In a significant step forward for the Indian aerospace sector, researchers at CSIR-National Aerospace Laboratories (NAL) have carried out a successful flight test for a new type of high-flying drone technology known as High Altitude Pseudo Satellite (HAPS). Unlike conventional drones, HAPS operates in the stratosphere, far above commercial flight paths, and is capable of remaining airborne for extended periods due to solar power and an advanced battery system. While the recently tested prototype is an early version of the envisioned system, it has already hit performance targets during its roughly eight-hour flight at 3 kilometers altitude.
The breakthrough flight test, conducted in Karnataka, highlights the potential of HAPS to revolutionize applications such as surveillance, communication, and terrain mapping. The ambitious project aims to create a fully operational HAPS with a wingspan comparable to a Boeing 737 by 2027. This larger version is anticipated to reach altitudes up to 23 kilometers and stay aloft for a minimum of 90 days uninterrupted.
Although still a work-in-progress, the unmanned aerial vehicle exhibits considerable design and engineering complexity. It employs a lightweight airframe and solar-cell films designed for sustained flight in the thin atmosphere of the stratosphere. The prototype’s success provides insightful data, especially concerning balance and stability amidst atmospheric forces, laying the groundwork for a larger, more robust craft. The director of CSIR-NAL, along with the program’s scientists, emphasize the importance of India developing its own advanced HAPS capabilities, given their wide range of potential uses.
CSIR-National Aerospace Laboratories (NAL) in India has successfully flight-tested a prototype High Altitude Pseudo Satellite (HAPS), a solar-powered, unmanned aerial vehicle poised to revolutionize long-duration flight applications such as surveillance and communications. Although the current prototype is a smaller-scale version, the project’s goals are set high with an ambitious vision for a craft that can match the wingspan of a Boeing 737 and remain airborne in the stratosphere for 90 days by 2027.
