I was wondering if one of those "big wing" designs could fix the accuracy problem with 30mm gatling gun.

http://www.whatifmodelers.com/forum//index...showtopic=15045

What would be better: long span and short chord or long chord and normal F-16 span?

I think the point will be to get stable low level flight.

Thanks in advance,
Carlos.

Dont think so because the accuracy problem wasnt due to the A/C. but rather the GPU-5 Gun pod & the pylon it was mounted on:

Precision aiming was impossible for several reasons:

The pylon mount isn't as steady as the A-10's rigid mounting;
The F-16 flies much faster than an A-10, giving the pilots too little time approaching the target;
Firing the gun shook the aircraft harshly and made it impossible to contro

I'm no aerodynamicist, but I dont think adding a bigger wing would do the trick. As for your wing question (*if* I understand my Aerodynamics 303 class), For your purpose it's better to have long span/short chord (kinda like the A-10 )


Ev, feel free to correct me if I boobooed this thing up.

I think the third reason can be fixed with new wings, this could also help with the second reason (allowing the plane to fly slower). For the first reason, I am thinking in a semirecessed mount in the belly. Should I protect the air intake?

Replace it with a long straight wing, with plenty of room for ordnance, add a second engine and split them well apart for redundancy. Then give it a twin tail, again for redundancy. And you'll want to protect the pilot, since this will be flying low and into ground fire, so you'll want to add some armor protection.

Hmm... sounds familiar.

Dumb@$ses in the Air Farce just won't do mudmoving, take it away from them and give it back to the Army. This is why the USMC has its own air support.

However, given this is what-if, I would definitely protect, or move, the air intake, because that big vacuum is the closest thing to the ground, and it'll be flying through dust and dirt and gunfire.

Changing the wings wouldn't affect the basic accuracy problem with the Gepod 30mm gunpod as a pylon mounting can not be as rigid as a built in, hard-mounted gun.  For an A-16, you'd be better off to use the 30mm cannon off the JA37 which uses the same ammo as the GAU-8, mount it internally in place of the M61, and provide a new ammo drum and feed system that fits the structural interfaces that are in place in the F-16.  Alternatively, use a derivative of the GAU-12 sized to fit the envelope of the M61 and develop an ammo drum and feed as described above.  You have to live with the existing structural constraints on the drum installation because changing them would by way too expensive since the installation sits on the joint between the forward and center fuselage.  I think I'd rather mount the gun internally than externally if possible.

Now, if you're wanting to go slower, you definitely want the longer span with reduced, or zero, sweep (like the QF-16 one shown in another thread).

Hi Evan,

I like your idea of JA-37 30mm cannon. But going a bit further, What if the 75mm ARES gun mounted in a f-16?

Thanks

[Shasper]

Well, you'll need a bigger engine to keep the a/c airborn. Remember the a-10 can come to a FULL stop in mid-air due to the recoil of the GAU-8, this is why they only fire off a 2-3 sec burst (also to keep the barrels from melting)

I think that's going a bit too far.  I'm not even certain that the ammo and feed system could be accomodated with the existing F-16 structure.  On top of that, the ARES 75mm gun has a rather longer barrel than the M61 and this wouldn't help the aircraft's aerodynamics.  I suggested the KCA because it would fit and uses the same high-performance ammunition as the GAU-8.

Hi, people,
I just like the long wing config.  
http://www.whatifmodelers.com/forum//index...showtopic=15045
I was wondering ... would it make a good stratospheric fighter? I want to build a F-16 (with pilot) this way.

Thanks,
Carlos.
