The Aeroplane Speaks [57]
upward during flight.
Wire, Anti-lift or Landing--A wire opposed to the direction of gravity, and used to sustain a surface when it is at rest.
Wire, Drift--A wire opposed to the direction of drift, and used to prevent a surface from collapsing backwards during flight.
Wire, Anti-drift--A wire opposed to the tension of a drift wire, and used to prevent such tension from distorting the framework.
Wire, Incidence--A wire running from the top of an interplane strut to the bottom of the interplane strut in front of or behind it. It maintains the ``stagger'' and assists in maintaining the angle of incidence. Sometimes termed ``stagger wire.''
Wire, Bracing--Any wire holding together the framework of any part of an aeroplane. It is not, however, usually applied to the wires described above unless the function performed includes a function additional to those described above. Thus, a lift wire, while strictly speaking a bracing wire, is not usually described as one unless it performs the additional function of bracing some well- defined part such as the undercarriage. It will then be said to be an ``undercarriage bracing lift wire.'' It might, perhaps, be acting as a drift wire also, in which case it will then be de- scribed as an ``undercarriage bracing lift-drift wire.'' It should always be stated whether a bracing wire is (1) top, (2) bottom, (3) cross, or (4) side. If a ``side bracing wire,'' then it should be stated whether right- or left-hand.
Wire, Internal Bracing--A bracing wire (usually drift or anti-drift) within a surface.
Wire, Top Bracing--A bracing wire, approximately horizontal and situated between the top longerons of fuselate, between top tail booms, or at the top of similar construction.
Wire, Bottom Bracing--Ditto, substituting ``bottom'' for ``top.''
Wire, Side Bracing--A bracing wire crossing diagonally a side bay of fuselage, tail boom bay, undercarriage side bay or centre-section side bay. This term is not usually used with reference to incidence wires, although they cross diagonally the side bays of the cell. It should be stated whether right- or left-hand.
Wire, Cross Bracing--A bracing wire, the position of which is diagonal from right to left when viewing it from the front of an aeroplane.
Wire, Control Bracing--A wire preventing distortion of a controlling surface.
Wire, Control--A wire connecting a controlling surface with the pilot's control lever, wheel, or rudder-bar.
Wire, Aileron Gap--A wire connecting top and bottom ailerons.
Wire, Aileron Balance--A wire connecting the right- and left-hand top ailerons. Sometimes termed the ``aileron compensating wire.''
Wire, Snaking--A wire, usually of soft metal, wound spirally or tied round another wire, and attached at each end to the framework. Used to prevent the wire round which it is ``snaked'' from becoming, in the event of its displacement, entangled with the propeller.
Wire, Locking--A wire used to prevent a turnbuckle barrel or other fitting from losing its adjustment.
Wing--Strictly speaking, a wing is one of the surfaces of an ornithopter. The term is, however, often applied to the lifting surface of an aeroplane when such surface is divided into two parts, one being the left-hand ``wing,'' and the other the right-hand ``wing.''
Wind-Tunnel--A large tube used for experimenting with surfaces and models, and through which a current of air is made to flow by artificial means.
Work--Force X displacement.
Wind-Screen--A small transparent screen mounted in front of the pilot to protect his face from the air pressure.
