John W. Callahan

Vice President

  • Over 30 years of design engineering and structural analysis experience in the aerospace, electro-optic, and simulation industries for mechanical products including gas turbine engines, composite structures, aircraft simulators, optical mounts for high-precision measuring instruments, and commercial medical products.
  • Structural analysis experience on flight simulators and spacecraft flight and MGSE hardware including the International Space Station ELC, DARPA Falcon Hypersonic Cruise Vehicle, and Advanced Stirling Radioisotope Generator (ASRG) programs.
  • Test experience includes static and dynamic testing for the Advanced Stirling Radioisotope Generator (ASRG) including random and sine vibration. Dynamic analyses performed include forced limited random vibration, sine transient pulse, sine disturbance, and acoustic.
  • Responsible for supervising the design team as well as program manager on flight simulator upgrades including B-52, RC-135, KC-130R, and CH-53D, and CMHP including design of aluminum honeycomb composite structures.
  • Design experience using PTC Creo (Pro/ENGINEER), SolidWorks,  AutoCAD, and CADKEY computer aided design programs and structural analysis using NASTRAN Finite Element code and FEMAP model processor.
  • BSME from the University of Virginia (1987)
