Thermalling sailplane turn indicator

Image Number 2 for United States Patent #4506847.

A thermal indicator with a sensor (28) mounted over the wing stubs (12, 13) of a sailplane to detect relative movement therebetween due to bending moments applied to the wings on meeting a thermal and a processor of the sensor signals to generate signals indicative of the direction to be turned to enter the thermal. The processor signals are suitably displayed to indicate thermal strength, and left or right directions to enter the thermal.
