The reverse thrust system provides means of decelerating aircraft during the landing roll, thus reducing landing roll length. The thrust reverser units are attached at the turbine outlet case of each engine.... The reversers are controlled by reverse thrust levers and operated by 13th stage engine bleed air. When not in use, the reversers are held in the locked position by 13th stage air and a mechanical lock. Each engine throttle has an additional handle which is used to actuate the thrust reversers. The reverse thrust lever pivots about a point near to the top of the throttle. If reverse trust is required, the throttle must be retarded to closed and then the reverse thrust lever must be pulled up. Further aft movement of the lever will increase reverse thrust.  3, record 2, English, - reverse%20thrust%20lever

These so-called "electric winds" are ion flows, moving at relatively high velocity.

... the Blended-Wing-Body(BWB) concept represents a potential revolution in subsonic transport.... In this study, 800 passenger BWB and conventional airplanes were compared for a 7000 nautical mile design range. ADP-class engines were used with technology levels keyed for a 2015 entry into service(EIS). In every measure, the BWB was found to be superior to the conventional configuration. Key findings for the BWB include : TOGW 15% lower[;] OEW 12% lower [;] Fuel-Burn 28% lower [;] Thrust 27% lower [;] L/D 21% higher [;] DOC 13% lower [. ] The BWB advantage results from a double-deck cabin that extends spanwise as well as lengthwise providing structural and aerodynamic overlap with the wing. This reduces the total wetted area of the airplane and the deep stiff centerbody provides efficient structural wingspan. Relaxed static stability allows optimal span loading, and a trailing-edge high-lift system is not required. Further synergy may be realized through buried engines that ingest the centerbody's boundary layer and thus reduce the effective ram drag.  2, record 14, English, - blended%2Dwing%2Dbody%20project

Intertia friction welding. Two workpiece parts to be joined are clamped rigidly in a sturdy fixed unit usually called the tailstock fixture and a rotating chuck assembly or collet drive. The spindle assembly, which includes one of the workpieces and any required flywheels, is rapidly accelerated to a pre-calculated speed, storing the energy required for welding. The spindle is disconnected from the drive source and begins to freewheel. At the same time, the ram assembly moves the non-rotating part axially to force both workpieces together, also a predetermined calculated(lbs.) thrust load. While the workpieces are thrust tightly together, friction between the interfaces convert kinetic energy stored in the rotating spindle and flywheel assemblies into heat at the interface, and finally into mechanical working of the plastic metals.  3, record 15, English, - Inertia%20welding
