Il primo volo del nuovo PAK-FA

Cioe' i 35 mld sarebbero il 50% del totale?

Il T50 e' sostanzialmente un evoluzione del SU 35, non rappresenta per i russi la stessa rivoluzione che per gli USA e' stato l'F22/F35.

Problemi seri per il T 50.

Warplanes: The 5th Generation Is Cursed

October 4, 2013: The Russian answer to the American F-22, the “5th generation” T-50 (or PAK-FA) is in big trouble. Several key components are facing serious development problems. The key item in trouble is the new engine, which is still stuck in development. Russia always had problems building competitive engines. In the past to get the power needed they built engines that lasted only a fraction as long as Western engines. The Russian engines needed more maintenance, used more fuel and broke down more often. Back in 2006 the NPO Saturn company was selected to develop the engine for the T-50. This effort was expected to cost about $3 billion, or about 30 percent of the cost of the entire project. But Saturn ran into problems from the very beginning with its AL-41 (117S) engine. This forced the temporary use of the older and less capable AL-31 family of engines in the T-50 prototypes. The AL-31s are used in the Su-27/30 series of fighters and are the basis for the Saturn 117A. Saturn promised to produce a "Western Class" engine and has been unable to deliver. This does not kill the T-50 but makes it less capable and reliable.
The engine, unfortunately, is but one of several key systems that is arriving less capable than promised. The NIIP AESA radar built for the T-50 worked very well as a prototype but the manufacturer found that the hand-built prototype NIIP was difficult to mass produce. This had long been a Russian problem, made worse by 70 years of communist rule that discouraged the kind of entrepreneurial activity that made such things work in the West. The immediate solution is the throw more money at the problem but this is making the mass produced NIIP radar much more expensive than originally planned
