The Multi-User System for Earth Sensing (MUSES), currently being developed by Teledyne Brown Engineering, is a platform which will be located externally on the ISS and is capable of hosting up to four Earth-observing instruments simultaneously. Data from the instruments will be used for a variety of commercial, scientific, and humanitarian applications.

Structural Analysis - Corporate Experience

  • Structural analysis on a Teledyne Brown Engineering, Inc. subcontract for a United States Special Operations Command (USSOCOM) asset.
  • Structural analysis on a Teledyne Brown Engineering, Inc. subcontract for the NASA National Payloads Office Multiple User System for Earth Sensing (MUSES).  Tasks included structural analysis and documentation for the DFMR (Design for Minimum Risk) Matrix and verification report.
  • Structural analysis on a Teledyne Brown Engineering, Inc. subcontract in support of a commercial contract proposal for the design and analysis of structural supports for a large chemical waste processing system.

Medium Range Target (MRT) Simulator

medium-range-target-simulatorThe MRT Simulator was designed and built to provide a reconfigurable test mass for proof loading the 45 foot Transporter/ Erector (T/E).  It includes four major cylindrical segments designed to replicate the mass and center of gravity of a 125% weight forty nine foot long Medium Range Target (MRT). Each segment is constructed of  40 inch diameter schedule steel pipe with bolted flanges welded to either end.  Two of the segments are filled with concrete to appropriate levels which match CG requirements.  The aft short segment includes a beveled flange at its aft end which matches the contours of the MRT V-band flange for launch stand hold-down.  The mass simulator has also been used as a Kinetic Energy Interceptor proof mass using two of the concrete filled segments with the aft hold-down segment.

Modernized White Phosphorus Facility Munitions Fill Sys.

Analyses were performed to verify the capability of the White Phosphorous Facility with Access Platforms to withstand the specification seismic excitation without permanent deformation. The primary goal of this analysis was to define seismically qualified anchorage systems for the Process Facility/Access Platform System.

Analyses were also performed to verify the structural integrity of the Fill Machine Access Platforms and Railings in accordance with OSHA requirements.


Straddle Carrier Ramp Feasibility Study

The straddle carrier ramp was designed to extend the vertical hoist capability of the straddle carrier shown above to dock height.  The air pallet platform incorporated scissor lifts to raise cargo to the desired dock height. The intended purpose was to load C4 missile stages into a storage magazine.

M747 Heavy Equipment Trailer Kingpin Modification

The M747 Heavy Equipment Trailer was originally designed with a 3.5 inch SAE kingpin interfacing with a heavy duty fifth wheel at a 61 inch height.  A special spacer incorporating a 2.5 inch commercial truck kingpin at the lower commercial fifth wheel height was added to the trailer.  Extensive analysis of this design was performed to verify the integrity of the new design.

Lance Target Missile System (LTMS) Ramp

Analysis was performed to verify that the assembly will withstand the loads induced during construction, handling, transportation and launch. The LTMS Ramp was designed to provide a 15 degree increase in elevation for Lance Missile launches.  The system is shown with a missile erected to a 70 degree launch elevation.


Foreign Missile Asset Safe Move Fixture

This fixture is mounted on a 3-axle ISO mount trailer. The fixture was designed to transport FMAs safely utilizing the native cradles originally designed to carry the FMAs on triple carriers.

CMS Recovery Trailer

The purpose of the CMS Recovery Trailers is to transport spent or live C4 missiles following recovery from an accident.  Existing disposal chocks were used with fore/aft restraint fixtures.  The entire system including the trailer was analyzed to verify structural integrity.

White Motor Dolly with Castor IVB

The cradles on the White Motor Dolly were re-designed to simplify the manufacturing process. Stress and buckling analyses were performed to verify the structural integrity of new design. This dolly was configured for transporting Castor IVB Missiles.
