Flight Control System for The Boeing 2707 Supersonic Transport Airplane 670528
While the SST will operate in environments that are new to commercial passenger airplanes, its flight control system introduces no radical changes in operating procedures. All primary flight control surfaces are operated by triple, noninterconnected hydraulic systems. The normal mode of longitudinal and lateral control employs an electrical command system and mechanical backup is provided. Multichannel stability augmentation is introduced on all three control axes. Optimum lift/drag characteristics are assured through variable-sweep wings, direct lift control, and the secondary flight controls. Trim is accomplished by displacing the primary control surfaces.
Development of flight control system components is progressing on schedule.
