"Army pushes forward with project to design lightweight maneuverable vehicle with soldier protection"
July 30, 2014


WARREN, Mich., 30 July 2014. U.S. Army combat vehicle and vetronics designers are moving forward with a project to design maneuverable and lightweight land vehicles that protect warfighters inside from explosive blast, crashes, and rollovers.

Officials of the Army Contracting Command in Warren, Mich., announced a $6.5 million contract Tuesday to Pratt & Miller Engineering in New Hudson, Mich., to complete the build, integration, and final testing and evaluation for the Occupant Centric Platform (OCP) Technology Enabled Capability Demonstrator (TECD) test asset with warfighter protection from improvised explosive devices (IEDs).

The OCP TECD seeks to identify, develop, and integrate technologies that will protect occupants of Army ground vehicles with IED protection from explosions, crashes, and rollovers while maintaining or improving the mobility of the vehicle while reducing the weight for that protection.

Electronic technologies involved in OCP TECD efforts include sensors, automatic fire extinguishers, systems integration, and test and measurement.

Pratt & Miller specializes in car racing, processes, and advanced technology for full-service engineering and low-volume vehicle manufacturing. The company has expertise in prototyping and manufacturing of wide range of lightweight tactical vehicles, vehicle subsystems, and occupant protection technologies.

The company has expertise in electronics, autonomous systems engineering, hybrid/electric systems, power train integration, thermal systems, concept creation and development, trade studies, and requirements management for applications in vehicle suspension, chassis, mobility analysis, lightweight systems, body systems, interior systems, blast analysis, occupant protection, and survivability systems engineering.

The OCP TECD addresses gaps in occupant protection; blast research, crash and rollover mitigation, vehicle interiors for protecting occupants, and ground vehicle exterior technologies.

The intent is to provide safe and affordable military ground vehicles for small units conducting patrol, convoy, and transport activities; conducting movement operations in support of unit mission; or vehicles collecting data or aiding wounded.

The OCP TECD program is overseeing the development and evolution of a new and innovative warfighter-centered vehicle design philosophy, Army officials say. OCP provides the means to design, develop, demonstrate, and document a new occupant centered Army ground vehicle design methodology that improves force protection by reducing casualties and mitigating Soldier injury due to underbody mine or improvised explosive device (IED) blast events including the subsequent crash and vehicle rollover that often accompanies the blast.

The program seeks to characterize military vehicles through test and evaluation and modeling and simulation; understand the occupant responses in blasts, rollover, and crash events; and identify commercially off-the-shelf (COTS) technologies that may reduce the probability of injury in these events.

The OCP TECD, it seeks to identify, develop, and integrate technologies that will protect occupants of ground vehicles from underbody threats while maintaining or improving the mobility of the vehicle system while reducing the weight for that protection.

On this contract Pratt & Miller will do the work in New Hudson, Mich., and should be finished by January 2016. For more information contact Pratt& Miller online at http://prattmiller.com, or the Army Contracting Command Warren at www.tacom.army.mil.

Army prototypes are always interesting, be neat to see this when they roll it out. The sketch already looks like something from a game.

That image doesn't actually seem to go with OCP. Pratt & Miller list it on their website as being associate withn a program called Demonstrator for Novel Design (DFND)

Demonstrator for Novel Design (DFND):
Pratt & Miller was contracted to develop innovative medium combat vehicle concepts for the Demonstrator for Novel Design (DFND) program. The objective of the DFND program was to identify novel medium combat vehicle concepts aimed at maximizing force protection, vehicle mobility, and vehicle survivability on a compressed timeline. The weight range was set at 40,000-60,000 lbs. to be carried on 8 wheels. The requirements were identified as a sub-set of the Marine Personnel Carrier (MPC) draft requirements. The force protection requirements consisted of minimizing acceleration into the vehicle from an underbelly blast. The mobility requirements were made up of acceleration, grade climbing, handling, ride, and obstacle events. The concepts were designed to accommodate a 3 man crew and 10 dismounts in a vehicle capable of swimming. Other requirements were used to make package space and weight claims during the concept development. Threshold and objective requirements were established and confirmed with the MPC Program Office Team and TARDEC subject matter experts (SMEs).

Through benchmarking, brainstorming, systems engineering, and extensive use of modeling and simulation, the DFND team generated multiple concepts and objective data characterizing the performance of these concepts. Using a holistic vehicle trade study, the performance of the concepts was compared to identify the best balance of the competing parameters such as mobility and force protection. In addition to the use of a motorsports organization structure, product development process, and trade study format, motorsports tools and technologies were applied to several component and system concepts. Motorsports influenced concepts included seating systems, power pack packaging, suspension commonality, swim system drive, and ease of service considerations. Since one of the objectives of the program was to develop novel concepts, innovation was included as a primary trade study category. Some of the innovative concepts utilized were:
• Dual engines
• Application of mass production light truck engine
• Autonomy enabled platform
• Water steering system
• Hydraulic steering
• Brakes outboard of wheel
• Floating suspension actuator
• Catenary hull shape
• Dual a-arm, wall mounted, blast attenuating seat
• Fully isolated, blast attenuating floor system
• Morphing suspension that increases track width
• Steerable, dual leading/trailing arm suspension design
• Electric drive system with hub motors at each wheel
• Silent mobility
• Clean hull bottom

From OCP, I'd expect something more like this:
