Dan Stuewe
Engineer & garage tinkerer
Dan Stuewe supports M4’s numerous federal and commercial customers, utilizing his experience with structural dynamics in development of several software projects, including software designed to build and assemble finite element model and analysis decks for the company’s RapidFEM software as well as a tool to process and correct wind tunnel test data. Commercially, he has worked on comprehensive stress analyses of hydraulic and electro-mechanical mechanisms. Additionally, Dan has spent extensive time developing dynamic models of mechanisms for use in pre- and post-test analysis and loads development.
Prior to joining M4 Engineering, Dan worked at McDonnell Douglas Space Systems (which later merged with Boeing), validating structural dynamic analyses of the Titan IV launch vehicle. His work in structural dynamics continued as a member of the team that developed the Delta III launch vehicle. As a member of the Delta III team, he participated in several structural tests by deriving pre-test predictions and performing post-test model correlations. He also developed a number of new analyses that were required based on the unique design of the vehicle. He used the knowledge from the Delta III development to assist in the development of the Delta IV family of launch vehicles as well as to support the established Delta II vehicle.
In his free time, Dan enjoys spending time with his family, volunteering in his community and church, and making things with wood in his garage.
