| Abstract | This report describes the modifications required to adapt the wake survey gear to CPF model IOT-691 for Project #422104 (CPF Stern Flaps). Modifications include lengthening of the vertical and horizontal posts, increasing the diameter of the vertical post to maintain the stiffness of the original configuration, and fabrication of a new stiffer table bracket. New farings were also designed to accommodate the increased dimensions of the other new components. The stationary foil was also replaced with a new self-aligning foil in an attempt to reduce unwanted lift due to improper alignment. Stiffness tests were performed on the wake survey gear. The results and implications of the stiffness experiments are also discussed. |
