Talk To Us
At SDA, we primarily provide engineering analysis services. Our focus has been aerospace primary structure using composite materials, but we also provide general stress analysis for a variety of industries. Because of this, our project experience is diverse. Many UAS and space industry products were developed with our expertise.
Our analyses are rooted in hand analysis and backed by complete models. When necessary, highly detailed models are constructed of specified areas. We have collaborated with an assortment of companies in the aerospace and defense industries. SDA has previously consulted in project design, materials choice, analysis, manufacturing, and testing of aerospace structures. We can tailor your design by cost, strength, weight or any other metric. Our engineers are more than proficient in the use of many relevant engineering software tools to help you achieve your goals, and can turn raw analyses into polished, professional reports with quick turn-around.
Strategic use of composites can deliver greater control of your final product’s strength and stiffness. This necessitates a unique engineering perspective due to the high degree of directionality inherent to composites. Many companies tend to shy away from composites for this very reason. Let us leverage our expansive knowledge of composite engineering for your project.
SDA has been designing and analyzing composite structures since it’s inception. Composites are our passion and we enjoy developing new and efficient composite structures. Our experience includes large composite aircraft structures including the B-2 Bomber and F-22 Fighter programs, several space programs, and multiple unmanned air vehicle structures. One of own most renowned composites projects was the NASA commissioned Composite Crew Module. Working as part of a team constructed by the NESC, SDA played a vital role in the design and anlaysis of this complex structure.
