India Advances in Aerospace with Successful Test of Solar UAV

Summary: India’s National Aerospace Laboratories (NAL) in Bengaluru has made a significant leap in aerospace technology with the successful test flight of a solar-powered High-Altitude Pseudo Satellite (HAPS), marking a step towards enhanced surveillance capabilities, especially along the country’s borders. Demonstrating sustainable flight at high altitudes, this breakthrough could lead to more cost-effective alternatives to traditional satellites.

India is positioning itself among the pioneers of advanced aerospace technologies with the recent accomplishment by the National Aerospace Laboratories (NAL) based in Bengaluru. They have successfully conducted a test flight of a solar-powered unmanned aerial vehicle (UAV), classified as a High-Altitude Pseudo Satellite (HAPS). This UAV is designed to operate at altitudes of 18-20 kilometers, surpassing the flight levels of commercial aircraft and potentially remaining airborne for extended durations, thanks to its solar power generation system.

The HAPS platform, still under development, could drastically reduce operating costs compared to satellites due to its independence from rocket launches. Last week’s test in Chitradurga district’s Challekere testing range witnessed the UAV, weighing 23 kg with a 12 meters wingspan, soaring for approximately eight to nine hours.

Director Abhay Anant Pashilkar of NAL, under the Council of Scientific Industrial Research (CSIR), expressed the importance of this milestone and outlined the subsequent targets that include a continuous 24-hour test flight to fully evaluate the solar power generation and storage system. Prospects for operational deployment are aimed for 2027.

Additionally, solar-powered UAVs are gaining attention worldwide as they offer persistent surveillance capabilities, a factor that came to the forefront following the 2017 Doklam Standoff. Unlike battery-powered UAVs which have limitations in both flight duration and area coverage, and satellites that constantly move in orbit, HAPS offers a stable and long-term monitoring solution. The prototype tested is a smaller model of the envisaged aircraft, and future production will rely on industrial partnerships.

The development of this technology also opens doors for disaster management support and the provision of communication networks in remote or calamity-stricken regions. Several countries like China, South Korea, and the UK are also exploring this technology, alongside India’s engagement with private sector companies through initiatives like the Ministry of Defence’s iDEX. NAL’s strides in R&D hint at a future where pseudo-satellites could undertake roles traditionally fulfilled by satellites, enhancing humanity’s capability in both security and humanitarian missions.

FAQ – National Aerospace Laboratories’ Solar-Powered High-Altitude Pseudo Satellite (HAPS)

1. What is the National Aerospace Laboratories (NAL)?
NAL is an Indian research institution based in Bengaluru, specializing in aerospace technologies. Part of the Council of Scientific Industrial Research (CSIR), it conducts advanced research, design and development in the field of aerospace.

2. What has NAL achieved recently?
NAL has successfully conducted a test flight of a solar-powered unmanned aerial vehicle (UAV), classified as a High-Altitude Pseudo Satellite (HAPS), enhancing India’s surveillance capabilities and taking a step towards cost-effective alternatives to traditional satellites.

3. What is a High-Altitude Pseudo Satellite (HAPS)?
A HAPS is a type of UAV designed to operate at high altitudes, between 18-20 kilometers above the Earth’s surface, meant to remain in a quasi-stationary position and provide services similar to a satellite but closer to the ground.

4. Why is the HAPS platform significant?
The HAPS platform is significant for its potential to offer extended duration flights without the need for rocket launches, reducing operating costs. It can also provide stable and long-term monitoring for surveillance, disaster management, and communication networks.

5. What are the advantages of the tested UAV?
The solar-powered UAV demonstrated in the test can potentially stay airborne for extended durations due to its solar power generation system, surpassing the limitations of battery-powered UAVs and the constant motion of traditional satellites.

6. What was the outcome of the recent test?
The recent test saw the UAV, with a 23 kg weight and 12 meters wingspan, fly for 8-9 hours. There are plans for a 24-hour test flight to evaluate its solar power generation and storage system.

7. When is operational deployment expected?
Operational deployment of NAL’s HAPS is aimed for 2027.

8. How do solar-powered UAVs compare to battery-powered ones?
Solar-powered UAVs can potentially remain airborne for much longer periods, providing persistent surveillance and a wider area of coverage than battery-powered UAVs, which have limited flight duration and coverage area.

9. Are other countries researching HAPS technology?
Yes, countries like China, South Korea, the UK, and private sector companies, some in collaboration with Indian initiatives like iDEX under the Ministry of Defence, are also exploring this technology.
