Strategic Study of CAE 2004, Volume 6, Issue 1, Pages 30-36
The satellite mobile network is a sky-based communication network whose basic physical architecture is satellite constellation, and it covers the global areas with the communication links between the satellites. The satellite mobile network gives great impetuses to social development, scientific and technical advancement and military normalization, and it gives enormous challenge to the researchers because of the mobile character of the sky-network, the unmeant disconnection of the communication, the complexity of the access, and the integration of the use. It is necessary to use the general concept design simulation to validate general requirement, general project, key technical guideline, and resourceful restrictive condition, and then to form a scientific feasibility report. This paper introduces the general concept of the satellite mobile network, and designs a platform that aims at the simulation of the sky-network, and gains the data of the general concept design simulation of the satellite mobile network with some examples.

Strategic Study of CAE 2001, Volume 3, Issue 1, Pages 31-35
The significance of the theory of modem management and decision making to the research and development of aero-engines in China is discussed. Then by reviewing some successful and unsuccessful examples in and out of China of decision making in research and development of new aero-engines, experiences and lessons in decision making and management are analysed and summarized. It is further stated that several relationships should correctly be handled in connection with the practice in China in the process of research and development of Chinese aeroengines. For the better and faster development of Chinese aero-engines, to practise decision making in a scientific and democratic way will be the first important measure to be taken. At last suggestions for scientific decision making in research and development of Chinese new aeroengines are presented.

Design,manufacture and maintenance of military fighter engine are particularly a lot more difficult to learn than those of other military aero-engines. Owing to military aero-engine is monopolized by very few countries and its core technology is never transferred, it features high risk,high investment,high barrier and high cost. Currently,design and manufacture of military aero-engine in China have not reached the level of independent research and development,instead,the method of long-term dependence on copying or importing others' military engine is adopted to meet the needs. However,after over twenty years of unremitting efforts of some domestic enterprise,Chinese all fighter engines including engines powered in designing aircraft have completely achieved the level of independent maintenance,whose maintenance technology, ability,quality, efficiency and cost have reached or surpassed those of importing nations,with a change developing from nothing and an improvement from weak to strong. In particular, more than ten projects concerning research and development of remanufacturing technology and the engineering application with the feature of independent intellectual property rights have promoted leapfrog improvement of Chinese military aero-engine independent maintenance level,whose function cannot be substituted.

At present China's air emergency rescue ability lags far behind, which urgently requires planning and constructing China's air emergency rescue systems nationwide. As soon as possible, we should work out "the Master Plan for China National Air Emergency Rescue Systems Construction" , strengthen the architecture of air equipment and air infrastructure, set up the administrative agency for the national air anti-disaster and rescue actions, expedite the opening up of the low-altitude airspace, establish the specially-trained air emergency rescue troops, heighten the air emergency rescue capabilities, and build China's national air emergency rescue systems with Chinese characteristics.

Strategic Study of CAE 1999, Volume 1, Issue 2, Pages 24-29
It has been only 50 years since gas turbine engines arrived in the early 40´s, however, there have been great changes in gas turbine technology progress. Gas turbine engines has been playing an important role in the development of aviation industries.Turbofan engines are always at the leading edge in technical area. It has become the major power for modern fighter aircraft and transportation aircraft in the trunk airlines. Thrust-weight ratio, one of the most important technical parameters of fighter aircraft engine, has been improved from 2 in the early time to 8, while the fuel consumption has been reduced from 1.0 kg/daN ▪h to 0. 6～0.7 kg/daN▪h.
From late 40´s to the early of 21st century, there have been four generation replacements of fighter aircraft. Fighter aircraft engine with a thrust-weight ratio of 8 was emerged in early 7O´s. It remains the main model on active service for developed countries today, and is still under development.Fighter aircraft engine with a thrust-weight ratio of 10 is in development, and hopefully will be put into service by 2003. Aeronautically developed countries have been applying their aeroengine research and development program since 80´s, in order to provide themselves with military and commercial advantages.The target is to demonstrate engine technologies of a thrust-weight ratio of 15〜20 and a fuel consumption reduction of 30%〜40% . It is forecasted that this type of engine shall be successfully developed by the year of 2020, which double the engine capability. It shows that the development of aeroengine technologies is being accelerated.
Facing the 21st century of knowledge and economy, challenge and opportunity run together, difficulty and hope go in parallel. We must seize the chance, go along with the trend to speed up the aero technology development in China. Views and proposals are given in this paper.

Supporting seamless global coverage, satellite Internet is an important expansion and extension of terrestrial communication systems, plays a key role in the space–air–ground integrated network, and acts as an important information infrastructure for building China's strength in cyberspace. Developing satellite Internet is of great strategic significance, and corresponding research on its resource management and scheduling is urgently needed. This study illustrates the fundamental concepts and international development frontiers of satellite Internet as well as the basic elements and research progress of satellite Internet resource management and scheduling, identifies the challenges imposed by the new environment and new modes of satellite Internet, and proposes the development strategies. Moreover, it designs a technical route for satellite Internet resource management, including the primary stages of satellite – ground network interconnection, integration of heterogeneous resources, intelligent on-demand service, and native intelligence. In addition, this study proposes the model and architecture of satellite Internet resource management and scheduling, and constructs a key technical system involving high spatio-temporal dynamic resource characterization, multi-dimensional resource time-continuum deterministic analysis, multi-dimensional time-varying capacity pool indexing, and intelligent decision planning. To realize the intelligent and efficient management and scheduling of satellite Internet resources, we should focus on the network characteristics such as resource heterogeneity, dynamic change of network structure, and differentiated service requirements, implement satellite Internet resource management and scheduling according to the optimized technical route, achieve breakthroughs regarding corresponding key technologies, and integrate artificial intelligence technologies into the resource management and scheduling.
