Footballers
are able to produce curved ball flight paths by imparting spin to the ball as
they kick it. The basic mechanism whereby lift forces are produced by spin is
well known (the Magnus-Robins effect), however, success in measuring the effect
in a wind tunnel study has so far been illusive. The main problems concern the
mechanical difficulty of supporting and dynamically balancing pressurised
footballs. The present project seeks to design a rig for spinning a machined
hollow sphere, whose surface can be modified to represent the effect of surface
texture on actual footballs. A key part of the design is in developing a drive
motor and mechanism that is located inside the model football. This
removes the need for spinning support rods, and also allows for future
measurement of surface pressures during rotation using a remote data
acquisition system.

Recent work at Manchester has demonstrated
the feasibility of organising large numbers of flight vehicles using a number
of simple rules based on the flocking behaviour of birds. Previously, Virtual
Reality Mark-up Language (VRML) animations have been developed by hand, however
the process is laborious and prone to errors. The present project will use the
recently released Virtual Reality toolbox in Matlab to develop animations based
on output from an existing Matlab flocking program.

Disc wings are a class of tailless flight vehicles that are stabilised in flight using spin. Typical examples of disc wings include the Frisbee sports disc, the discus and the clay pigeon. Previous work at Manchester has established a theory of flight for disc wings based on wind tunnel tests of a spinning Frisbee. The next stage in the work is validate tunnel measurements through free flight tests using a microcontroller data acquisition system onboard the Frisbee. A key requirement of the flight data acquisiotin system is measurement of disc attitude with respect to the gravity vector. To achieve this, it is proposed to use an optical horison detection system based on an array of light sensors around the disc. Previous work has established the basic charactersitics of the light sensors and a 2d algorithm for predicing attitude based on results from a light box experiment. The present work seeks to extend this to the 3d case with allowance for disc rotation.

The maximum thrust of high bypass turbo fan engines during take off is often limited by the effects of cross wind induced inlet separation. This problem is alleviated by decreasing the curvature of the side inlet lip, however this has adverse affect on cruise drag. A potential solution is to keep the geometry the same, but use active flow control actuators in the form of micro air jets that are activated when separation is detected. The present project is concerned with investigating the interaction of air jet flow control actuators with inlet lip separation following a shock. The work will be experimental, based in the transonic wind tunnel at Barton. Data will be obtained from surface flow visualisation, schlieren and pressure measurements.
