The Ball-Bartoe Aircraft Corporation was a US aerodynamics research firm and aircraft manufacturer established as a joint venture between Ball Corp and aerodynamicist Otto Bartoe in Boulder, Colorado in 1973. The firm conducted research into blown wings as a means of increasing aircraft lift at low airspeeds and constructed a research aircraft, the Ball-Bartoe Jetwing, as a testbed for these studies. The firm was dissolved in 1978. [1] [2] [3]
