I will perform 6 dof flight dynamics and stability analysis
About this Gig
I perform 6-DOF longitudinal and lateral-directional stability analysis, helping engineers, students, and UAV developers catch handling problems early using proven flight dynamics methods.
What you get:
- Eigenvalue computation and flight mode identification (short-period, phugoid, dutch roll, spiral)
- Damping ratio & natural frequency for each mode
- Handling qualities assessment against Level 1/2/3 criteria
- Stability margin / root locus plots
- Optional: stability augmentation system (SAS) design to fix poor damping
Background: I build 6-DOF flight dynamics models professionally, with hands-on experience validating stability derivatives against real flight-test data and designing damping-improvement systems.
What I need from you: Your aircraft/UAV's linearized state-space model, mass/geometry/derivative data, or flight-test logs whatever you have, I'll scope the analysis accordingly.
Send me your details and I'll confirm exactly what's achievable in your package tier.
FAQ
What format should I send my aircraft data in?
Any format works — a linearized state-space model (A/B matrices), a list of stability derivatives, or raw flight-test logs. If you're unsure what you have, just describe your aircraft and I'll tell you what's needed.
Do you need my full aircraft design, or just some numbers?
Just the numbers — mass, key geometry, and stability/control derivatives (or flight data I can extract them from). I don't need your full CAD model or proprietary design details.
What software do you use?
Python/MATLAB for the analysis — no Simulink dependency required, so turnaround is fast.
Can you also fix a stability problem, not just identify it?
Yes — that's the Premium package, which includes a stability augmentation system (SAS) design like a pitch damper.
Is this valid for fixed-wing only, or also multirotor/VTOL?
Primarily fixed-wing aircraft and UAVs. For multirotor-specific dynamics, message me first to confirm fit.
How is this different from a generic "aerospace consulting" gig?
I don't just discuss concepts — you get a specific, quantified deliverable: eigenvalues, damping ratios, and a written assessment against real handling-qualities standards, matching how this is done in actual flight-test programs.
