Design and simulation of morphing nose cone for umbrella guide-rod mechanism
摘要
Abstract
The morphing nose cone for aerospace vehicle will provide a novel way for improving aero-dynamic performance of reentry vehicle.In order to realize adaptability of the aerospace vehicle to the complex environment,a morphing nose cone of aerospace vehicle was presented by using a series of umbrella guide-rod mechanisms,and its kinematic characteristics and system stability were analyzed. Kinematic simulation analysis of the morphing nose cone under different driving modes was carried out to find out the influence of the main factors on its operation performance and system stability.Simula-tion results showed that the elongation and the deflection of the morphing nose cone were 1 499.6 mm and 500.7 mm,respectively,which meet the requirements of design.Comparing with driving mode of the constant speed,driving mode of the sinusoidal motion can makes the morphing nose cone running more stable.关键词
