Regarding the VK-1600 I only found this:
The recent crash of the light transport prototype shows that Russia needs to introduce new heavier class engine types.
No it doesn't... the aircraft crashed because the engine that failed didn't feather and the thrust on one wing from the running engine and the high drag from the props on the stalled other engine caused the aircraft to roll and crash into the ground.
What it needed was an auto feathering system that worked faster.
Having engines that are too powerful just make them less efficient and more expensive to operate.
smaller engines is just begging for problems.
The engine was not under powered, the problem was the prop blades didn't feather.
Some whip cracking needs to be done since the western parasite corporate culture
is creeping in. All of the sudden everything is so expensive and corners need to be cut. Except that the engineers are not making
more money and the cost of raw materials has not jumped.
Obviously firing everyone involved is the best solution so that they can make all the same mistakes again because of a lack of experience of the new team who are only doing the job because the preferred team got fired.
Engine problems are very specific... why should the entire management team be fired because of such a problem?
Is it really that more expensive to fly an Il-76 than that of these other smaller planes? I mean, how much cheaper?
A combination of rather more expensive, but also involving unable to operate from more isolated airstrips too.
It is simply not practical to just have big aircraft.
Would you trade in the family car for a 50 seater bus?
Get all the groceries in one trip for all your friends and family... for a month.
The best way to ruin an aircraft design is to give it the wrong engines.... more power is just stupid and wont solve the fundamental problem.... the aircraft rolled over because of the thrust from one side and the drag from the other side... extra power would have made no difference to what happened, while a propeller that feathered properly when shut down would have saved the aircraft because it would be able to fly with one engine running.
