194 FLIGHT International, 9 February 1967 AIR TRANSPORT ... Fairchild Hiller F-228 ON FEBRUARY 1 the Fairchild Hiller Corporation announcedplans to build the first short-haul jet to be designedspecifically to suit the needs of America's regional air- lines—an estimated market of 250 aircraft. Designated F-228, the aircraft is a 50-seat short-bodied version of the 60-seat Fokker F.28 Fellowship with power provided by the new- generation Rolls-Royce RB.203-01 Trent of 3:1 by-pass ratio and 9,7301b-thrust in place of the 8,6501b-thrust Spey Junior in the F.28. It is the first announced application of the Trent, which was revealed at the SBAC Show at Farnborough last September; the engine is also under consideration for the projected Hawker Siddeley HS.136 and the NAMC CX military/civil transport project. Production of the F-228 will be under a co-operative con- tract between Fairchild Hiller and Fokker acting together with its European partners HFB, VFW and Shorts. The F-228 will use the F.28 tail group made by VFW, components of the fuselage made by Fokker and HFB, and a portion of the wing structure built by Shorts. Some of the same systems will also be used. Fairchild Hiller has ordered 50 sets of com- ponents. The first F-228 flies in late 1968 and will be ready for airline service early in 1970. The terms of the contract also provide for the F-228 and the Fellowships to be sold in parallel—by Fairchild Hiller in the western hemisphere and by Fokker in the rest of the world. Despite its smaller overall dimensions and with normal seating for 50 instead of 60 passengers the F-228 is expected to weigh some 3,0001b more than the Fellowship. The gross weight is to be 5001b more with the net result that the new version will carry a slightly lower payload on short stages. However, a 12.5 per cent increase in installed thrust for take- off shows in a substantially improved airfield performance which is, in fact, comparable to that of the previous generation of twin-Dart feederliners—the Friendship, Herald, 748 and YS-11. A feature of the Trent of equal importance to its favourable ratio of cruise thrust to take-off thrust, is a signifi- cant improvement in fuel consumption offered. This is reflected in the full-tanks range (without reserves) of the F-228 which is 1,900 miles compared with 1,620 miles for the Fellowship at almost the same take-off weight but with the same fuel tankage. It is a design objective that the landing weight of the F-228 will be within 5001b of the maximum permitted gross weight for the best short-haul operating flexibility. No indication has been given of the expected selling price of the F-228, though this will obviously be a critical factor. Estimated direct operating costs of the F-228 predict an aircraft-per-mile cost of $1.34 on 100-mile stages with an annual utilisation of 2,500hr, compared with $1.1 per mile for the turboprop FH-227 which, incidentally, is to remain in production. With 50- and 56-seat accommodation respectively the equivalent seat-mile costs are estimated as 2.66 cents for the F-228 and 1.97 cents for the FH-227. The F-228 has roughly half the size, weight and payload-range performance of the One-Eleven, DC-9 and 737, and, FH claims, will have SHORT-HAUL JETS Powerplant Thrust (Ib) Dimensions: Length (ft) Span (ft) Height (ft) Wing area (sq ft) Weight: Gross (ib) Landing (Ib) Zero Fuel (Ib)APS (Ib)* Max fuel (Ib) Accommodation: Seatingt Hold (cu ft) Performance: Take-off (ft)* Landing (ft) §Max cruise (kt) Max payload (Ib) -range (n.m.)U Max range (n.m.) -payload (IbH VFW-414 BS M45H 7,700 70.5 70.5 2S.0 688 35,000 33,000 30,27022,060 10,800 40 — 3,300 3.960 3958,000/ 750 2,000/ 1.700 F-228 R-R Trent9,730 86.7 78.8 27.8 822 54,500 54.000 46,30033,800 17,800 50 475 4,000 3,400 43512,500/ 870 3,500/ 1,900 COMPARED F.28 R-R Spey Jr 8,650 90.0 77.3 27.8 822 54,000 51,500 44,20030,640 17,800 60 440 5,000 4,500 44013,560/ 930 6,160/ 1,620 One- Eleven 500 R-R.
