Abstract

A simplified algorithm of flexible curve-curve high constraint between the convergence skeleton and the A8 roller is proposed. Based on this algorithm and the Craig-Bampton modal synthesis method, a rigid-flexible coupled dynamics model of the Axisymmetric Vectoring Exhaust Nozzle (AVEN) is constructed. The equivalent simplification and real-time loading of the thermal aerodynamic loads are then realized according to the superposition principle and energy equivalence principle. The error between the calculation result based on this algorithm and the experiment is about 4%, showing high credibility. The comparison of simulation results between the model using this algorithm and the model using contacts show that the former was more stable and more efficient with the same precision. It could reduce the simulation cost of a single case from three days to half an hour. Aiming at the two typical states of AVEN, we compare the contributions of the flexibility of key components to the deflection efficiency. The results indicate that flexibility of A9 ring is the main influencing factor of the deflection efficiency, accounting for up to 94%. It is shown that the rigid-flexible coupling model only considering the flexibility of A9 ring would be a more efficient and rapid estimation method for the deflection efficiency simulation of AVEN.

Key words： axisymmetric vectoring exhaust nozzle; flexible curve-curve high constraint; rigid-flexible coupling dynamics; deflection efficiency; thermal aerodynamic load
