Mutual interference between jets and intakes in STOVL aircraftSaddington, Alistair J. January 2009 (has links)
During wind tunnel testing of jet-lift, short take-off and vertical landing (STOVL) aircraft it is usual to simulate the jet efflux but not the intake flows. The intakes, which are commonly faired over or are unpowered, are generally tested in separate wind tunnel experiments. The forces acting on the wind tunnel model are determined by the linear addition of the forces obtained from the two separate tests. There is some doubt as to whether this is a valid approach. A systematic experimental investigation was, therefore, conducted to determine the magnitude of any jet/intake interference effects on a generic jet-lift STOVL aircraft in transitional flight, out of ground effect. Comparisons made between separate and simultaneous jet and intake testing concluded that a mutual jet/intake interference effect does exist. The existence of this interference means that the aerodynamic wing lift loss in transitional flight deduced from isolated jet and intake testing is less than the lift loss obtained from simultaneous jet and intake testing. The experimental research was supplemented by some simplified computational fluid dynamics (CFD) studies of elements of the flow-field about the aircraft using the k-e turbulence model. The numerical modelling enabled aspects of the flow-field around the aircraft to be visualised which could not easily be done using the experimental apparatus. It is a requirement of the Eng]) programme that part of this thesis must address a management topic linked to the research. In this case the management aspects of wind tunnel project work were examined. A scenario was developed which established a requirement for a large-scale, low-speed wind tunnel with a Reynolds number capability of 20 million. A study was performed on the decision-making process and investment appraisal methods used in the procurement of such a wind tunnel.

Mutual Interference Between Jets and Intakes in STOVL AircraftSaddington, Alistair J. 28 October 2009 (has links)
During wind tunnel testing of jet-lift, short take-off and vertical landing (STOVL)
aircraft it is usual to simulate the jet efflux but not the intake flows. The intakes,
which are commonly faired over or are unpowered, are generally tested in separate
wind tunnel experiments. The forces acting on the wind tunnel model are determined
by the linear addition of the forces obtained from the two separate tests.
There is some doubt as to whether this is a valid approach.
A systematic experimental investigation was, therefore, conducted to determine the
magnitude of any jet/intake interference effects on a generic jet-lift STOVL aircraft
in transitional flight, out of ground effect. Comparisons made between separate and
simultaneous jet and intake testing concluded that a mutual jet/intake interference
effect does exist. The existence of this interference means that the aerodynamic wing
lift loss in transitional flight deduced from isolated jet and intake testing is less than
the lift loss obtained from simultaneous jet and intake testing.

The application of optical fibre Bragg grating sensors to an internal wind tunnel balancePieterse, Frederik Francois 04 June 2012 (has links)
D. Phil. / Conventional internal wind tunnel balances are designed and constructed to accommodate foil strain gauges which measure the deformation (strain) of the material. Foil strain gauge balances are known to be affected by electromagnetic interference and temperature. These balances are expensive and their manufacture is time consuming. With an increasing demand for higher accuracy, stiffness, increased resolution and temperature compensation, current balance designs are becoming inadequate. To overcome identified balance deficiencies a research programme in the application of optical Bragg gratings to wind tunnel balances was initiated. In this programme a new concept of using optical fibre Bragg grating sensors, with the advantage of using mechanical amplification to increase sensitivity, and the implementation of temperature compensation techniques was demonstrated on a simulated two component balance.
