This paper presents the experimental results of a wind tunnel test of a morphing trailing edge device known as the Fish Bone Active Camber (FishBAC) concept. This design uses a biologically-inspired compliant structure to change the amount of camber in the aerofoil. This paper will focus on experimental validation of the lift and drag properties of a FishBAC design for fixed wing applications. This will be established through a wind tunnel test run at various angles of attacks and camber deformations. A 900 mm span model of a 25% chord FishBAC was attached to a NACA 2510 wing section with a chord of 600 mm and tested in the 1.1 m diameter open jet wind tunnel at the University of Bristol. Endplates were used to encourage 2D flow over the wing and an AMTI OR6-7 force balance was used to measure the forces and moments acting on the wing. The FishBAC device shows excellent lift control authority with a Cl range of 0.86 achievable over a wide range of angles of attack through active variation of camber.
