中國科學院力學研究所研究員、懷柔激波風洞項目負責人 姜宗林: 第一個尺度大。我們這個風洞吹出來這個流場有2.5米的直徑, 一般國外最大直徑的話1.5米,這樣的話你可以放更大的飛行器。 第二個時間長。在馬赫10的時候我們達到40個毫秒,比國內國際 的同類先進水平大概要有幾倍、成倍提高,實驗的結果的精度也 高了。第三個總溫高,總壓高,性能高。現在可以做到2500攝氏 度到18000攝氏度,而總壓的話,我們可以做到100個大氣壓一直 到10000個大氣壓。所以這個性能的話在世界上沒有其它風洞可以 比的。

However, according to a researcher and professor, Chris Combs, an expert on hypersonics and aeronautical engineering, from San Antonio, the claims about the JF-22 hypersonic tunnel ignores the presence of a wide variety of decades-old facilities around the world. “In terms of defense vs space, when they talk Mach 30 that’s pretty much exclusively space. Also, I am not sure in terms of physics what is gained for Mach 20 vs Mach 30. But there are plenty of places that can do Mach 5-8ish (I even have a Mach 7 tunnel),” Combs told EurAsian Times. He says there are lots of different ways to get to Mach 20+, with several facilities present around the world that can do that. “With that said, they can likely run that facility at lower Mach numbers for more defense-centric applications,” he added. Most hypersonic test tunnels have existed since the Cold War to test space vehicles and missiles in the United States. NASA has built many such test facilities over the decades to study countless rockets and spacecraft that the space agency sent to space. Combs says the article doesn’t mention how they will handle the fact that a detonation-driven shock tunnel will alter the air chemistry to the point that the aero will no longer be representative of flight.

不過中國專家認為,即便建設30倍音速的風洞, 唯一不可能的用途就是製造30倍音速的高超音速武器。
專家稱,30倍音速超過第二宇宙速度(每秒11.2千米; 每秒525千米為第四宇宙速度,即飛出銀河系所需最小 初始速度),飛行器若以這個速度在大氣層中飛行, 需克服巨大阻力和氣動加熱,而且在打擊效果上沒有 明顯優勢,經濟上更划不來。
沒有高超音速武器需要加速到這個速度。 https://news.cyol.com/content/2017-11/29/content_16730903.htm
