MMA Part # 27L-50B
MMA Design’s innovative approach to this solar array design offers lower system mass and reduces overall system technical risk. Our patent-pending thin-panel design is an efficient solar array structure that will achieve a specific power greater than 85 Watts/kilogram (W/kg). The array provides outward facing cells when stowed so that power can be generated before array deployment.
Higher performance can be achieved at overall lower system cost and significantly lower technical risk with our composite thin panel technology. The stowed panels will fit on the 3U x 2U face of the spacecraft and contain strung CIC’s on both sides of the panels.
The single stowed thin panel of each wing will be launch restrained by an aluminum release bar and a centrally located flight qualified thermal knife similar to our current HaWK and eHaWK solar arrays. A single thermal knife is required for each of the two stowed wings. The launch restraint structure will incorporate features to support the preloaded solar array panel under launch loads. This design gained flight heritage in November 2017.
