After combat drones, India eyes solar-powered UAVs capable of flying for a fortnight.

After launching development of stealth UCAVs (unmanned combat aerial vehicles), India is now also looking at designing solar-powered spy drones which can cruise in the sky for several days at a time.

The high-altitude, long endurance (HALE) solar-powered UAV will not just reduce Indian military's carbon footprint but more importantly provide a cost-effective and flexible 24x7 ISTAR (intelligence, surveillance, target acquisition and reconnaissance) platform akin to "a pseudo-satellite" orbiting closer to the ground.

Yes, Army and IAF have asked us to develop the solar-powered HALE UAV. Initial work is in progress for such a drone which can undertake a 15-day continuous flight over 30,000-feet," DRDO's chief controller R&D (aeronautics) Dr Prahlada.

The drone will harvest solar energy during the day, storing it in fuel cells to provide power for electric motors for night flying. "Solar efficiency is low but we are looking at a payload of around 50 kg (sensors, cameras etc). We will seek some collaboration from either US or European companies," said Dr Prahlada.


This comes at a time when several international aviation majors are doing cutting-edge research on solar UAVs. Boeing, for instance, is developing a UAV with a 400-feet wingspan, called Solar Eagle, which can operate continuously for an astonishing five years. It is being described as a "zero-maintenance, launch-and-leave UAV".

With remotely-piloted spy as well as combat drones being seen as major force-multipliers or game-changers in modern-day warfare, DRDO has launched a series of UAV programmes for Indian armed forces, which have largely depended on Israeli drones like Searchers and Herons till now.

This includes the secretive AURA (autonomous unmanned research aircraft) programme to develop UCAVs capable of firing missiles, bombs and PGMs (precision-guided munitions).

The Cabinet Committee on Security has also now cleared a Rs 1,500 crore DRDO project to develop the Rustom-H MALE (medium-altitude, long-endurance) drone, capable of operating for 24 hours with a 350-kg payload. "Its first flight will take place in two years," said Dr Prahlada.

Then, of course, there is the smaller Rustom-I drone, with an 8-12 hour endurance and a 100-kg payload, as well as the already-developed Nishant UAV, which has a 4.5 hour endurance level.

Army, in fact, has projected a requirement of seven "troops" (akin to squadrons) of Rustom drones. As for Nishants, Dr Prahlada said, "Army has already inducted four such drones, which can be launched from hydro-pneumatic launchers without the need of runways, while eight more are being manufactured."

"Nishants can carry electro-optical, electronic intelligence and communication intelligence payloads. Since they can also be used for counter-insurgency operations, the home ministry has also expressed interest in seeing their operations," he added.

With DRDO working on the entire spectrum ranging from hand-held mini to full-fledged combat drones, a dedicated aeronautical test range from them is also coming up at Challakere, around 220 km from Bangalore. "It will be fully operational in two years," he said.

We should concentrate on solar powered autorickshahs...that would be a great benefit to our ppl....with regard to pollution and oil dependence.....I wish we thought more out of the box...

Boeing Solar Eagle....



All these developments are welcomed but we desperately need Rustom as clearly mentioned by the requirement of IA in the article....So i think its better these people start working....

I heard private companies were supposed to be involved in Rustom....any news on that ??/

Lots of UCAVs and UAVs from micro, mini to MALE and HALE are under development. But AURA is the thing we need most. Something like Neuron.

Thanx for the info....i knew the shortlisted firms but i didn't knew there were 23 firms....i just wanted to find out who won....Also i wanted to know whether tata was also on this list ??/

Well good news. Satellite solar power panels may work.
