A wind-tunnel to provide data from manoeuvring aircraft is developed. The rig is a horizontal pendulum type that is capable of large amplitude motions in 5 degrees of freedom. This enables a large set of conventional and extreme aircraft manoeuvres to be performed in the controlled environment of a wind tunnel. A mixed dierential-algeb raic mathematical model, with terms accounting for friction in the gimbals is developed. A pilot has been fabricated and a preliminary experimental programme undertaken. To illustrate some of the capabilities of the rig, a selection of 1,2,3 and 4 degree-of-freedom experimental results is given. The procedure for the tting of the friction model is presented and a time-domain based lter-error method is used to t a linear aerodynamic model to the longitudinal cases.
