The J.A.R.I. Full-Scale Wind Tunnel 780336

Our institute, J.A.R I., has built a new wind tunnel to accommodate full-sized vehicles. Various newly developed ideas were incorporated in this facility, which, nearly 100 m long, is of Eiffel type with two test sections arranged lengthwise that can be used simultaneously and efficiently. Wind velocity ranges from 2.5 to 57 m/s in the first test section, which is 3 m (H)x4 m(W)x10 m(L). In the second test section, which is 5 m(H)x6 m(W)x13 m (L), the wind velocity ranges from 1 to 23 m/s. The facility enables a wide range of aerodynamic experiments to be conducted with 1/5 scale models up to full-sized passenger cars in the first test section, as well as with heavy duty trucks and buses in the second test section.
