Schematic of Eiffel type open wind tunnel[edit]

This tunnel is not an Eiffel type wind tunnel : 1. the test section is closed, not open (see the Eiffel tunnel view). Because an Eiffel tunnel is generally built inside a closed facility it can be described as a quasi return type tunnel, because the facility walls are in fact the return circuit. Correct legend would be "Schematic of an open wind tunnel". Plxdesi march 2013 — Preceding unsigned comment added by 89.3.150.181 (talk) 16:24, 26 March 2013 (UTC)[reply]
