Abstract
The thermal deformation of an edge-restrained plate is expressed as a deflection of the plate out of its plane. Where the plate is used as a reference plane, the deformation of the plate can be quantitatively monitored and compensated for. In the case of a radiantly heated plate, the temperature gradient adjacent an edge of the plate is a linear function of the plate deformation. With convective cooling, the temperature drop from an initial condition relates linearly to deformation. Consequently, relatively simple temperature measurements will provide the necessary information. The invention has particular application to the roof of a military tank turret that is used as a reference plane for a gun sighting system.
