Turbo is just an air compressor driven off exhaust gasses and can even serialize them (twin turbos are common in BMW and Audis). Depending on the turbo and manifold design, its normal for turbo engines to maintain sea level performance at high altitude (IIRC they are called turbo-normalized engines...

vina

What altitude? A series of army articles point out that even turbocharged internal combustion engines lose power at Tibet altitudes. Upto 25000 ft? That is why you turbocharge. The turbocharger will boost the manifold pressure to sea level (in an ideal case)... WWII piston engine fighters had super...

OT. But in a traditional car, your fuel consumption is higher at idle and at redline, than at economical cruise speed. That is because the fuel air mixture is richer at idle.

Well, let's put numbers. If a restaurant works just 300 days a year for a sales of 75lakhs, you are looking at a daily sales of just Rs 25000. Now any small darshini type in a major city will easy see this turnover Andy pay 18% gst.

Guys, Dr Saraswat said that in his talk in Aero India. For the VikAd /Gorshokov, the only aircraft that will fit is the Mig 29K. The problem is the height of the hanger.

You can't just geometrically scale up or down a design. Of course you can. In fact.

I think GE136 is also contra-rotating. Only way to reach such extreme T/W, but it makes sense: you basically halve the mass by eliminating the stators, and you can probably push the stage pressure ratio a lot higher.
