FLIGHT, DECEMBER 8, 1932 The Amazing Rolls As a result of the excellent service given by Rolls- .Royce " Kestrel " engines, it has been decided to in crease the rating of the " Kestrel " II S. Under the new rating the rated power at zero boost is 525 b.h.p. at 2,500 r.p.m. normal speed and at 11,500 ft. altitude. The maximum is 595 b.h.p. at 3,000 r.p.m. and at the same altitude. The maximum boost pressure in taking ofl is 2 lb./sq. in., and the sea level power at rated boost is 485 b.h.p. at 2,500 r.p.m. The engine has been passed by the British Air Ministry at this rating. We shall be sur prised if even 600 b.h.p. is the maximum at which the Rolls-Royce engineers are aiming. Monospars in Italy and France THE Italian Government is the latest authority to interest itself in the Monospar type of wing construction, and we are informed that they have placed an order with General Aircraft, Ltd., of Croydon, for a wing built on this principle. It is understood that this will be for a Caproni aircraft, possibly the type 97 which was shown at the Paris Show. This machine had an Alpha-Romeo " Jupiter " engine and was intended for light transport. Incidentally it was somewhat damaged in a fire during the Show. During the Show General Aircraft not only had a machine in the Salon, but also a demonstrator out at Le Bourget aerodrome. This created so much interest that it is staying there another week. Already the company is receiving numerous inquiries as a result of having their machines over there. ON TEST : B.T.H. magnetos are used all over the world in aircraft, and to make them fit for this work they have to be subjected to the most stringent of tests. Above may be seen one of their test benches on which the endurance test is carried out. The magnetos are run here for 8 hr. at 4,000 r.p.m. with the spark gaps regulated to make the output voltage 10,000. The Pobjoy " R " A FOLDER issued by Pobjoy Airmotors, Ltd., contains illustrated descriptive matter about the improved 1933 " R " 80 h.p. Pobjoy (described in FLIGHT October 13, 1932). During its comparatively young life this radial engine has achieved an excellent reputation, and the manufacturers are convinced of its ultimate adoption in many phases of aviation. We are reminded in the folder just issued of the Pobjoy's performances, of the flights over the Andes at 18,000 ft. by Mr. Taylor in March, 1932, and the record flight to Australia by Mr. C. A. Butler in November, 1931, the machines in both cases being Comper " Swifts." Well-Finished Aircraft MANY remarks have been passed to us concerning the excellent finish of the Fairey machines at the Paris Show. It is worth knowing that these as well as all the other British aircraft shown there were doped with Cellon Dope. The Belgian machines being finished with dope from the Belgian factory of the Cellon Co. Another Two-Stroke Aircraft Engine THE development of two-stroke engines for use in aircraft has always been the aim of a large number of designers, owing to the simplicity attendant on the two- stroke principle. The latest is an engine which is being developed by Messrs. C. G. Woodhouse-Temple and G. D. Devaney. This is a four-cylinder-in-line air-cooled engine having airscrew reduction gearing and claimed to give 120 b.h.p. at 4,500 r.p.m. for a weight of 100 lb. The bore and stroke are understood to be about 56 mm. and 110 mm. respectively, while the fuel consumption is spoken of as being only 0.38 lb. per b.h.p. ,/hr. ! This engine has already done considerable running on the test bench, but has not to our knowledge yet been type tested ; it is naturally supercharged to a high degree, this being, so it is said, in the region of 15 lb./sq. in. m m m m.
