Why the airship went down apparently still worries people, including aeronautical engineer Jem Stansfield, who has built three scale models to test the various theories and find the likely cause.
Three scale models were used and detailed air water measurements (void fraction, bubble count rate, bubble sizes) were performed systematically for identical inflow Froude numbers.
The impacts of Reynolds number effect on the distribution of the surface pressure and peak of pressure wave along the train, and the pressure waveform were also studied through numerical simulation on three scaled model trains (full scale, 1/8, 1/20, and 1/32 scaled).
Two scale model horizontal-axis TSTs were manufactured and deployed in a laboratory flume (11 m long, 1.6 m wide and 0.6 m deep) at different flow speeds and heights above the bed.
In case of different types of FRP composites, providing equivalent confinement modulus (lateral stiffness), five models are employed to find the FRP-confined concrete stress strain relationship of three scale-model circular columns.
The investigations involve three scaled models: columns with box cross-sections, columns with rectangular cross-sections, and a 2D frame.
It is important to note that, direct comparison between production time and measurement might be limited because the three scaled models were produced using different devices and materials.
"I bought two massive posters illustrating Rolls and Bentley cars through the years for a mere £5 (about $8), five scale models for £12 ($19) each and an antique, polished-silver hubcap with the Rolls-Royce logo for a pound ($1.60).
Six scale models of these arch-roof buildings were tested, with five types of canopies attached.
Wind tunnel simulations were performed to investigate flow distortion around two scale models of the Tower.
