Phoenix

Dr. John Pye is Group Vice President in charge of Exponent's Transportation group of practices. With a background in mechanical and aerospace engineering, Dr. Pye has expertise in issues pertaining to rapid prototyping, product design, instrumentation, fluid mechanics, structural analysis, and mil-standard testing. Dr. Pye has been the program manager for numerous rapid development efforts focused on adapting and integrating a range of high technology commercial components to the unique operational environment of the military customer as well as to extreme environment or high reliability commercial applications. Some of the programs he has led include the MARCbot IED inspection robot that was deployed in Iraq and Afghanistan, the RDISS networked surveillance system, and the Duracrete/Panama Ground Penetrating Radar system used in the hunt for buried explosive devices by various US and International customers. He has worked within the U.S. Army soldier system community as the test and evaluation lead during the development of the Land Warrior future soldier program, and as the lead engineer during the first phase of Objective Force Warrior. Dr. Pye is also the Office Director for Exponent’s 150 acre Test and Engineering Center located in Phoenix, AZ.

Prior to joining Exponent, Dr. Pye held a research position in the Aerospace Fluid Mechanics Lab at Stanford University, where he was responsible for the renovation and redesign of the Stanford Low-Speed wind tunnel as well as managing the Stanford experimental facilities of the Stanford/NASA Ames Joint Institute for Aeronautics and Astronautics. He was part of the technology development team for a holographic data-storage company and worked in the R&D department of the Orenda engine division of Hawker-Siddeley, Canada.

Project Experience

Nett Warrior — Lead engineer for the 2020 Architecture definition of the Nett Warrior program. Nett Warrior is the evolution of the Land Warrior, Objective Force Warrior, and Ground Soldier programs that leverage an ensemble of commercially derived wearable electronics to bring situational awareness and command and control capabilities to the dismounted soldier.

Supplementary Closure Device — Lead Engineer for the development of prototype downhole oilfield tool used to close off the flow of product in an emergency situation.

Duracrete — Lead engineer for the adaption of a commercial ground penetrating radar system and development of custom detection software for a deployed Route Proving and Clearance system for the US Army.

Duraplex — Lead engineer for a research and development program for an advanced multi-channel counter IED radar detection system.

Panama — Lead engineer of the PANAMA detection capability for the UK Ministry of Defence’s robotic Route Proving and Clearance system (Talisman).

Land Warrior — Contractor test lead for the Land Warrior 1.0 program. Land Warrior is a U.S. government program with the objectives of bringing advances in situational awareness, lethality, and survivability to the soldier through a networked collection of wearable digital devices.

Objective Force Warrior — Lead engineer for the Phase One Objective Force Warrior program. Objective Force Warrior (now Future Force Warrior) is a follow-on exploration of the Land Warrior capabilities, treating the soldier and all of his gear as a single system and examining opportunities for enhancement that the 'soldier-as-a-system' concept brings.

MARCbot IV — Program manager for the MARCbot IV development and production. The MARCbot is an IED (Improvised Explosive Device) inspection robot, of which ~1000 have been delivered and was used by soldiers in Iraq and Afghanistan.

RDISS — Program manager for the development and initial fielding of RDISS: Rapidly Deployed Integrated Surveillance System. RDISS is networked collection of surveillance assets that can be quickly installed in small, fixed sites. Approximately 300 systems have been delivered and are in use by soldiers in Iraq and Afghanistan.

MAVARC — Program manager for the development of the MAVARC micro-air vehicle. MAVARC is a man-portable, impact resistant, unmanned air vehicle that was developed with a PDA controller to explore the limits of portability and very simple interfaces for the dismounted soldier working with unmanned air vehicles. A prototype system was flown in Afghanistan in 2004.

Auto-Mortar — Program manager for the development of a robotic conversion kit for a captured-piston, multiple-launch, 51-mm mortar system.

Apple iMac — Participated in the structural analysis, failure mode analysis, load envelope determination, and performance evaluation of the articulating display for the original Apple iMac.

747 Cargo Conversion Analysis — Performed a detailed structural analysis of a retro-fit cargo door surround structure in a 747-100 aircraft. Non-linear finite element techniques were used to quantify structural failure loads.
