How can USD provide value-added engineering and services to complement an OEM's design team?
USD consists of two divisions which has an experienced talent pool with a wide range of capabilities. Within USD's 85,000 square feet of floor space you can find capital equipment for machining, environmental test chambers for screening and Orbital and Laser Welders for precision welding. Experienced machinists working with our talented engineering team, which has analog, digital and RF experience, allows USD to create a team of unique disciplines to support your upcoming project.
 
Can USD reverse engineer, repair and upgrade legacy systems?
USD has matched its production capability with a successful repair and upgrade business. We are one of a limited number of organizations designated as a U.S. Government Repair Facility operating under our Air Force repair facility code of EZ7112 and a Navy repair code of Q97469. Through the reverse engineering and manufacturing process, USD has been able to repair or modify many otherwise obsolete products or systems and provide solutions in the event of a Diminishing Manufacturing Sources (DMS).
 
Is USD interested is being a source for the repair/overhaul and supplier of new or build to print assemblies for the major defense suppliers (Lockheed Martin, Raytheon, General Dynamics, Northrop Grumman, etc…)?
USD is interested in the possibility of being a source for the repair/overhaul and supplier of factory new or build to print assemblies and subassemblies in support of mature systems that major suppliers do not wish to support for low quantity buys or repairs.
 
What programs has USD Military Sustainment Services division supported for repair, new builds and reverse engineering?
USD supports the following platforms:
A-10, A-6, A-7, E-2C, B-52, C-130, C-141, CH-46, E-3, F-4, F-5, F-14, F-15, F-16, F-18, Phalanx, P-3, T-37, T-38 and Tow Cobra.

Does USD have a form, fit and function replacement for the Honeywell GG1111 series Gyroscopes?
USD's 446 series rate integrating gyroscopes provide form, fit and function replacements for the Honeywell GG1111 Series click here for the 446 series brochure. For additional rate gyroscope or rate integrating gyroscope information contact sales@usdynamicscorp.com.
 
What is the difference between a Rate Gyro and an Integrating Gyro?
Rate Gyro:
A rate gyro is generally a single-degree-of-freedom gyro having primarily elastic restraint of the spin axis about the output axis. In this gyro an output signal is produced by precession of the gimbal, which is proportional to the angular rate of the case about the input axis.

Rate Integrating Gyro:
A rate integrating gyro is generally a single-degree-of-freedom gyro having primarily viscous restraint of the spin axis about the output axis. In this gyro an output signal is produced by precession of the gimbal, which is proportional to the integral of the angular rate of the case about the input axis.

Precession:
Precession is a rotation of the spin axis produced by a torque, T, applied about an axis mutually perpendicular to the spin axis and the axis of the resulting rotation. A constant precession rate, , is related to rotor angular momentum, H, and applied torque, T, by the equation T = H.
