(This is the sixth engine to be accepted). 2 hrs. at 9/10ths. rated power at 2100 r.p.m. 9/10ths. X 480 B.HP. = 432 B.HP. (126 B.M.E.P.) Final 5 mins. at full throttle. SUMMARY OF TEST. We have completed the two hrs. acceptance test on X-F-16. The full throttle power was 4 HP. lower than at the commencement of the run :- C.HP. at the start (with silencers) = 463. Oil consumption was at the rate of 4 pts/hr. Petrol consumption (9/10ths. rated power) .526 pts/HP/Hr. " " (at full throttle) .533 " " Relief valve (E.28244) When this engine was first put on test, the high pressure was 50 lbs/sq.in. and the low pressure practically nothing. The relief valve was removed and the springs were found to be according to drg. when measured and tested for loading. The flat springs (E74992/E.28161/2) locating the disc valves were found to have an initial set so that they contd :- | ||
