Any aircraft structure will have a number of mechanical resonances arising from its mass and stiffness, including the stiffness of any joints. Those resonances can result in excessive vibration if they coincide with particular forcing frequencies associated with the aircraft, e.g. the main propeller blade passing frequency.

Cranfield Aerospace Solutions Ltd (CAeS) has extensive experience of performing experimental Ground Vibration Tests (GVTs) across all types of aircraft installations ranging from full aircraft surveys to the identification and mitigation of resonance frequencies for helicopter installed equipment.

CAeS has a wide experience and long history of successfully conducting work of this kind. We are experienced in working with aerospace contractors, working to tight schedules and responding to urgent requirements. We are expert at conducting data gathering trials, installing bespoke instrumentation systems and in carrying out the necessary signal processing.

We offer comprehensive analysis and reports describing trials and their results in detail, giving confidence that we can confidently offer a compliant, low risk, efficient and cost effective service.

CAeS operates an ISO:9001 Quality Management System and is a DAOS Approved Organisation.
