AHCA (Advanced Heavy Combat Aircraft) concept, 5/5.5/6gen? Su-30MKI replacement? TEDBF 2.0?

[Bhartiya Sainik]

For AHCA to be naval stealth jet, we should have some size reference.
On AMCA thread i showed comparison of AMCA & F-18 SH naval jet in medium class.
A naval jet & a heavy class means Su-33 as best current example.
A stealth jet & heavy class means F-22 as best current example.
Let's compare both towards conceptualizing a stealth, naval, heavy class jet.

Su-33
length 21.19m
width 14.7m
height 5.93m

F-22
length 18.92m
width 13.56m
height 5.08m






Observations:
> Naval Flanker is taller due to bigger landing gear, humpy bumpy airframe. While F-22 is continious block airframe like a flying brick.
> Due to humping, Su-3X front LG is also huge compared to F-22's.
> The rear landing gear of F-22 retracts laterally, while of Su-33 retracts forward that too w/o folding.
> Both their empty weight, Std./Stealth-TOW are almost same. Yet Su-3X family is huge size bcoz the airframe is stretched & humped resulting in hanging intakes.
> Wing loading is almost same. This is intresting.
> Su-33's external load with full & lower fuel is lower than F-22's, may be due to lower wing area.
> ATWRs (Aircraft Thrust to Weight Ratios) of F-22 much better than Su-33.
> F119 engine is 2.27 tons Vs 1.5 tons AL-31F3. Both are around 195" long. F119 inlet dia. is 40", AL-31 inlet dia. is 35.6". So F119 has higher volume & more weight due to TVC nozzle, ceramic RF blocker, etc.
> So the intake area is also more as seen in front view.
> The centerline area in Su-3X have 2 weapon stations. This space is aerodynamically enclosed in F-22 right from nose to form center part of IWB space. Remaining space comes from humping the intake ducts. The center space in AHCA can potentially house NG sized AGMs & VLR-AAMs.

There can be many more things to observe.

It is a good imagination for start.
Modified AMCA can carry 6 AAMs + 2 CCMs internally easily. Hence AHCA with tandem IWBs can carry 10-12 AAMs internally easily.
4 DEW pod equivalent space will be required.
Reduce cockpit canopy to 50-70% to give correct size impression. This jet is supposed to be bigger than F-22, at least the size of Flankers.

I answered him on another forum that -
This concept looks at least 22m long, equal to Su-3X, identical to J-36.
It is easy to imagine just 1 view, but difficult to co-relate all views together.
The center IWB is too much aft.
Bcoz the engine exhausts are close spaced & diameter of type weapon is more, so the IWB has to hang down more than a fighter's IWB, not very aerodynamic. The IWB start below the intake ducts, which will result in lowering of IWB. Otherwise you'll have to separate engines with centerline tandem IWB.
4.2 tons IWB capacity is huge for a 6gen fighter.
If it is a fighter-bomber or strike jet only for AF then something like J-36 might be possible. But 2 engines means very powerful ones.
Bcoz -NG is 6m long, so for a fighter, i can imagine 1x -NG on centerline similar to Su-30MKI carries the biggger one.

He should make a side view of this design with weapons superimposed, for better idea.

AMCA's Main IWB needs to be just stretched length wise by just 2 Meters to accommodate Brahm0s-NG

Height of IWB is 0.75 Meters so -NG won't have any problem in depth & width wise

Main iwb is 2.2 Metes wide and can have 2 x Brahm0s-NG side by side.....

Brahm0s Ng Diameter is 0.55 Meters only so only length of AMCA's IWB needs stretching

Do you remember this image which is shared by AGNI 6 ICBM ?


-----------------

This is what FB-AHCA might look from front view....


Removed Vertical stabilizers & horizontal stabilizers lie in same plane as wings

Wings would be little more thick & Side weapons bay will be in wings & central fuselage junction (Indicated by orange mark)

Ofcourse it can be done, but appropriate engine & wing design are needed for ATWR (Aircraft Thrust to Weight Ratio) & wing loading (wing surface area /MTOW).

I know all Agni ICBMs - Agni 6,5,4,3,2,1

Yeah he seems to be shy. Check page 1, 2.
