Creep life assessment of aero-engine recuperator based on continuum damage mechanics approach

Frontiers of Mechanical Engineering 2021, Volume 17, Issue 4, doi: 10.1007/s11465-022-0702-6

Abstract: The creep life of an aeroengine recuperator is investigated in terms of continuum damage mechanics by using finite element simulations. The effects of the manifold wall thickness and creep properties of brazing filler metal on the operating life of the recuperator are analyzed. Results show that the crack initiates from the brazing filler metal located on the outer surface of the manifold with the wall thickness of 2 mm and propagates throughout the whole region of the brazing filler metal when the creep time reaches 34900 h. The creep life of the recuperator meets the requirement of 40000 h continuous operation when the wall thickness increases to 3.5 mm, but its total weight increases by 15%. Decreasing the minimum creep strain rate with the enhancement of the creep strength of the brazing filler metal presents an obvious effect on the creep life of the recuperator. At the same stress level, the creep rupture time of the recuperator is enhanced by 13 times if the mismatch between the minimum creep rate of the filler and base metal is reduced by 20%.

The Development of Marine Optical Remote Sensing and the Frontiers

Pan Delu,Li Yan

Strategic Study of Chinese Academy of Engineering 2003, Volume 5, Issue 3,   Pages 39-43

Abstract:

The space remote sensing and information technique have become a necessary tool to observe the different scale, different layer and continuous dynamical phenomenon of oceanic resources and environment. The marine remote sensing has more advantage than the normal investigation in the collection of marine environment parameters of several yeas, even several ten years. In the 1970s the international scientists began the real time detection of oceanic environment by means of water leaving radiance measurement from satellite. China has paid great attention and has made great progress in this field since the 1980s. This paper, first, reviews the development of marine optical remote sensing in China over the last 20 years. Secondly, the neads of this technique in national rights and interests, preventing and reducing natural calamities and management and development of marine resources are discussed. Finally, the key technique and frontiers of the application of marine optical remote sensing in the monitoring of marine environment are expounded, such as marine satellite operational monitoring system, accuracy analysis and quantitization, high frequency and long term monitor data collection, the combination application of multi sensor and key technique, etc.
