COMMONWEALTH ENGINES 1955 AMONG the engines manufactured in the Commonwealth**• countries and referred to in the following pages, three are of indigenous design, the Commonwealth Aircraft Cicada andthe Orenda Engines Orenda and PS-13. Originally intended for the Winjeel, the Cicada has been wholly designed, manu-factured and developed by the Australian Commonwealth Air- craft Corporation. Production has been suspended on thisengine, which is a seven-cylinder air-cooled radial weighing 770 lb, of 46.5 in diameter and 58 in length, and developing450 h.p. at 2,600 r.p.m. at sea level. Two twin-stage-turbine models of the Orenda series of turbo-jets are currently in production, the Orenda 11 (Avro CF-100) and the Orenda 14 (Canadair Sabre 6). More than 2,500 engineshave been built by the Orenda company (previously the gas tur- bine division of A. V. Roe Canada) since its production plant wasofficially opened in September 1952. Since that time thrust ratings have increased from 5,800 lb (Orenda 2) to over 7,000 Ib(Orenda 11 and 14), and current costs are now averaging only $8 per pound of thrust. Modifications introduced during the past year on Orendaengines are described on page 300. The Mark 11 and 14 Orendas each possess a ten-stage axial compressor and six combustionchambers, as do the earlier versions fitted with single-stage tur- bines. The Mark 14 incorporates electronic exhaust-temperaturecontrol. Magnesium alloy is used for the air intake and compressorcasings. The compressor comprises three light-alloy drums bolted Orenda Engines Orenda 14. together, with one steel disc at the upstream end, all the bladingbeing of light alloy apart from the last stage which is steel. The combustion chambers employ Duplex downstream burners, therebeing a twin-manifold fuel supply fed by a Lucas pump at 1,500 lb/sq in. Bendix supply the full-range flow control unit. AllOrendas are at present started electrically (the Jack and Heintz starter being prominent in the photograph). This motor is fairedby a spinner which, in Orendas for the CF-100, terminates in a nose-cap bearing a pair of vanes. These vanes are spun round by ramair and each incorporates an alcohol spray for de-icing purposes. No official information has been released concerning the PS-13,or Super-Orenda, the two spool turbojet which, it is hoped, will eventually power the Avro CF-105. American and Canadianreports, however, have quoted a design rating of 18,000 lb thrust —25,000 Ib with afterburner—and a titanium content of 20 percent by weight. It is no mean task to develop an engine of the calibre of thePS-13, and Orenda Engines—together with the Hawker Siddeley Group and the Canadian Government—are to be congratulatedfor having taken so bold a step. Earlier this year the president of the company stated that Orenda had then spent four milliondollars in the development of the new engine, and the general tempo of PS-13 work is accelerating continuously. Today it islikely that component running has begun—in fact, it has even been unofficially reported that the engine is already running asa unit. Canada may, therefore, have the most powerful engine in the world.
