Why does exhaust flow inwards through a radial turbocharger?

In a radial compressor, the air enters centrally and passes outwards, aided by centrifugal force. But, as the diagram shows, in piston-engine superchargers the driving exhaust gas flows inwards ...

What is the difference between Full Throttle Height and Critical Altitude?

My understanding is that "critical altitude" is the density altitude at which the wastegate on a turbocharged engine is fully closed, so any climb will result in a decrease in manifold ...

How common are gear-driven or belt-driven superchargers in modern aircraft?

How common are gear-driven superchargers in modern piston-engine aircraft, either alone or in combination with exhaust-driven turbochargers? What are some examples of modern aircraft that use them? Is ...

In the modern aviation context, is the word “supercharger” generally assumed to mean a gear-driven system rather than an exhaust-driven system?

In the modern aviation context, is the word "supercharger" generally assumed to mean a gear-driven system rather than an exhaust-driven system? At one time the word "supercharger" often was used to ...

Did any WWII aircraft only use a turbocharger but not a supercharger?

In doing some basic research, I have concluded that all WW II aircraft equipped with turbochargers also used mechanical driven centrifugal superchargers. These include the P-38, P-47, B-17, B-24, B-...

Where do the compressed gasses of a charged engine goes?

Good day to you here. I'm working on a modified version of 2-stroke engine. My plan is to use a supercharger for the scavenging process, instead of the conventional Crank case scavenging technique, ...

Can a turbo aircraft be converted to non-turbo?

I'm specifically thinking about the Arrow III. There are hundreds or possibly thousands of turbo Arrow III's, but almost no non-turbos. Could I buy an Arrow III Turbo (PA-28R-201T) that is at TBO ...

I overboosted an engine in a Mooney 231 - do I need to do an inspection?

I have an intercooler, but no wastegate. Manifold pressure was not controlled on takeoff and went to 50. The max is 37! If overboosting doesn't really exist because the relief valve opens, then how ...

To a pilot, does turbocharging differ from supercharging?

When it comes to operating an aircraft, what are the practical differences between a turbocharged engine and a supercharged engine? I'm aware of the mechanics - turbochargers being exhaust-driven, ...

How do turbochargers aid engine performance as density altitude increases?

How do turbochargers improve engine performance at high altitudes / density altitudes? Could you also address how this benefit could become a liability at low density altitudes, for example when the ...
