AD Engineering applies first-principles engineering to complex problems spanning physics, testing, manufacturing, operations, and acquisition.
We reduce technical uncertainty, develop credible engineering concepts, and deliver decision-ready results—from research lab to flightline to orbit.
Every engineering challenge is different. Our process is not driven by software or buzzwords—it is driven by governing physics, operational understanding, and disciplined engineering judgment.
We identify the governing variables before building complex models. Understanding the physics prevents solving the wrong engineering problem.
Technical performance alone is insufficient. Every concept is evaluated against manufacturing, testing, operations, sustainment, and transition.
Large multidisciplinary problems are reduced into manageable engineering decisions while preserving the important physics.
The objective is not a prettier simulation. The objective is a better engineering decision.
These concepts are not marketing illustrations. They are examples of engineering ideas developed from governing physics, operational constraints, and practical implementation considerations.
Develop a non-explosive approach for defeating small unmanned aircraft while reducing collateral effects and preserving operational flexibility.
Develop a passive spacecraft protection concept for orbital debris environments while balancing mass, launch constraints, survivability, and practical integration.
