Summary of Scale-model Thrust-reverser Investigation
註釋Values of reverse-thrust ratio as high as 84 percent could be obtained if the gas were turned far enough and pemitted to attach to the cowling. Even without reversed-flow attachment and-with controlled reversed-flow pattem.s, all three types of reversers gave reverse-thrust ratios over 40 percent. The ring type with a 7 degree cowl gave 41 percent, the target type with a 7 degree cowl gave 49 percent, and the tail-pipe-cascade type with a 0 degree cowl gave 73 percent. All three types had satisfactory thrust-modulation characteristics. Thus, it was concluded that the selection of a reverser type may be based primarily on installation considerations rather than on performance characteristics.
