Record 1 2016-03-24

English

Subject field(s)
  • Aircraft Airframe
DEF

An aerodynamic surface fixed, movable or adjustable in flight, located aft of the main plane, contributing to longitudinal control and/or stability and which may add to, or subtract from, the total lift.

CONT

The horizontal tail is made up of a fixed and a movable surface. The "horizontal stabilizer" is the fixed surface and the "elevator" is the horizontal moving surface.

OBS

horizontal tail: term standardized by ISO.

Record 2 2000-07-25

English

Subject field(s)
  • Aircraft Airframe
OBS

... 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.

Record 3 1991-12-10

English

Subject field(s)
  • Air Transport
OBS

The ability to maintain stable, level flight, and to manoeuvre in a controlled fashion. There are three components to stability: roll, pitch, and yaw. Stability in "roll" is maintained and controlled by the ailerons; "pitch" is maintained by the dihedral angle of the wings, and controlled by the elevators; "yaw" is maintained by the keel effect of the fuselage, and controlled by the rudder.

DEF

A vane, either fixed or movable, in a jetstream, especially in the jetstream of a rocket, used for the purpose of stability or control under conditions wherein aerodynamic controls are ineffective.
