• UMN to measure mAEWing1 actuator freeplay
  • Will likely leave mAEWing1 stiff for initial flights to gather aerodynamic data, then cut skin and foam to be flexible for flutter suppression and shape modification
  • Dave S sent a working paper on preliminary aerodynamic results. Need to estimate pitching moment from the body flaps during flight tests; this control surface is a large contributor to flutter suppression, but has very low pitching moment effectiveness (primarily contributes lift force)
  • Further analysis of Fenrir flight indicates that increasing the rigid body pitch damper gain could have excited the center-body flexibility. Updates to the aircraft design for mAEWing1 should remove this flexibility.
  • VT finished the mAEWing1 FEM model and will be verifying the model with UMN. VT also conducted some preliminary aero modeling for mAEWing1, which is being used to develop MDAO tools for the mAEWing2 design.
  • The mAEWing1 FEM model will be updated following Ground Vibration Testing.
