Can anyone give advice on CFD validation cases for airships? We are developing airships about 50 meters long. CFD simulation is heavily used for providing data for performance and control/stability analysis.
Yes, I know some NACA report, I am actually asking for full vehicle aerodynamic data. Good wind tunnel data with hull only, hull+fins,hull+fins+gondola, hull+fins,hull+fins+gondola+propulsion. It is supposed difficult to get all the data. But even partial data will benefit my work.
Hi!: it doesn't answer your question, but you may like having a look at the attached document from 1904, that describes an original approach to the desing of airships, it has handwritten comments from author, sorry, it's in Spanish, and belonged to the library of relatives to Leonardo Torres-Quevedo, an Spanish engineer, known from his: 'Chessplaying automat', and a cable cabin transport installed downstream from Niagara Falls. Good season, + salut
