Abstract

Response of airship owing to deflection angle of elevator, rudder and vectored thrust during trimmed equilibrium flight can be computed by solving the airship equations of motion. In this study, the linearised decoupled airship equations of motion were used and the solution was computed with the aid of Matlab software. This paper shows a case study done by applying the physical data of a designed airship called ‘UTHM’s Airship’ in the equations of motion and solved it in order to understand and analyze the response of the designed airship. For ‘UTHM’s Airship’, the longitudinal response of elevator and thrust vectorization has relatively low longitudinal control power and a rather sluggish response characteristic. Meanwhile the lateral response of rudder demonstrates a relatively high rudder control power and quicker lateral response compared to longitudinal response. The results had successfully given an initial insight of the ‘UTHM’s Airship’ response and dynamic stability.
