Updated 09/12/15 – This year’s Ewing Event will look at the scientific and engineering challenges faced by engineers and scientists working with or on magnetics in extreme environmental conditions.
- Mr Michael Pinnock from the British Antarctic Survey will discuss the severe engineering challenges of making ground-based and airborne geomagnetic measurements in Antarctica, and the space physics/space weather applications of geomagnetics, forecasting the impact of solar activity on satellites and ground-based technology systems.
- Dr Michael Weickhmann of Vacuumschmelze GmbH & Co KG will discuss the novel treatment of the magnets and specially thin slicing of the lamination stacks to reduce power losses on the engines of Solar Impulse 2, the round the world solar aircraft.
- Bartington Instruments will talk about their work on deep sea drilling and on RAL / NPL projects on space gradiometers for space applications.
The Ewing Event will conclude with a reception at which the 2015 Lifetime Contribution and Denis Hadfield awards will be presented, followed by the Ewing Dinner in the Rocket Tower, under some excellent examples of extreme engineering in the shape of the Blue Streak and Thor Able rockets.
Tickets are available for either the lectures or the reception / dinner, or a cheaper, combined ticket gives access to both.
Discounted rates, giving entrance to both lectures and reception / dinner, are also available for larger Tables of 4 or 8.

How to reduce losses and obtain maximum power density in PSM machines with magnetic materials and technologies for aerospace application.
by Dr Michael Weickhmann of Vacuumschmelze GmbH & Co KG
Reduction of losses in PSM machine by using Ni-Fe or Co-Fe instead
of Si-Fe laminations. Further improvement may be achieved by profiling the permanent Nd-Fe-B or Sm-Co magnets or by using new grades. The theme of this presentation is to show how to reduce size and weight of a motor and at the same time increase power density.

Space Weather: The Earth's Magnetic Field Shaken and Stirred
by Mr Mike Pinnock of British Antarctic Survey, Natural Environment Research Council
The talk focuses on two extreme environments: the near-Earth space region and Antarctica. The Earth’s magnetic field provides vital protection to planet Earth from energetic solar particles, but some of this energy does leak in to our atmosphere. The consequences for technological systems are briefly described, leading to why mankind now has a requirement to produce space weather forecasts. Measurements
of magnetic fields are central to the forecasting network that is required, both in space and on the ground. As a significant fraction of solar particle energy is guided by the geomagnetic field in to the polar regions, it follows that ground-based measurements on polar icecaps are required. The engineering challenges of making, and sustaining, such measurements will be described. The talk will also briefly touch on the role of airborne geomagnetic measurements in uncovering the geological
secrets of a continent covered in up to 4 km depth of ice.

How remote can it be?
by Mr Olivier Masseglia of Bartington Instruments
The presentation will look at 2 projects at the 2 ends of the altitude scale:
The first is about surveying boreholes in the ocean floor in order to
predict the future. (using Magnetic susceptibility to assess the climate at known time of the earth history to build up a model of the climate and predict the effect of global warming (Canterbury Basin Sea Level Expedition as part of the Integrated Ocean Drilling Program)).
The second is about assessing the magnetic signature of a spacecraft during measurements of Gravity waves, (a compact magnetic field gradiometer (as part of the LISA Pathfinder program of the European Space Agency)).
