A very interesting report on MC-21 by AirInsight. Analysis, however, presents MC-21's performance with Pratt and Whitney engines (even with those it is broadly superior), not with PD-14, which should improve performance even more. As analysis states:
The MC-21 will be a strong performer, and our independent economic analysis confirms that this aircraft will have compelling economics if the aircraft meets its projected performance. With flight tests underway and confirming fuel burn and other performance factors, we expect the MC-21 to be the most competitive civil aircraft ever produced in Russia, with compelling economics and low capital costs. If the aircraft performs reliably and can be readily maintained, we expect it to be a market success, projecting more than 1,000 deliveries over the next 20 years.
The Report itself is expensive ($ 500) but they still provide the table:
Plus, makes this important conclusion:
The MC-21 is the first of the next generation of narrow-body aircraft, competing primarily with re-engined models of aircraft that first entered service 51 and 29 years ago.
It is a crucial distinction since MC-21 is the only fully new and thoroughly contemporary mid-range aircraft on the market, including its latest state-of-the-art composite wing and systems. This adds additional "angle" on the issue of Russian sanctions--nobody likes strong competitors. It is very clear where the arms market goes with Russia "coming out" with a whole new cluster of weapon systems. Now, commercial aviation? There are many unhappy campers out there. This market segment is the juiciest one.
