Project Overview:
Development of the ARES VTOL TX Transformer

Customer:
Piasecki Aircraft Corp. and Lockheed Martin (end user DARPA)

Services Performed:
Provided design development and structural analysis of the center wing, pylon, tail and spindles of the TX Transformer.

Structural Analysis:

• Created a detailed Finite Element (FE) Model of the wing structure
• Modified the FE Model as necessary when design changed
• Provided section cuts and free-body diagrams of flight events as required
• Performed detailed structural analysis of the:
  • Center Spar
  • Duct Tilt Assembly
  • Fairing Fittings
  • Inner and Outer Ribs
  • Landing Gear
  • Leading Edge
  • Spindle
  • Pylon/Pylon fittings
• Performed buckling analysis to identify structural deficiencies
• Provided final FE Model and analysis files to Piasecki

Engineering Design:

• Performed design studies and weight reduction effort
• Modified the center wing tail structure to satisfy deflection requirements
• Modified the spindle to satisfy deflection requirements
• Supported various design changes specified by Piasecki
• Participated in weekly teleconferences and on-site support as necessary at Piasecki in Essington, PA
