engg1Founded by aeronautical engineers with experience in both military and commercial aircraft, aeronautical engineering remains central to TDA’s business. Since its inception, TDA has worked extensively with the United States Navy’s (USN) aircraft structures division in support of USN F/A-18, F-14, E-2, P-3, S-3, C-2, C-130, EA-6B, H-60, H-53, VH-71, H-1, H-3, and V-22 aircraft and rotorcraft.

Areas of Aeronautical Engineering Expertise:

  • Structural design and analysis of aircraft structures
    • Military and Commercial Aircraft
    • Metal and Composite structures
    • Design Review
    • Stress Analysis – both Classical and Finite Element Analysis
  • Fatigue, damage tolerance, and risk assessment of aircraft structures (courses available for corporate training)
  • External loads analysis (derivation of aerodynamic loads, inertial loads, fatigue loads, and design loads – including the effects of aeroelasticity) and power-spectral density (PSD) analysis (courses available for corporate training)
  • Flight-test loads and flight parameter analysis
  • Aircraft fatigue monitoring systems
    • Flight Data Recorders
    • Log book data
    • Data quality control and data processing
  • Aircraft usage and environmental criteria derivation
  • Aircraft structural test support, including coupon, static and fatigue
    • Test planning and report preparation
    • Strain gage location determination
    • Test schedule preparation
  • Failure analysis
  • Commercial and military aircraft design criteria and specifications

TDA Utilizes the Following State-of-the-art Engineering Tools:

  • MSC Nastran/Patran for finite element modeling and analysis
  • ZAERO for aircraft external loads analysis
  • NASGRO, AFGROW, and FASTRAN for crack growth analysis
  • FAMS for fatigue life analysis
  • Matlab/Simulink
