Angeles Crest Engineering LLC (ACE) develops and designs advanced mechanical, structural, thermal, and fluid systems for aerospace, defense, and civilian applications. We specialize in aerospace propulsion systems and components. Our offices are in Pasadena, CA. We use advanced analysis techniques and perform targeted testing to accelerate the design cycle and use integrated CAD tools to enable a seamless interface with the design database for manufacturing. We are committed to continual improvement of our engineering processes that are used for designing and developing mechanical, structural, thermal, and fluid systems. ACE designed, built, and operated a twelve-foot centrifuge for high g fluid dynamic testing. ACE  operated a materials laboratory for propellant compatibility testing and performed testing to develop databases for concentrated hydrogen peroxide and hydrazine materials compatibility.
