Any chance you took a pic of the TAMP info board?

You mean the one behind the model on my pic? Not particularly, though I have a higher res pic, so might be to zoom in. Let me take a look at it over the weekend...

in the interest of seeding the tech, DRDO could open src to indian OEMs the tech it had developed for the nishant UAV. most of these are tactical short duration types so very high security and robustness are not a hard requirement.

Many Indian OEMs are (I am told) import and assemble by screwdriver given that no one in India makes most of the stuff. The motors are imported, the EO units are imported, the avionics to communicate with te UAV are imported. I think even the propeller blades are imported. If everything can be done here - I would excuse the use of locally made aluminium pipes.

Here is a close up of the power unit of a "locally built" UAV. Make in India will be like this - I am Ok with that as long as people get jobs. But DRDO labs will have to develop critical tech even if local built off the shelf stuff looks ugly

I think that octacopter is off the shelf.

VRDE and Tech Mahindra were jointly developing 200hp class aerodiesel engine for Rustom 2 UAV.

Other forums report that the project has been canceled. Anyone has any leads on this?

I wonder why all engine development projects are squashed in Desh. Beyond initial announcement, nothing heard of the Bharat Powerpack for Arjun Tank either!

The Rotary UAV project based on the Chetak is becoming more clear. HAL's ARDC is the lead design agency. ADE is collaborating. HAL has now issued an EOI for RISK SHARING PARTNERSHIP FOR DEVELOPMENT OF RUAV.

Basically, it is looking for an experienced partner for development of Automatic Flight Control System.

While conversion of a manned aircraft to an UAV is not ideal, it is definitely a start. The airframe is proven and HAL must have lots of data on the flight characteristics.

The Israeli VTOL air ambulance in news, its data sheet talks about two 1.8m rotors lifting some 1500kg, if they are arranged as contra rotating rotors, they could lift as much, be it a chopper airframe or a vertically aligned Nirbhay sized airframe

As a tech progression they could move from chetak to Ka-226 to miniaturization leading to swarm strategies deployed from a Naval ship

Japan's Mazda has a >400hp Wankel engine for automobile applications

I somehow like the muscular KTM Duke look though.

From DRDO Chief Interview

What is the update on the UAV programme?


Design of Unmanned Combat Air Vehicle (UCAV) Ghatak is coming up very well. The dry engine of the Kaveri will power Ghatak. The second aspect is stealth. If you look at the shaping of the existing UCAV like B2 it is designed in such a way that it deflects the energy and can remain undetected. The coating on the UCAV only amounts to 20 per cent of the stealth.

I have given ADA time till April to produce a life-size model of UCAV (fully metallic, without any coating for RCS reduction) and measure its RCS (Radar Cross Section) to understand its detection range. RCS reduction and painting will simultaneously proceed thereafter. As far as the electronics part is concerned, if all payloads of Rustom UAV are certified, we will use them as it is in Ghatak programme. We will know the acceptance on the Rustom payloads by next year
