Abstract. There are precedents both at home and abroad to use virtual reality technology in the field of aerospace industries. The purpose is to improve the training efficiency of the device assembly and make the operators have more intuitive understanding of the safety and the logic of the assemble process. The virtual training system was presented on Zspace environment, which has strong sense of interaction and immersion. After confirming the requirements, designers determine the conceptual frame and iterative prototype of the system. At last, the article proposed the interactive features in terms of software and hardware under different requirements by giving an application example. Keywords: Virtual reality Virtual training Virtual space interactive feature Aerospace application
1 Introduction VR (Virtual Reality, VR) also called as temporary environment or spiritual environment [1]. Computer and electronic technology generate the virtual world. The user can connect with virtual world by hearing, touching, smelling and a series of actions and the interaction causes a change to the objects in the virtual reality environment. Through the closed loop system users can have immersive, immediate feeling [2]. Virtual reality is a natural interaction technology [3]. It reflects the most advanced achievements in the fields of computer technology, computer simulation technology and parallel processing technology [4]. A standard virtual reality system consists of a computer, input/output devices, applications and databases [5]. Virtual training assembly system is a typical application of virtual reality, which has higher requirements of direct operation (DM) method. Through various input devices trainees can do prototype, verification, simulation, assembly path planning and training [6, 7]. Virtual reality technology was mainly used in the field of science education and display in domestic, while in abroad virtual reality were used in training, simulation, testing, and training. © Springer International Publishing Switzerland 2016 A.

Status Quo of Virtual Reality System
Virtual assembly environment can be divided into the following categories: desktop systems, helmet-mounted system, CAVE systems and large-screen projection systems [8]. Several types of systems were shown in Table 1. Table 1. The virtual assembly environment Virtual assembly environment Desktop
