“…In China, the detonation driving technology adopted by Chinese Academy of Sciences has successfully built the shock tunnel JF8 and JF10 which can produce high-quality driving gas source, among which JF10 is the first high enthalpy shock tunnel driven by oxyhydrogen detonation in the world [16] . Many countries have also carried out a large number of flight experiments due to the limitations of wind tunnel experiments, such as NASA's Reentry F Project [17] , Japanese HOPE-X Program [18] , and so on. The data obtained from flight test is accurate, but most of it are used in validation of simulation result because it is difficult to be carried out and it is hard to be the main method of high temperature flow field prediction.…”

Hypersonic vehicles have a very complex trajectory and excellent maneuverability, which makes them effective in breaking the defence of enemy. Due to the strong and sustained infrared radiation emitted when they cruising rapidly in Near Space, researchers have paid attention to the infrared radiation characteristics of hypersonic targets and early warning detection mechanism. In order to acquire infrared radiation characteristics of hypersonic vehicles and collate research in infrared early warning detection technology phylogeny by the way, we have researched the Chinese and foreign progress of infrared radiation made by hypersonic target projectile, plume and the target entirety firstly; then the discussion of main method of infrared warning detection mechanism, technical models and conclusions as well. Lastly we discuss the main research directions in future by combining with the current research progress.

“…For fighter configurations, drop models have been widely used; recent examples being the X‐31 (Klein and Noderer, 1992) and F/A‐18E/F (Chambers, 2009). Subscale drop models of space vehicles such as the Lockheed Martin X‐38 and Japanese HOPE‐X (Yanagihara et al , 2001) have also been employed. Recently, the usage of subscale flight testing has been extended to civil aircraft, such as within the NASA Airstar research program (Chambers, 2009), where scale models are used to explore a larger flight envelope for a civil transport aircraft.…”

PurposeThe purpose of this paper is to present the latest subscale demonstrator aircraft developed at Linköping University. It has been built as part of a study initiated by the Swedish Material Board (FMV) on a Generic Future Fighter aircraft. The paper will cover different aspects of the performed work: from paper study realised by SAAB to the first flight of the scaled demonstrator. The intention of the paper is to describe what has been realised and explain how the work is may be used to fit within aircraft conceptual design.Design/methodology/approachThe approach has been to address the challenges proposed by the customer of the demonstrator, how to design, manufacture and operate a scaled demonstrator of an aircraft study in conceptual design within five months. Similar research projects have been reviewed in order to perform the current work.FindingsThe results obtained so far have led to new questions. In particular, the project indicated that more research is needed within the area of subscale flight testing for usage in aircraft conceptual design, since a scaled demonstrator is likely to answer some questions but will probably open up new ones.Research limitations/implicationsThe current research is just in its infancy and does not bring any final conclusion but does, however, offer several guidelines for future works. Since the aircraft study was an early phase concept study, not much data are available for validation or comparison. Therefore, the paper is not presenting new methods or general conclusions.Practical implicationsResults from a conceptual aircraft study and a realisation of a scaled prototype are presented, which show that scaled flight testing may be used with some restriction in conceptual design.Originality/valueThe value of this paper is to show that universities can be involved in prototype development and can work in close collaboration with industries to address issues and solutions within aircraft conceptual design.

The references at home and abroad are summarized in this paper. This paper introduces the basic concept and the application significance of aerospace plane, the main differences between the aerospace plane and general aircraft, integrated health management system and its compositions of aerospace plane , the development status of health management for aerospace plane in domestic and foreign countries. Especially it recommends special technical experiments in America, Japan and Italy, and analyzes the health management approaches of them. Finally, it also describes the main fault diagnosis methods. Integrated health management of aerospace plane generally involves a series of activities, including signal processing, monitoring, health assessment, failure prediction, decision support, humancomputer interaction, restoring, and so on. In addition, this paper predicts development direction of health management for the aerospace plane.
