| Description |
This paper presents about the development and wind tunnel evaluation of an SMA based smart trim tab for a typical 2
seater civil aircraft. SMA actuator was housed in the port side of the elevator for actuating the trim tab. Wind tunnel tests were
conducted on a full scale Horizontal Tail model with Elevator and Trim Tab at free stream speeds of 25, 35 & 45 m/sec and also
for a number of deflections of the elevator (30° up, 0° neutral & 25° down) and trim-tab 11° & 21° up and 15° & 31° down). To
measure the hinge moment experienced by the trim-tab at various test conditions, two miniaturized balances were designed and
fabricated. Gain scheduled proportional integral controller was developed to control the SMA actuated smart trim tab. It was
confirmed during the tests that the trim-tab could be controlled at the desired position against the aerodynamic loads acting on it
for the various test conditions.
