Aerospace Engineering s-duct inlet design aircraft design A design approach and performance analysis of a custom s-duct inlet is presented for a subsonic delta-wing unmanned aerial vehicle. The aircraft was designed, built at scale, and tested in a subsonic wind tunnel to obtain lift and drag characteristics. Lift and drag characteristics along with aircraft design requirements were used to determine an appropriate embedded jet engine for the scaled model. Important geometric parameters of the s-duct inlet consisted of a length-to-engine diameter ratio of 5.0, an offset-to-length ratio of 0.30, and an area ratio of 1.40. A review of fundamental concepts and the design process is presented to provide a foundation for future design iterations. Computational fluid dynamics software was used to analyze the inlet design performance in comparison to the well-documented RAE-M2129 inlet. Pressure recovery and circumferential/radial total pressure distortion were used to analyze inlet performance at zero incidence angle. Performance was also evaluated at an incidence angle of 21° to simulate a maximum rate of climb condition. Results for the inlet at zero incidence angle demonstrated a 1.12% decrease in pressure recovery compared to the RAE-M2129 inlet. Circumferential distortion intensity results were comparable between the two inlet geometries. The design inlet results showed larger distortion extent elements mainly due to flow separation from the second turn. Future experimental and computational work is proposed to further improve the inlet design. 2020-09-29 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1587489868259034 http://rave.ohiolink.edu/etdc/view?acc_num=osu1587489868259034 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
