Landing Gear — Preliminary Stress Sizing

Preliminary FE model and initial stress sizing of a landing-gear assembly during pre-PDR layout. Captured ground-load distribution, pin/lug load transfer and design-driver identification ahead of detail design.

Preliminary Sizing

Key work

FE model of strut, trunnion and fittings consistent with the gear kinematics.
Drop and braking load-case sizing against material allowables.
Iterated stock sizes and fillet radii with the design team.
Identified fatigue-driving locations for downstream DaDT work.
