其二见本期学报另一简讯。其三摘录的内容如下:交大航空系抗战时由于战乱未建风洞,在重庆时常借用中央大学的风洞为学生开出实验。搬回上海后,1947年曾筹得款项准备在美国订购一套风洞建设试验台。曹鹤荪为此曾给在美国的级友钱学森写信,请熟悉此事的钱学森协助,钱学森当时也积极为母校奔走接洽,但最终此事因故未成。不过,交大航空系此遗憾几年后由交大人在新中国的哈军工得到弥补并大放异彩。从1953年到1963年间,由交大航空系调入的马明德和岳吉毅两教授,在哈军工负责设计建立了从低速到超音速不同尺寸的八个风洞组成的风洞群,当时由 Second, see another newsletter in this issue. The third excerpt reads as follows: During the war of resistance against Japan, the National Chiao Tung University Aviation Department did not build wind tunnels. In Chongqing, it often borrowed wind tunnels from the Central University to experiment with students. After moving back to Shanghai, he made preparations in 1947 to order a wind tunnel construction test stand in the United States. For this purpose, Cao Hsun-Sun wrote a letter to Qian Xuesen, a classmate in the United States. Qian Qiansen, who was familiar with the matter, assisted Qian Xuesen in her active running for her alma mater at the time, but eventually the incident failed. However, National Chiao Tung University Aviation Department regretted that several years later by the National Chiao Tung University in Kazakhstan to get the new Chinese workers make up and shine. From 1953 to 1963, Ma Mingde and Yue Jiyi, two professors transferred by the National Chiao Tung University Department of Aviation, were responsible for the design and construction of wind tunnel clusters consisting of eight wind tunnels of different sizes from low speed to supersonic speed.
