What exactly is wrong with Tapas that makes its operational effectiveness bad? What blunder? As far as I see, there is no way of getting lower weight with the SAR AESA radar, sensors embedded in it. The empty weight includes all of these. So, the additional payload is only for arms and missiles.

I see that the thrust to weight ratio of Predator MQ1 as 115HP/1020kg at MToW and for Tapas at 360HP/3200kg at MToW. The TWR is same for both. The fuel ratio of MQ1 predator to Tapas is 300/1000 kg which is also 30% of their weights. I see nothing wrong in Tapas to make it a blunder.

Who gave you these kind of false stories? If the drone was to be rejected, why would they showcase the engines in Defexpo?

Am not saying it get ,rejected it may see limited number in service but the real tapas is meant be a UAV and ucav config but as of current state it's wing loading can't be done that easily also it need sginificant weight reduction, as told before duel engine create more darg than single engine thus it also effect the endurance and increase the internal fuel consumption,but the real deal is single engine twin boom UAV which is better in allspects and it may or may not do little more than medium to high altitude flying (am not sure abt this)

How about the info coming from none other than Director of Rustom project?

Why do u have so much confidence in your own ignorance?

You fanboys think that if u have an engine stuck to a pole, it’ll fly and nothing else matters - there’s no need for aerodynamic design???

Acc to drdo in the recent Press conference, they say they gonna offer rustom 2 next year to armed forces, they are currently doing all the payload tests that will be completed by this year.

Listen to the lecture Rustom’s project director gave during the last AeroIndia.
The realization of design flaws in coming from Rustom team itself!!!!

I like people who ask nicely (instead of rudely/ignorantly challenging)

Here’s the video (the detail I mentioned should be somewhere in the lecture). He gave the same lecture at few venues, with same details but in slightly different order (I didn’t relisten to it to tell u the exact time in the lecture)

Ah! Thought the question was for me.
Anyways, enjoy the video if you care.

This was after the first flight in 2016. Has there been any new updates about weight reduction afterwards? First flight is generally the most conservative design and only later will the redesign happen to get optimal design.

This the press conference of DRDO, probably in first video, it is said about Rustom as well as AMCA.

Yeah, put more stupid arguments to hide your ignorance. They used new engine because they failed to reduce weight.

Isn't India developing a stealth UCAV AURA next?

Its a paper plane just like AMCA.

Indian record in developing UAVs has been abysmal so far.

They failed to reduce weight as there was a need for more equipments to be fitted. There is no point making a Rustom-1 drone or copying Heron drone to get a 1ton MToW drone with minimal capability

Oh..boy you are a professional BS maker.

1.8 ton is the designed weight with all services requirements. They failed to make it not withstanding 3-4 years of delay in first flight.

No one is copying anyone. From US to Turkey all have <2 ton UAV with primary surveillance role. Rustom-1 was a TP program to the ultimate goal of Rustom-2.

Just look at the video posted by enquirer. The all up weight (AUW) or MToW was designed to be 1800kg but the AUW is now 1000kg more. Hence, twin engine of 180hp each is used. The AUW is now 3tons with 1.8ton empty, payload of 300-400kg and fuel of 900kg.

Rustom 1 is also a fit drone and is capable of being used in surveillance operation. It has undergone over 15 flight tests by 2015 and was said to be good enough for use.

Rustom 1 and Rustom 2 are different category drones. Rustom-1 is a category similar to Heron whereas Rustom 2 is a heavier and more powerful drone. India uses the light drone Heron and Rustom-1 is the perfect substitute for it. The Rustom-2 is a new drone, different from Rustom-1. Hence the name has been changed to TAPAS, to show that it is not just an upgradation of Rustom-1

Are you illiterate or playing stupid? Cant understand a simple talk?

He said the designed weight is 1,800kg but the first prototype is 2,800kg. They are expecting to reduce 280kg.

They failed at initial estimation so they changed engine. As simple as that.

You need to learn basics of different categorises of UAVs. Heron is not equal to Rustom-1. There is a reason no one ordering it.

Yes, that is what I said. All-Up-Weight means MToW in general. So, 2800kg is the new MToW, not empty weight. You were confused about estimated total weight and empty weight.

Can you explain what is the difference? If anything, Heron has service ceiling of 10000m and may be inferior.

You brought in empty weight to confuse other (yourself) as usual . From start itself i was talking about MTOW.

Heron has a payload of 250kg. can Rustom-1 even carry 100kg?

Systems comparable to Rustom-2 are TAI Anka and MQ-1C. Twin engine was a wrong design choice. The program director even said next UAV would have single engine and twin boom.

Next we should go for 4-5 ton MQ-9 like UAVs.

 

[Kshithij]

Heron is unarmed. The payload is the additional sensors. Yes, Rustom-1 can have the additional sensors too. Rustom-1 did carry 2 Helina which meant that its payload should have been at least 100kg.

Systems comparable to Rustom-2 are TAI Anka and MQ-1C. Twin engine was a wrong design choice. The program director even said next UAV would have single engine and twin boom.

Next we should go for 4-5 ton MQ-9 like UAVs.

MQ1C has MToW of 1650kg and has 165HP engine. TAI Anka also is similar in MToW and engine power. Tapas has 2 engines of 180HP and MToW of 3tonnes. It is bigger than MQ1C. TAI Anka is inferior to Tapas. Tapas has SAR radar and many other electro-optical sensor to do much more powerful surveillance.

The next 4-5 ton UAV is AURA. The only reason to have a heavy UAV is to carry heavy ammunition and not surveillance. Surveillance can be done by lighter UAVs. So, the best bet for heavy UAV is AURA with non-afterburning Kaveri engine. I don't see a reason to go for MQ9 drones
