Engineering Sciences Data Unit (ESDU)
Engineering decisions demand more than theory. That’s why ESDU offers validated engineering design methods and data, trusted for 80+ years. It transforms deep engineering science into practical, defensible guidance your engineers can apply with confidence.
From concept to certification, ESDU helps teams reduce uncertainty, shorten design cycles, and prove decisions with rigor.
ESDU goes beyond textbooks, handbooks, and academic papers. It delivers rigorously validated engineering methods, data, and software derived from a global expert committee process, grounded in both theory and experimental evidence.
See how engineers design safer systems, accelerate analysis, and eliminate rework using engineering intelligence built for mission- and safety-critical applications.
Built on rigor. Proven by experts.
ESDU engineers develop each Data Item using established theory, experimental data, and real-world engineering practice.
Technical committees of leading industry, academic, and government experts rigorously review, test, and validate every Data Item throughout development. This ensures accuracy, applicability, and engineering relevance.
Validated Data Items are delivered through a clear, efficient interface with explanations, derivations, software tools, examples, graphs, and tables so engineers can apply them directly to real design problems.
Your ESDU subscription includes everything engineers need to design with confidence.

Engineering and academic professionals use ESDU to:
Chief Engineer
Safran Group
“If the right senior engineer isn’t on the team, the problem goes around several loops of analysis. I just asked the engineers to refer to the ESDU method, and that minimized fatigue cycles while staying within yield limits.”
Head of Advanced Aerodynamic Design
Cessna Aircraft
“We reduced the time required to design aerodynamic surfaces by 50%. The answers are more accurate because ESDU combines theory with experimental data.”
ESDU Data Items are endorsed by:
Ensuring every method reflects a true consensus of expert engineering judgment.
