Regioliner R92/R122
Type: Family of 95/125-passenger short/medium range transports.
Program: MoU signed March 1991; formal launch expected October 1992; first flight of R92 expected Autumn 1995; expected in service at end of 1996: R122 expected in service about Autumn 1998.
Customers: Expected market 2,100 95/125-passenger airliners from 1996 to 2009 (excluding ex-Comecon countries and China), based on fairly optimistic trade and travel assumptions. Regioliner expects to win 30 percent of this with 300 R92s and 400 R122s, 43 percent sold in North America and 32 percent in Europe.
Costs: The 2,100 aircraft forecast would give a business volume of $58 billion (in 1990 US dollars) and the Regioliner share would be worth $19 billion (in 1990 US dollars).
Design features: Allowance for all cost-effective new and emerging technologies; computer integration carried into a centralized management system; low noise and emission levels; good field performance and manoeuvrability to reduce airfield occupancy; ability to operate economically over wide speed range to accommodate ATC requirements.
Flying controls: Fly-by-wire with sidesticks and electronic instrument displays. Four spoiler panels and four leading-edge slats on each wing; variable incidence tailplane.
Landing gear: Tricycle retractable.
Power plant: Two turbofans in the 69 to 82.3 kN (15,500 to 18,500 lb) thrust range; proposals from BMW Rolls-Royce; MTU/Pratt & Whitney, CFM International and Allison. R92 and R122 both to have 10,700 liter (2,827 US gallon; 2,354 Imp gallon) wing tanks and 5,350 liter (1,413 US gallons; 1,177 Imp gallon) center-section tanks.
Accommodation: Five-abreast cabin layout with wide aisle and asymmetric overhead bins. Large underfloor cargo hold. R92 holds 95 single-class passengers at 81 cm (32 in) pitch or eight first class at 91 cm (36 in) and 80 economy class at 81 cm (32 in) pitch. R122 holds 125 single-class passengers at 81 cm (32 in) or 10 first class at 91 cm (36 in) and 102 economy at 81 cm (32 in) pitch. Very high cabin comfort standards; very large underfloor baggage/freight capacity.
