Robo |
 | | By the time of the final Robo presentation, Bell was far in advance of the other contractors. |
 | | They had refined their aerodynamic configuration in NACA wind tunnels, conducted systems tests of the water and sodium cooling designs, and studied in detail the problems of use of navigation, radar, and electronic and photographic intelligence systems aboard hypersonic aircraft. |
 | | They produced 39 papers by the end of Robo, working on their Model 1377 in collaboration with RCA, Honeywell, and Sylvania (avionics); Reaction Motors, Aerojet, and Rocketdyne (liquid propulsion); Grand Central (solid propulsion); and even studied nuclear propulsion. |
