching and force-limiting strategies for sine and random-vibration tests

• Technical support and data review during execution

​

Supported test types

• Sine burst for quasi-static load requirements

• Sine vibration for modal characterization, low-frequency loads verification, and workmanship screening

• Random vibration for launch and ascent dynamic environments

• Acoustic testing, including chamber testing and response monitoring, for liftoff and high-intensity environments

​​

Post-test assessment and deliverables

Measured responses are assessed against predictions and used for model correlation. Flight or qualification environments are updated as required by the findings and program scope.
