The USAF Stability and Control DATCOM (Data Compendium) was compiled between 1960 and 1978 by the McDonnell Douglas Corporation in conjunction with the engineers at the Flight Dynamics Laboratory at Wright-Patterson Air Force Base. DATCOM provides a systematic summary of methods for estimating basic stability and control derivatives. The book is intended to be used for preliminary design purposes before the acquisition of test data.

Trusted by a global customer base
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 to fix a pretension that was between the bolt yield and separation, and that minimized the fatigue cycles on the bolt.

The value of ESDU is that it helps us move much more quickly to the correct answer. On average, we have reduced the amount of time required to design aerodynamic surfaces by 50% compared to the traditional approach. The answers that we obtain using the ESDU methods also tend to be more accurate because they are based on a combination of theory and experimental data, rather than theory alone.

ESDU provides unique validated data. I spend up to 30% of my time trying to validate some of the data used by our engineers. ESDU saves more than the cost of an engineer.
