Passive solar thermal storage heating
Thermal mass of any kind can by definition be called a thermal battery, as it has the ability to store heat. In the context of a house, that means dense materials like bricks, masonry and concrete. Even a jug of water sitting in a sunny window is a thermal battery of sorts as it captures and later releases heat from the sun. A. . Taking advantage of a 'phase change' raises the bar a bit - stick with me, it will be fun, I promise :) A significant input of energy is required to cause a material to change from a solid to liquid. That energy is later released when that. . If you had a heat-collecting solar panel (directly heating air or liquid rather than generating power with photovoltaics), you can use that to charge your thermal battery. Envision this -. . If you take solid paraffin (heat capacity Cp = 2.5 kJ/kg·K and heat of fusion of 210 kJ/kg), let's say 1 kg, at room temperature, you will need 2.5 kJ. [pdf]

Solar bracket driver design
The development of the Bi-Axial Solar Array Drive Mechanism (BSADM) presented in this paper is a demonstration of SSTL’s innovation and pragmatic approach to spacecraft systems engineering and rapid development duration. The BSADM (Fig. 1) is designed to orient a solar array wing towards the sun, using its first. . Surrey Satellite Technology Ltd (SSTL) is a key supplier of small satellites based near London (United Kingdom) providing complete in-house design, manufacture, launch and operation of. . pin-carrier mounted on hinge shaft pin against stop on static housing . Under conventional circumstances, without damping, the solar array wing used for the SSTL satellite would bounce back after deployment, and come to a rest at an unknown position. A back-driving torque of 50Nm is needed. . The track axis shaft is mainly supported by its front duplex bearing. These bearings will take most of the axial and radial loads during launch. An additional single row bearing has been implemented at the rear end of the slip ring to. [pdf]
