| Abstract: | The temperature self-compensation of aerodynamic bal-ance foil strain gages is described.The influence of strain gage opera-tive characterizations and bonded technology on measuring accuracyand stability of aerodynamic balance is discassed.The temperature com-pensation of strain gage thermal outpat and balance meterial elasticmodule are necessary in order to increase measuring accuray and sta-bility of aerodynamic balance. |
