  • Thermal Expansion Measurements on Operating Automobile Engines
    of the crankshaft bearings and rear main seal. This development has introduced a potential problem area that must be analyzed. As engines go through heating and cooling cycles it is essential that the engine block and oil pan expand and contract at nearly the same rate. If not, stresses can be introduced

  • Ultrasonic Cleaning of Aircraft Components
    Many applications exist in the aircraft industry that can benefit from ultrasonic cleaning. Typical applications include brake parts, generator components, actuators, shuttle valves, filters, engine blades and vanes, aircraft wheels and bearings. Turbine blades and nozzle vanes from jet engines
  • Measuring Machining Imperfections and Runout in Automobile Wheel Spindles
    to measure wafer thickness, total thickness variation (TTV), bow, warp and flatness of semi-insulating and semiconducting materials. MTII’s Aviation Balancing Instruments group provides state-of-the-art portable balancing and vibration analysis systems for turboprop and jet aircraft engines. Whether
  • Slick as a whistle, hard as a rock
    Nibron, a coating of nickel, thallium, and boron, improves wear and hardness on aerospace and automotive components. Several military jets, including the Air Force's new fighter, the F-22 Raptor, have engine components coated with Nibron to reduce wear. This chart shows that Nibron is harder than
