BAE Systems and Prismatic Agree on Solar UAV Project — One Year Aloft is the Goal

A new, solar, electric unmanned aerial vehicle (UAV), which has the potential to fly for up to a year before needing maintenance, has become a step closer to reality following a new agreement between two cutting-edge British companies, BAE Systems and Prismatic.

Engineers from Prismatic and BAE Systems will collaborate on the development of the new solar powered High Altitude, Long Endurance (HALE) UAV known as PHASA-35™, with work already underway to prepare the first aircraft to be ready for flight tests in 2019.
The technology would offer a year-round, low cost persistent service for a wide range of needs including surveillance and vital communications to remote areas, using only the sun to power the aircraft during the day and recharge the batteries for overnight operation. Solar HALE vehicles offer a significantly cheaper alternative to conventional satellite technology, with PHASA-35™ (standing for Persistent High Altitude Solar Aircraft), being a concept solar electric UAV that uses proven, long life battery technology and ultra-lightweight solar cells to potentially maintain flight for up to 12 months.

The PHASA-35™ concept has a 35-meter wingspan and weighs just 150 kg. — its lightweight, efficient build allows it to fly at high altitudes for long periods of time. A quarter scale model (named PHASE-8™) completed a successful maiden flight in 2017, with Prismatic Ltd. and BAE Systems now looking to take the technology a step further.
BAE Systems will invest in the development and flight testing of the PHASA-35™ system as part of its drive to continually develop new technologies to support aircraft of the future, working collaboratively with SMEs and academia. Under the agreement with Prismatic, BAE Systems will provide expertise in aerospace technology and project management to progress the PHASA-35™ program through to a marketable offering.

Michael Christie, Strategy Director within BAE Systems’ Air sector, said that Prismatic is a fast paced and forward thinking company and PHASA-35™ is a great example of what the team can achieve in a short space of time. This program is part of the company's long term strategy to explore new technologies and solutions in air and space.
Paul Brooks, the Founder and Managing Director of Prismatic Ltd., added that PHASA-35™ has the ability to revolutionize the way all think about Beyond Line of Site (BLOS) communications. The team has worked tirelessly over the past two years to develop PHASA-35™ as a proven, cost effective and reliable system.
