19. Airship Dynamically Stable Response || Airship Nonlinear Dynamic Stability Analysis - 2024
Based on the comment shared by one of our users - thekapilcomedyshow380 (assuming name: Kapil). I have changed the thrust force from values [1, 1] to [4000N, 2000N]. The results are now stable.
A fact from reference - that the CG of an airship should be ahead of the CB and the typical range of the XG = [0.5m to 2.0m] and ZG = [1.0m to 6.0m].
After changing thrust forces and the value of XG = [1.0, 1.5, 1.7, 1.8]m. We got most stable results from the airship. Hence, proving the designed nonlinear system in Simulink is accurate and can give reasonable results for any airship.

18. Checking Dynamic Stability of Airship in Simulink | Airship Nonlinear Dynamic Stability Analysis
Просмотров 802 месяца назад
The natural response of the S-500 airship is registered from the nonlinear model. It is observed that the airship is dynamically unstable in pitch. The pitch angle increases over the time with damped oscillations. The change in oscillations and pitching motions is observed as the position of center of gravity is changed from negative (towards tail) to positive (towards nose). The change is in f...
