X. 3138 X. 3131 Meanwhile, he thinks that we should get on the new pumps without delay for the earliest possible engines, and should at the same time put through a relief valve experimentally on the lines we have already suggested. I said that we had hoped to get the new pumps on Eagle 1001 and Falcon 501 because it would be impossible to alter the engines after that date. He said that speaking unofficially he did not believe that there was going to be the slightest trouble about getting such an improvement on the engines after 1001, between that engine and 1600, and that any such alteration which does not involve structional alterations in the aeroplane, and which is an improvement either as regards weight, efficiency, or cost of manufacture, would never be opposed by the Air Board officials. X. 2341 Captain Briggs is sending us some photostat prints of petrol lifting systems, which he says are very promising, but which should be arranged to be driven from the engine rather than from a windmill as at present. He said that any time we wish to know any particulars of aeroplanes or aeroplane fittings, other engines, German aero engine, &c, he will be most pleased to obtain them for us. Oy. | ||
