UAV Panchi Warms Up for Maiden Flight

[Kinetic]

Low cost???

 

[khujliwal]

Certainly not.

keyaan ahyo baba ???

firstclass saain, tavi chao. sab naala patent kare vetha aayo asa je laye kuch ta chado?

 

[Nova2]

But Baaz is a Pakistani UAV.

Well in that case i take back my words of Bazz being a cool word

 

[volatile]

Please share some spec as it seems to be base line UAV

 

[kurup]

can it kill like american predator and reaper? if not, its just a toy.

It's not an armed variant .

Please share some spec as it seems to be base line UAV

"Panchi" hahaha. what about "Baaz" "Cheel" or something

Or how about 'Totaa', 'Mainaa' or 'Kauwaa' instead........
Very unimaginative name this 'Panchi' is !!!!

Who cares about the name. I am actually more interested about the powerplant.

According to a site, here are the specs for the powerplant.

"VRDE had developed light weight, high specific power output engines for UAV application. These include two stroke single cylinder, twin cylinder and four cylinder engines, based on a modular concept.

Features
* High power to weight ratio
* Gelnisil/Hard chrome plated aluminium cylinders
* Multi-piece crankshaft technology
* Diaphragm type carburetors for all position operation suitable for aerial as well as ground applications
* Single-cylinder engine (RE-1-11-P) develops 11 hp and weighs 7.5 kg
* Twin-cylinder engine (RE-2-21-P) develops 21 hp and weighs 10.5 kg
* Four-cylinder engine (RE-4-38-P) develops 38 hp and weighs 22 kg"

Panchi uses the twin or quad cylinder options. I am baffled why VRDE had to 'develop' an engine, when such two cylinder engines are a dime-a-dozen sold hamesha off-the-shelf and reverse engineering is an easy straightforward option. (Don't tell me about morals and copyright, that sh*t doesn't fly when it comes to defense matters.)

Why not develop one? You know engine is the most vital part of any vehicle, instead off buying something off the shelve and working around it, DRDO decided to make one 'Specifically' designed for the application on these UAVs.
Engines are also most maintenance heavy part, some of the criterion of the end user are -- low repair cost, 24X7 availability of technical support and complete operational efficiency. Do you think this can be fulfilled by any foreign engine?
The maintenance from software to hardware should come under one umbrella if they want to keep the turn around time of the UAV to its bare minimum.

The reasoning for my previous comment was that sometimes this 'wholly indigenous development' bit ends up costing far more money (some would say a humongous amount) than it really should - which is a particular phenomenon that got fashionable in India because of the Nehruvian 'self-sufficiency' movement.

I know it is still followed these days, but globalization has made this sort of thing obsolete. 'Indigenisation' and 'development' for the likes of small basic engines like the modular two stroke single, twin and four cylinder engine is IMHO hogwash because the basic designs of such engines are about half a century old. The basics of making them (hot-forging of crankcase parts, sintered powdered-metal casting as well as CAD/CAM micro-machining) are very straightforward and can be easily sourced in India. So what is being 'indigenised' and 'developed' anew? God only knows...

Honda and Subaru started making these sort of reliable boxer type two-stroke engines right after WWII. It would be interesting to see how much money has been spent by defense sector in India to 'develop' these basic items some seventy years later...

IMHO the Chinese approach is far more pragmatic. They choose a basic rotary or boxer engine (such as from the likes of say, ROTAX or CONTINENTAL). Then they find a way to cheaply and reliably duplicate it by changing the design and work the bugs out within a couple of years. Pretty soon customers end up buying Chinese products and not the Western Brands. Indian Govt. instead - spends several million dollars 'developing' this basic product from the ground up (akin to re-inventing the wheel) whose reliability is actually now questionable. Definitely not a model to follow.

The reason that this sort of thing is still fashionable in India is because it helps defense contractors and Govt. servants hide massive amounts of corruption and graft in the name of development (percolating all the way up to the very top). A lot of Indians will lap these things up in the name of Patriotism and 'Deshprem'. And leave it to the RSS and Shivsena types who are fanning these flames to support the defense contractors and military- industrial complex in order to drive up defense purchases (and the graft with it).

Case in point is the LCA programme, and in particular the Kaveri turbofan engine project for the LCA which has been continuing for at least a couple of decades in 'slow bake' mode. By the time 'development' completes, the Kaveri will be obsolete as a product, and the cycle will again start with another 'development' item.

Im not from an engineering background, but are you sure these engines are interchangeable between a moped and a UAV?

And as you said these engines are from last century, they can be easily made. Even labs in IIT can make them, so I don't think much money could have been invested in making this one, you can gauze it from the fact that VRDE haven't publicized the development of this engine much, other than some brochures.

Why do you think India doesn't reverse engineer anything, just ask this to any pakistani member here, they think whole of India's missile and space program is reverse engineered.

RSS and Shiv sena never comment on defense related topics, now you are just sensationalizing the topic at hand.

Kaveri is all together a different ball game. Comparing that to this is like comparing apples and oranges.

To sum it all, this is relative simple engine to make without a need to spend much money on its development. And in house product gives the army advantage in getting its hands of the spare parts and consumables like lubes more easily and will cost relatively less, further decreasing the life cycle cost of operating and maintaining these UAVs.

Here is another achievement of VRDE - Indigenous Rotary Engine tested successfully on Nishant UAV
Refer this for more DRDO-VRDE - Engine Developments for UAVs

It seems that Rustom 1 & 2 will have indigenous engines as well

Moreover it is unlikely that the final variant will be less than 2100 Kgs. With that figure in mind and typical margins for capability growth, DRDO has decided to fit the Rustom-2 with new diesel engines.

As such the two existing 125 HP Rotax 914 engines (one on each wing) are slated to be replaced by new 200 HP class diesel engines supplied by Lycoming. Interestingly, the new engine configuration is slated to be indigenized with a domestically developed equivalent as a result of a collaborative effort between DRDO's Vehicle Research and Development Establishment (VRDE) and Tech Mahindra
