Please "chime" in

[Paulw]

This week I got in some parts that I have needed for a long time in order to finish up some long standing builds. One of these is the canopy to the AV-8B Harrier II + which I got from Chef. I really want to finish this but there is one question I have. Does any one have any idea what the undersides of the chines on the Harrier look like? Any pics?
The kit has what looks like an unfinished surface and it needs another part but there isn't anything in the kit to make it with so I need to know.

I have exhausted my resources and I really cant locate any pic with good enough detain to get a good reference.

Sorry Paul, can't help on this. I'm an old stuff fan and have very little on anything modern.

 

[jknaus]

Will look when I get home.

I don't think I have ever heard the term before. I'll be googlin' for ya Paul.

Is this what you're talking about, the area at the wing root?

A chine is a longitudinal sideways edge or extension of the fuselage or other aerodynamic body. The chines on some aircraft, such as on the Lockheed Blackbird, are part of the forward fuselage, blend into the leading edge wing root and form significant (lifting) aerodynamic surfaces in their own right].

They are the thin, fin-like things behind the nose gear, right? Not sure what you mean- they would be kinda streamlined, I would guess.

Well Bill Spidle got a good shot for us.

the things on the belly are strakes, the chine is the round winglet lookinh yhing between the fuse and the wing root.

From Prime Portal http://www.primeportal.net/hangar/av-8_home.htm I'm guessing this is where MP got the pic

What in particular are you looking for Paul?

[Adam Baker]

Not 100% sure, but I think the chines are the 2 panels at the leading edge wing roots.

So does that give you what you're looking for Paul?

 

[Paulw]

yes it does and now I can shape them the way they are supposed to look.

[RichB]

They are actually called LERX, Leading Edge Root Extension, and are designed to generate vortexes over the wing to improve maneuverability. There are two sizes for Harriers, 65% and 100% LERX. The ones in the pics are 100% LERX.

The under fuselage strakes are part of the LID, Lift Improvement Devices, and include a retractable fence panel just behind the forward main gear. The system improves the VTOL capabilities of the Harrier by trapping a cushion of air that bounces off of the ground from the engine exhaust.

Cheers,
Rich

Thats great info Rich, I thought those things on the bottom were some sort of add on for ECM or other package like they did to the top of so graceful lines of the F16.

 

[Paulw]

Thanks, Rich. I am glad to know that. The problem I have with the trumpeter lit is that while they are supposed to have some sort of aerodynamic shape the trumpeter wing section that they are on has them flat with a slight curve. I don't have a pic right now but as I get back into it Ill include pics to what I mean.

 

[Paulw]

Here is the problem I am having. I am trying to figure the best way to eliminate this flat spot and maybe put some sort of an air foil shape to the extension.

 

[chukw]

It may well be fairly flat! Of course, I know nothing, much like John Snow.

 

[moon puppy]

Phil I would fill it in where the cut off is back to the wing root. OR...Sand down that thickness at the leading edge. Leave the leading edge intact, just take that rib off, make sense?
