TECHNICAL: AIR TRANSPORT MPC 75-100 MPC 75-200 MBB/Catic offer new-look MPC75 New engines, configuration and cabin layout are being offered by the MBB/Catic team marketing two versions of the West German/Chinese MPC75 regional airliner. Both now sport turbofans beneath the wings in stead of unducted fans or propfans at the rear beneath a T-tail as originally planned. MPC is offering the Rolls- Royce Tay 700 (see Headlines) or a version of the Allison GMA3014 instead of the propfan, which was rejected on technical risk grounds. Accord ing to MPC president Jiirgen Thomas, ". . . we had to weigh the anticipated advantages against the considerable risk, which is difficult to calculate". The baseline aircraft will have a range of up to 2,800km (l,500nm) with speeds above 380kt (700km/h). The MPC75- 100's nominal range will be 3,150km (lJOOnm), but extend able to 5,000km (2,700nm) as a customer option using a centre wing tank. The -100 will have single-class seating for 89 in a 28.4m-long fuselage, while the - 200 will offer 115 single-class seats in a 33.2m-long fuselage. CBA-123's FORWARD FUSELAGE FINISHED Assembly workers at Embraer's Sad Jose dos Campos factory are complet ing the forward fuselage of the Embraer/FAMA CBA-123 regional airliner. The rear fuselage, made by FAMA in Argentina, and the wings have now been fitted. A maiden flight is scheduled for June, delayed because of late delivery of parts by FAMA. Both versions will have five- abreast seating. The -100 will have a maxi mum take-off weight (MTOW) of 39,000kg and an empty operating weight of 24,000kg. The -200 will have an MTOW of 46,000kg and an empty weight of 26,400kg. Maximum operating speed will be 330kt (612km/h). Maxi mum certificated altitude will be 39,000ft (11,900m), and take-off field length at 600m field eleva tion and ISA +15° is estimated at 1,670m. Thrust requirements vary from 63kN (1,4,0001b) for the -100 to 74kN for the -200. Noise limits will meet John Wayne Airport-exempt class at MTOW. Nitrous oxide emissions are targeted at 30% below cur rent turbofan limits. The aircraft is being offered with a low approach speed of 125kt (230km/h) indicated air speed to be combined with an economic cruise speed of M0.77. An identical, 30.4m-span high- aspect-ratio, low-drag wing will feature on both versions. Fly-by- wire flight control is also being designed into the MPC-75 from the outset to provide full flight- envelope protection. Struc turally, the MPC75 will feature extensive use of composites. The MPC 75 pre-development phase began in January last year and is scheduled to run until 28 June, 1991, when MPC hopes to launch full development and production of the -100. Partners are still being sought, and MPC is having "serious discussions with aerospace companies all-over the world", about risk sharing. First flight of the MPC75-100 has been scheduled for October 1994, with certification planned for December the following year. Customer deliveries are set to begin in January 1996 and certification of a longer-range -100 is set for October 1997. Programme go-ahead and development of the MPC75-200 is expected in December 1995, certification in November 1998 and first deliveries in 1999. • NEWS IN BRIEF RJ TAILPLANES Canadian Aircraft Products has signed a C$6.5 million ($5.6 million) contract to supply Canadair with tailplanes for 53 Regional Jet 50-seat aircraft in a deal which could lead to work worth C$45 million over ten years. The firm makes tailplanes for the Canadair Challenger. JETSTREAM GRAPHICS British Aerospace is to buy 20 colour graphics terminals from Westward Technology, to be linked by an Ethernet network to a Digital Equip ment VAX mini-computer, for Jetstream 41 computer-aided design. 10 FLIGHT INTERNATIONAL 18-24 April 1990
