Bailey - Chief Engineer} ORIGINAL Hs{Lord Ernest Hives - Chair}3/LG29.1.29. 'F' ENGINE CARBURETTERS IN THE 'VEE'. V3933 WE expect this week to fit at least one of the service machines with the extra heating to the throttle. The great advantage of this will be that it will give improved and consistent running without any trouble from freezing up on the ground. This is a big point in the Squadron because at the present time we are asking them to fill up with warm water - it takes a long time to get the water ready and frequently by the time the machine is filled up, the weather is unsatisfactory and flying has to be abandoned. The extra water heating round the throttles will do away with the necessity of filling the engines with hot water. We have still got to face the fact that we may have trouble with freezing of the diffusers in the air. We are tackling this from two points: (1) We are altering the diffuser and reducing the amount of air passing through the diffuser by using a metering orifice similar to Stromberg. (2) By inside air intakes. The A.M. are prepared to consider inside air intakes. We attach a sketch of one we are building up with a number of thin aluminium plates. We have since heard that the French are using a mx{John H Maddocks - Chief Proving Officer} similar inside air intake on their machines with very satisfactory results.
