MMA Part #17A-42
Our innovative HaWK solar array is a high-performance, 42-Watt solar array system for the CubeSat class spacecraft. The system consists of two array wings (center panel with 2 flip-out panels per wing), launch restraint mechanism and single-axis pancake solar array drive assembly (SADA*) for improved orbital average power (OAP). The HaWK array wings are designed to interface in both a gimbal or a non-gimbaled configuration without interface/configuration changes. The complete array system is stowed for launch and released after power is applied to a melt rod release mechanism. Deployment of the flip-out panels and wings is accomplished using stored energy provided by springs. If the mission requires, the sun-tracking single-axis SADA is used to track the sun’s position and provide maximum orbital average power (OAP). The HaWK solar array was developed under Air Force Research Laboratory (AFRL) funding.
In 2017, the HaWK achieved flight heritage, and a similar version of HaWK is flying on the interplanetary mission, MarCO.
