A number of new material combinations for flexible connecting sleeves has been
developed by Northern Rubber making it the most comprehensive range available.
THE usual formulæ for deflexions and bending moments in curved beams, as given
in standard textbooks (e.g., Refs. 1 and 2), are not easily applied to the
relatively flimsy closed rings used as stiffeners in contempory aircraft design.
Two kinds of difficulty arise; one of computation, the other of principle.
THIS has already been dealt with in some detail in the first article describing
the aerodynamic features of the VC10, but it is relevant here to discuss the
controls from the systems viewpoint. Eleven powered flying control units are
incorporated in the system; four aileron units, four elevator units and three
rudder units. The units are fully‐powered and arranged such that each operates,

THE glider presents a simpler problem to the performance calculator than does
the engine‐driven aeroplane: a problem free from the variables that are
inevitably introduced when propulsion is derived from a complicated system of
engine and airscrew. Nevertheless, the process of determining the performance to
be expected of any projected glider design is usually quite a lengthy one; and
if, in addit... hiện toàn bộ
An aircraft undercarriage of the tandem type comprising in combination: an
undercarriage leg, a common axle journalled in the said leg, one arm fixedly
connected to one end of the said axle and a second arm rotatably mounted on the
other end of the said axle, stub axles mounted on the free ends of the said arms
parallel to the said common axle of the latter and pointing in opposite
directions, and... hiện toàn bộ
THE need for serious attention to fire precautions is becoming increasingly
important in satisfying the demand for improved overall flight safety. The need
arises from a number of considerations, of which the following are typical:
THE aircraft fuel modifier developed by ICI Paints Division could be a
technically viable approach to reducing loss of life through fire in impact
survivable air crashes, a Congressional Hearing in Washington was recently told.
