Wind tunnel testing is also computer controlled and aided to understand even minute changes. In addition, 3D printing of parts enable in understanding aerodynamics and many models can be made to find the most optimal ones for use. Simulation does not mean jut mathematical calculation. Even the...

Nothing can be done if politics is bad. Congress sabotaged everything and hence nothing could be done.

That is what I pointed out - Su30 MKI was not delayed despite Indian request to add canards So, you understand that canard addition does not necessarily cause delays? It requires bright minds, not large amount of natural resource to get R&D done. India has the basic infrastructure needed to...

Do you know how much the computation power has increased? This alone is enough to overcome all the problem with manual calculations. Also, Russia got canards on insistence of India which was funding the project. The first funding of India started in 1994-5 and Su30 going into production by 2000...

This is because delta wing has high landing speed and hence is dangerous on a carrier. So, we will be getting the tail stabiliser to slow it down. It is quite a reasonable modification

Your second image is incompatible with the first. There are no tails in the second image

Adding canard is not a big modifications. We have seen how our Su30 MKI was added a canard and yet it entered service quickly. Also, the power of computation has increased massively in the meantime. Even the processor on planes have improved to 180nm - 90nm lithography (India only has upto...

MEF will have 3.3 ton of fuel. Source is livefist interview during AeroIndia

MiG21 didn't have composites. Bit composites are only 33% weight saving compared to aluminum. 60% of Tejas airframe is composite which reduces weight by 20%. But the weight of a plane comes from various other parts like internal LRU, fuel tank etc which are not composites. So, Mig21 with such...

There can be very little weight reduction. One has to be realistic about weight. Even Mig21 with small size weighed 5.8ton. One can't simply reduce weight jist like that. So, even MWF will have higher weight according to its size increase and equipment addition.

Don't change the topic. You were trying to say that Tejas Mk1A and MK2 would take lot of time as design testing is lengthy. Whereas I am saying that more than physical design, it is the Integration of software that takes the most amount of time. Hence with the software integration already...

Can you tell me which weapon was used in Rudra? Except for cannon and Mistral ,Rudra had very limited weapons. The integration was done by France and they would not give the codes. Entire Rudra as well as LCH had to be developed indigenous systems. That took time. The FBW has to change...

Do you understand that ALH is just a transport chopper? ALH Rudra was just under development and not yet completed back then. You are missing the most important factor - software. Software is not easy to make. Making the flight controls, fire control, missile integration etc take time. ALH...

How much experience did HAL have in making helicopters? Also, the LCH helicopter was able to fly in 3 years. It was other factors like lack of softwares for combat role, lack of sensors, lack of missiles & integration and moat important, sabotage by UPA government which is responsible for delay...

The DRDO poster on MWF (someone posted above) shows that MToW (all up weight) is 17.5 tons. That is 4 tons over Tejas MK1 MToW at 13.5tons. This means that the improvement is 400/13.5 percent or close to 30%. Whatever aerodynamic improvement may have taken place, the improvements is likely to...

AMCA and Tejas MK2 will use same engine. That is why the MTOW of Tejas Mk2 is 17tons. How an it jump from 13.5tons in MK1 to 17 tons in MK2? That is over 20% jump. It is possible only if the engine also saw over 20% jump in thrust. So, 55/85kN engine will have to become 70/105kN. The same thrust...

3300kg is what was said, not litres. This is from livefist interview. The old Tejas had 2450kg

It is important that the development of the plane is completed at the earliest. Hence they will not wait for Kaveri but integrate it later after the flight trials in F414 is complete. The question is whether Kaveri is complete or not. And also whether it will be flying in Tejas MK1 or not

First, the EFT, Rafale etc are not top fighters. They are equivalent to Su30 but with slightly different roles. Tejas MK2 is 4.5 generation plane for mass manufacturing and not like AMCA. Tejas is made especially easy to be manufactured by having less fasteners, jigless body, composites parts...

The IRST generally pokes out with a big camera like lens structure. It can be adjusted near radome or somewhere in fuselage as large part of it protrudes outside and little space is needed in inside. There is also something called EQPT BAY (equipment bay?) below canopy. What is that for?
