A COMS-compatible high Q-factor suspended on-chip spiral inductor used in the radio frequency front-end of radio fuze is designed and fabricated using the micro-electro-mechanical system (MEMS) surface-micromachining technology. The fabrication process of inductor is compatible with CMOS in the aspects of both thermal budget and materials. The loss factors of on-chip spiral inductor are reduced by using a suspended copper coil, and the Q-factor is significantly improved. The improved inductor model is analyzed by the electromagnetic finite element analysis software HFSS. The MEMS suspended on-chip inductor is measured. The measurement results show that the Q-factor of inductor is more than 20 in the frequency range of 1~7.6 GHz and reaches 38 at 7.4 GHz.

In the hardware-in-the-loop simulation system, simulation authenticity mainly depends on whether the hardware-in-the-loop simulation environment is verisimilitude, besides depends on qualified performance of the test object. This paper introduces how to choose the simulation environment device to ensure closed loop of hardware-in-the-loop simulation according to the characteristic of test object's parameters in the laser beam riding guidance missile, and responses the real and reliable physical environment where the object locates. © 2015 Technical Committee on Control Theory, Chinese Association of Automation.

Mixer is a basic RF device for signal transportation and has potential applications in many fields. A novel sub-millimeter mixer device based on MEMS technology has been designed and fabricated. In this design, SU-8 photoresist which has a high dielectric constant, was used as the dielectric layer of the device. The subsequent processes, such as photolithography, electroplating of micro-strip etc., were carried out on SU-8 dielectric layer. By using positive- and negative photoresist sacrifical process, a novel sub-millimeter mixer was demonstrated. ©, 2015, The Editorial Office of Chinese Journal of Sensors and Actuators.

To study the ignition characteristics of aluminium-magnesium fuel-rich propellant, many groups of ignition experiments were carried out under various laser heat flux by using a laser ignition system. The results show that the ignition mechanism of aluminium-magnesium fuel-rich propellant is condensed-phase ignition, and laser heat flux density plays a leading role in the ignition process. When the laser heat flux density is in the range of 176~646 W/cm2, the ignition delay time of aluminium-magnesium fuel-rich propellant increases with the increase of heat flux density, and the ignition delay time changes slowly under high heat flux density. The calculation formula of aluminum-magnesium fuel-rich propellant ignition delay time under various laser heat flux density was given according to experimental results. Under laser heat flux density in the range of 176~646 W/cm2, the ignition delay time of aluminium-magnesium fuel-rich propellant can be calculated by the formula.

To ensure the structure safety of nozzle while working in high-temperature gas flow, it is necessary to estimate the temperature distribution and thermal-structure accurately. Aiming at this problem, the finite element model of complex nozzle was established. The CFD and the thermal and structural analysis part of ANSYS were used to simulate the temperature field and stress field, and the coupled calculation method of thermal-structure was achieved. The results show that the heat-transfer coefficient gets maximum value at throat. From downstream of convergent section to throat, the peak value of temperature appears, and the temperature changes continuously in the same material. The temperature and stress show obvious change of gradient at the interface of different materials, and the stress concentration forms at the interface. The conclusion offers technical support for structural design of nozzle and safety assessment.
