BAE systems' solar aircraft completes pivotal 24‑hour flight
A team of British engineers leading the PHASA-35 unmanned aircraft project, developed by BAE Systems, has achieved a significant milestone in the advancement of stratospheric technology. The company has successfully completed a crucial test of the aircraft.
Recent trials conducted at Spaceport America in New Mexico, USA, demonstrated that the solar-powered aircraft can remain airborne for 24 hours at an altitude exceeding 12 miles. BAE Systems highlights that this enables rapid preparation for subsequent flights within just two days.
An aircraft powered by solar energy
The PHASA-35, boasting a wingspan of 115 feet, was tested to verify its flight, landing capabilities, and rapid mission reconfiguration. Designed by Prismatic Ltd, a subsidiary of BAE Systems, the aircraft can operate above standard air traffic and meteorological conditions, making it ideal for long-term reconnaissance and observation missions.
Bob Davidson, President of Prismatic, emphasised that the recent tests confirmed the PHASA-35's ability to perform its intended tasks, marking a major accomplishment for the team. The goal is to have the system operational by 2026. One of the recent tests involved utilising a software-defined radio as a reconnaissance sensor, which had a considerably heavier payload than before.
Even better performance in 2025
The team responsible for the PHASA-35, based at the British Prismatic facility in Alton, plans to deliver an enhanced model of the system by the end of the year. The new model is anticipated to significantly improve the solar efficiency and energy storage capacity, paving the way for more efficient missions in 2025.
Prismatic is part of FalconWorks, BAE Systems' research and development arm within the aviation sector. Dave Holmes from FalconWorks highlights that collaboration with various BAE Systems departments and industry partners has contributed to the success of the recent tests, demonstrating the system’s reliability for operational use. The team intends to utilise data from these tests for further optimisation of the technology.
