A new solar high altitude long endurance (HALE) UAV is in the works. Prismatic and B.A.E Systems are working closely on developing the UAV known as PHASA-35. PHASA-35 will offer low cost year round surveillance and vital communications in remote areas.
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-metre wingspan and weighs just 150kg – 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.
