A New Support Structure in Waverider Force Measurement
In this paper a new support structure was given to solve the problem met in the force measurement with engine jet.The force measurements of waverider were undertaken in the hypersonic wind tunnel.The test condition was at Ma=6, angle of attack α=-6°-6°, at which we researched the effects on the vehicle aerodynamics of inlet cowl opening and closing, support system, engine jet, and pressure ratios.To decrease the effects of strut on the jet flow-field, we took sharp belly strut to support the model in the wind tunnel.The belly strut could support the waverider model, force measurement balance, and it could make the inlet flow set up, and provide the high pressure jet.The test results showed that the belly sharp strut had little effects on the flowfield and could inject the inlet flow, and could provide very high quality jet.
