Mais juste un pas au dessus !
Evidemment, si les Turbo-Fans gagnent 15% et bientôt plus, les Turbo-Prop's doivent maintenir leur marge !
Et tout le monde est sur le sujet ...
P&W se prépare activement (Plus qu'Airbus) pour le prochain Turboprop de 90 Pax, et peut être plus !
La gamme : 5 à 7000 CV, des écos de 20 % suivant les normes actuelles ...
ATR et Bombardier, comme clients potentiels ...
Une techno en développement, pour les compresseurs, et des éléments du GTF , pour la partie chaude (Et peut être le réducteur, c'est moi qui le dit ...)
Vu sur Leeham, de AIN !

Fresh Demand
According to Dussault, fresh demand for both the ATR family of twin turboprops and Bombardier’s Q400 series is prompting both manufacturers toward a launch decision for new larger models up to a maximum capacity of 100 seats. In his view, a cruise speed of a little above 300 knots is optimum to preserve the fuel-burn advantage of turboprops over jets.
---------
Turboprops consume 40 percent less fuel than jets on short segments, but jets are not standing still and this is why we need to achieve a further 20-percent reduction [in fuel burn]. I foresee a [regional airliner] market in which about 40 percent of the fleet is turboprops.”
-------------
Beyond that, the company would undertake the detailed design and procure hardware, with a view to conducting the first ground test within 18 months of program launch for the new aircraft. P&WC’s goal would be to achieve first flight on within 30 months and final certification within 42 months. “Everything now is about our readiness for when the market is ready for the new engine,” concluded Dussault.
