| Abstract: |
The development of lighter and more efficient transport aircraft has led to an increased focus on gust load alleviation. A recent consideration in aircraft design is to use hinged wing tip devices to increase the aspect ratio, improving aircraft performance. Furthermore, experimental tests have proven the ability of passive hinged wing tips to provide additional gust load alleviation. This work introduces a brushed DC motor in the hinge for the control of wing tip rotation, and to improve gust load alleviation and manoeuvres via PD control. A light wing tip was designed that can be free-hinged or actively controlled with the motor, as well as the motor configuration also providing a fixed wing tip option. Experiments have been performed in the wind tunnel and the results will be presented. These tests include responses to 1 – cosine and harmonic gusts for all wing tip cases, with the aim of reducing the root bending moment due to the applied gusts. Additionally, non-zero angles of attack at the root to replicate take-off conditions, and using different starting fold angles, known as coast angles, of the wing tip are considered to determine the effect on the root loads, again in the presence of gusts. |
