中文摘要 | 穿音速風洞實驗為模擬飛行器在穿音速流場各種狀況之最佳工具,但目前在國內 穿音速風洞只有少數機座,對於穿音速流場實驗之研究仍屬陌生,在航空工業不斷求新、求 快的今天,加強對於穿(超)音速風洞實驗,實在有其必要。本研究的主旨為探討下吹式穿 音速風洞之設計,其主要的內容包括風洞本體之設計、數據擷取系統之建立及風洞的校驗等 工作。 |
英文摘要 | The purpose of this paper is to design a blow-down type transonic wind tunnel. The work terms include wind tunnel mechanical design, data acquisition system setup, and flow field calibrations. In the mechanical design, which include those of the high pressure air tank, the shot-off valve, pressure regulator valve, wide angle diffuser, settling chamber, contraction section, nozzle blocks, test section, model support, diffuser, and silencer. the arrnagement of data acquisition system primarily considers the current limited budget constraint and the expansibility in the future. In the flow field calibrations, which include hot-wire, centerline pipe, and five-hole prove measurement. |
