A need has been established in industry and academic publications to link an
engine’s maintenance costs throughout its operational life to its design as well as
its operations and operating conditions. The established ...
In the motorsport environment, where traction at one wheel is often compromised
due to high cornering accelerations, Limited Slip Differentials (LSD) offer significant
improvements in traction and vehicle stability. LSDs ...
Fracture and toughening mechanisms in rubber modified and hybridized urethane-methacrylate
resins have been investigated. Fracture mechanisms are defect-dominated in the unmodified
resin. The relationships between defect ...
As far as design of composite structures is concerned, it is important that we are able
to accurately determine the failure modes and damage progression of structures made
of composite materials. This will in turn, aid ...
A new method is developed to deal with shape optimization problems. The
core idea of the method is to introduce the knot insertion algorithm which
keeps the geometry unchanged while increasing the number of control ...
Gas turbines have been used since the 1940's to provide
electric power at times of peak demand, but this is due to low
initial cost and short starting times. Historically low
efficiency and a higher quality fuel requirement ...
In recent years much work has been done in many countries on
the development of powered artificial limbs for use by adults and
children with congenital deficiencies i.e. present at birth, and
by amputees.
The established ...
Unfettered competition in the US and Canada has resulted
in a much more efficient airline industry, but the considerable
economies derived from the resulting structural change has lead
to greater levels of concentration ...
This thesis studies the dynamics and control of flexible articulated space manipulators
with large payloads similar to the Space Shuttle Remote Manipulator System. For
dynamic response analyses an exact analytical method ...
The dispersion of air into water was studied in a tall agitated vessel (ungassed liquid
depth = 2.4 x vessel diameter) fitted with four different triple impeller combinations:
1. Three identical Rushton turbines
2. One ...
A general method for the optimal design of large laminated
composite structures, that allows full design variable (ply
thickness and orientation) freedom, has been developed .. The
number of variables and constraints, ...
This research was spawned by the questions and answers from the 33rd
report of the committee of Public Accounts session 1983-84. The Key
to the ensuing arguments about the report hinged on 3 words "Best
Commercial ...
The literature available on the effect of vessel geometry, particle properties and liquid
properties on the distribution of solids in a mechanically stirred vessel has been
examined. This has shown that there are wide ...
The existence of belt misalignment in the Van Doorne metal pushing V-belt
continuously variable transmission (CVT) has always been recognised by researchers
and the manufacturers themselves. However, its effect has always ...
The effect of transpiration on the boundary layer near the leading edge of a swept wing
has been investigated using a large swept cylinder model with a laser-drilled titanium
leading edge to model the leading edge of a ...
A combined experimental and theoretical study is described of the low speed flow over a
highly swept and cambered wing that simulates the flow features of a transonic manoeuvre
condition. The thesis is divided into two ...
This thesis addresses navigation and guidance which will be required for air
traffic management in Future Air Navigation Systems (FANS) and Free Flight. In
particular, the thesis covers the issues of data fusion and ...
The flow inside a vortex controlled diffuser was studied experimentally and theoretically. The experimental side of the study included the following:
(1) The selection of a suitable laser Doppler velocimeter for the ...
For decades Liquefied Petroleum Gas (LPG) has been considered as one o f the most
prominent alternative fuels to petrol. LPG typically consists of propane, butane and
propylene, but also smaller quantities o f methane ...
The objective of this thesis was to investigate flame
radiation and smoke emission phenomena in a combustor typical
of those in use in aircraft gas turbine engines. One of the
primary aspects of the investigation was ...
