Flying qualities and flight control system design for a fly-by-wire transport aircraftGautrey, Jim 09 1900 (has links)
Fly-by-wire flight control systems are becoming more common in both civil and
military aircraft. These systems give many benefits, but also present a new set of
problems due to their increased complexity compared to conventional systems and
the larger choice of options that they provide. The work presented here considers
the application of fly-by-wire to a generic regional transport aircraft. The flying qualities criteria used for typical flying qualities evaluations are described
briefly followed by analysis of several past transport aircraft flying qualities programmes against these criteria. From these results, some control law independent
design requirements are formulated for a civil aircraft for the approach and landing
task. These control law independent flying qualities criteria are intended to be used
with any generic rate-like control law for a transport aircraft and enabled a number
of different control laws to be designed.
The results of a number of flying qualities evaluations are presented. Both an ILS
approach task and a formation flying task were used. The effects of windshear
were also considered. It was found that control laws which maintain flight path are
suitable for the ILS approach task, while most rate-like response characteristics give
good flying qualities for the formation flying task.
Finally, the conclusions drawn from these evaluations are presented, and both the
Civil and Military current airworthiness requirements are assessed.
In addition to the flying qualities work, a study is made of the management issues
associated with fly-by-wire design. A fly-by-wire aircraft design programme was
proposed and the project management issues associated with this were considered.
A timescale was proposed for the design process for a generic regional aircraft, and
the critical path for this process is presented. / EPSRC; Avro International Aerospace.

The Creation of Long Distance Directional Plasma Discharges via the Exploding Wire TechniqueSmith, David William Robin January 2008 (has links)
This thesis describes the work completed to create long
distance directional discharge using the exploding wire technique.
A historical literature review gives the previous works completed on
exploding wires dating back to 1780. The review also gives the
current understanding of the exploding wire phenomena.
The design and construction of a test set to create long distance
exploding wires is outlined. A capacitor bank, high voltage switch,
charging circuit, hand earths design and construction methods are
given.
The measurement of the impulse and charging voltage and current is
explored and solutions found. Design and construction of a Rogowski
Coil and associated circuitry is outlined. Development of software
made for reconstruction of Rogowski signals is outlined.
Results of testing of different wire explosions is given. It is
found that if the charge voltage of the capacitors is to high the
wire explodes to fast to remove all charge from the capacitors. If
the charge is too low the wire may not have enough energy to
explode. Conditions for maximum energy discharged by a plasma
shrouded exploding wire are found for varying wire diameters and
lengths up to 10m.
