PurposeThe purpose of this paper is to optimize the downrange for hypersonic
boost‐glide (HBG) missile under near‐real condition, and to validate the
suitability of proposed wall cooling materials.Design/methodology/approachThe
trajectory optimization problem is characterized by a boost phase followed by a
glide phase. A multi‐phase trajectory optimization tool is adopted to optimize
the downrange... hiện toàn bộ
The mechanism of stress formation in glass under‐going conditions of rapid
cooling, and the factors affecting the properties of the toughened glass
produced are discussed. The application of techniques for measuring the
temperature of glass, to the control and study of the toughening process are
described.
PurposeThe purpose of this paper is to apply a factorization‐based control
system design procedure to design of auto‐pilot
systems.Design/methodology/approachThe design approach is based on a previously
developed factorization‐based control system design procedure. The design
approach requires a stable coprime factorization of the plant, a set of stable
coprime factors that are solutions to the Be... hiện toàn bộ

Under this heading are published regularly abstracts of all Reports and
Memoranda of the Aeronautical Research Council, Reports and Technical Memoranda
of the United States National Advisory Committee for Aeronautics and
publications of other similar Research Bodies as issued
THIS FEATURE covers simulators for technical training, and consequently are
designed for tasks other than the actual flying of aircraft. These include the
use of electronics, of ejector seats, the firing of missiles and finally air
traffic control.
A radical re‐think of the overall design and slide configuration of aerospace
profiling machines has been undertaken by KTM. The result is the new KTM FP 3015
profile centre, the first of which is currently being built in KTM's Brighton
factory.
