Over 25 years experience in the space and aerospace industries (working on launchers, satellites, aircraft, rotorcraft and drones) covering all aspects of static and dynamic structural design, analysis, and testing. I have worked at various technical levels from stress engineer/analyst up to stress lead and technical management positions. I have been involved at every project stage; from conceptual design and sales support through to ground and flight testing, certification and in-service support.
I am knowledgeable in all aspects of the use of metallic and composites for space and aerospace applications, the definition and development of tools and methods, and the application of classical hand calculations and linear and non-linear Finite Element (FE) analysis to lightweight structures.
I have expert experience of a wide range FE software (Nastran, Patran, FEMAP, Hypermesh), CAD software (CATIA, Inventor, Solidworks), MathCad, Office, and bespoke software including ISAMI.
