MiG-19/J-6/Q-5, and I-370 (parallel develpment)

[dy031101]

Damn...... I should have saved the picture when China Defense.com Forum still had it......

As to the other question, the I-370 does appear to be somewhat slicker than the Grumman and Lockheed aircraft that used the J48.

Actually it would appear that Tay can propel Dassault Mystère to transonic speed...... okay, I'm getting off-topic now.

Here's a new proposal for an update / conversion kit to older Q-5 versions including a KLJ-7 radar + AAM's !

Today's messing around with blanks got me looking a bit more at the I-370......

According to this site, the I-370 has three variants: I-1, powered by VK-7; I-2, with quarter-chord sweepback increased from 55 to 57 degrees, and I-3, powered by the more-powerful VK-3......

According to the line drawings from this site, the I-1 and the I-2 seem to inherit from the MiG-15/17 the armament scheme of one 37mm and two 23mm cannons below the nose...... the line drawing of I-3, found at VAR Aviation drawing site, has wing root cannons of the MiG-19.

When was the I-3 rolled out?  I was trying to combine the forward fuselage of a Q-5 with the rest of the I-3, but I wonder if earlier prototypes would fit better with the timeframe of the introduction of Shenyang J-6 (IIRC, liscence agreement was made in 1958; the I-1 was rolled out in 1955).

[dy031101]

As it turns out...... the I-3 line drawing that I got is in fact that of the I-3U, also designated I-420 (the I-3 is also designated I-380).

Can I safely assume that the I-3U is a further evolution of the I-3, with a centrifugal-flow turbojet like that of the I-3?

EDIT: after biting the bullet and buying the SSP book, it would appear that the VK-3 as used by the I-3/I-3U is an axial-flow turbojet......

[dy031101]

I've always rather liked the SM-12, which was essentially a MiG-19 with much more powerful (axial) engines (can't remember the name - they wern't just uprated RM-9s though) and a sharp-edged, centre-bodied intake which looks remarkably like an early MiG-21 item.....

Flipping through the SPP book a few minutes ago got me thinking...... what would it have looked like if Shenyang (the concept began there before being transfered to Nanchang), instead of redesigning the forward fuselage, did something like the SM-12, using the intake centrebody to house a nav-attack system Like the Su-17?

A simple thought - given they were contemporaries, I wonder how a MiG-19 would look in a F-100 Vietnam scheme such as below?

This is a Soviet MiG in Command & Conquer: Red Alert 3.

The forward fuselage easily reminds me of the MiG-19- with that in mind, how could it have been put into practice?  I suppose the idea can be like the one behind the Bell D-188, except this one would have vectorable engine(s) in the central fuselage for both takeoff and cruise, and outboard engines for dedicated cruise and supersonic combat performance.

Given their extensive experience with the J-6/MiG-19, perhaps the PRC's military could even be the operator or creator of this what-if?  Given where the development of the J-7 actually began (at Shengyang before being transfered to Chengdu some time later), perhaps the evolved J-6 would even have absorbed some technology from the J-7......

Random idea moment:  MiG-19K Carrier based fighter.

Premise:  MiG-19 continues in development.    Swing wings added.   

[dy031101]

RATOBAR carrier or land-based fighter?  Installing a rocket engine in the central fuselage for takeoff and/or high-altitude performance?  Although in that case the nose intake would be rendered unnecessary.

Ah, forgot this one: the tilting-nacelles of the BAe P.103...... potentially how straightforward is the idea compared to designing an engine with vectorable nozzles?
