Winship Elementary School
No full textBlack and white copy taken from an original picture of Winship Elementary School. Winship Elementary, located at 1412 Fifth Avenue north, was built in 1903. The name came from the founder/editor of the Grand Forks Herald, George B. Winship, who was also a longtime supporter of the school system.
After only three years of being open a fire destroyed the school, but was rebuilt and opened again in 1895.https://commons.und.edu/gf-city-photos/1295/thumbnail.jp
V-22 Osprey Proprotor
No full textThis paper covers an aerodynamic analysis of the Boeing Bell V-22 Osprey proprotor blade by utilizing thin-airfoil theory (TAT) and lifting-line theory (LLT). The primary focus is how the coefficient of lift and induced drag respond to changes in the angle of attack of the proprotor blades. The proprotor blade is modeled as a finite wing based on the NACA 63-212 airfoil. The wing has a geometric twist of -35 degrees from root to tip. The theories used to evaluate the blade design are limited by the assumption of incompressible, inviscid flow. The results of the analysis indicate that lift coefficients are maximized at high collective blade pitch of approximately 50 degrees to overcome the geometric twist necessary to evenly distribute lift over the span. Additionally, rotating the nacelle drastically reduces the coefficient of thrust from 0.09 to 0.02 as the fixed wings of the aircraft take over lift generation and the proprotor blades produce propulsion in airplane mode
North Dakota\u27s Children\u27s Homes & Foster Care During the Great Depression
No full textThis zine explores the experiences of children placed in North Dakota\u27s children\u27s homes and foster care systems during the Great Depression. As poverty, unemployment, and family instability increased, many children were separated from their families, revealing how economic crisis reshaped child welfare in the state, and how this affected families.https://commons.und.edu/history-hawks/1018/thumbnail.jp
