Abstract : A plan is presented for adding a 12- x 15-foot V/STOL test section in the return leg of the 7- x 10-foot transonic wind tunnel at the David W. Taylor Naval Ship Research and Development Center (DTNSRDC). Features include (1) an inflatable bellmouth which is collapsible/removable to permit conversion from V/STOL to transonic operation on a quick turnaround basis and (2) provision for opening roof doors in the V/STOL section to permit low-speed operation in an alternate section 22 feet high by 15 feet wide.
