Claims

[Scope of utility model registration request]

A large-diameter measurement tunnel containing a rotating terrain model with a diameter larger than the width of the horizontal wind channel is provided in the horizontal wind channel of the wind tunnel, and the large-diameter measurement tunnel is partitioned into an air channel with the same width as the above-mentioned air channel and auxiliary air channels on both sides thereof. In a gas diffusion test wind tunnel having a partition wall, a movable shaft is supported slidably in the vertical direction on the side of the auxiliary air duct of the partition wall and has a roller pivotally attached to its lower end to roll on a terrain surface; A topographical model coordinate reading device comprising: a movement amount detector attached to the auxiliary air path side and detecting the amount of elevation of the movable shaft.
