| (2) blower that can be accommodated by existing installations. (B) - 2 STROKE PETROL INJECTION. (1) DESIGN WORK - TWIN CYLINDER PROTOTYPE AND MAIN ENGINE. Wd.{Mr Wood/Mr Whitehead} reported that all details of the twin cylinder prototype unit with the exception of the cylinder block had been issued - schemes for the block are almost ready for detailing. Design work on the 12 cylinder main engine has been resumed. (2) DESIGN WORK - R.R. PETROL INJECTION PUMP. Design work almost completed. This pump is considerably smaller than any pumps which can be obtained at present and is positively operated, thus doing away with the necessity for using spring returns for the plungers. A weak link is incorporated in each plunger to prevent wreckage of the complete pump unit should seizure occur on one plunger. (3) TEST UNITS. Wd.{Mr Wood/Mr Whitehead} reported the position of the test units. The E.44 unit has completed 50 hours at 155 b.m.e.p. and 2400 R.P.M. The subsequent strip was very satisfactory. The programme for this unit includes further endurance running with a lower compression ratio. (4) TEST BED POSITION. Wd.{Mr Wood/Mr Whitehead} reported extremely slow progress with the No.2. test house for two twin Vee test beds. Hs.{Lord Ernest Hives - Chair} agreed to investigate the position. (5) CONTRACT POSITION. Wd.{Mr Wood/Mr Whitehead} reported the contract position - all work in hand is covered by contracts, with the exception of the following for which proposals are being drawn up and will be submitted shortly. (1) Manufacture and testing of two stroke Petrol Injection Pumps. (2) Manufacture of 12 cyl. two stroke petrol injection engine. (3) Manufacture of Vee twin unit (No.5) for work on the Kadenacy system at Armstrong Whitworth's. (6) AXIAL FLOW BLOWER. Gr.{George Ratcliffe} reported the position of the work on the Fraser & Chalmers axial flow blower at Bristol - the unit has run approximately 26 hours and the strip is good. Hs.{Lord Ernest Hives - Chair} requested Gr.{George Ratcliffe} to find out whether the makers would be prepared to manufacture a Second unit for R.R. | ||
