RV. X4516. Hs{Lord Ernest Hives - Chair}/Lid.{A. J. Lidsey}1c/AD6.7.32. 20/25 COMPARATIVE RADIATOR TESTS Further to Hs{Lord Ernest Hives - Chair}2/AD4.7.32 and Hs{Lord Ernest Hives - Chair}/Lid{A. J. Lidsey}3/MA2.7.32, we have weighed the radiators used in the comparative cooling tests on Brooklands, the weights being as follows :- (1) Empty radiators :- R.R. hexagon - 74 lbs Marston Mark III - 80 lbs Harrison - 78 lbs (2) Radiators filled with water :- R.R. hexagon - 109 lbs (28 pints water) Marston Mark III - 116 lbs (25.75 pints water) Harrison - 109 lbs (23.5 pints water) We are therefore obtaining 35% increased cooling with the same radiator weight in the case of the Harrison block i.e. for the same cooling our radiator weight could be reduced 35%. We have interviewed Marstons concerning the Harrison block. They are extremely interested and are looking into the manufacturing problems with a view to producing this type of radiator matrix in England. They stress the point of using a simple shape of matrix from the standpoint of ease of manufacture, cost, efficiency and structural strength. Hs{Lord Ernest Hives - Chair}/Lid.{A. J. Lidsey} | ||
