And this is our own Warrior loyal wingman cumlow cost expendable drone .

I think they shud use Kalyani's recently developed engines rather buying them from outside. Any views??

@porky_kicker @Chinmoy @Karthi

Won't the topside air intakes cause the engines to suffocate in case of high-Alpha?

Nope , not sure about how the boundary layer behave but the designers are well aware of that and it can be avoided . This configuration is more stealthy and the main objective is Sead/dead so it makes sense. less drag also.

TEDBF looking super cool and it turned out to be the most beautiful Aircrafts if all time for me .

UAVs from Alpha and Adani

Note the MTOW. It's 26 tons. Rafale M has a max take off weight of 24.5 tons.

TEDBF will be larger than Rafale . Rafale has a length of 15.37 m and wingspan of 10.9 m . TEDBF is 16.3 m long and has a wingspan of 11.2 metres.

Is Mach 1.6 adequate when Mig 29 had much higher speed?

I think stealthy configuration, better payload and better BVR tech makes it better (mimus the speed)

excuse me, you say adani?

I think Mach 1.6 speed is acheivable via 98 KN GE 414 engine.

The speed will increase if you fit the under developement 110 KN engine.

Everything is great. But I still don't get the new shape of the elevons especially the leading edge straight part.

Don't u mean "stabilators"
Cause, elevons are what you have on tailless aircrafts, like the deltas

AMCA looks cool . Oozing too much sex appeal.



Thats a Storm Shadow class cruise missile on the inner most wing hardpoint.

Ehm, are you, really?

The second assembly line of Tejas was inaugurated by Sh Rajnath Singh today.

It's called LCA Tejas division plant II.

Can someone confirm whether the internal weapons bay of AMCA can hold 4 BVR missiles or 6 BVR missiles in Aerial combat config?
From the rear, it looks like a mox of Mig 29 and Su-57

4 as of what we last saw... It held 5 once. Not sure if they'll fit 6 later. Shouldn't be impossible

 

[Chinmoy]

Does inauguration here mean necessary equipment & tools are ready & Tejas airframe can start getting assembled or the production line will now start getting ready?

In short: When can we expect our Tejas production increase due to this new assembly line?

It means the production line is ready to roll out planes now.
But it would still require a couple of months more to get going in full stream.

Variable Buoyancy Systems for Underwater Operation

CAD model of VBS.

Developed VBS.

Integrated and detailed system architecture for various components of the VBS where 1 - Positive
displacement diaphragm pumps, 2 - flow measured sensor, 3 - solenoid valve, 4 - pressure relief valve, 5 - microcontroller, and 6 - water pressure sensor .


VBS can dive up to 60 m depth and has been designed to be directly installed in medium-size UVs. Simulation results show that the developed VBS can reduce up to 20 % of energy consumption
for each cycle (i.e. descending and ascending), in comparison to the same VBS being operated in standalone mode with either propeller or thruster for 60 m depth of operation.

Russia confirms work is going on for the joint development of the Brahmos-2 . Most probably a variant of Zicron.

Nobody clicked a picture of this Beauty .

Endure 15 Helicopter is a 15 kg class high endurance Rotary wing UAV designed to meet customized payload delivery requirements of our clients. The gasoline powered UAV offers unmatched performance to its users with an endurance of more than 2 hrs while carrying 4 kg payload at sea level. The UAV is equipped with a fully functional and robust Autopilot system which grants its pilot, the freedom to perform their tasks in fully or partially autonomous mode. The Autopilot system also includes multiple redundant fail-safe measures which makes it a reliable tool in critical applications. We, at EndureAir, strongly believe in customizability for end users, and hence the Endure 15 UAV offers a modular design capable of supporting different payload shapes and sizes.

How will the Indian Navy launch these? Ski Jumps will be enough?

Another thing, this HAL CATS needs to have a VLO drone with blended wing body design that can fly in the upper reaches of the stratosphere and act as a data relay and ISR asset. That way, we might not need to rely on SATCOM alone. I remember seeing a similar concept being studied by USAF too.

Be careful with us military doctrine in recent decades as some of them have failed spectacularly in all military wings.

Usa is almost starting to resemble Germany in WW2 with many zany ideas and most of them being impractical but differences are that they have rich and capable legacy aircraft.the Russians and chinese and are goin for more numbers and evolutionary approach in most weapon systems insted of revolutionary and path breaking technology except in some very few high profile cases like armata for example.
