North American F-82E

[Rumpullpus 3,883]

The V-1710 143/145 had a Turbo compound system IE a turbosupercharger. Why are you being so picky about nomenclature?

because its not just nomemclature. they are completely different.

 

The original name for the TurboCharger is "Turbosupercharger." 

 

 

But like I said, as best as I can tell, the F-82E did not have a Turbocharger.  It literally had 2 separate superchargers, as opposed to the normal 1 supercharger that had 2-3 speeds. 

 

What difference does it make, you ask?  If it was set up as a supercharger, there would be peak velocities.  As it stands, setting it up as a turbocharger means that there really aren't peaks, and at all the middle altitudes it is overperforming from what it should be doing.

one has gears (low, high settings. like the P-51 and most other fighters) and is physically connected to the engine, the other has a compressor powered by the engine exhaust that is controlled with a waste gate (no peaks in engine performace. the engine performs @ SL ratings up to the altitude where the compressor cannot keep up. like the P-47, P-38). the only aircraft with inline engines to use a Turbosupercharger was the P-38.

Yes the paper i was reading mislead me

The F-82E had a single speed supercharger and a auxiliary variable speed supercharger

When is the F-82 getting hydraulics for all control surfaces?

When is the F-82 getting hydraulics for all control surfaces?

around the same time it can actually dive faster than 490mph.

[SubRyan 5,556]

around the same time it can actually dive faster than 490mph.

 

Well the limit was 505 mph IAS

[Rumpullpus 3,883]

Well the limit was 505 mph IAS

+10-15% safely factor....

[SubRyan 5,556]

+10-15% safely factor....

 

The thing that I think is odd is that some planes redline at their IAS limit, some planes below their IAS limit (F-82), and some above their IAS limit

[Rumpullpus 3,883]

not really odd. just sloppy.

 

it would be really odd if they did it right the first time (manual limit + safety factor). I expect them to get these things wrong now.
