Hill Engineering solves complex structural problems inherent to fatigue and fracture critical systems. We have a special focus on residual stress engineering solutions that include unique residual stress measurement capabilities and damage tolerant design approaches. We have further developed a track record in the use of compressive residual stress treatments to solve aging and sustainment challenges. Our skills are useful in industries such as aircraft, power generation, ground vehicles, turbo-machinery, and petrochemicals. We founded the business on contracts with US Navy and Air Force aviation programs and have progressed through three stages of R&D awards, with residual stress applications for their premier fighter aircraft. We have diversified our work across organizations large and small - who turn to Hill Engineering for cutting edge and affordable engineering solutions. Recent clients are headlined by the US Navy and Air Force, Rolls-Royce, Pratt & Whitney, Boeing, Lockheed-Martin, Siemens Power Generation, General Electric, DynCorp, and Schilling Robotics - they want a range of solutions for structures, from nuclear power plants to aging - but still mission valuable - aircraft.
