预先研究演示验证试验是在真实或模拟真实的环境条件下,对已经取得突破的单项关键技术进行综合集成验证试验,包括地面及飞行验证试验。预研项目的生存特点决定了对关键技术探索验证的机会有限,一次验证的失误可能导致机会丧失;并且,由于预先研究的主旨是探索新规律、促进技术发展,具有较强的创新性,而大多数演示验证类项目受周期、技术成熟度等因素的影响与制约, Pre-demonstration Demonstration verification tests are integrated and validated tests of single key technologies that have achieved breakthroughs, including ground and flight validation tests, under realistic or simulated real-world conditions. The survival characteristics of the pre-research project determine the limited chances of exploring and verifying the key technologies. A verification error may result in the loss of opportunity. Moreover, since the main purpose of the pre-research project is to explore new laws and promote technological development with strong innovation, Most demonstrations and verification projects are affected and constrained by factors such as cycle, technology maturity,
