“…The state of the extended target includes dynamic and morphological variables, and there is a coupling relationship between them (Baum 2013;Liu et al 2022). For example, when a target generates maneuvers such as constant acceleration, it is necessary to ensure that the orientation of shape is always consistent with the direction of movement.…”

In utilizing a variable-structure multiple-model (VSMM) algorithm for kinematic state estimation, the core step is the model set design. This study aims to refine the existing expected-mode augmentation (EMA) algorithm, a method of model set design. First, the OTSU algorithm is employed to determine an adaptive threshold, which in turn allows for a reasonable partition of the basic model set. Next, a subset of possible models is preserved, reactivating models adjacent to the one with the highest prediction probability, eliminating improbable models, and yielding an augmented expected mode. Additionally, the study leverages the translation properties of radial functions and inverse trigonometric function formulas to derive a maneuvering model for starconvex extended targets under uniformly accelerated conditions. In order to assess the effectiveness of the proposed algorithm and the validity of the established maneuvering model, simulation experiments were carried out in both fixed and random scenarios. The proposed algorithm demonstrates improved performance when compared to the interactive multiple-model algorithm and the unmodified EMA algorithm.

In this paper, we investigated the excessive thermal stress caused by the difference in the coefficient of thermal expansion of the material during the molding process of the adapter. It has led to the bulging phenomenon during the high and low-temperature tests. We analyzed the heat transfer mechanism of the adapter during the high and low-temperature tests by using finite element simulation. We then analyzed the causes of the bulging phenomenon. We successfully solved the bulging problem by using the method of heating up the foamed adapter together with the mold for curing, which provided a new idea for adapter molding.

Cyanate ester (CE) resin is usually used as high-temperature resistant or microwave absorbing material in aerospace field because of its high-glass transition temperature, low-curing shrinkage, and excellent dielectric properties.However, CE resin has the disadvantages of high-curing temperature, high brittleness, and poor toughness, which limits its application in the field of aerospace. In this article, CE resin is modified by high-performance thermoplastic engineering plastic polyether sulfone (PES) to obtain a modified resin with excellent toughness. The thermoplastic/thermosetting semi-interpenetrating network system formed by PES and CE resin can greatly improve the mechanical and thermal properties of PES modified CE resin. The results show that the flexural strength and impact toughness of CE resin castings modified with 10 wt% PES are 56% and 63% higher than those of CE resin castings. At 800 C, the retention weight of CE resin castings with 12.5 wt% PES content increased from 19.0% to 28.1%, which shows that the heat resistance of CE resin is greatly improved by PES. Compared with carbon fiber reinforced CE resin (CF/CE) unidirectional composite, the flexural strength of CF/CE-P-10 composite is increased from 1649.6 to 1959.8 MPa; the interlaminar shear strength is increased from 61.3 to 84.2 MPa; the impact strength is increased from 225.9 to 346.4 kJ/m 2 ; and the interlaminar fracture toughness is increased from 5.34 to 11.38 J/m 2 . K E Y W O R D Scarbon fiber reinforced resin matrix composite, cyanate ester resin, mechanical properties, polyether sulfone, thermal stability | INTRODUCTIONCyanate ester (CE) resin is a kind of high-molecular material with excellent mechanical properties, thermal stability, and dielectric properties, [1] because CE resin forms a highly cross-linked triazine ring network structure in the curing process. However, the triazine ring structure also leads to some disadvantages of high brittleness and risk of fracture for cured CE resin products. Therefore, toughening modification of CE resin is necessary for further broadening its application range.
