| Lr.{Mr Ellor}3/ADS.4.32 contd. -2- With regard to the cooling air supply, the effect of the increased fan capacity is very illuminating and demonstrates an interesting possibility for application to aero engine honeycomb type condensers which we have had in mind for some time. If at all possible, it will be very useful to find out what power is required to drive the fan and to compare this power with the equivalent drag power for the same cooling. A further point which must not be lost sight of in the car experiments is that under the present dynamometer test conditions the exit air has a free outlet, whereas with the bonnet fitted the discharge resistance will be greatly increased unless louvres of adequate size are provided. Presumably this item will receive attention when the system has been proved satisfactory. LR.{Mr Ellor} | ||
