I think I understand now. The window is in a door frame? The window is almost the entire round frame?
Interesting that I had the same idea for a homemade awning window. Hinge at the top with a 'stick' to open and close. In my design the stick would be metal so much studier. I figured the hanging weight of the stick would hold the window closed. Also, the stick and its hinge at the window would be adjusted in length to hold the window closed tightly. A steel rod for a stick and a neodymium magnet to hold the stick should work.

So without completely reengineering the window holdout perhaps just a rebuild with steel parts will do it.

You may need to go to a thicker plexiglass & then have some decent weatherstrip applied to the opening. Next would be a "camming" latch mechanism, which will pull the window into place & lock past center, while pushing the window out to provide fresh air as it locks in the open position. You will need to fasten the latch pivot onto the window with small screws & nuts to hold it in place. Sounds like an interesting project to occupy your mind for a while. Geometry, graph paper, compass & ruler will do it, then a bit of fab time in the shop for the mock-up, perhaps a milling machine or drill press will do the job. Fun stuff to me, but off-the-shelf is easier during the design & planning stage!
