    Mount Design and Construction 

    The LORD MAA Series utilizes a unique sandwich-style construction specifically engineered for aerospace applications. At its core is a precisely bonded elastomeric element that provides controlled stiffness and damping characteristics.

    Key design elements include:

    • Fully bonded construction for predictable, reliable performance
    • Stainless steel and aluminum components for minimal weight
    • Careful material selection to meet aerospace environmental requirements
    • Available in BTR® silicone for -65°F to +300°F operation or BTR® II silicone for -40°F to +300°F


    The combination of materials and construction creates an isolator that maintains effectiveness across a broad range of conditions while keeping size and weight to a minimum.

    Performance Characteristics 

    The MAA Series offers consistent, predictable performance across its operating range. Understanding these characteristics is essential for proper mount selection and application.

    Key performance attributes:

    • Load ratings from 0.5 to 1.5 lbs per mount
    • Natural frequencies from 27-63 Hz depending on model
    • Dynamic spring rates optimized for lightweight components
    • Excellent damping characteristics to control resonant amplification
    • Maintains performance across full temperature range


    Each model is engineered to provide optimal isolation for specific load ranges while maintaining a compact form factor.

    Applications 

    The LORD MAA Series is designed specifically for aerospace and defense applications requiring isolation of lightweight, sensitive equipment. Their compact size makes them ideal for space-constrained installations.

    Common applications include:

    • Avionics equipment isolation: Protects sensitive aircraft electronics from vibration and shock transmitted through the airframe during flight operations and landing.
    • Inertial guidance systems: Isolates precision gyroscopes and accelerometers from external disturbances to maintain accuracy of navigation and stabilization systems.
    • Electronic control units: Shields mission-critical digital control systems from mechanical interference that could disrupt processing and cause system errors.
    • Navigation equipment: Provides isolation for GPS receivers, radar systems, and other navigation hardware to ensure reliable operation in high-vibration environments.
    • Communications hardware: Protects radio frequency equipment and signal processing components from vibration that could degrade transmission quality or damage sensitive circuits.
    • Sensor packages: Isolates environmental, tactical, and diagnostic sensors from mechanical noise that could corrupt data collection and reduce measurement accuracy.


    The mounts excel in applications where minimizing size and weight is critical while maintaining isolation effectiveness.
