Aircraft's Dutch Roll Simulation

This app provides an interactive environment to simulate and visualize the Dutch roll motion of an aircraft using a linearized state-space m

The Dutch Roll Motion Simulator is a MATLAB App Designer-based tool designed to simulate the aircraft's Dutch roll mode — a coupled yaw and roll oscillation common in lateral-directional dynamics.🎯 Key Features:

• Input fields for key stability derivatives:
• Yβ,Yr,Nβ,NrY_{\beta}, Y_r, N_{\beta}, N_r
• Airspeed control (VV) to assess flight condition effects
• Time-domain simulation of the state-space model
• Real-time plotting of:
• Sideslip angle (β\beta) in radians
• Yaw rate (rr) in rad/s
• Initial condition-based simulation (default: β=5∘\beta = 5^\circ, r=0r = 0)

📊 Outputs:

• Time history of aircraft response to an initial sideslip perturbation
• Visual interpretation of damping and natural frequency behavior

📦 Technical Details:

• Uses MATLAB’s ss() and initial() functions for simulation
• No external dependencies or toolboxes required
• Built entirely in App Designer for user interactivity

🎓 Educational Use:

Ideal for aerospace engineering students, instructors, or flight dynamics enthusiasts to:

• Understand Dutch roll mechanics
• Investigate dynamic stability effects
• Visualize how aircraft respond to lateral disturbances

🔧 How to Use:

1. Launch the app (DutchRollApp.mlapp).
2. Enter aircraft-specific stability derivatives and airspeed.
3. Click "Run Simulation" to generate the response plot.
4. Observe the aircraft’s dynamic behavior in sideslip and yaw.
