Vibration Test on a Nomad N24A Aircraft Fitted with One Modified Aileron

Abstract : Following doubt raised about the loads experienced on the flap and aileron of Nomad aircraft in flight, a flight test program was formulated to measure these loads. An aileron fitted with strain gauges and the associated wiring was installed on a Nomad N24A aircraft but this rendered the aircraft non-standard. To verify the aeroelastic stability of the aircraft when fitted with the instrumented aileron, a flight flutter trial was proposed. An abbreviated Ground Vibration Test (GVT) was conducted on the aircraft to support the flutter trial, and this report describes the GVT and presents the results.
