Royal Charter (ship) by some passengers, though not confirmed, that the master, Captain Thomas Taylor, was advised to put into Holyhead harbour for shelter. He decided to continue on to Liverpool however. Off Point Lynas the "Royal Charter" tried to pick up the Liverpool pilot, but the wind had now risen to Storm force 10 on the Beaufort scale and the rapidly rising sea made this impossible. During the night of 25/26 October the wind rose to Hurricane force 12 on the Beaufort Scale in what became known as the "Royal Charter gale". As the wind rose its direction changed from E to
Wind tunnel high Reynolds number, since it is not practical to obtain full scale Reynolds number by use of a full scale vehicle. V/STOL tunnels require large cross section area, but only small velocities. Since power varies with the cube of velocity, the power required for the operation is also less. An example of a V/STOL tunnel is the NASA Langley 14' x 22' tunnel. Aircraft have a tendency to go to spin when they stall. These tunnels are used to study that phenomenon. Automotive wind tunnels fall into two categories: Wunibald Kamm built the first full-scale wind tunnel for motor vehicles.
