[Aircraft Vibrations, Dr. Hsu Lo] , circa 1952 - 1955

The Purdue University sub-series contains Neil Armstrong's grade reports for 1948, a spiral bound notebook, various folders and two, three-ring binders which held Armstrong's class notes, assignments, labs, along with some quizzes, tests and finals from Engineering classes taken in pursuit of his undergraduate degree. Included are materials for Aeronautical Engineering, 310; 320 - Aircraft Windtunnel; 320-A - Aircraft Windtunnel Lab; 340; 350-A; Armstrong's experiment for 420 - "Preliminary Design Analysis Execution Transport;" 471 - "Aircraft Powerplants;" 481 and 481-A - "Aircraft Powerplants Laboratory;" an "Aircraft Vibrations" class taught by Dr. Hsu Lo and a "Subsonic Flow" class. The Mechanical Engineering courses include, M.E. 109; 521; 530 A and B - Advanced Heat Transfer. Math 523 is also included. The [G.E. 224] folder contains various handouts for [Aero. ED] courses. Additional material Armstrong placed in the binders are laminar flow calculations, "Canons of Ethics for Engineers," a booklet titled, Ratio of Total and Static Pressures for Mach Numbers and catapult diagrams and guide for carrier suitability testing. The catapult material appears to be from the Naval Air Test Center, United States Naval Air Station, Patuxent River, Maryland but was in a binder with Purdue class notes.

Located at the back of the second three-ring binder are Purdue "Varsity Varieties" papers from 1953-1954. The "Varsity Varieties" were an all-student revue, and Armstrong wrote and co-directed the short musicals in 1953 and 1954. Most of the notes are for his 1954 production, which he entitled, "The Land of Egelloc" (college spelled backwards). Lyrics for the short musicals are included.
