722 FLIGHT AIRLINERS OF THE WORLD U.S.S.R. . . . hundred passengers can be carried in addition to over 4,000 lb ofbaggage and some 6,000 lb of cargo. Weight has been saved by attach- ing the engines to the wing instead of to the fuselage frames, and—having regard to the higher wing loading—flap area has been increased. In a typical layout there are three cabins; the first for 30 persons insix rows; the second for 15 in three rows; and the third for 55 in Antonoy An-10 Ukraina. eleven rows. Between the first cabin and the cockpit is a galley, andaft of the third cabin are two wardrobes, two toilets and a vestibule. Range with a payload of 26,450 lb is of the order of 2,000 miles (includ-ing a 1-hr fuel reserve); speed approximates to the Tu-104A's. Tnpolev Rossiya This 170/180-passenger transport should now bealmost ready to fly. It is thought to have a cruising potential of 500/ 600 m.p.h. and a range of 4,300/5,100 miles. The type is destinedfor service with Aeroflot and has been reported as a civil development of the four-turboprop Bear swept-wing bomber, though this is uncon-firmed. The designation Tu-114 has been mentioned. PROJECTS BRIEFLY described on this and the next page are a number ofnew or projected transport aircraft. Excluded from the listare types which are featured in our special issues dealing with rotary-wing aircraft and the smaller executive machines. Agusta-Zappata AZ-8L Powered by four Alvis Leonides 550 h.p. radial engines, the AZ-8L, Italy's only airliner project, is now virtually complete. A low-wing machine of neat and clean appearance, it has a design weight of 23,810 lb and can seat up to 26 passengers. Cruising speed can be as high as 252 m.p.h. Avro 735 This number is believed to have been that coveringa projected transport variant of the cancelled 730 supersonic bomber. Avro have stated their intention to continue with thedesign of a supersonic airliner. Avro 740 On July 5 we reported upon this jet transport to theB.E.A. specification. Sir Rob Dobson, Avro managing director, then said, "We are risking many millions of our own money inthis venture. . . ." Like its competitors it is designed to cruise at 600 m.pJi. over stages up to 1,500 miles. Three-engined andfour-engined schemes have been studied. Avro STOL It has been reported that Avro have a designStudy for a 25-seat short-field transport. Blackburn B.107 Under this designation Blackburn have pre-pared a study for a Beverley development, with a pressurized fuselage of revised form, a retractable undercarriage and four5,315 h.p. Rolls-Royce Tyne engines. Payload should be well over 30 tons. Boeing 727 No single scheme designated 727 exists; studieshave been made but no early decision is expected. The model number covers a short/medium-range jet transport powered byeither two JT3s, four Avons, four JT8s, three CJ-8O5s or three Zephyrs. Gross weight at present lies between 80,000 and105,000 lb (one report avers up to 135,000 lb) and the design stage-length is from 100 to 1,000 miles. Breguet 941 Named Integral, this STOL is a novel fixed-wingmachine intended to lift a payload of at least 6,000 lb out of a 350ft strip. Four turboprops (G.E. T58s are envisaged) are spreadright across the 58ft wing and their big propellers blow back across the wing and double-slotted flaps. The first experimental machineis about to begin its flight trials. Further details were given in our May 31 issue. Bristol 200 In existence as a major project for over a year, theBristol 200 is a 600 m.p.h. jet to the B.E.A. specification. It has been studied in various configurations, one type having threeBristol Zephyrs (Olympus 551 series) at the tail-end and another having four Rolls-Royce R.B.140s alongside the rear fuselage. Britannia Development In our July 6, 1956, issue we gave acomplete appraisal of Bristol's design thinking at that date on later Britannias powered by Orion engines. Project work is stUl inhand on the Britannia 400 and on the larger Bristol 187. Canadair CL-44 Described in our August 23 issue, the CL-44is a development of the Bristol Britannia, powered by four Bristol Orion turboprops. Weighing between 185,000 and 200,000 lb,and cruising at over 400 m.p.h. for ranges up to 5,000 miles, the CL-44 is being marketed by Canadair as a civU and military freightand passenger machine for service from late 1959. Eight are on order for the R.C.AJF. CASA-207 Azor Powered by two 2,040 h.p. Bristol Herculesengines, this Convair-like aircraft has been flying in prototype form for many months and is relatively well-developed. Normaloperating weight is approximately 23,300 lb and gross weight 37,480 lb, provision being made for from 30 to 40 passengers inan unpressurized cabin. Normal cruising speed is 217 to 258 m.p.h. and the Azor has been designed to operate over stages from200 to 950 miles. Dassault Project As far as is known this French company arenot actually engaged in the design of a supersonic transport, although they have announced their interest in this field. On theother hand plans are well advanced for the development of a "Heron replacement" with outstanding short-field performance.It may have four 750 h.p. Turbomeca Bastan turboprops. D.H.121 This company model number refers to one of thejet transports under consideration by B.E.A. Powerplants are reported to be either three Rolls-Royce R.B.141s (scaled-downConways) or four R.B.140s. D.H.C.4 Caribou Designed as a multi-purpose utility trans-port for arduous civil and military short-field operations, the Douglas Model 1940.
