The Next-generation turboprop is a regional airliner concept proposed by Embraer, powered by turboprop engines.
Development
By May 2019, Embraer was considering developing a new family of turboprop regional airliners in the 50–70 seat range, complementing the E-Jet E2, so as to free engineering resources.[2][3] By July 2020, it had evolved into the 70–100 passenger range[4] In October 2020, Embraer released conceptual depictions of the 75–90 seat airliner, with a fuselage similar to the E-Jet and turboprops above a low wing but a different T-tail design. It would compete against older ATR and Dash 8 designs for 1.5 to 2 h flights over 500–700 nmi (930–1,300 km).[5]
In August 2021, Embraer released a new configuration with quieter aft-mounted engines for a 70-90 seat aircraft, with the E-Jet cross-section, aiming for a 2022 launch and a 2027/2028 service entry.[1] Over a 250 nmi (460 km) sector, a 74-seat TPNG 70 would burn 5% less fuel than a 70-seat ATR-72 and 13% less than the 80-seat Dash 8-400; while the 90-seat TPNG would save 18% per seat compared with the ATR, and 25% compared with the Dash.[6] Embraer forecasts a market for 2,260 turboprops in the two decades following 2022.[7]
