Opps,

  Look what I started.....

 Atleast it's keeping the thread active.... without beating the horse.

 

[Scherf]

Heheheh,

I'll see if I can't find another "stubs" pic and return the thread to my original whine...

 

[Scherf]

Here ya go.

This is RS625 of 143 Squadron.

It's got stubs AND rockets AND drop tanks!

(Pilot's notes say the tanks had to be dropped before the rockets were fired, can't think why....)

Scherf:

 Here's a question for you,ever notice the dorsal fillet on the Hornets??

 Much like the ones added to the B17 or P51,I wonder why it wasnt added to the Mossie?

 BTW,that pic is sweet,has a calm purposed effect about it,oh and do I see foofighters attached??

[Die Hard]

Why were the ejector stubs angled downward so much outboard of the engine? There was no radiator to protect there. Even on the inboard side it seems drastic to angle the stubs down that much.

Wouldn't want that wing leading edge getting all crispy.

[Die Hard]

Sure, but the angle looks extreme for that. Must be wasting half or more of the exhaust thrust.

"up" thrust would help too I'd think as it would reduce, slightly, the lift required of the wings and therefor the parasitic drag.

[Die Hard]

Parasitic drag has nothing to do with lift. Drag caused by lift is called (lift) induced drag. At high speed induced drag is an almost negligible part of total drag. Unlike parasitic drag which is proportional to the square of the airspeed, for a given lift, induced drag on an airfoil is inversely proportional to the square of the airspeed. In other words if you double the speed the parasitic drag increases four times, while the lift induced drag is reduced to a quarter of what it was.

Quite right.  I had a mental hiccup it seems.

[Die Hard]

Happens to everybody.


For anyone still wondering, here's a nice picture of what I'm on about:




As illustrated, parasitic drag is the limiting factor for speed. The faster you go the less relevant induced drag gets.

Hot air rises thus giving extra lift under the wing.

Yeah, I've wondered about that, I think there were comments that the Mossie needed more fin when one engine was out, especially at low speed.

The Hornet fillet is pretty substantial; my best guess (and it's no more than that) is that a similarly-solid fillet would have pushed the Mossie's CG too far back. It was fairly far back (IIRC) with bomb-bay tanks and wheels up, so...

Not that any of that prevented Mossies from getting home "on one" from all manner of nasty far-flung places.
