Proven Engineering and Manufacturing Methodologies

Strength in Engineering Development, Design, Testing and Manufacturing


Engineering and Design
The FMH Aerospace team manages the entire engineering and design process, from development to manufacturing introduction. We begin by working closely with our customer to determine product and performance requirements, define specifications, and develop technical proposals to design or co-design each product. We then analyze materials selection and testing, prepare stress analysis, compile test procedures, and perform failure analysis, to create complete tooling and testing rig designs to ensure production meets or exceeds customer specifications.
FMH Aerospace is known for being very customer-focused and responsive, with a flexibility and willingness to experiment with designs, materials and manufacturing processes to achieve the best possible solutions for our customers. In most cases, we develop prototypes to validate product performance prior to manufacture. We are very disciplined around specification control throughout the design and development process. Our unique testing and analysis tools and methods allow for optimized designs and products, with all tooling and test rigs designed and fabricated in-house for speed and precision.
The FMH Aerospace team has deep knowledge of flexible bellows joints performance, refined over 67 years of developing and manufacturing bellows and joints for a wide variety of demanding applications. We are experts at designing for performance requirements within each customer’s strictly defined envelope of space where a ducting system or bellows component needs to fit. Our customers rely on our experience and expertise to design and manufacture bellows and other components to their stringent requirements.
Our technical strengths include bellows design; application specific assemblies optimizing weld joints, flex joints and contour; weld joint designs tailored to facilitate welding speed and quality; and braid design, using our in-house custom-built analytical tool. Our engineering team uses many design tools, including Catia, Pro-E, Solidworks, Iges, and CAEPipe; and many analytical tools, including Algor, Nastran, and NASA Flow Induced Vibration, as well as programs developed specifically by FMH Aerospace to analyze the performance of bellows, braids, and weight, Delta P, and flange loads. All Acceptance Test Plans and Qualification Plans are developed in-house.

FMH Aerospace provides depth, strength and scale in manufacturing that is unparalleled in the aerospace industry. We are highly vertically integrated and strive to achieve world-class standards in all of our manufacturing processes. Our precision forming methods establish a strong foundation for developing reliable manufacturing steps to ensure our finished products meet or exceed our customers’ expectations.
The FMH Aerospace comprehensive advanced machining center includes 3-, 4- and 5-axis CNC latches and mills. Our formed and welded bellows production includes in-house tube manufacturing to radiographic standards as well as a number of in-house custom-developed bellows forming systems for manufacturing bellows with exceptional performance. Our strength in braiding design is complemented by our own braiding production capabilities. Our tube bending department uses a number of different technologies and techniques for achieving the desired results. We weld to high standards that meet Class A Aluminum at X-ray levels, and also use a wide range of welding methods to accommodate specific customer requirements. FMH Aerospace has the capability to assemble products and systems from simple to highly complex, and ranging in size from small to as large as 50 feet.

The FMH Aerospace product testing team ensures that our manufactured components meet or exceed customer specifications with a variety of performance-specific testing procedures, including proof pressure, burst pressure, pressure impulse, pressure drop, helium leak, loads capacity, cycle fatigue, vibration, shock, endurance, thermal, cryogenic, bending moment, X-ray, and dye penetrant testing.  Our strict adherence to this extensive testing process was originally developed and refined over our years of designing and manufacturing mission critical components with no redundancy for the space industry. We continue to test every product we make with diligence and dedication to delivering exceptional quality to our customers.
