The flying test bed (FTB), developed for the purpose of studying the problems associated with hovering, vertical takeoff, and vertical landing of VTOL aircraft, was installed between two upright rails in a gantry of 9 m height and set on three 2 m stands. The permitted vertical movement was about 3.5 m. Running tests by remote control, ground operations tests by the crew, and climb and descent tests by the crew were carried out. The flight tasks given to two pilots were takeoff and landing, hover, climb, and descent by slow and step control. The height control test results showed that the height control systems, including the automatic stabilization equipment, have good speed-control-characteristics and sensitivity, although there was some backlash in the systems. The hovering characteristics were influenced by static friction between the FTB and rails, which assisted the pilot in achieving hover, but disturbed the pilot in leaving hover condition. (Author)
