Transcription
We get really close with out professors, and I think that they're just they're very inspiring people. They're just so friendly and we call them by their first names. It becomes very personal and I think, I think that's really nice for us as students to know that we can be comfortable with our professors. I really love the Grand Valley Campus. I think it's beautiful in the winter, and in the summer, and in the fall especially because there's so many trees everywhere. I really like the art that is everywhere around campus. I love how there is sculptures and paintings and stuff everywhere. I think that the best advice you can give an international student is to get involved in things. That's kind of a thing for a lot of people but you come here and you kind of don't have any friends, and you don't have any family, and the only thing that you can do is just get involved in something right away. It's nice to feel that you're a part of something and like I belong here. I mean a lot of times I forget that I'm an international student because I just feel so at home. So I think that just find a hobby, find anything that you like and you're guaranteed to find a bunch of friends.
Design and development
Jacobs designed the Weihe to be the pre-eminent performance glider of its era and indeed it captured many championships and set many records, until its performance was surpassed at the end of the 1950s. Even today it is considered one of the "classic sailplane designs".[1][2]
The Weihe is of wooden construction with fabric covering on the wing trailing edges and the control surfaces. The spar is built from Baltic Pine, with a birch leading edge D-box, fuselage and the fixed portions of the tail surfaces. The airfoil is a modified Gö 549-M.2 section. Early versions took off from a dolly and landed on a fixed skid, while later versions has a fixed wheel and skid undercarriage. Originally fitted with DFS-style airbrakes, some were later modified for Schempp-Hirth style brakes instead. The aircraft incorporates a unique rigging system which was widely copied in later gliders.[1][2]
Initially the aircraft was produced by Deutsche Forschungsanstalt für Segelflug (DFS) (English: German Research Institute for Soaring Flight) and later by Jacobs-Schweyer. Post World War II it was produced by Focke-Wulf as well as in France, Spain, Sweden and Yugoslavia. Production of the Weihe totaled over 400 aircraft.[1][2]
Operational history
The Weihe won the World Gliding Championships in 1948 and 1950. It was used to set many world and national records, including the world record for altitude gain in 1959 of 9,665 m (31,709 ft).[1][2]
Dick Johnson won the US National Soaring Championships in 1959, flying a Weihe.[2]
