Re: Should China pay reparations for the economic damage from the virus ?

I haven’t decided myself whether this is appropriate, while I don’t believe COVID was created ‘in a lab’ it does appear the Chinese government went out of their way to hide the extent of the problem, Ask yourself this one question first. Would any other country have handled it differently? And then...

Re: Those who fly airplanes with FBW flight envelope protections

Re: How much less thrust does a modern high bypass turbofan engine generates at cruise altitude as opposed to sea level?

Re: How much less thrust does a modern high bypass turbofan engine generates at cruise altitude as opposed to sea level?

Re: How much less thrust does a modern high bypass turbofan engine generates at cruise altitude as opposed to sea level?

It is very dependent on bypass ratio. A GE90-115B will have a bigger thrust lapse than a JT8D My bad. However in the big scheme of things the small difference between 78% thrust reduction (CFM56 / bypass ratio 6.6) and 74% (JT8D / bypass ratio 1.0) is somewhat less significant than the fact that th...

Re: How much less thrust does a modern high bypass turbofan engine generates at cruise altitude as opposed to sea level?

Due to air being thinner at such altitudes, RPMs being equal, less air will be pushed away to generate thrust. Another factor to decrease thrust might be that there's less oxygen available for combustion, hence taking away a bit of vitality from the engine, though I'd think that'd be an issue mostl...
