Aeronautical Development Agency (ADA)

(a) Math models of the NLG ( for Linear & Non-linear equations of motion) along with the Computational Methods for their solutions.
(b) In-house Computer Codes (in MATLAB & FORTRAN) for dynamic analysis of the models.
(c) Detailed report containing Stability Boundaries, Phase portraits and LCO Amplitude variations with changes in the design parameters of the NLG ( with typical base line model & with LCA parameters).
(d) Recommendations to optimize the design parameters of NLG for improving its robustness to shimmy.
