ROLLS ROYCE - BRISTOL LIAISON MEETING MINUTES OF 2ND POWER PLANT INTERCHANGEABILITY SUB-COMMITTEE MEETING. (1) S.B.A.C. STANDARDS - ISSUE 2. It was agreed that the time was now ripe to consider a second issue of the S.B.A.C. standards, because gear boxes are now universally used in conjunction with engines. There is no reason, therefore, for them to be placed in front of the bulkhead, as was necessary when Issue 1 was laid down, owing to the fact that some engines drove the auxiliaries direct from the engine. The disadvantages of the gear box in front of the bulkhead have been referred to by various Departments of the Air Ministry as interfering with interchangeability from the store point of view, and complicating maintenance, owing to the necessity of breaking the connections between the aircraft and the auxiliaries. If the box is mounted in the aircraft structure behind the bulkhead, it will be possible to leave all the auxiliaries in position connected up when the Power Plant is changed. It was agreed that Bristol Company and Rolls Royce would investigate the possibility of standardising the position, direction of rotation and speed of rotation of driving shaft to pass through the bulkhead to which the gear box could be connected. This was to be done for all engines. (2) CONTROLS GENERALLY It was agreed that, so far as Controls were concerned, the Stirling should be left as Bristol Company have now got it, and Rolls-Royce will arrange to make the Griffon Power Plant to suit the Bristol installation should occasion arise. A meeting is to be arranged with Messrs Shorts, to be attended by Mr.Jewitt and Mr.Cowdrey, to clear up this point relating to this installation. The same remarks also apply to the AW.41. The Bristol Company agreed that the S.B.A.C. standard controls would be applied to the Folland machine incorporating Group III Scheme A.{Mr Adams} These controls could also be used on all other Group III machines. The Bristol Company agreed that they would adopt the S.B.A.C. standard controls for Group II Issue 2, in which the gear box is to be placed in the aircraft structure behind the bulkhead.
