This paper describes calculation and research of aerodynamic six component internal strain gage balance aerodynamic drag component design. The main problem of aerodynamic research is clear result receiving from each component and prevention of interference from other components. Methods used in this research are FEA and parametric design. During research was found drag element zone, where is not influence from the lift force. Before a balance can be designed, the specification of the load ranges and the available space for the balance are required. This is a challenging step prior to the design of a balance since cost and accuracy consideration should be made long before the first test are performed. The maximum combined loads specify the load ranges for the balance design. The maximum design loads of a balance are defined in various manners. During developing time of the strain gage balance the main problem was axial force element design. This is the most complicated element. Using modern calculating methods with powerful software there developing of such elements can be produces with high accuracy and minimal costs. Design what is described in this paper have such pluses as, low or zero interference from the lift force and easy to be manufactured.
