Analysis of a Nulling Yaw Probe ME 450: Computer Aided Engineering Analysis Instructor: Dr. Nema Group members: Billy Holland, Alan Koers, Allison Heying
Objectives • Determine if stress or displacement will negatively affect function of device • Study vertical position of motor • Study horizontal position of motor • Study probe when exposed to air flow
Introduction • Apparatus to observe pressure and flow angle of annular flow in turbine engine • 462 project added component to allow for flow yaw angle measurement • Main area of concern is support for motor
Track Housing Motor Support Probe Motor Rack Complete Assembly
Theoretical Background • Solid 92 (Tetrahedral Solid): 10 Nodes, 3-D Space, DOF: UX, UY, UZ • Is the WORKBENCH default element
Model Details: Sub Assembly • Element Type: SOLID92 • Elements: 2579 • Nodes: 10004
Model Details: Sub Assembly • Model grounded at mounting holes in tracks • Moments applied to motor support mounting holes
Model Details: Yaw Probe • Element Type: SOLID92 • Elements: 2964 • Nodes: 5859
Model Details: Yaw Probe • Model grounded at probe base • Pressure due to wind speed applied surface of probe
Impact Statement • Probe apparatus will be safe for users • Knowledge of flow angle and pressure in turbine engine will allow for improvements
Conclusions • Design will have no problems due to stress or deformation • Factor of safety is at least 40
