Heavy weight MKI carries 8t while Medium weight Rafale carries 9t, why? ECO

[Riaz Hussain]

LCA Tejas
Empty weight - 6560kgs
Useful Payload - 4000kgs

Rafale
Empty weight - 9500kgs
Useful Payload - 9000kgs


Why is that Rafale which only a medium weight fighter and only 30% heavier than LCA, can carry 225% payload of the LCA? LCA can carry only 4000kgs and its empty weight is 6560kgs. Also this medium weight french fighter carries more weight than heavy weight MKI which can only carry 8000kgs. Not only that, its empty weight is the same as its payload meaning it can carry payload which is almost equal to its own weight. What is the physics and technology behind this amazing thing. What on earth did the french put in it? Asking this questions to indians because you will know better.

In su 30mki ordinance is 8tn load.
In rafale u add fuel+ordinance=9tn load.

 

[Agnostic_Indian]

good question, I also have the same doubt for a long time .

 

[GURU DUTT]

Data from Pakistan Aeronautical Complex about JF-17

Empty weight: 6,586 kg (14,520 lb)
Loaded weight: 9,100 kg (20,062 lb)
Useful load: 3000 kg (6600 lb)

So with nearly same wait of LCA, JF-17 had nearly 25% lower useful wait what u want 2 say on that boss. Aircraft's are are designed as per requirement and we have 2 sat French had done wonderful job that's why we are going 4 it.

now you have done the cardinal sin of PDF

good luck mate

Look at more specifications you will understand better.

It depends on engine and the weight of the plane. MKI is heavy so the empty weight plus the payload will make the engine lift more weight as compared to Rafale.

see MKI has other features such as more service ceiling and range. And after all they are different aircrafts with different roles.

I think the most important thing that you forgot to mention here is that..

Rafale is 9.5 tonne with engine producing Dry thrust 100Kn and Wet thrust 150Kn

and on the other hand

LCA tejas is 6.5 Tonne fighter with engine producing Dry Thrust 54 Kn and wet Thrust of 85Kn.....

 

[Wickerman]

What kind of question is this. Rafale is a two engine plane, producing more thrust. LCA is a single engine plane producing much lesser thrust, infact half.

Su 30 MKI:

Empty weight: 18,400 kg (40,565 lb)
Loaded weight: 24,900 kg (54,895 lb)
Max. takeoff weight: 38,800 kg (85,600 lb)

Rafale:

Empty weight: 9,500 kg (C variant), 9,770 kg (B variant), 10,196 kg (M variant)
Loaded weight: 14,016 kg (30,900 lb)
Max. takeoff weight: 24,500 kg (C/D variant), 22,200 kg (M variant) (54,000 lb)

LCA:

Empty weight: 6,560 kg (14,460 lb)
Loaded weight: 9,500 kg (20,944 lb)
Max. takeoff weight: 13,300 kg (29,100 lb)

I dont see where the MKI carries less than the Rafale.

A bus has more empty weight then say a truck because of so many passenger seats ,ac etc but can carry less weight then truck .. Some fighters are twin seater ,.you should have compared engine weight to its capacity ...

 

[rockstarIN]

it is the engine power which matters.

 

[OrionHunter]

Tejas is the smallest light weight mult role fighter in the world designed for electronic warfare, air intercept and close air support with reconnaissance and anti-ship as secondary roles. How can you compare its useful load to a Rafale which is designed for simultaneously undertaking air supremacy, deep penetration interdiction, reconnaissance, and airborne nuclear deterrent missions?

It's pointless comparing the two which have been designed keeping in view their roles.

For one thing, it is a much newer airframe than the flankers or F-16s. That is why the rafale weighs somewhere near the weight of the F-16 (USA's light fighter), but can carry as much load as an F-15 (their heavy fighter), while still being more agile than both. Technology has developed. That is also why the EF and rafale were selected over the F-teens, because of the newer, improved, advanced airframe. It is not just in computers that technology keeps advancing. Why is it that a single microprocessor today can do the work that took hundreds of microprocessors just two decades back, while still being cheaper and less power hungry than earlier gen microprocessors?

New rafale emp wt is 10.2-10.5tn
|
It can carry only 6.5 ordinance.
|
su30 mki carry 1.5tn more ordinance with extra range.
|
Flight time-rafale 2 hrs and su30 mki-3.5 hrs

You are talking about Rafale M which is a Naval version...and Naval version are always havier then Normal version..

Secondly it will be a pure waste of fighter like Rafale if it can carry 6.5 Tonne of ordinance Only...So if not more the minimum ordinance carrying capacity of Rafale will be around 8 Tonne....
