Integrated engineering
More than isolated analysis
LIKUA can take responsibility for a defined engineering problem: requirements interpretation, concept development, design trades, physics-based modeling, review, test-data reduction and validated iteration. Analysis is used to support design decisions rather than treated as the final product.

Trajectory Analysis & Optimization
Trajectory modeling, range and sensitivity studies, constrained optimization and multidisciplinary design trades.

Integrated solid rocket motor engineering services
LIKUA supports motor development from the initial technical brief through engineering assessment and design review.
