Phase I Amount
$49,500
The development of a linear strut suspension system design utilizing compressible fluid is proposed to enhance the utility of the usmc lav-25. DTI will apply direct experience and proprietary knowledge gained in other successful applications of its compressible fluid suspensions technology to other military vehicles and heavy duty mining trucks. DTI will use silicone as the compressive media to integrate spring and damping functions into 8 individual wheel units, providing a lighter, simplified system through elimination of torsion bars, bulky single rate springs, separately mounted shock absorbers and other ancillary mounting pieces. The dti system will feature independent, adjustable, spring and damping rates for the widest range of vehicle weight carrying capacity possible while improving the ride characteristics and overall mission capability. The preliminary investigations will start with collection of all presently known data on the lav-25 including static and dynamic test measurements. DTI layout drawings and engineering load and damping curves will show packaging and performance capabilities. DTI computer generated calculations and simulations will provide data necessary to demonstrate the feasibility and desirability of the proposed system and potential variations.

The final development and prototype manufacture of the DTI system design utilizing compressible fluid is proposed to enhance the utility of USMC-LAV 25. DTI will apply direct experience and proprietary knowledge gained in other successful applications of its compressible fluid suspensions technology to other military vehicles and heavy duty mining trucks. DTI will luse silicone as the compressive media to integrate spring and suspension damping functions into 8 individual wheel units, providing a lighter, simplified system through elimination of torsion bars, bulky single rate springs, separately mounted shock absorbers and other ancillary mounting places. The DTI system will feature independent, adjustable fluid suspension for the widest range of vehicle-carrying capacity possible while improving the ride characteristics and overall missiion capability. Phase II activity begins with the reduction of the approved preliminary design to practice. This includes completion of detail design, calculation and finally, a production drawing package. Then DTI will manage the prototype manufacturing phase by providing assistance in the following: manufacturing, quality control, schedule compliance, and final assembly.
