This study was undertaken in MSFC's 14-Inch Trisonic Wind Tunnel to determine if rapid prototyping methods could be used in the design and manufacturing of high speed wind tunnel models in direct testing applications, and if these methods would reduce model design/fabrication time and cost while providing models of high enough fidelity to provide adequate aerodynamic data, and of sufficient strength to survive the test environment. Rapid prototyping methods utilized to construct wind tunnel models in a wing-body-tail configuration were: fused deposition method using both ABS plastic and PEEK as building materials, stereolithography using the photopolymer SL-5170, selective laser sintering using glass reinforced nylon, and laminated object manufacturing using plastic reinforced with glass and 'paper'. This study revealed good agreement between the SLA model, the metal model with an FDM-ABS nose, an SLA nose, and the metal model for most operating conditions, while the FDM-ABS data diverged at higher loading conditions. Data from the initial SLS model showed poor agreement due to problems in post-processing, resulting in a different configuration. A second SLS model was tested and showed relatively good agreement. It can be concluded that rapid prototyping models show promise in preliminary aerodynamic development studies at subsonic, transonic, and supersonic speeds. Springer, A. M.

Whether an airframe is a new design, modification of an existing design, or evaluation of a competing or foreign design, an accurate, high-confidence representation of the airframe aerodynamics is paramount to any low-risk design or evaluation effort. These aerodynamic estimates are used for vehicle and component sizing, performance estimates, and autopilot design and evaluation. The advent of new rapid prototyping manufacturing techniques and materials could provide a means to reduce the cost associated with the acquisition of a wind tunnel model (WTM), provided the data obtained with the rapid prototype model (RPM) were of sufficient fidelity to justify its use. The Johns Hopkins University Applied Physics Laboratory (JHU/APL) has developed a WTM design that consists of a steel strongback with rapid prototype plastic components attached to it to provide the overall vehicle configuration. In a test at the Lockheed Martin Missile and Fire Control%Dallas High-Speed Wind Tunnel (HSWT), this model (designated RPM-01) demonstrated acceptable data quality and test-to-test data repeatability with a geometrically similar steel and aluminum model. RPM-01 was built for approximately a quarter of the cost and a fraction of the time required of the all-metal high-fidelity model.
