X.3389 To Mr. Plumpton from EH. EH1/LG161118. 16th Nov. 1918. X.3254 X.1830 X.1827 X.1831 X.3389. It should be pointed out to Mr. White Smith that Condor" engines are being made of two types possibly three types of reduction gear. One will be a simple epicyclic gear giving .66 reduction the second is a compound epicyclic gear which will give .55 reduction. There is then another type of gear having .55 reduction but which has a friction controlled spring anchorage for the sun-wheel. This is intended to be used on sea planes where the propeller striking the water produces very large stresses. The HP. Curve of the "Condor" engine is as follows:- REVS. Petrol 25% Benzol added to petrol 1400 478 520 1500 518 554 1600 559 586 1700 596 616 1750 610 620 1800 624.3 642.6 1900 648.1 654 2000 658 669 The normal revs. of the engine is 1750. It can be run up to 2000 revs. for short periods. The consumption is .52 pts.HP.hr. This may be improved upon. The weight of the engine with the .66 reduction will be 1200 to 1250 lbs. With the other types of reduction gear it will be somewhere about 1350 lbs. As regards deliveries, we hope to have the | ||
