A wind tunnel model of an aircraft, representing only the rolling motion, is(adsbygoogle = window.adsbygoogle || []).push({});

constructed using two small lifting surfaces mounted in the horizontal (i.e. x –

y) plane symmetrically on anaxi-symmetric body. The body houses a set of ball

bearings, which permit the complete model to roll about x – axis freely. Further,

the right lifting surface (pointing towards positive y axis) is given an initial

incidence of -3o with respect of the longitudinal axis of the body and similarly,

the left lifting surface (pointing towards negative y axis) is given an initial

incidence of +3o with respect of the longitudinal axis of the body. The wings

have 5 cm chord, 30 cm span (for each half part) and are made of Aluminium.

Generate the mathematical model of the above wind tunnel model in terms of

the roll moment as the disturbance and roll attitude as the output from the

system.
