Hs.{Lord Ernest Hives - Chair} Hy.{Tom Haldenby - Plant Engineer} De. re Peregrine and J.3. Oil Coolers. The oil cooler we have made for Peregrine consists of a couple of Clayton-Still oil cooling elements arranged in an aperture in the middle of the radiator matrix, as shown in the sketch. The radiator matrix is already too large for its job and we think that some of it can well be spared. The oil cooler elements are arranged in series, so that the oil passes up one and down the other. The oil connections to the engine are run through close to the fulcrum of the engine mounting at the front end, so as to interfere as little as possible with the flexibility of the latter. We are hoping that the experiments will show that this oil cooler is more than adequate for the Peregrine, but owing to the unknown nature of the quantities involved as regards air speed, etc. it is difficult to forecast the result. If the cooling is, however, found to be more than | ||
