It uses nitrogen gas, at high pressure, to cool the air which allows flight aerodynamics to be duplicated in small scale. The cross section of the tunnel is high and wide. Unlike full scale wind tunnels, the NTF can adjust airflow to match any model size down to 1/50th scale. The facility can operate liquid nitrogen is sprayed into the circuit or at ambient air temperature.〔http://gftd.larc.nasa.gov/references/NTF_factsheet.pdf〕 The facility has tested aircraft such as the Boeing 777, Boeing 767, Space Shuttle as well as blended wing designs such as the B-2 bomber, A-6 Intruder, F-18 Hornet. 〔(National Transonic Facility - NasaCRgis )〕 File:NTF STS wind tunnel model.jpg|Space Shuttle model used in testing at the NTF File:NTF Nitrogen input.jpg|Instrumentation penetration File:2001 Boeing 777 Test NTF.jpg|Boeing 777 model under test ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「National Transonic Facility (Hampton, Virginia)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
