Old designs with modern engines

It looks like the J-79-engined Voodoo had various cooling scoops on the extended jet pipes. That may chime with the fact that IAI had to provide significantly more cooling scoops (including the distictive fin-root one) when shoe-horning the J-79 into the Mirage airframe to create the Kfir. Similar mods may have been neccessary to a J-79-engined F-3H Demon.

The colour photo of Voodoo landing is the JF-101A, the first of the really long afterburner Voodoos. The NF-101A is the black and white photo. (Which was showing up and then not showing up, I've changed to yet another source for the url. If it keeps doing a dissapearing act, I'll upload a copy to the What If server.)

Easy fix - Change the RoE's!     

When you have a meddlesome, incompetent bag of dogcrap like LBJ who insists on PERSONALLY getting on the radio to individual B-52 tail gunners and telling 'em "y'all can't shoot back no matter what that MiG's about to shove up your arse"?

This is where living in Whif World has its perks.

Something I've long pondered is a "Super Strikemaster", i.e. how would you do to the JP.5 what Cessna did to the T-37 to make the A-37B? The A-37B got its relatively huge weapons load by having twice the installed power of a T-37, so how would you do that to a Viper-engined Jet Provost?

Didn't the A-37B have to carry more fuel tanks than desired as a result of this though? Ironically I have wondered if an uprated Viper in a Dragonfly could work.

As to the JP/Strikemaster, how about a Viper 633-47 as found in the IAR-93 Vultur

I believe you're right about the T tail issue.

The J85-GE-17A of the A-37B is 150lbs lighter and has 150lbs more thrust than a Viper ASV.12. The Viper is also 7" greater in diameter and uses more fuel. Installing the Viper would be a retrograde step.

A problem with the A-37 was the fact that the extra tanks created so much drag it nearly cancelled the extra fuel.

The root cause (pun intended) of pitch-up is swept wings stalling at the tips before the roots, causing the centre of lift to move forwards and the nose to come up. What T-tail blanking does is make it harder to recover from this by robbing the aircraft of pitch authority in exactly the conditions in which it needs it most.

Never seen the B&W until you mentioned it - I've looked at it now by following the link in your post.

I was talking about the colour photo of the aircraft landing. It definitely has different jetpipe features to the production F-101B, so if it has a J-57, then maybe they thought it needed more cooling then found out it didn't?

2nd time of asking in a couple of weeks, but why do I have to constantly read quote after inserted quote ? Can't people simply edit posts ? 

Well on the upside, it means you have the whole conversation in one post rather than having to scroll back through the thread to follow it...

As far as I'm concerned that is not an answer.

The colour photo is of the JF-101A, an F-101A with long afterburner J57-P-55 installed. It was a test aircraft used in
F-101B development, and the scoops were for afterburner cooling. It was used to set the air speed record on 12 December 1957 in Operation Fire Wall. Eclipsing the FD.2 record set in 1956.
The JF-101A record only lasted until March 1958 when it was surpassed by an F-104.

When one is on a phone, or tablet, it's often not that easy to select and cut large blocks of text. It's particularly clumsy with the forum software and it's fairly craptastic version of WYSIWYG formatting.
Not everybody is still pounding away on a PC.

Well I still am, mainly because I find it far easier to use a keyboard given my hand/eyesight problems, and regardless of any difficulty in editing posts on phones or tablets, which I cannot comment on as I havn't tried to do it, it still makes my life more awkward.  However if it is so then at least it makes things more understandable.

Personally, I generally find posting regardless of platform from a phone with tiny onscreen keyboard more trouble than it's worth, even my tablet has a keyboard folio to make it a "mini-laptop."

I use a phone and its a little clumsy, but I make a habit of trimming my posts.It doesn't take much effort.
