That's another swarming drone they are developing.

That SARPA one? That doesn’t seem to be a swarm drone, but more of a MALE UAV.

Hmmm...
@porky_kicker

So Bangalore based NS Aerospace happens to be working on a UAV... (This pic is of US Airforce personnel testing their ACID (Air Combat Intelligence Development) system).

Is it written SARPA?

NewSpace is a Noida based company. One of its founder was also a Co founder of Team Indus. So they at least have some experience in aerospace. Their main focus is AI so I am not even sure if they will even make anything more than a prototype for testing their software.

You mean Comparing UTTAM with Chinese radars? As Porkis don’t have their own radars, they just do papa papa I need radars, and their papa china gives them.


UTTAM GaN will be a total devastation for our adversaries.

Yes the TFR modules max range etc
Is Thier any comprehensive list ?

How do I explain this...

Consider it as a feedback force generated artificially.

If you drive a car with say a drive by wire ( analogue of fly by wire in aircrafts ) , while using the steering wheel you will not encounter resistance ( no feedback ) . In a normal car you need to forcefully turn the steering wheel and it resists and as you get used to it , you get a feel as to how much you should turn the wheel to steer the car around a corner etc.

This artificial feel needs to generated on the control stick of aircrafts with FBW because the aircraft is not being perse flown directly by the pilot. The pilots needs to have a feel that the aircraft is responding to he control stick inputs.

Roll and pitch are the axis around which a aircraft turns.

The example you gave regarding Cars, is called "assist" while steering. In an EPAS (Electronic Power Assist Steering System) or simply EPS there is a DC brushless motor which provides the assist according to the input driver torque, that why, while maneuvering or steering, the driver feels almost no force (very little the force due to the geometry of the vehicle or the friction point between the wheel and the road) in EPS enabled cars, which is not in the case of traditional, vintage hydraulic system.

Drive by wire in passengers vehicle is comparatively newer concept as compare to aviation industry and only being implemented in electric veh, sedans or small suvs. In Steer / Drive by wire system the rack and pinion of a steering system would be replaced by ECUs (Electronic control unit), the main advantage of this system is it will make the system lighter (due to removal of wirings) easier to maintain (same concept as LRUs) and can support other level 3 or higher ADAS (Automatic Driving Assistance System) autonomy. The closed loop response and feel is more or less same (better in some cases) as EPAS.

Now regarding aircraft I think as they have to bear the roll and pitch movement, they have to bear more G-force as compare to only an Yaw maneuver in cars (that's why cars face only less than 1 g even in very challenging and difficult maneuver). Maybe that's why you need a feel force.

Thank you sirji

What update ?

It's already operational in ships since long.

No I mean what interchangeability has been noted?.. The UVLS takes in Brahmos & what others?

Kaliber and likely nirbhay in future....it isnt really a true UVLS...which is a shame

OFB Light tank or Artillery?, also posted in the Light Tanks for Indian Army thread.

That's a mobile light arty... The light tank had 105mm gun too, but looked different.

The OFB propsed BMP based light tank with 105 mm gun (GIAT turret) with additional ERA/NERA cover, as well as 105 mm SPH makes sense for Para-Airborne forces, if weight can be kept down to below 20 tons which can be deployed by current OFB parachutes. Also, since BMP-2s are amphibious, they can also be deployed in amphibious assault roles.

Many old BMPs can be converted in this regard.

They had already proposed one in 90s or 2000s I remember but army didn't bit it and instead issued an rfi for 200 tracked and 100 wheeled and it also was shelfed

They proposed it for regular army, which was rejected.

But for Para airborne, these tanks and SPH might be an attractive option, especially if old BMP vehicles are re-purposed in this role.

Yep.. for the Strike Corps.. Now with 1 corps being converted to Mountain warfare.. Hope we order these light tanks and sphs weighing around 18 tons, which can be air dropped.. and also more c-130s for dropping them..

 

[Marliii]

DRDO is already developing a light tank for the army better go with that one

 

[shuvo@y2k10]

The new DRDO Light tank might be 30-35 tons to match the Chinese Type 15. It will be powered by 1000 hp engine.

Most likely, that won't have the capability to be depolyed by parachute, or be amphibious.

I hope stupid army will not reject it this time.

Yup even the american next light tank whose competition is now ongoing both the participants weight are 25 to 35t

We also need air droppable 20 ton tanks like sprut. which can be air dropped into remote areas along LAC..
