The final stage of preparing for the next flight test of PHASA-35 is complete – 72 hour soak test including operation with UK MOD communications payload.
PHASA-35 has successfully completed the critical 72 hour soak test, which saw the aircraft operate for 72 hours in a simulated environment that models the harsh stratospheric conditions in which the aircraft is designed to operate. These ‘soak tests’ demonstrate that the aircraft working effectively as a fully integrated system together with Dstl’s payload.
In addition, the tests allowed the team to practice various operations that would be performed during flight, such as transition from daytime, when the craft is powered by the solar array, to night time when the aircrafts batteries are discharged. This was part of a programme of training activities building experience for operating the craft, more news to follow soon.
The trials, a collaborative effort by Prismatic, BAE Systems and the UK’s Defence Science and Technology Laboratory (Dstl), advancing the aircraft’s operational utility.
