Ducted Fan UAV Modeling and Simulation in Preliminary Design
TL;DR: AVID OAV as mentioned in this paper is a design and modeling software tool for ducted fan vehicles that is capable of modeling the performance and flight dynamics during the conceptual and preliminary phases of vehicle design.
Journal ArticleDOI
Conceptual Design Studies of a Strut-Braced Wing Transonic Transport
John F. Gundlach,Philippe-Andre Tetrault,Frank H. Gern,Amir H. Nagshineh-Pour,Andy Ko,Joseph A. Schetz,William H. Mason,Rakesh K. Kapania,Bernard Grossman,Raphael T. Haftka +9 more
TL;DR: In this paper, a strut-braced wing (SBW) is proposed for transonic airliner designs, which uses a strut for wing-bending load alleviation, allowing increased aspect ratio and reduced wing thickness to increase the lift to drag ratio.
Journal ArticleDOI
Multidisciplinary design optimization of blended-wing-body transport aircraft with distributed propulsion
Leifur Leifsson,Leifur Leifsson,Andy Ko,William H. Mason,Joseph A. Schetz,Bernard Grossman,Raphael T. Haftka +6 more
TL;DR: In this paper, the authors investigated the effects of using a small number of large engines with a moderate number of small engines and ducting part of the engine exhaust to exit out along the trailing edge of the wing.
