This chapter gives an overview of Quickstep processing method, which is relatively a new technique for manufacturing composites. In this chapter, different aspects of Quickstep processing are highlighted. Since Quickstep processing is an Out-Of-Autoclave (OOA) technique, a brief description of autoclave processing is provided. Basic principle of Quickstep processing and functionality of typical Quickstep plant are also explained. Due to changed chemo-rheology, methodology for cure optimization of different prepregs and composites are discussed with examples. This chapter also includes the literature survey of different aerospace materials being investigated in Quickstep, the potential of new materials development for this process, the melding technique, in service capabilities of Quickstep cured samples and journey of Quickstep from patent to commercialization. Although the technique is commercialized now, few suggestions in the end are provided for the improvement of process.

Environmental Simulation

The large-sized space environmental simulation test facility is mainly used for providing thermal radiation environment in high-vacuum, cold and dark space for satellites, spacecraft, lunar spacecraft to carry out whole satellite thermal vacuum test and for large equipment like antenna to carry out tests in TV conditions. Monitoring the spacecraft’s surface optical image or temperature is a main task in space environment simulation test. In previous tests, optical image test mainly took place in a fixed position, so the measuring location and angle are limited. This paper focuses on large spherical space environmental simulation test facility, and designs a large arc-shape high-precision walking device in a space environment simulation test device. It introduces key technology in detail like structure design, thermal design, processes and manufacturing, etc. The test results show that this device can work steadily and reliably under simulation space environments, and the precision exceeds 0.5°.

Interaction Efficiency

There is an urgent need to develop a real-time database (RTDB) to handle large amounts of real-time data, to realize process monitoring of vacuum cold-black environment simulation, cold-black environment data acquisition, fault processing, data storage, etc. This paper conducts real-time database design through network architecture, functional modules, communication interfaces, data management, and transaction scheduling. Simulation test and associated debugging test show that the real-time database can efficiently process large data volume, and the data interaction efficiency is greatly improved to meet the needs of space environment simulation equipment, laying a solid data foundation for subsequent applications.
